Answer:
Sensory neuron
Explanation:
There are the major classifications to neurons - sensory, motor and inter relay.
All these neurons helps in the relay of signals from the environment to the CNS where these signals are interrupted and actions are Carrie out. The sensory neurons begins this order and help in the relay of sensation from external stimuli.
Thus since Jerry has no sensations in his injured legs, it means he is unable to detect or feel external stimuli/or there is a damage to the sensory neurons in the region of his legs which prevents the relay of information to the CNS.

Answer: The attachment listed some cell organelles,although there isn't a specific question on then but am going to be defining each of them and state their functions as well.
1. The Nucleus; The is command centre of the cell, it is made up of nuleolus, chromosomes, nucleoplasm,nuclear envelope and nuclear lamina.
it contains the genetic/hereditary materials that the cell is made up of.
The Nucleus plays a great role in the control of growth and development of the cell.
The nucleus also coordinates some of the the activities of the cell like cell division and protein synthesis.
2. Cytoplasm; The cytoplasm is one of the cell organelles,it is the liquid portion of the cell,it consists of cell contents between the plasma and the cell membrane. The fluid cytoplasmic material is where many cell organelles are found/suspended fluid. Most activities carried out by the cell occurs in the cytoplasm.
3. Endoplasmic Reticulum; The Endoplasmic Reticulum is one of the cell organelles that have the structure of a network of flattened sacs and tubules and play a crucial role in plant and animal cell. Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes in them thus giving it the smooth appearance.
The Endoplasmic Reticulum functions in the production, processing, and transport of proteins and in and out of the cell and also the production of lipids.
4. Golgi Body; One of the plant organelles that plays a role in the sorting and organizing the proteins produced and processed by the Endoplasmic Reticulum. these proteins are sorted and packed in vessicles to be used by the body.
5. Mitochondria; (a double membrane organelle). It is otherwise known as the powerhouse of the cell,it produce/generate energy in the form of ATP needed for cellular respiration. These energy produced is used for other cellular metabolic activities.
6. Lysosome (Animal) Chloroplast (Plant); Lysosomes are found in most animal cells, they function by digesting good and garbage,they contains acids that aids this function in the stomach of the cell and when the lysosome is diseased or explodes,the cell stops functioning.
The Chloroplast on the other hand is found in the cells of plants and algae,they play a crucial broke in photosynthesis by capturing the energy from the sun and turning the captured energy into usable forms like sugar,glucose and other organic molecules.
7. Cell Membrane; The cell membrane is the cell organelle that forms a boundary between the cell and the sorounding environment.
The cell membrane as well controls the movement of cellular materials in and out of the cell.
8. Nucleolus; The nucleolus is one of the cell organelles where ribosomes are made. The ribosomes are small grain-shaped organelles that make protein and they are found in the surface of rough Endoplasmic Reticulum. Nucleolus are small and round in structure and are found in the nucleus,
9. Vacoule (Plant Cells) Centrioles (Animal Cells); The vacoule is a storage chamber(reservoir) for wanted and unwanted materials in the cell, the vacoule is found within the cytoplasm and it is enclosed by a membrane that typically contains fluid.
The centrioles on the part of the animal cell is a cell organelle that has a structure of a two hollow cylinders,ring of microtubules next to each other(the centrosome).the centrioles are located just outside the nucleus of the cell.
Centrioles function by producing the mitotic spindles for cell division, and also assisting to pull chromosome pairs apart to opposite end of the cell during cell division.
10. Cell Wall; A protective semi permeable rigid outer layer of nonliving material that surrounds the cells of plants and some other organisms.
The cell wall houses the organelles of the plant cell.
The cell wall functions by giving the cell strength and structure,it's semi permeable nature filters and selectively allows certain materials in and out of the cell.

