Which of the following is the function of nucleic acids?
A. Breakdown chemical compounds
B. Carry heredity information
C. Structural support
D. Short-term energy storage
Answer:
B. Carry heredity information
Explanation:
Nucleic acids are one of the four types of biological molecules in nature. The other three being: proteins, carbohydrates, lipids. Nucleic acids consists of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA).
DNA is a nucleic acid found in the NUCLEUS of eukaryotic cells or nucleoid region of prokaryotic cells where it functions to store or hold genetic information for the cell. On the other hand, RNA functions to carry the stored information in order to be expressed. Hence, according to this question, the nucleic acid functions to carry heredity information.

Consider what you know about biotic and abiotic factors in an ecosystem. What is one of the reasons that nutrients in a vegetable patch might be considered abiotic?
Answer:
Nutrients can come from dead plants that have decomposed. Available nutrients affect the carrying capacity of garden plants. Nutrients are mostly obtained from the soil.
One of the reasons that nutrients in a vegetable patch might be considered abiotic is:
The nutrients are gotten from the soil and they are decomposeAccording to the given question, we need to give one reason why the nutrients in a vegetable patch can be considered an abiotic factor.
As a result of this, we can see that the nutrients in a vegetable patch can be considered as an abiotic factor because they are already decomposed.
An abiotic factor in an ecosystem is any non living thing which has a direct (or indirect) impact on the living things in an ecosystem.

WILL RANK BRAINIEST HELP ASAP!!!
The explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.
During gene transcription, a fragment of DNA called gene is used as template to create a complementary messenger RNA (mRNA).Subsequently, this mRNA is then used as template to generate a protein by a process called translation.This mRNA is a single-stranded nucleic acid instead of a double-stranded nucleic acid (like DNA).In conclusion, the explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.

What causes the cell in living organisms to be different from one another?
The cells of different body parts are different from one another because they contain different cell organelles according to the function of that body organ.
What are the different types of cells?Typically, they achieve this without changing the DNA's sequence. An identical set of genes are present in every cell in an individual (see more on genes).
The specific genes that each type of cell “turns on” determine what proteins the cell will generate. The distinct protein composition of each type of cell enables it to carry out certain functions.
Because they create and accumulate various collections of RNA and protein molecules, the various cell types in a multicellular organism become distinct from one another.
Therefore, because each body part's cells have a unique cell organelle that is exclusive to that body organ's function, they differ from one another.

What is the variety of gene combinations that exist within a population called?
A population's genetic diversity can be quantified via genetic variation, genetic diversity is the term used to describe the genetic variation of an entire species.
What is genetic variation?Each variant of a gene is referred to as an allele, and genetic variations are the variances in DNA segments or genes across individuals.
A population's naturally occurring genetic diversity is studied by population geneticists. A population's gene pool is made up of all the genes and different alternative or allelic versions of those genes.
Some genes exist in a number of forms, all of which share the same genetic locus on a chromosome.
Therefore, genetic diversity is the variety of gene combinations that exist within a population.

equation of gaseous exchange in plants
Answer:
See the answer below
Explanation:
Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.
Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:
Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy
Or better still;
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]

9. yeah, true
10. c
Explanation:
Pro phase is the starting stage of the division where the cell division begins. Spindle fibers are broken into half and the type of division that is present in gametes is reduction division that is the meiosis. Synapsis occurs during mitosis.
What is synapsis ?It is defined as the stage in which the pairing of the homologous chromosomes take place.
Chromosomes do not line at the equator as the lining of the chromosomes at the equator occurs on the stage of mitosis where it is possible to see the V,J and L shapes of the paired chromosomes. After this stage the exchange of genetic material takes place.Chromatin do not change into chromosomes in the metaphase.
Mitosis is present only to make the duplicate copies of the cell. The identical daughter cells are made when the division of mitosis is taking place in the cell. Chromosomes are first visible in the prophase. A centromere holds two sister chromatids together.
In meiosis crossing over takes place in anaphase 1.
