cholesterol is synthesized by all animal cells and is an essential structural component of animal cell's membrane cholesterol is the most common steroid and mainly synthesized in the liver cholesterol also serves as a processor for several important biological compounds including all except insulin ,vitamin D, bile salts , testosterone.
Answer:
Aug 11, 2017 — Vitamin D3 is produced in the skin from 7-dehydrocholesterol by UV irradiation, 1,25(OH)2D reduces 1,25(OH)2D levels in cells primarily by Animals null for calbindin 9k (the major calbindin in mammalian abnormal vitamin D and/or calcium metabolism in some but not all of these patients (24-26). Cholesterol, a waxy substance that is present in blood plasma and in all animal tissues. it is a primary component of the membrane that surrounds each cell, and it is synthesizes bile acids, steroid hormones, and vitamin D.

Explanation:
Search Results
Featured snippet from the web
An ATP molecule consists of three parts. One part is a double ring of carbon and nitrogen atoms called adenine. Attached to the adenine molecule is a small five-carbon carbohydrate called ribose. Attached to the ribose molecule are three phosphate units linked together by covalent bonds.

Examples of ovoviviparous animal
Answer:
sharks, rays, snakes, fishes, and insects
Explanation:
These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.
Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).

What are three methods for detecting radioactively labeled DNA in an experiment?
Answer:
Limitations. detect low abundance DNA binding proteins from lysates. test binding site mutations using many probe configurations with the same lysate. test binding affinity through DNA probe mutational analysis. non-radioactive EMSA possible using biotinylated or fluorescently labeled DNA probes.
Explanation:
Answer:
Proteins interact with DNA through electrostatic interactions (salt bridges), dipolar interactions (hydrogen bonding, H-bonds), entropic effects (hydrophobic interactions) and dispersion forces (base stacking). These forces contribute in varying degrees to proteins binding in a sequence-specific or non–sequence-specific manner.
Explanation:
Which statement best describes what happens during translation?
Answer:
B
Explanation:
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
During translation, the ribosome reads the mRNA and uses the information to assemble a protein.
Translation is the second step of protein synthesis. It takes place in the ribosome, a complex structure made up of proteins and RNA. The ribosome reads the mRNA, a molecule that contains the genetic information for a protein. The mRNA is translated into a protein by a process called codon-anticodon pairing.
Codons are three-base sequences in mRNA that code for specific amino acids. Anticodons are complementary sequences in tRNA molecules that bind to specific codons. When the ribosome encounters a codon in the mRNA, it brings in the corresponding tRNA molecule. The tRNA molecule carries the amino acid that corresponds to the codon.
The amino acid is then added to the growing polypeptide chain. The ribosome continues to move down the mRNA, reading codons and adding amino acids until the entire protein is synthesized.

PLEASE HELP!!!? Are humans an invasive species? Why or why not. GIVE TWO PIECES OF EVIDENCE TO SUPPORT YOUR OPINION.
Answer:
I think yes, humans are an invasive species.
Explantation:
I think humans are an invasive species because they are everywhere, and very few places in the world do not have humans. Humans are in control of the planet because of their number. Humans are not going to be extinct ever. They are always going to be here on earth. If somebody finds new land, they make a base/camp and send other people to live there and to populate it. Like in North america, settlers came and sent men to live there. They hunted animals and set up homes. Then, more and more people came and soon all that is left is a over populated land with citys and cars and humans everywhere.

Explanation:
Density describes how much mass is contained in a certain volume. Knowing how far apart molecules are in each state, which best ranks solids, liquids, and gasses from least dense to most dense?
Gasses are denser than liquids.
Liquids are denser than solids.
Gasses are less dense than solids.
Solids are less dense than liquids.
Solids have a high density because the particles are very close together, a liquid mass is slightly less dense, and a gas mass has a very low density with the particles much further apart.
What Is a Density?The measure of how densely a material is packed together is called density. As the mass per unit volume, it has that definition. Density Formula: D or Density Symbol: D ρ = m/V where the object's mass (m), its volume (V), and its density () are all given.
Generally, gases are less dense than liquids, while liquids are less dense than solids. This is due to the fact that solids have tightly packed particles, liquids have materials in which particles can slide around, and gases have free-moving particles.
Therefore, Gasses are less dense than solids because particles are far away from each other in gas masses.
