Answer:
bird, mouse and grasshopper compete for grains
Answer:
Astrocytes
Explanation:
Astrocytes are the most abundant cells in the central nervous system that twine around nerve cells supporting the brain and spinal cord. They perform many functions; such as providing the nuerons with nutrients, control the blood brain barrrier and blood flow. Astrocytes are basically responsible for maintaining the central nervous system homeostasis.
Answer:
There are several answers to this question: The appearance of a novel phenotype resulting from a substitution of a single base pair might be due to:___. These possibilities are:
1. A change in the sequence of amino acids. It must be remembered that proteins are the ones that carry out the instructions present in genes, therefore, a change in the sequence may show also a change in a base pair, and a change in what is expressed phenotypically.
2. Change in the amount of protein that is transcribed. Again proteins are the ones that carry out the instructions from genetic material. A change in DNA will show in how not just amino acids will be arranged, but also the structure, and amount of protein transcribed, and also the types. This will alter the phenotypical expression.
3. Change in the developmental time and/or location at which a gene is expressed. Time and also the placement of the base pairs in the genetic sequence can alter how these are expressed when they are translated into RNA.
4. Alteration in a gene that codes for a non-translated RNA. It is RNA the one that will transfer information from genes in DNA and the final product, which are proteins. However, when DNA has a change in the genes that will be translated into RNA, the process may not be carried out, and if RNA is not produced, then neither will proteins. The absence of a specific sequence in RNA will also affect the production of protein and thus a phenotypical expression may, or may not, happen.
Glucose turns into ATP or ENERGY during the process of cellular respiration ..
<span>The glucose is broken down into 2 molecules of pyruvate, which are two smaller molecules. A net yeild of 2 ATP and 2 NADH result. Each pyruvate is connected to a coenzyme. The resulting molecule is called Acetyl CoA. That reaction also gives off 2 molecules of C02. The Acetyl CoA enters the Krebs Cycle, from which (through a series of steps), 2 more ATP, 6 NADH, 2 FADH2, and 6 CO2 are formed. The 6 NADH and FADH2 (which are coenzymes) move on to the electron transfer chain. Here, they give up their H+ and electrons to the chain. The electrons reduced the proteins on the chain, allowing H+ from outside the cell to be brought in. Bringing this H+ into the cell builds up the concentration. When the concentration gets high enough, the H+ wants to go back out of the cell. The only way to do this is through the ATP synthase. When is passes through this, the synthase combines an ADP with an inorganic phosphate, forming ATP. The typical yeild is 32 ATP from this, giving a total of 36 when you add in the ATP from glycolysis and the Krebs cycle.</span>
