Answer:
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.
The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)
Answer:
Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins).
Explanation:
Capillaries, the littlest and generally various of the veins, structure the association between the vessels that divert blood from the heart (supply routes) and the vessels that return blood to the heart (veins). The essential capacity of capillaries is the trading of materials between the blood and tissue cells.
Blood vessels a cylindrical organization all through the body that permits blood to spill out of the heart to each body cell and afterward back to the heart. The three kinds of veins are corridors, vessels, and veins. Each vein comprises of a layered divider encompassing a focal blood-containing space, or lumen.
Answer:
The paraphrase consists in saying with simpler words and with less technical words those obtained from a text. In this way, it facilitates its understanding, because the original information extracted is expressed in a simpler way.
The correct way to paraphrase is 2. Every organism must acquire and use energy to build new structures, repair old ones, and reproduce
Explanation:
That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation
