1 answer:

8 0

It would depend on the method of decolorization. The most common one is by using Acetone-alcohol. When your slide are decolorized too much with Acetone-alcohol, cells will appear to be pink since the crystal violet are washed out.

What is the major difference between bacterial chromosomes and eukaryotic chromosomes?.

Grace [21]

The major difference between bacterial chromosomes and eukaryotic chromosomes is Bacteria have a single circular chromosome whereas eukaryotes have several linear chromosomes.

What is a bacterial chromosome called?

Bacterial chromosome is called nucleoid. It is an irregularly shaped and contains genetic material. It is also called as genophore.

What is meant by eukaryotic chromosome?

Eukaryotic chromosomes are found in the cell's nucleus.
The DNA inside the nucleus is organized into chromosomes. At the most basic level, a chromosome is a molecule of DNA that is tightly coiled around proteins called histones.

What is the difference between bacterial and human chromosome?

Bacterial chromosomes are circular in contrast to human chromosomes, which are linear.
Furthermore, bacterial circular chromosomes are found in the nucleoid area rather than the nucleus, an organelle that is membrane-bound.

Which of the following is an accurate definition of carrying capacity?

Zinaida [17]

Answer: B. The number of individuals that a habitat can sustain with the resources that it has available.

Explanation:

A carrying capacity is the number of individuals of the population belonging to a particular species that an habitat or region or ecosystem can support or sustain in terms of providing the resources. If the population exceeds over the carrying capacity then this results in decline in members of the population.

According to the above description the accurate definition of carrying capacity is B.

Alexis is out mowing the lawn and starts to feel dehydrated. Her ______ will secrete vasopressin. A patient suffering from sever

adoni [48]

1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).

Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).

It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.

2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.

Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.

Under natural conditions, which of the following may cause allele frequencies to change? A. Limited resources, which could cause

jasenka [17]

The answer is A. Limited resources will result in stiff competition among individuals in the population. This will result in differential survival across the population because only the individuals that are able to outcompete the others will be able to reproduce and pass their genes to the next generation. This, therefore, will change the allelic frequency of the population.
