Stem cell transplants may someday be used to treat Parkinson's disease. Researchers are hopeful that these cells would alleviate the symptoms of Parkinson's disease by
Answer:
Researchers are hopeful that these cells would alleviate the symptoms of Parkinson's disease by secreting the neurotransmitter dopamine.
Explanation:
Dopamine is a neurotransmitter released by the brain that plays a role in pain processing at various levels of the central nervous system. This includes the spinal cord, periaduectal gray matter, the thalamus, the basal ganglia, the insular cortex, and the cingulate cortex. Low dopamine levels are associated with the painful symptoms that frequently occur in Parkinson's disease. Parkinson's is generated from a neurodegenerative disorder that mainly affects dopaminergic neurons, responsible for producing and secreting dopamine within the brain. When these neurons degenerate, dopamine levels decrease and the consequences are tremor, muscle stiffness and difficulty making voluntary movements, among others. In Parkinson's disease, there is a loss of dopaminergic neurons and a potential treatment would be that the lost neurons could somehow be replaced. One possibility is to transplant stem cells that differentiate into dopamine-producing nerve cells.

The central (Haversian) canal that runs through the core of each osteon is the site of ________. adipose tissue and nerve fibers cartilage and interstitial lamellae blood vessels yellow marrow and spicules
Answer:
Blood vessels and nerve fibers
Explanation:
The Haversian canal serves as the bone tissues and it runs through the core of each osteon. The osteon surrounds the Haversian canal and contain structures called lamellae.
These lamella are made largely of collagen fibers and also various network of rich blood vessels and cells which produces blood cells in the body. Nerve cells which helps in the relay of impulses are also present. The rich contents of the bone gives it its strength and durability.
Answer:
The correct answer is: blood vessels and nerve fibers.
Explanation:
Haversian Canals are a group of tubes that are located in the more peripheral region of the bone, known as the cortical bone. The cortical bone is hard and compact and is composed of several concentric layers of bone cells (osteocytes and osteoblasts) that circle around a haversian canal, which contains capillaries and nerve fibers. This structure is called an osteon.
Haversian Canals are very important for the correct functioning of the bone, as they give the cells their needed blood supply and innervation.
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.

If evolution is based upon there being genetic diversity between generations, how does the lack of genetic differences existing between daughter cells created via mitosis impact the theory of evolution
Answer:
See the answer below
Explanation:
If evolution is based upon genetic diversity, it means that evolution in organisms that only reproduce by mitotic division will depend largely on the frequency of random mutation of genes.
The only way that genetic diversity can occur between daughter cells formed from mitosis is if mutation takes place. Mutation general means a sudden change to the gene sequence of an organism.
Without mutation, evolution in mitotic organisms will be non-existence because there are no new genes or alleles being introduced into the gene pool.

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'.
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.

You are interested in studying if scalloped alleles follow the expected Mendelian inheritance patterns. What crosses will best allow you to study the inheritance pattern from a single generation and why?
Answer:
Reciprocal crosses
Explanation:
Reciprocal cross is crossing in all possible ways. Such that a parent used as a male can be further used as a female while the parents used as a female can be used as a male. This cross helps to show if indeed the inheritance follows the simple mendelian pattern of inheritance if not the inheritance is somewhat complex and an allele of the gene has more domineering power over the other when used as a specific parents.
The first cross will be between the parental genotypes to obtain the first filial generation offspring. This crosses will be done on both ways
Example
AA × bb
Where AA is the female and bb is the male
bb × AA
Here bb has been used as female while AA is used as a male
If the offspring of the two crosses are the same there is no reciprocal difference and the pattern of inheritance is mendelian fashion if they are different there is reciprocal differences.

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.
PLSSSS 30 POINTSS BRAINLEST
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.
