(a) Describe the biological need for cells to be surrounded by a membrane that is selectively permeable for different materials

Biology
1 answer:
seropon [69]3 years ago
6 0

Answer:

The selectively permeable membrane is important because it will allow only those materials and ions to pass which are required by a cell. The selectively permeable cell membrane is important to maintain the homeostatic conditions for a cell. It actively maintains the internal cell environment.

If cell membrane was not permeable then toxic molecules and ions as well as waste elements would enter the cell destroying the cell. An increase in the amount of ions in the cell might have caused the cell to burst.

3. Which is not an example of symbiosis?
S_A_V [24]

Answer:

The correct answer is B. generalism.

Explanation:

Mutualism is a symbiotic relationship wherein both organisms benefit from the other’s presence. Parasitism is a symbiotic relationship wherein one organism benefits at the expense of the other organism, which is harmed. Finally, commensalism is a symbiotic relationship wherein one organism benefits and the other is neither helped nor harmed. Generalism does not refer to a symbiotic relationship and thus is the correct response.

Hope this helps!

Two true-breeding stocks of pea plants are crossed. one parent has red, axial flowers and theother has white, terminal flowers;
xxTIMURxx [149]
This is a typical case of a dihybrid cross. 
From the phenotype of the offspring, we can conclude that the gene for the red color of the flower and the gene for the axial position of the flower are dominant.
Since we know that the ratio of phenotypes in a dihybrid cross of independently inherited alleles is
9(dominant for both traits)
3(dominant for one trait, recessive for the other)
3(dominant for the second trait, recessive for the other)
1(recessive for both traits)
we can expect 3/16 of the f2 generation to be dominamt for one trait and recessive for the other (red, terminal flowers), or to be precise 190 individuals.
