Describe how viruses and prions can alter cell functions

Biology
1 answer:
larisa [96]3 years ago
6 0

Hi

<em>As we are well aware with two great properties that are present in both viruses and prions, i.e Ability to reproduce.</em>

Prions are basically very tiny little organisms which are considered to be even smaller than viruses, their structure consists of proteins in folded form and are capable to induce abnormal folding of proteins in certain vital proteins found in Human and some other animal brains, therefore when the enter in brain organ they multiply there rapidly and alter the function of proteins  by altering their folding patterns and thus confer harm to the host.

If we talk about viruses they are non living entities outside the living host but once they enter living host they get an ability to live and reproduce. When they reproduce very abruptly in host organs or tissues, they often take the control of host cells and force them to produce materials for their own longevity and life, and in this way alter the host metabolism and organ functionality.

Hope it helps!

In a plant, red flower color is incompletely dominant over yellow. What will the distribution of flowers in the F2 hybrids be if
Simora [160]
A Punnett square would help here. 

Let's say (R) is dominant red and (r) is recessive red, aka yellow. 

You start with F1 hybrid flowers that are all (Rr) - these are all <em>orange</em>. So when they reproduce, both parents are (Rr). When you create a Punnett square, you'll see that the results for the F2 generation are (RR), (rr), and (Rr) twice. 

(RR) is red, (rr) is yellow, and (Rr) is orange, just like the F1 generation.

What connects the proximal and distal convoluted tubules?
Katena32 [7]
I believe that the loop of Henle is the hairpin structure that connects the proximal and distal convoluted tubules. The loop of Henle is composed of the ascending and the descending limb. The descending loop of Henle connects the proximal convoluted tube with the ascending limb of the loop of Henle, while the ascending loop of Henle connects the descending limb of the loop of Henle with the distal convoluted tubule.

Design a laboratory-based experiment to test the hypothesis that algae need light to grow.
Shalnov [3]

The same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

<h3>What is algae growth?</h3>

The growth of algae is the process by which the organism increases in size. Now we know that that the algae is photosynthetic hence light must be required for its growth.

In order to verify this, the same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

The results of this experiment must confirm that the algae exposed to light grows better than the algae that was not exposed to light.
