cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.
Explanation:
The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.
The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
Answer:
B. New predators move into the ecosystem.
Explanation:
A, C, and D are all abiotic (nonliving) factors that could limit a community in an ecosystem.
Not sure if you still need this answer but i am pretty sure its the third option.
The answers are: Timber industry, paper industry, furniture industry.
These three industries depend on the trees so that they are able to make products. The timber industry uses the chopped trees, the paper industry uses the cellulose from the trees as it's basis for production, and the furniture industry makes it's products from certain types of tree. So stricter rules would mean big economic blows for this industries.
One of the reason is : An increased body size and robustness. They have long spatial/temporal range
, they were the first hominin to leave Africa, they have modern human body proportions
, they were the first to have a protruding human nose
and they actively were hunting.
