<h2>Answer:</h2><h3 /><h3>Alternative splicing is a process that occurs during gene expression and allows for the production of multiple proteins (protein isoforms) from a single gene coding. ... For example, if a pre-mRNA has four exons (A, B, C, and D), these can be spliced and translated in a number of different combinations.</h3>
Answer:
Astrocytes.
Explanation:
Astrocytes are the star shaped cells that are present in the brain and spinal cord. The exact constitution of astrocytes in the brain is not known and almost 20% to 40% astrocytes are present in brain.
The astrocytes acts as the blood brain barrier and involved in the process of brain scarring. Astrocytes also regulate ions concentration by propagating the calcium ion channels in response to the stimulus. Astrocytes also generate a response by the calcium dependent release of glutamate.
Thus, the correct answer is option (B).
This is false, as macronutrients are all made of organic components. Macronutrients are carbohydrates, fats, and proteins. The most basic unit for carbohydrates is glucose. Glucose is an organic molecule with a chemical formula of C6H12O6 which then is broken down by the body to convert it to energy (in the form of ATP). Fats or triglycerides are comprised of fatty acids and a glycerol backbone which can also be used by the body for energy or can be stored for later use. Proteins on the other hand are functional molecules wherein the basic unit for proteins is the amino acid. Proteins are exemplified because they contain nitrogen (CHON). All of which can be used as energy and has specific caloric value per gram (4 kcal for every gram of protein and carbohydrates and 9 kcal for every gram of fat).
Micronutrients are usually inorganic compounds with no caloric value. Usually these micronutrients are essential for maintaining biochemical pathways in the body. For instance, niacin and riboflavin are vitamins that are needed in the production of NAD and FAD which are important for reduction-oxidation reactions in the body (i.e. tricarboxylic acid cycle and electron transport chain).
Using antibiotics to decifer genetic code and fight the virus
Answer:
If both parents are heterozygous in a monohybrid cross, the offspring will have a phenotypic ratio of 3:1. If both are heterozygous for both traits in a dihybrid cross, the phenotypic ratio will be 9:3:3:1.
