Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.
Answer:
scientist has estimated that over 8.7million species in the world of plants and animals in existence, though as few as 6.5million on land and 2.2million in the ocean
Answer:In most people, that protein is fully functional and results in blood cells that have a round shape and can bind with oxygen efficiently. What would happen if one small change occurs? The change in the sequence of HbS causes the blood cells to be shaped like sausages, rather than round
Explanation:
Answer:
Explanation:
Photosynthesis use carbon dioxide and water to assemble carbohydrate molecules and release oxygen into the air easy
Answer:
Metabolism refers to chemical reactions that occur within the cells of living organisms -that involve the interaction of substrates, co-factors and enzymes to obtain a product- while homeostasis refers to the internal balance within the body.
Explanation:
<u>Metabolism</u> involves a series of processes that occur in order to obtain a result or product necessary for life. Exist chemical reactions that are part of various metabolic pathways, where chemical substances are transformed into others through the intervention of specific substrates and enzymes. In metabolism reactions can be
:
- Anabolic, when necessary molecules are constructed or synthesized, such as the biosynthesis of proteins from amino acids
- Catabolic, when a substrate is broken down to obtain a product, such as glucose to produce energy (ATP)
.
<u>
</u><u>Homeostasis</u><u> </u>is the maintenance of the proportion of elements for the body to function properly. It is the equivalent of internal balance, which makes use of internal regulation mechanisms.
<em>
A correct functioning of the metabolic reactions guarantees an adequate homeostasis, and the balance that is required for the organism to function properly, implies a regulation of the metabolic processes that occur.</em>
