Answer: D- Parasitism
Explanation: Parasitism is an intimate and long-term impact or interaction that a couple of organisms living in the same habitat have on themselves between two distinct living beings, where one organism lives on another living being which gives it food, eater and shelter at the expense of the other organism.
The organism that lives in the host organism causes it some damage and gives no benefits at all. Also, the parasites are usually insignificant in size when compared to the organisms they live and feed on so they are able to survive in a large category of environmental situations. In this case, the dwarf mistletoes are the parasites while the trees are the hosts.
The repressor protein is coded by the i gene.
<h3>What is the function of the repressor protein in lac operon?</h3>
A protein known as a repressor prevents one or more genes from being expressed. The i gene codes for the repressor protein. The repressor protein inhibits messenger RNA synthesis by attaching to the promoter region of the gene(s). For the control of gene expression in cells, repressor proteins are crucial.
Repressors and activators of gene expression in bacteria are different from one another. However, depending on how a DNA binding protein interacts with other proteins in the cell or in other biological contexts, higher eukaryotic cells can use it as either an activator or a repressor of gene expression. As repressors, additional components like non-coding RNA may also be present.

Answer:
A
Explanation:
the mother gives half through the egg and the father gives half through the sperm
Answer:
The three seabed habitats: vents and seeps, trenches and seamounts. The phytoplankton develops in the area exposed to the sunlight to take the elements dissolved in the sea water, including carbon dioxide, to create new cells and are responsible for about half of the inhabitants of the planet of the photosynthesis and production of oxygen. It is found mainly in the surface and lands on the seafloor as dead cells, still carrying the carbon dioxide, while maintaining the balance of oxygen/carbon dioxide in the ecosystem.
False,
In order to start labor, estrogen increases and progesterone decreases.
Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.
Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.
