Answer:
16 types of gametes
Explanation:
AaBBCCDdEeFf genotype has 6 pairs of genes. Gene B and C are in homozygous condition i.e. both the alleles are same so they will only provide one allele per pair. Rest 4 genes i.e. A, D, E and F are in heterozygous condition and will give 2 alleles per pair.
So the number of gametes = 2∧n where n is number of heterezygous pairs.
Here n=4 so 2^4= 16 types of gametes
Answer:
b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.
Explanation:
Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.
When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.
Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.
I believe the answer is the global free-market approach.
It is because on continually increasing use of earth's natural capital, and it focuses on short term economic benefits with little regard for degradation and depletion of natural capital and resulting long-term harmful environmental, health, and social consequences. Environmental world views are the ways of thinking about how the world work and beliefs that people hold about their roles in the natural world, another factor is widespread lack of understanding of how earth's life-support system works, keeps us alive, and supports economies.