How do catalyst work?
Answer:
Catalysts increase the reaction rate of a chemical reaction, allowing it to use less energy to start a chemical reaction and doesn't change the chemical properties or formulas.
Explanation:
What is a substrate? a molecule that acts as a catalyst a place where the reaction occurs a place on the product where the enzyme fits a reactant that is catalyzed by an enzyme
Answer:
a reactant that is catalyzed by an enzyme
Explanation:
Reactants are often referrred to as substrates as those are what enzymes mostly act upon to create products or some desired consequence
Option (d). a reactant that is catalyzed by an enzyme is called the substrate.
SubstrateA substrate exists as a molecule on which an enzyme acts. Enzymes catalyze chemical reactions that concern substrate, where the substrate binds to the enzyme's active site, and an enzyme-substrate complex is created. By action of the enzyme, the substrate exists transformed into a product, released from the active site, and free to obtain another substrate.
Enzyme catalysis exists as the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes exist in proteins, and most such processes are chemical reactions. Within the enzyme, naturally, catalysis happens at a localized site, called the active site.
The reactant in an enzyme-catalyzed reaction is named a substrate.
Because enzymes can expand reaction rates by enormous factors (up to 1017 times the uncatalyzed rate) and tend to be very precise, typically producing only a single product in quantitative yield, they exist the focus of active research.
Hence, Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

How did the death of chestnut tree result in the growth of the ecosystem
Answer:
add nutrients to the soil.
Explanation:
The death of chestnut tree result in the growth of the ecosystem because when the chestnut tree dies, the decomposers such as fungi and bacteria start feeding on the dead tree and as a result nitrogenous waste is produced mixed with soil which is the essential nutrient for the plants. These nitrogenous waste is used by the plants to make amino acids and as a result the growth of an ecosystem occurs.

A particular protein (Vac8) found in yeast has this N-terminal sequence, Met-Gly-Ser-Ser-Cys.... The corresponding DNA sequence in the coding strand is 5' ATG GGC TCA TCG TGC.... If the DNA sequence is mutated to 5' CTG GGC TCA TCG TGC..., what will happen to this VAC8 gene? (in RNA, CUG codes for Leu)
Answer:
The protein will not be synthesized because this point mutation produces the loss of the start codon (substitution of Met by Leu).
Explanation:
The mutations are changes in the DNA sequence that have diverse effects on protein synthesis. A mutation in the start AUG codon may lead to the reduction and even the elimination of protein synthesis. In consequence, this type of point mutation is usually referred to as 'start-loss mutation'.
Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others,
they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at
locating and capturing prey.
Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting
behavior of bats be affected by such an environment?
A
Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
B.
C.
Bats would be unable to use echolocation, which would prevent them from finding any prey.
Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase.
Bats would be better able to use echolocation, which would improve their ability to find prey.
D.
Answer:
A
Simply the noise from heavy traffic will cause the destructive interference which reduces the echolocation,blocking the echoes and therefore prevent prey location for bats.
Generally this reduces the Bats' population, as some could not rely on the echo to locate the prey, leading to starving and death. Thus each bat needs to rely on the individual echolocation from the prey to survive as new hunting adaptation.Since the echolocations has been blocked
Answer:
Bats would be unable to use echolocation, which would prevent them from finding any prey.

