Isn't it none of the above? don't cells use mitosis?
Whales play an important role in stabilizing the aquatic food chain and reproduction of other species.
As more whales are killed the food distribution in the ocean becomes destabilized and causes changes in the food supply of many other kinds of marine life.
Whales are vital to the food chain, stabilising food flow and maintaining a healthy ocean.
As such, the rapidly decreasing whale population will have major effects on the ocean's ecosystem.
Believe it or not, whale poop also serves quite an important purpose to the ecosystem.
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).
Answer:
O by building structures on natural habitat areas
Explanation:
The diversity within an ecosystem can be compromised by building structures on natural habitat areas.
An ecosystem is part of the environment made up of living and non-living components in their natural habitats.
- Diversity entails variations in the life forms within a particular ecosystem.
- When human-induced pressure begins to impact the environment, diversity is threatened
- Nature has its balancing effect the allow for a wide range of organisms to thrive.
- When human builds structures, part of the natural habitat is lost.
The connective tissue is among the four major classes of the tissue. It is the most widely distributed and the most abundant class of the tissues. However, the type of tissue in every organ varies. Composed of cells, fibers and matrix, this type of tissue is different in different organs of the body.
The variability in it's type is provided by the difference in the degree of the order of the cells, fibers, and the matrix. This variability contributes to the diversity of this tissue.
Hence, the blank can be filled with 'diversity'.
