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.

the transport a very large molecules such as proteins
Answer:
Very large molecules such as proteins are too big to move through the cell membrane which is said to be impermeable to them. The type of transport proteins present in a cell membrane determines which substances the membrane is permeable to. CO2 molecules pass directly through phospholipids. Glucose molecules travel through the proteins.

thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?
The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.
The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).
The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.
The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

how does a single genome code for so many types of tissues
Answer:
The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
The genome, which is the second layer, regulates gene access, allowing each cell type to activate its own unique genes while shutting off the majority of the others.
What is genome?The complete set of DNA instructions present in a cell is known as the genome. The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria.
Everything a person needs to grow and operate is encoded in their genome. The DNA sequence in a cell's genome contains the instructions needed to create tens of thousands of different protein and RNA molecules.
Thus, in multicellular organisms, distinct cell types develop because diverse sets of genes are expressed, even though a cell normally expresses just a portion of its genes.
