The spinal cord
The spinal cord part of the central nervous system is involved in this automatic response.
The spinal cord is a long, tiny tube of nervous tissue that support cells which passes from the end of the brainstem to the bottom of the spine. The central brain nervous system is made up of the spinal cord and the brain. The spinal cord is the center for coordinating many reflexes and it plays major roles in the transmission of nerve signals (messages) between the brain and the rest of the body.
b. Lipids
c. Carbohydrates
d. Protein
The Nutrients that contains the most calories per gram are lipids (or fats), with 9 calories per gram compared to 4 calories per gram in both protein and carbohydrates.
Your question asks which one of the following nutrients that contains the most calories per gram.
The answer is lipids (or fats).
When we look at calories per gram, which is a measure of energy density, lipids contain more calories per gram than protein and carbohydrates.
In fact, lipids contain 9 calories per gram, while protein and carbohydrates each contain 4 calories per gram.
Vitamins do not contribute calories, but they are essential for various bodily functions.
This is why fatty foods are considered calorie-dense, meaning they have more calories per unit mass than other nutrients.
For example, animals tend to seek lipid-rich food for their higher energy content due to the high caloric content.

The correct option is (b) Lipids.
Further Explanation:
Certain molecules or polymers are present in all the living organisms those molecules are known as biomolecules that include protein, carbohydrate, and fats. These different molecules provide a differential amount of energy to the living system.
Proteins- are the polymers that are made up of amino acids. Amino acids are linked to each other through peptide molecules.
Carbohydrate- they are the polymers that are made up of monosaccharide to further form disaccharide and polysaccharide. The bonds present between the sugar units in the carbohydrate molecules are known as the glycosidic bond.
Lipids- they contain long chains of fatty acids. It provides high energy or calorie per gram.
Vitamin- they are just the organic molecules that are required in low quantity by the organism to sustain life. It includes vitamin b, a, d, c, k, etc.

Chromosomes are inherited from the parents. One chromosome from each of 23 pairs came from each of the parents. The two chromosomes of a pair (except for the sex chromosomes) contain the same genes, but the genes have small differences. The X and Y Chromosomes determine the organism’s sex. One chromosome pair - the sex chromosomes - is unique. Typically females have two X chromosomes and males have an X and a Y. Mothers always pass an X chromosome on to their children. Whether the father passes on his X chromosome (leading to a pair of X chromosomes) or his Y chromosome (making a mixed set) determines your sex. Chromosomes get shuffled when eggs and sperm are made. Though most adult cells contain two sets of chromosomes, sperm and egg cells are different. These special cells have just one chromosome from each pair. Which chromosome they get from each pair is random, making each sperm or egg cell unique. There is also a bit of mixing before the chromosomes are sorted into individual sperm or egg cells. Chromosomes from each pair in a mother or father, respectively, make contact and exchange pieces of DNA, creating hybrid chromosomes.
Answer:
Explanation:
genes and DNA code for the production of proteins, which can cause traits to be expressed .
transforming the energy in glucose and related molecules in a chemical form that cells can use for work best describes the main purpose of the combined processes of glycolysis and cellular respiration .Thus option B is correct.
A metabolic process in which a series of steps occur to convert chemical energy (sugar) into ATP in the cell.
The first stage is glycolysis, which breaks the glucose molecule into two smaller molecules called pyruvate, and releases small amount of ATP energy and it is oxygen independent.
second stage where reorganization of pyruvate molecules and fused over again in a cycle, carbon dioxide is formed and electrons are removed.
These electrons placed in an electron transport system release ATP for the plant to use for growth and reproduction and this process is oxygen dependent.
Thus option B is correct.

bryophytes
gymnosperms
angiosperms
Answer: bryophytes
Mosses belongs to the division of Bryophytes. These are small plants that are flowerless. They typically grows in mats. They often grow in damp and shady locations. The plants exhibit simple leaves that are only one cell thick, that are attached to a stem that may be branched or unbranched and performs very little role in conduction of water and minerals.
Answer:
bryophytes
Explanation:
B.The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.
C.Both ends of the molecule have a partial negative charge, which attracts the other water molecule towards itself.
