Answer:

Explanation:

Terms in this set (15) Where in the neuron is an action potential initially generated? Axon hillock. this region (first part of the axon) receives local signals (graded potentials) from the soma and dendrites and has a high concentration of voltage-gated Na+ channels.

kenny6666 [7]

Answer:

genotype is responsible for establishing phenotype

Explanation:

When Mendel experimented with pea plants, concept of genes and alleles had not come up yet. Through his experiments Mendel first proved that some type of combination in cells leads to a particular phenotype.

He coined the term "factors" which are today known as alleles. These factors paired up and displayed a particular phenotype. Today we know that the alleles are responsible for a genotype which ultimately results in a phenotype. Hence, he established that genotype is responsible for establishing phenotype even before the term genotype was coined.

Protein X is a protein that is composed of four subunits of equal size--alpha, beta, delta, and gamma--that are bound by either
alexandr402 [8]

Answer:

The correct answer is e3

Explanation:

The given protein in the question proteib X contain four subunits of equal size alpha,beta,delta and gamma which are bound by either noncovalent interactions or disulfide bridges and only beta and delta subunits are bound to each other by disulfide bridges.

  As a result when the protein will undergo fragmentation it will generate 3 bands because the interaction that is present between alpha and beta subunit will break resulting in the formation of 2 bands. Now the most important fact is that the beta subunit is linked to delta subunit by di sulfide bond so when betamarcaptoethanol will act on protein X it will break the disulsulfide bond present between the beta and delta subunit to reduce both the subunit.

  Finally the interaction that is present between delta subunit and gamma subunit will be broken down to release the delta subunit which will form a single band during SDS PAGE..

Explain in detail how to use a microscope.
gtnhenbr [62]

Turn the revolving turret (2) so that the lowest power objective lens (eg. 4x) is clicked into position.  

Place the microscope slide on the stage (6) and fasten it with the stage clips.  

Look at the objective lens (3) and the stage from the side and turn the focus knob (4) so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip.  

Look through the eyepiece (1) and move the focus knob until the image comes into focus.  

Adjust the condenser (7) and light intensity for the greatest amount of light.  

Move the microscope slide around until the sample is in the centre of the field of view (what you see).  

Use the focus knob (4) to place the sample into focus and readjust the condenser (7) and light intensity for the clearest image (with low power objectives you might need to reduce the light intensity or shut the condenser).

When you have a clear image of your sample with the lowest power objective, you can change to the next objective lenses. You might need to readjust the sample into focus and/or readjust the condenser and light intensity. If you cannot focus on your specimen, repeat steps 3 through 5 with the higher power objective lens in place. Do not let the objective lens touch the slide!

When finished, lower the stage, click the low power lens into position and remove the slide.  

Your microscope slide should be prepared with a coverslip over the sample to protect the objective lenses if they touch the slide.  

Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.  

Always keep your microscope covered when not in use.  

Always carry a microscope with both hands. Grasp the arm with one hand and place the other hand under the base for support.

Given the following events involved in the regulation of blood volume, which one of the following answers best represents the or
Ad libitum [116K]

Answer:

The correct answer will be-

1. decrease in blood volume

2. secretion of renin from juxtaglomerular apparatus

3. production of angiotensin II

4.  secretion of aldosterone

5. sodium reabsorbed from distal tubules and collecting ducts

Explanation:

The RAAS pathway or Renin-angiotensin II-aldosterone pathway gets activated in the human body to maintain the osmolarity and blood volume.

When the receptors in the blood sense the low volume of water in the body sends signals to the brain which activates the secretion of the renin from the juxtaglomerular cells. Renin helps converts the inactive angiotensin to angiotensin I and II which help reabsorption of sodium ions. This activates the production of aldosterone which increases the reabsorption of the sodium ions into distal and collecting ducts.
