When a piece of liver is dropped into hydrogen peroxide, the peroxide bubbles vigorously as the hydrogen peroxide (H2O2) decomposes. However, if the liver is cooked first, the reaction fails to occur. The reason for this is

a. heating kills the germs that cause the bubbling

b. heating damages the enzyme in liver that breaks down hydrogen peroxide

c. heating removes the water and oxygen from the liver

d. reactions take place faster at lower temperatures

Answers

Answer 1

Based on the nature of enzymes, heating damages the enzyme in liver that breaks down hydrogen peroxide

What are enzymes?

Enzymes are organic molecules which catalyze biological reactions.

Some properties of enzymes include:

most enzymes are proteinsthey are denatured by heatEnzymes are specific in their action

Carbon dioxide consumption

Carbon dioxide consumption can be used to measure primary productivity in an ecosystem.

Primary productivity refers to the rate at which energy is converted to organic material by photosynthesis.

Primary productivity can be calculated by analyzing the change in biomass of producer organisms.

Primary productivity can also be calculated by analyzing the movement of carbon dioxide (consumption).

Primary productivity can also be estimated by analyzing the movement of carbon dioxide the movement of oxygen over time.

Can the effects of UV light on folate explain the full variation of human skin color that exists among human populations today? Explain your reasoning

Answers

The greater amount of eumelanin in darker skin protects folate from being broken down by UV radiation and thus increases fitness among populations in high-intensity UV areas. ... However, it does not explain why there is variation in human skin color.

Human skin colour is due to a pigment called melanin. The melanin pigment is present in outer layer of skin cells. UV light causes increase in production of melanin resulting in darker skin shade.

Why the human skin colour varies?

UV radiation can cause photolysis of folate. This can lower the level of folate. If the level of melanin increase, it will stop the breakdown of folate. This will result in variation of colour in high intensive UV areas.

Thus, it can be concluded that increased UV radiation can cause variation in human skin colour.

Answers

Natural selection results in adaptation, increasing in the individual's fitness. Option C. Features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.

What is natural selection?

Natural selection is an evolutive force.

It selects beneficial alleles in a population and increases their frequency.

It is the result of the phenotype-environment interaction which determines gene destiny in space and time.

Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.

Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.

In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

In the exposed example, the features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.

selective pressure ⇒ competition for resources

influence in fitness ⇒ increase survival and reproductive success.

Use the data to explain the changes in phenotypic frequency from generation 1 to 3.
Do you think this population is in Hardy-Weinberg equilibrium? Provide reasoning to support your claim.

Answers

The phenotypic frequency from generations 1 to 3 shows there are naturally more individuals with the dominant trait. Moreover, changes in frequency show this population does not have Hardy Weinberg equilibrium.

What are the changes in phenotypic frequency?

Phenotypic frequency refers to how common a trait is in one population. In this case, the number of individuals with a recessive vs those with a dominant trait.

From the information provided in the chart, we can see in the first three generations there is a higher number of individuals with a dominant trait, which is genetically natural, and this occurs even as the population grows.

Is there Hardy Weinberg Equilibrium?

Hardy Weinberg Equilibrium is a principle that establishes under normal conditions phenotypic frequency should be constant. This does not occur in this population because by generation 6 there is almost the same number of individuals with a dominant and a recessive trait, which shows phenotypic frequency is changing.
