Answer:
Holds the genetic makeup of the virus. it contains the instruction of what the virus should do and how it should do it and so on.
Autotrophs and Heterotrophs benefit each other by providing raw materials for various life processes ,directly or indirectly .
Explanation:
- Autotrophs can prepare their own food by using sunlight .This is not possible for Heterotrophs. Heterotrophs obtain their food from Autotrophs.
- Heterotrophs Feed on Plants and helps them in Pollination and Seed dispersal.
- Autotrophs Carry out photosynthesis and produce oxygen which is taken up by heterotrophs for respiration. Heterotrophs in turn, give out Carbon dioxide which is used up by autotrophs.
- Heterotrophs like detrivores and decomposers obtain there food from decaying plant parts and thus break down the nutrient which is then made available to plants.
Answer:
Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.
Explanation:
There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:
1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.
2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.
Answer:
four quadrant, nine regions, abdomen or superficial organ
Explanation:
The body ventral side consists of abdominal and pelvic cavities that are primarily the digestive and reproductive system. The four quardrants helps in determing the site for performing surgery, also location of tumors mass. The nine region provide the information about origin of pain associated with the particular organ located in the cavity.
The abdominopelvic cavity can be divided into a total of <u>four</u> quadrants or <u>nine </u>regions. The central point of reference for dividing the abdominopelvic cavity into quadrants or regions is the <u>abdomen or superficial organ. </u>
<span>By producing melanin (pigment), the skin protects the underlying structures from ultraviolet light's harmful rays while producing vitamin D, which works with calcium for multiple body processes.

Vitamin D is produced by the skin when it is exposed to the sunlight. Ultraviolet B (UVB) is the part of the sun's rays that affects the skin to produce such vitamin.
