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.
Ecological models ( physical and computer) enables the Simulation of a large scale ecology which makes it easier to identify an ecological problem and also design a solution in relation to the problem identified.
An ecological model is the simulation of the ecosystem which is used for survey, in order to identify, ecological problems, reveal the properties of the ecology, and also for the testing of scientific hypothesis. which would have been difficult to be carried out on a real ecosystem.
Ecological models can be grouped into; biodemographic, bioenergetic, and biogeochemical. and they are applicable in wildlife conservation and agriculture.
Hence physical and computer ecological models can be used to design a solution for an ecological problem by the simulation of a large scale ecology to identify and design a solution

Answer:
Fibrinogen
Explanation:
Fibrinogen is one of the proteins present in the blood plasma. It makes 7% of the plasma proteins. During the process of blood clotting, the active thrombin enzyme serves to convert soluble fibrinogen into insoluble fibrin. These insoluble threads of fibrin form the clot. Both thrombin and fibrinogen are produced in the liver. If fibrinogen is less than 4%, the process of blood clotting will be disturbed due to the production of insufficient threads of fibrin.
The answer is; A, B, D
Celular respiration break down carbon-based sources of energy and harness the energy is chemical bonds through ATPs, the energy currency of cells. Some ATP is spent in initiating the biochemical reactions, however, there is a net positive gain in the produced ATPs at the end of the reactions.
Answer: A compound that doesn't have carbon.
