Answer:
46
Explanation:
In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. A human egg is haploid (has 23 chromosomes) and a sperm is haploid (has 23 chromosomes). Upon fertilization, the new baby now has the 'correct' human number of 46 chromosomes in each of its somatic cells.
Answer:
Option (A)
Explanation:
Upwelling usually refers to the rising up of denser, deep-sea cold water to the surface of the ocean, replacing the less dense warm air.
It takes place both near the coastal areas and in the broad open ocean.
The deeper cold water is highly rich in the valuable nutrients, and as they rise up they carry these nutrients and distribute them in the upper region of the ocean water body. The marine organisms are directly dependent on these nutrients, thereby helps in biological productivity.
Thus, the intense upwelling occurring in a particular area in the ocean signifies the abundance of marine species.
Hence, the correct answer is option (A).
Answer: D
Explanation: The villi increases the surface area for food absortion. Each villus has a network of thin and small blood vessels close to its surface. The surface of the villi absorbs the digested food materials.
Human Genome Project or HGP was an international and collaborative program, which aimed towards complete mapping, sequencing, and research of the human genome.
<h3 /><h3>What are the primary goals of the Human Genome Project?</h3>
- Human Genome Project was a long, extensive, and collaborative research program initiated in the year 1990 and ended in 2003.
- The aim of the project was to map and sequence the human genome to understand the genetics, hereditary, and other biological studies.
- The primary goal of the HGP was to accurately sequence the 3 billion nucleotide base pairs. The second aim was to identify the genetic sequence in the DNA, which is estimated to be 20,000 to 25,000.
Thus, the primary aim of the HGP was to sequence the 20,000 to 25,000 genes that comprise the human genome.

Answer:
Nutrition
Explanation:
<em>Nutrition generally described as the study and analysis of the components that make up foods and how these components relate to growth, reproduction, healing and overall well-being of organisms that consume such foods.</em>
<em>It studies how the various components of foods interact and combine to produce certain effects on organisms.</em>
