Answer:
O d.) minerals
Explanation:
Plants have small holes called stomata on the underside of leaves. Stomata are opened to draw up water from the leaves and allow carbon dioxide in so that the process of photosynthesis can occur. During the process, some water is lost through the open stomata.
Based on this information, which stimulus is most likely to cause the stomata to close?
A. Water volume increasing in the soil
B. Water volume decreasing in the soil
C. Carbon dioxide concentration increasing in the atmosphere
D. Carbon dioxide concentration decreasing in the atmosphere
Answer:
D. Carbon dioxide concentration decreasing in the atmosphere
Explanation:
Since the stomata are opened for the plant to draw the water from the leaves A and B can't be the answer since they rely on needing water from the soil.
Stomata open to also draw carbon dioxide from the atmosphere in order for the process of photosynthesis to occur. This means that they open when there is a high concentration of carbon dioxide in the atmosphere and close when that concentration becomes lower.

Using the words: Chromosome, Genes, Dna, and nucleus; describe how genetic information is stored in cells. Make sure your answers are as clear and detailed as possible. *
Answer:
Genes are contained in chromosomes, which are in the cell nucleus.
A chromosome contains hundreds to thousands of genes.
Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes.
A trait is any gene-determined characteristic and is often determined by more than one gene.
Some traits are caused by mutated genes that are inherited or that are the result of a new gene mutation.
Proteins are probably the most important class of material in the body. Proteins are not just building blocks for muscles, connective tissues, skin, and other structures. They also are needed to make enzymes. Enzymes are complex proteins that control and carry out nearly all chemical processes and reactions within the body. The body produces thousands of different enzymes. Thus, the entire structure and function of the body is governed by the types and amounts of proteins the body synthesizes. Protein synthesis is controlled by genes, which are contained on chromosomes.
The genotype (or genome) is a person’s unique combination of genes or genetic makeup. Thus, the genotype is a complete set of instructions on how that person’s body synthesizes proteins and thus how that body is supposed to be built and function.
The phenotype is the actual structure and function of a person’s body. The phenotype is how the genotype manifests in a person—not all the instructions in the genotype may be carried out (or expressed). Whether and how a gene is expressed is determined not only by the genotype but also by the environment (including illnesses and diet) and other factors, some of which are unknown.
A karyotype is a picture of the full set of chromosomes in a person’s cells.
Genes
Humans have about 20,000 to 23,000 genes.
DNA
Genes consist of deoxyribonucleic acid (DNA). DNA contains the code, or blueprint, used to synthesize a protein. Genes vary in size, depending on the sizes of the proteins for which they code. Each DNA molecule is a long double helix that resembles a spiral staircase containing millions of steps. The steps of the staircase consist of pairs of four types of molecules called bases (nucleotides). In each step, the base adenine (A) is paired with the base thymine (T), or the base guanine (G) is paired with the base cytosine (C). Each extremely long DNA molecule is coiled up inside one of the chromosomes.

A theme in biology is how structure is related to function. Discuss how the structures of the different chambers and vessels of the heart relate to their functions. Answer should consist of 3-5 sentences, citing specific chambers of the heart to their function and why.
Answer: Different chambers of the heart perform different functions.
Explanation:
The human heart has four chambers the two atria as well as two ventricles. The function of the lower chambers of the heart is to pump out blood. The atria or upper chambers receive blood. The right atrium obtains blood from the superior vena cava then the blood moves towards the right ventricle where the deoxygenated blood is pumped out to the lungs. From the left ventricles the blood is pumped to all the parts of the body.
The heart is the major and the most important organ of the circulatory system that is responsible for transporting the oxygenated blood to the organs and deoxygenated blood from the organs.
The organ has four sections including the atrium and the ventricles. Different functions of various chambers can be explained as:
The upper right compartment is called the atrium and accepts the blood through veins and transports them to the right ventricle.The lower right compartment is called the right ventricle that receives blood from the atrium and sends it to the lungs for supplementing it with the oxygen molecules.The upper left compartment is called the left atrium and gets loaded with oxygenated blood from the lungs and transports it to the left ventricle.The lower left compartment is called the left ventricle that receives the oxygenated blood from the upper compartment and pumps it to all the body organs.Therefore, different chambers of the heart perform various functions.

These classifications are based on commonalities or shared traits among organisms. Cell type, nutrition uptake, and reproduction are a few of the aspects that are taken into account when placing an organism. Prokaryotic and eukaryotic cells are the two primary types of cells.
Photosynthesis, absorption, and ingestion are typical methods of nutrient acquisition. Asexual and sexual reproduction are both types of reproduction.

I need help in question 11. Why is genetic diversity reduced?
Answer:
The genetic diversity present in a population that is going for extinct, is lost. All these factors mean that even though the actual population size might be very large, the effective population size and therefore the amount of genetic diversity inside a colony is dramatically reduced in relation to the solitary species.
