Most enzymes can function within a rather broad pH range, approximately 3-12.

Leni [432]

Answer:

The Question is incomplete. Here should be the complete question.

Based on what you have learned about how cells ensure that proteins end up in the right place (Chapter 7), what type of signal would you expect to be exposed on a cytosolic receptor after a steroid hormone changes the receptor's conformation?

Amino acids required for transport through the nuclear pore complex

Initiating an action potential

Under most circumstances, once an axon's membrane potential reaches threshold (about -55 mV in mammals), an action potential is automatically triggered. The graph below shows the changes in membrane potential that occur in an axon membrane that is initially at resting potential.

In response to a stimulus, the membrane slowly depolarizes until the membrane potential reaches a particular value, called threshold. At threshold, a rapid depolarization of the membrane occurs and an action potential is initiated.

Drag the labels onto the flowchart to show the sequence of events that occurs once

the membrane potential

-1. membrane potential reaches threshold

-2. Na+ ions rush into the cell

-3. membrane potential rises (depolarizes) rapidly

-4. many Na+ voltage-gated channels open

The ANSWER WILL SURELY BE

membrane potential reaches threshold ---> many Na+ voltage-gated channels open ---> Na+ ions rush into the cell ---> membrane potential rises (depolarizes) rapidly

(1--->4--->2--->3)

How an immune response stars after a macrophage attacks a pathogen

marishachu [46]

After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.

g a true breeding pea plant with round and green seeds was crossed to a true-breeding pea plant with wrinkled and yellow seeds.

Sveta_85 [38]

Answer:

The probability of producing a round and green plant from this cross is 3/16

Explanation:

This question involves two distinct genes coding for seed shape and seed colour. In the seed shape gene, allele for round seeds (R) is dominant over allele for wrinked seeds (r), while in the seed colour gene, allele for yellow seed (Y) is dominant over allele for green seeds (y).

A truebreeding plant means that the plant possesses homozygous genotype. Hence, a truebreeding pea plant with round and green seeds will have genotype: RRyy while true-breeding pea plant with wrinkled and yellow seeds will have genotype: rrYY. These two parents will produce F1 offsprings with genotype: RrYy (heterozygous).

When the F1 offsprings are self-crossed (RrYy × RrYy), the following allelic combinations of gametes will be produced by each F1 parent: RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible F2 offsprings with a phenotypic ratio 9:3:3:1 will be produced

9- Round yellow offsprings (R_Y_)

3- Round green offsprings (R_yy)

3- Wrinkled yellow offsprings (rrY_)

1- Wrinkled green offsprings (rryy)

When polymerization of a protein is complete, but a protein is still completely linear, what is the highest level of structure i

Dominik [7]

Answer:

hello there

Explanation:

When polymerization of a protein is complete, but the protein is still completely linear, the highest level of protein structure that has been completed is the primary level.

What personal story does Lou share to illustrate the broken judicial system at work? Explain and analyze why this story speaks t

Nuetrik [128]

Answer:

Melanoma is the type of cancer Mary Lou had, Sunburns in adulthood assume to be the mostly associated with melanoma. Melanoma, the most severe type of skin cancer, develops in the cells (melanocytes) that produce melanin — the pigment that gives your skin its colour. Melanoma can be also apear in your eyes and, rarely, in internal organs, such as your intestines.

Explanation:

1. Describe the unspoken culture in Mississippi. How does this compare to any unspoken culture that you’re aware of where you live? Explain.

The death penalty is part of the unspoken culture. If you murder someone you are going to receive the death penalty. Idaho has only executed 23 people since 1977. So not as much as Mississippi.

5. What are your thoughts on the death penalty? Do you believe that people are less likely to commit murder or violent crimes in states that have the death penalty? Evaluate and explain. I believe in the death penalty based on the crime committed. And yes I think less people would commit crimes if we actually went through with the death penalty.
