Answer:
Because of the polination characteristics of the pea plant.
Explanation:
Mendel had various reasons to use pea plants for his genetic experiments such as the observability of the pea's traits, ease of reproduction etc. but the main reason he used them is because they allowed him to have controlled mating which made the traits more controllable and therefore Mendel was sure of his observations and results. This was possible because the pea plants, during their flowering periods, are protected from alien pollinating, therefore he could control the polination process of the experiment, which was crucial in terms of accuracy and reliability of the results.
I hope this answer helps.
Together the insulin and glucagon help maintain a state is known as homeostasis in which conditions inside the body remain steady.
<h3>
What is homeostasis?</h3>
Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them.

The differentiation is based on a set of activation / inactivation of genes (parts of DNA) via complex cascades of regulation. We can not consider a differentiating cell individually. Indeed, its "expression profile" depends on its environment: cell-cell interactions, cell-matrix. It is these extra-cellular signals that will trigger the internal regulation signals. The establishment of plans for the organization of a Drosophila embryo or the development of limb buds in mice are well-known models. In these models, so-called "positional" information plays a large role: a substance present in the form of a concentration gradient in the extracellular medium will trigger or not intracellular signals depending on the dose at which the cells are exposed along this gradient.
Answer: Option D
Explanation:
Apolipoprotein B is a type of apolipoprotein that bind lipids including cholesterol and forming the main organizing protein in lipoproteins such as in the low density lipoprotein. The low density lipoprotein serves as a vehicle to transport cholesterol into the cell through the receptor mediated endocytosis process. This process allows for the movement of larger molecules from the outside of the cell into the cell. Thus apolipoprotein can bind as ligands to the LDL receptors and allow for the transport of fats into the cell..
3rd option im pretty sure. Sorry if its incorrect