You are now taking a ride on the Magic School Bus with Ms. Frizzle. This bus is magic because it can go anywhere within the body. Today’s lesson is on Central Dogma. Ms. Frizzle takes your class directly to the nucleus to start your field trip. Since this trip is about the central dogma, what three major cellular process will be involved? Where will you bus be going within the cell during each of these processes? For each process, describe in your own words and in general what is going on?
Answer:
See the answer below
Explanation:
The trip will involve a bit of stoppage inside the nucleus during which replication and transcription will take place before proceeding to the cytoplasm where synthesized mRNA will become translated into protein.
The central dogma refers to a series of processes during which genetic information in the DNA of a cell is encoded and expressed in living cells. The 3 major steps involved in these processes are:
1. Replication
2. Transcription
3. Translation
Replication involves the synthesis of a double-stranded DNA molecule from a template of another double-stranded DNA molecule within the nucleus. In order words, replication is a process during which a DNA molecule reproduces itself. Each of the strands of the DNA acts as a template for the synthesis of another new strand. Eventually, 2 new double-strand DNA molecules are formed each consisting of one old strand and one new strand.
During transcription, the information contained in deoxyribonucleic acids is encoded and transcribed into another molecule known as the messenger ribonucleic acid. This process happens in the nucleus of the cell.
After transcription and processing of the mRNA produced, the resulting mRNA is then transported to the cytoplasm where, together with the ribosome and transfer RNA, the encoded information becomes translated into protein. Each of the genetic codes in the mRNA is translated to their respective amino acids and the amino acids are linked together by peptide bonds to form a protein.
Key deer are found only on certain islands in the Florida Keys. Populations are typically small enough that genetic drift has caused significant deviation among populations on different islands. For example, the population on No Name Key has allele frequencies of A1 = 0.43 and A2 = 0.57 while the population on Big Pine Key has allele frequencies of A1 =0.21 and A2 = 0.79. Construction of roads has recently increased migration rates between these populations to approximately 0.08 per generation. What will the frequency of A1 be on Big Pine Key after a single generation of migration from No Name Key?
Answer:
The frequency of A1 be on Big Pine Key after a single generation of migration from No Name Keyp is 0.2276
Explanation:
Whenever it occurs migration between two populations, there is genetic flux going on. Genetic flux might be considered as an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flux acts homogenizing the allelic frequencies between the two populations, and it might introduce variability.
By knowing the allelic frequencies in both populations at a certain time and the migration rate, we can calculate the allelic frequencies of populations in the next generation. This is:
pA₂=pA₁(1-m)+pB₁ m
pB₂=pB₁(1-m)+pA₁ m
Being
A one population and B the other population pA₁ and pB₁ the frequencies of the p allele before migration, pA₂and pB₂ the frequencies of the p allele after migration, m the migration rateIn the exposed example, we know that:
No Name Key population allelic frequency: A1 = 0.43 and A2 = 0.57Big Pine Key population allelic frequency: A1 =0.21 and A2 = 0.79Migration rate m=0.08Let´s say that p represents A1 allele, and q represents A2 allele.
The frequency of A1 allele (p) be on Big Pine Key (Population B) after a single generation of migration from No Name Key (Population A)
pB₂=pB₁(1-m)+pA₁ m
pB₂=0.21 x (1 - 0.08) + 0.43 x 0.08
pB₂= 0.2276
The allelic frequency in a population after one generation is the allelic frequency of individuals of that population that did not migrate (21 x (1 - 0.08) plus the allelic frequency of the new individuals that came from the other population (0.43 x 0.08).
You can corroborate your result by calculating the q allele frequency in the next generation and summing both of them up. The result should be one.
qB₂= qB₁(1-m)+qA₁ m
qB₂= 0.79 x (1 - 0.08) + 0.57 x 0.08
qB₂= 0.7724
p + q = 1
0.2276 + 0.7724 = 1

Besides the HCT, what other component of blood could be measured to give a better understanding of oxygen-carrying capacity? Explain your answer.
Answer:
The haemoglobin levels or counts can be used.
Explanation:
The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with 4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.
Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.
Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological man.
Therefore fluctuations in the levels of these values below the set points is an indicator of distortion in the oxygen carrying capacity of the blood.
The amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.
Hematocrit refers to the volume percentage of the red blood cells in the blood. Oxygen-carrying capacity can be measured by several techniques.
The co-oximetry and Arterial Blood Gas can be used to determine the oxygen-carrying capacity.
The techniques can be explained as:
Co-oximetry is a type of blood test used to measure the oxygen-carrying capacity of the hemoglobin in the blood. The test uses the light of different wavelengths that can pass through the blood to determine oxygen capacity. Arterial blood gas or ABG test is a type of blood test used to measure the pH and oxygen-carrying capacity of the blood present in the artery. It is used to determine the efficiency of the lungs to exchange the gas oxygen and carbon dioxide from the blood.
Thus, the co-oximetry and ABG test can be used to determine oxygen levels in the blood.

B) Co-dominance because the intermediate form of the trait is chosen C) Incomplete dominance because the offspring display alleles for both hair colors
D) Co-dominance because the offspring display alleles for both hair colors
Answer:
A
Explanation
the red haired trait is dominant over the white haired trait. and the results are all red haired offspring. therefore its incomplete dominance
The correct option is D) Co-dominance because the offspring display alleles for both hair colors.
What is Co-dominance?Co-dominance refers to a phenomena, in which both alleles are simultaneously expressed in the heterozygote.
Incomplete dominance is closely related to Co-dominance in which phenotype of the progeny is intermediate of the parent phenotype.
Here, the red haired trait is dominant over the white haired trait and still both alleles are simultaneously expressed in the heterozygote of the offspring with red and white hair traits, thus, the Co-dominance best describes this inheritance pattern.
