Answer:
Nuclear receptors (NRs) are a class of proteins responsible for sensing steroid and thyroid hormones and certain other molecules. There are 48 genes in the human genome that code for the NRs. The myriad molecular pathways modulated by NRs including but not limited to inflammation, lipid metabolism, apoptosis, extracellular matrix regulation, energy metabolism, and angiogenesis.

Explanation:
Answer:
When seeds of early- and late-succession species were raised under low light conditions similar to those found in the understory of mature forest, researchers found that species with _____ seeds had _____ seedling survivorship in shade.
The correct answer for this is:
There was no relation between seed, size, and seeding survivorship.
Explanation:
Even though when in our case there was no direct relationship between speed, size, and seeding survivorship. It doesn't make it a generalization, because many factors intervene in this phenomenon. Now, light is a factor of growth, photosynthesis, and survival. However, this three-variable correlation was not found affected by the independent variable.
Answer:
Explanation:
Laboratory is a place where ideas and concepts can be tested through experiments. Biology, like any other discipline of science, is based on experimental work and therefore practical forms an integral part of learning.
Magnification by a microscope is a multiple of the X value of the lenses of the eye piece and objective. For example, a 5X eye piece and a 40X objective will magnify the image 5 × 40 = 200 times the size of the object. Similarly, when a 10X eye piece and a 40X objective are used, magnifying power would be 10 × 40 = 400X. Generally, in a compound microscope, the eye piece lenses are 10X or 15X and the objective lenses are 10X as well as 40X.
Nitrogen,<span>The atmosphere is composed of ~78% nitrogen and ~21% oxygen, with small amounts of other gases. The bulk composition of the earth by weight is mostly, iron, oxygen, silicon and magnesium, in that order, with all the other elements making up only about 5% of the earth's weight.</span>
Answer:
The correct answer is B.
Explanation:
Given there is a hybrid produced between two species Rana Ridibunda and Rana Lessonae and their offspring can not reproduce, this can mean there is "Postzygotic Isolation" between the said two species. Postzygotic Isolation is defined as "not being able to have fertile offspring" and that is the case in the example. I hope this answer helps.
