The correct answer is chromatin. Chromatin<span> describes macromolecules in cells composed on </span>DNA<span>, </span>protein <span>and </span>RNA. Chromatin has various functions in cells. The main functions are<span> to package DNA into a compact shape, to allow mitosis by reinforcing the DNA macromolecule,</span><span> to prevent </span>DNA damage<span>, and to control </span>gene expression<span> and DNA replication. </span>
Answer:
Here are the options to complete the question
A. plants
B. animals
C. inorganic compounds
D. genetic engineering
The CORRECT ANSWER IS D.
D. genetic engineering
Explanation:
Drugs can be produced or obtained by extracting the essential component needed from a plant source, animal source and inorganic compounds.
Genetic engineering is a synthetic source of drug production, needed to solve or make ready drugs with the aid of advanced technology/process.
Answer:
There are advantages and disadvantages of sexual reproduction, compared to asexual reproduction. The main issues are: Advantages: More variation assists with survival. It increases the chance that at least some offspring of a parent survive.
Krebs cycle the sequence of
reactions by which most living cells generate energy during the process of
aerobic respiration. It takes place in the mitochondria, consuming oxygen,
producing carbon dioxide and water as waste products, and converting ADP to
energy-rich ATP.
a. FAD
b . CO2
c. ATP

<span>Sympathetic dominance---
Increase in muscle mass----- Raise
Decreased in insulin----- </span>Lower the tmr<span>
Decrease in TSH ---- Lower the tmr
Increase in adrenal cortex function ------</span>raising the tmr<span>
Increase in thyroxine ---- </span>raising the tmr<span>
Training for a marathon -----raising the tmr
Malabsorption of nutrients-------- </span>Lower the tmr<span>
Decrease in adrenal medulla function ------ </span>Lower the tmr<span>
Epinephrine secretion------- </span>raising the tmr
The total metabolic rate is the total energy used by the body each day. Physical activity such as Training for a marathon require more energy and leads to increasing the tmr. Whereas, malabsorption of nutrients lowering the tmr because less food is being supplied, and therefore less energy production.
