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.

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.

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.

R represents the allele for red hair, and r represents the allele for white hair.
Which best describes this inheritance pattern?
A) Incomplete dominance because the intermediate form of the trait is chosen
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.

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.

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'.

Answer:
The answer is
2. magnetism and fluorescence
Explanation:
The other properties mentioned are common properties that are used to identify all minerals. As you can see, hardness, color and fracture are common properties that cut across all minerals. Magnetism and fluorescence however, are not very common and are found in only a few special minerals. That is why they are considered special properties.
Hope this helps!
magnetism and fluorescence are considered two of the special properties that are used to identify certain minerals. Thus option B is correct.
what are the properties to identify an object ?
Minerals are the chemical compound which has a well -defined composition and a specific crystal structure and occurs naturally in the pure form.
If a compound occurs naturally in different crystal form then it is referred as a different mineral. The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.
Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure; it has variable composition which is split into separate species.
minerals include color, streak, luster, specific gravity and cleavage as their physical properties, shows no magnetism. Basically magnetism is the physical property of the minerals, magnetism does not have these elements. thus, have no magnetism called diamagnetic. Examples of diamagnetic are quartz, apatite and calcite.
