Answer: 6
Explanation:
This is because the Met and Trp are coded by one codon, Cys is coded by two different codons, and Stop is encoded by three different codons. Therefor, 2x3=6.

Biology cell division
What are the answers to this chart
The cell spends most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.
What is the time spent in the cell cycle?
The cell enters the cell cycle, and the first stage is the G1 phase, where the cell grows and spends a lot of time nearly 11 hours and then the cell enters the S phase. In the S phase, the DNA replicates and spends nearly 7 hours, and then in the G2 phase, 3 to 4 hours are spent by the cell, with the remaining 1 to 2 hours spent in the M phase, also called the mitosis or division phase.
Hence, cells spend most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.

Without land regulations to protect rainforests, and continues to be destroyed using slash and burn methods Which environmental impact of rainforest deforestation makes rainforest species less resilient to
change?
Increased fire and drought
Increased pollution
Displaced inbes
Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.

Explanation:
Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol
In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.
Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.
Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.
In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

Which of the following is NOT part of the non-specific immune response?
A. Inflammation
B. Phagocytosis
C. Antibodies
D. Interferons
D. Interferons are not a part of the non-specific immune response.
What is the function of interferons?Interferons were first described as an antiviral thing that interferes with viral replication in mammalian cells (10). they're secreted from inflamed cells and spark off an innate immune reaction that promotes now not best cytokine production but additionally herbal killer mobile features and antigen presentation.
Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.
Interferons are a circle of relatives of clearly-happening proteins which are made and secreted with the aid of cells of the immune gadget (an example, white blood cells, natural killer cells, fibroblasts, and epithelial cells).

what molecule makes instructions for proteins and is located inside a eukaryotic nucleus
Answer:
DNA stores that info
Explanation:
In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).
The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.
The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.
The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.
During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.
The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

What is Stomach?
The J-shaped organ that digests food is the stomach. It generates acids and enzymes, which are molecules that cause chemical reactions (digestive juices).
Food is broken down by this mixture of enzymes and digestive juices so that it may move to our small intestine.
A portion of the gastrointestinal (GI) tract includes your stomach. Your mouth is the beginning of the GI tract, which is a long tube. The stool (poop) exits your body through your anus. A crucial component of your digestive system is the GI tract.
