Human cells have two sets of DNA in each cell. Thus, the correct option is A.
What is DNA?DNA stands for Deoxyribonucleic acid. It is considered the genetic material of most organisms. It consists of base pairs like adenine, thymine, guanine, and cytosine.
Human cells have two sets of DNA in each cell, one came from the paternal side while the other came from the maternal side.
Therefore, it is well described above.

What are lipids?Lipids have three main biological activities in the body: they are essential signaling molecules, structural elements of cell membranes, and energy storage facilities.
Triacylglycerols (commonly known as triglycerides), phospholipids, and sterols are the three primary categories of lipids. Fats are subtypes of lipids that are typically composed of glycerol and fatty acid chains.
One sort of lipid, which includes fats, is a group of molecules that don't mix well with water. Hydrophobic, nonpolar, and primarily composed of hydrocarbon chains, lipids have a tendency to be.
Therefore, the correct option is D. They are the main structural components of membranes.

Following the fusion of an egg cell and sperm cell, the resulting diploid cell divides by mitosis to create two new daughter cells. Each daughter cell contains pairs of chromosomes, with one set inherited from each parent.
Which of the following best describes the pairs of chromosomes that are present in each newly formed daughter cell?
Choose 1 answer:
A) The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes.
B) The pairs are non-homologous chromosomes that contain different sets of genes.
C) The pairs are homologous chromosomes that have identical copies of every gene.
Answer: A
i have no idea why
The pairs are homologous chromosomes that have the same set of genes, but likely different variations of those genes. The correct option is A.
What are homologous chromosomes?Among a pair of chromosomes with the very same gene sequence, loci, chromosomal size, and centromere location is referred to as a homologous chromosome.
One paternal and one maternal chromosome make up a homologous pair. In humans, the nucleus of a somatic cell contains 46 chromosomes.
Homologous chromosomes differ from sister chromatids because they are not identical and do not emanates from the same organism.
Sister chromatids are identical, side-by-side duplicates of each other that form as a result of DNA replication.
Homologous chromosomes do not pair together during mitosis. Homologous chromosomes line up end-to-end in mitosis so that when the cells divide, each daughter cell receives a sister chromatid from both members of the homologous pair.
Thus, the correct option is A.

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female
The combination of gametes that will be produced by the Alpha female is Bg, Bg, bg and bg.
According to this question, two genes coding for eye color and coat color in wolves are involved. Gray coat color (G) is dominant to black coat color (g) while brown eyes (B) are dominant to blue eyes (b). The alpha female of the pack is said to have a brown eyes and a black coat (gg) but she is heterozygous for eye color (Bb). This means that she posseses the following genotype: Bbgg. According to Mendel in his law of independent assortment, alleles of a gene will segregate into gametes independently of one another. This means that the alpha female with genotype (Bbgg) will segregate into the following combinations of gametes: Bg, Bg, bg and bg.Learn more about gamete formation at: https://brainly.com/question/11523490?referrer=searchResults

How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.
Answer:
c
Explanation:
because its the only one that would be hurting wild life.
Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.
What are the negative impacts of dams?Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.
In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.
These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.
