Due to the fact that two gametes (one from each parent) unite during fertilization to form a diploid zygote, gametes must be haploid, meaning they contain half as many chromosomes as somatic cells of an organism. Therefore, the correct option is A.
When gametes fuse, a diploid cell with a full set of chromosomes is produced, which combines their haploid sets of chromosomes. After cell division and growth, this diploid zygote will form a new human with a full complement of chromosomes in each cell. To preserve proper ploidy during fertilization and subsequent development, gametes must be haploid.
Therefore, the correct option is A.

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.

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.

PLEASE I WILL MARK AND 5 STARS < THANKS
Answer:
The correct answer is heterozygous.
Explanation:
The pea pods are heterozygous for pod color (Gg).
"G" is the dominant gamete and "g" is non-dominant. This explains why the pod in the fourth square is yellow because there is no "G" gamete, which would dominate the "g" gamete and make the pod green.

3. Climate change has been a topic repeatedly mentioned in our study of Marine Science.
How does Jackson express the impact that climate change has on corals? Based on how
he uses it, what do you infer the word symbiosis to mean?
Answer:
Climate change lead to the destruction of corals due a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
Symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.
Note: The study material was not provided.
Explanation:
Greenhouse gas emissions from human activities have led to an increase in global surface temperature. This has resulted in a warming of the oceans, increase in ocean acidity as gases such as carbon dioxide are absorbed into the oceans, rise in sea level due to melting glaciers and increase in precipitation, changes in storm patterns, etc.
The warming of the oceans poses a great threat to life and activities in the ocean. Coral reefs especially are affected by a warming of the ocean in the following ways:
mass coral bleaching- with increase in ocean temperature, corals remove the algae living in association with them that are responsible for their colour, thereby turning corals white. With prolonged bleaching periods, the corals eventually eventually die .Sea level rise: with rise in sea level comes a likelihood of increase in flow of sediments into the sea. This sediments when deposited on corals found near land suffocates and kill the corals.Changes in storm patterns: stronger and more frequent storms can lead to a destruction of coral reefs. Increase in the acidity of oceans results in death of corals.Corals and algae exist in a symbiotic (mutualistic) relationship in coral reefs. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.
Therefore, symbiosis is a close relationship between two dissimilar organisms which usually results in benefits to one or both organisms.

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.
