proteins regulate cell process, transport substances into or out of cells, and help
a. regulate blood pressure
b. form bones and muscles
c. control body temperature
d. regulate pH in various parts of the body
Answer:
B
Explanation:
I think it's B since proteins don't control blood pressure or temperature. Also I'm pretty sure they don't regulate the body's PH

Describe the effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme.
Answer:
In an environmental temperature above optimum temperature will cause the enyzmes to denature (deform), because when they denature the subtrate will no longer fit into the enzyme
The effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme - denature the enzyme and lose the specific shape of the enzyme leads to losing its activity.
An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction.extremely high temperatures above the optimum temperature can cause an enzyme to lose its shape (denature) and stop workingThus, the effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme - denature the enzyme and lose the specific shape of the enzyme leads to losing its activity.

A man with blood group B marries with a woman with blood group AB and the daughter has blood group AB. Is this information enough to tell you which of the traits – blood group B or AB is dominant? Why or why not?
Answer:
YES. This information is enough to assume that neither of the blood groups dominates over the other one.
Explanation:
Available data:
A man with blood group B ----> Genotype IBIB or IBiA woman with blood group AB ---> Genotype IAIBTheir daughter has blood group AB --> Genotype IAIBThe fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.
If blood type B was dominant over A or AB, then the daughter should have Blood type B. If blood type A was dominant over B or AB, then the daughter should have Blood type A. Blood type AB tells us that both types are being expressed, A and B.The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.
This is enough information to assume that neither of the blood groups dominates over the other one.

natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or population? explain
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
Which of the following does not exist during prophase?. Single choice.
A. Condensation of chromatins
B. Disappearance of nuclear membrane
C. Pairing of homologous chromosome
D. Chromosomes lined up in the middle of the cell
Option 2
Answer:
Option B.
Disappearance of nuclear memberane.
Explanation:
This is because Prophase is marks the beginning of mitosis, and it is the process where replicated genetic contents are separated into daughter cells. During prophase, ttgere is condensation of chromatin. The chromatin coils and it become compact, which lead to the formation o chromosomes that are visible. The sister chromatids are joined together at the centromere. The mitotic spindle begins to form. The mitotic spindle is consist of long proteins called microtubules that firms at opposite end. The spindle separate the two sister chromatids.

Explain how different forms of a gene are distributed to
offspring.
Answer: During gamete formation, the alleles for each gene segregate from each other, so that each gamete carries only one allele for each gene. an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles.
What are genes?
Genes are an basic physical and functional unit of heredity.Genes are what make our DNA.

Which of the following is a likely impact of this catastrophic event on biodiversity?
Species brought in by the storm surge will displace species native to the coastal wetlands.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity
will increase in these areas.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the
local species, causing a decrease in biodiversity

The main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.
What is the main characteristic of the bacteria domain?All living things are classified into kingdoms based on specific characteristics found in organisms in that kingdom.
For the bacteria kingdom, the main characteristic present is that they lack a well defined nucleus as well as nuclear membrane.
Organisms without a well-defined nucleus are known as prokaryoytes.
