3. Decreased variation in the shades of red because no form of the trait is advantageous.
viruses are tiny bundles of genetic material which is carried in a viral coat.
<u>Explanation:</u>
- The virus is generally a parasite that needs a host to become active and to reproduce. It cannot reproduce without the host.
- The tiny bundle consists of genetic material and protein. The virus consists of capsid and nucleic acid. This capsid is said to be the protein coat.
- This capsid consists of either RNA or DNA. virus replicate themself within the host body by using its genetic material along with the mechanism of the host.
- Thus after replicating the virus need to get out of host cell, It is performed by two types budding or lysis( bursting the host cell ).
Answer:
Because Intercalary meristems are found in the the stem part of the sugarcane in whole length.
Explanation:
- As we have studied about meristem regions, that these are the regions found at the nodal areas which are able of cell division and growth. Intercalary meristem are present in the nodes of sugarcane stem which lead to the rapid increase in elongation of stem.
- Intercalary meristem are located at the base of leaves and nodes that leads to the increase in length.
-
On the tip of sugarcane, apical or tip region meristem are found. When the tip region is removed, the presence of intercalary meristems play the role by facilitating the elongation of stems in sugarcane.

Answer:
The correct answer would be C) It increases survival for cuckoos, but decreases survival of the other birds.
The host chicks often face lots of competition from the cuckoo chicks in terms of food as well as space. It makes it difficult for the host chicks to survive.
It has also been found that cuckoo chicks beg to be fed more intensely due to which host chick die due to starvation.
In addition, in some species of cuckoo, cuckoo chicks remove host eggs from the nest within few days of hatching.
