Answers
Macronutrients are all substances that provide energy to the metabolism for optimal functioning, nitrogen and phosphorus are required in large amounts for organisms to survive.
What are macronutrients?It refers to those elements that provide energy to the body, these are proteins, carbohydrates and lipids.
Nitrogen and phosphorus, meanwhile, allow the development of metabolic processes, prevent infections and contribute to growth.
Therefore, we can conclude that the body requires a greater amount of macronutrients than micronutrients, nitrogen and phosphorus are required in large amounts for organisms to survive.

Answers
Answer:
it Carbon dioxide and water but Carbon Dioxide was the only one here
Explanation:
The one that is a product of cellular respiration is carbon dioxide. The correct option is A.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the appearance of an inorganic electron acceptor such as oxygen to yield huge amounts of energy, which drives the bulk production of ATP.
In plants, photoautotrophic processes are used to obtain the glucose required for cellular respiration. This means that plants can use the light energy they receive from the sun to produce glucose and oxygen.
ATP is the primary product of cellular respiration; waste products include carbon dioxide and water.
All through cellular respiration, one sugar molecule is converted into 38 ATP molecules. The electron transport system actually creates 34 molecules of ATP out of a total of 38 molecules.
Thus, the correct option is A.

Explanation:
'The microorganism can be isolated and grown in a pure culture', is the only correct answer.
The statement that a microorganism can be isolated and grown in a pure culture is a part of Koch’s Postulates.
What are microorganisms?
A microorganism, or microbe is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.
The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax.
Because microorganisms include most unicellular organisms from all three domains of life they can be extremely diverse. Two of the three domains, Archaea and Bacteria, only contain microorganisms.

Answer:
A
Explanation:
Both strands of the DNA molecule act as templates
Both strands will be divided and then used to make two new DNA strands, each with half of the original

What is DNA?DNA, or deoxyribonucleic acid, is the molecule that carries the genetic material required for an organism's growth and operation. DNA has a double helix structure, which is made up of two connected strands that loop around one another to form a twisted ladder.Depending on your parents, half of your genome is inherited from your mother and half from your father. The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins. These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes. These chromosomes are composed of thousands of shorter DNA segments known as genes.To learn more about DNA refer to:

If you crossed two plants from the F2 generation, what procedure would you follow to determine the genotypes of the next generation?
Answers
Answer:
You would use a test cross to determine the next generation
Explanation:
If you crossed two plants from the F2 generation, test cross procedure you should follow to determine the genotypes of the next generation.
What is a test cross?Another important tool created by Gregor Mendel is the test cross. A test cross is a genetic experiment that involves crossing a homozygous recessive organism having a dominant phenotype with an unidentified genotype (and phenotype).
A test cross is a tool for investigating an organism's genetic makeup. The test cross was initially employed as an experimental mating test to identify the genotype's allele composition.
Therefore, to determine the genotypes, the test cross gets its name from the fact that it can tell whether a person has a homozygous dominant or heterozygous dominant trait.

Answers
Answer:

The statement that describes nuclear fission is as follows:
Starts when a neutron slams into an atom, causing the larger atom to split into two smaller atoms.Thus, the correct option for this question is D.
What is Nuclear fission?Nuclear fission may be defined as a type of nuclear reaction during which the nucleus of an atom splits into two or more smaller nuclei due to the impact of another particle with the liberation of a very large amount of energy.
Nuclear fission is a process where a heavy nucleus is bombarded through neutrons and due to this, it becomes unstable. This causes it to decompose into two or more nuclei spontaneously with equivalent size and magnitude. It involves a tremendous detachment of energy as well as the emission of two or more neutrons.
Therefore, the statement "starts when neutron slams into an atom, causing the larger atom to split into two smaller atoms" describes the process of nuclear fission. Thus, the correct option for this question is D.
