Answer:
Many human and physical factors affect population distribution and population density across the world. Physical factors that affect population density include water supply, climate, relief (shape of the land), vegetation, soils and availability of natural resources and energy.
Answer:
A. Haploid (n)
Explanation:
Conifers do not exhibit double fertilization that forms triploid (3n) endosperm in flowering plants.
Endosperm in conifers develops from the haploid cell of female gametophyte before fertilization. Since the endosperm is formed by the mitotic divisions in the haploid cell (n) of female gametophyte, it is haploid (n) in nature.
The answer is; glycolysis
This process converts glucose molecule to pyruvate. It is an oxygen-independent pathway, unlike the Krebs cycle. Glycolysis occurs in the cell cytoplasm while the Krebs cycle (aerobic pathway) occurs in the mitochondria. In the presence of oxygen, the product of glycolysis, i.e pyruvate, is fed to the Krebs cycle. If oxygen is unavailable the pyruvate is converted to lactate.
Answer:
The order of genes is- dp-cl-ap
Explanation:
The genes a be mapped on chromosome on the basis of the recombination frequency as the recombination shows that is the genes are linked or not. In genetic mapping, 1 per cent recombination frequency is considered as 1 cM or map distance.
In the given question, the three gene distance are provided on the basis of which the gene can be mapped in the following manner:
1. Take the higher value of gene distance that is 42 m.u and plot them on the line,
2. now place second-highest value on the line that is 39 m.u.
3. The gene will be arranged in the order of dp-cl-ap.
4. dp--³---cl-----------³⁹---------------------ap.
Thus, dp-cl-ap is correct.
