Answer:
by being facilitated
Explanation:
If something needs to enter the cell and could not go through the phospholipid bilayer, it could be assisted through a process known as facilitated diffusion.
Facilitated diffusion involves the passive movement of molecules that will ordinarily not pass through the phospholipid bilayer of the cell membrane through the help of the channel or carrier proteins.
If the phospholipid bilayer will not allow some molecules to pass through it as a result of a concentration gradient, the channel/carrier proteins form a special passage and the molecule is facilitated by such passage to move across the membrane.
In dogs, there is a hereditary type of deafness caused by a recessive gene. Two
heterozygous dogs mated, they both carry the gene for deafness but have normal hearing. Using the Punnett Square below, answer the following questions.
1. What are the possible genotypes? Select all that apply based on the Punnett Square above. *
DD
Dd
dd
2. What is the genotype for offspring #2?*
DD
Dd
dd
Answer:
All of the genotypes for question one are possible. for question 2, the genotype of offspring 2 is Dd.
Explanation:
The chart shows that there can be a combination of genes DD, Dd, and dd (D being the dominant trait, d the recessive). there's a one in four chance of blindness for the dog. by reading the rows and columns of the chart, you can determine which genes the dog will have.
1.Since both of the parents are heterozygous the offspring can have all three genotype possiblities: DD Dd and dd
2.The genotype of offspring is the combination of the alleles D and d:Dd
What technique did Hershey and Chase use in their experiment that led to the conclusion that DNA, not protein, was the genetic material in viruses?
Answer:
They used radioactive labeling techniques to build two different types of phage.
Explanation:
In 1952, a set of experiments were carried out by American biochemists Alfred D. Hershey (1908-1997) and Martha Chase. They prepared two separate virus samples, one contained DNA labeled with a radioactive isotope and the other contained protein labeled with a different radioactive isotope. They grew the two types of viruses separately, infected bacteria with the two sets of phages and analyzed the bacteria for radioactivity. From the results obtained, Hershey and Chase concluded that the viral genetic material was DNA and not protein, reinforcing the observations previously made by Avery.
Which cells in your body goes through mitosis the most and least?
Answer:
Somatic cells in your body goes through mitosis the most. And
Gamete cells in your body goes through mitosis the least.
Mitosis occur most in somatic cell and least occur in germ cell of the body.
What is mitosis?Mitosis is process occur both in unicellular and multicellular organisms, the division of the cell where the number of chromosomes remains the same, except in the case of germ cells where the number of chromosomes become half.
In this stage of cell cycle the nucleus of a cell is divided into two nuclei having equal amount of genetic material and produce both the daughter nuclei.
It is succeeded by cytoplasmic division after the separation of the nucleus. It is important for the growth of the cells and the replacement of worn-out cells.
In every cell division, production of two daughter cells are from the parent cell; It is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.

DNA binding proteins in prokaryotes regulate gene expression by controlling transcription
true or false
Answer:
True
Explanation:
Gene expression, which involves the transcription of DNA into mRNA and the subsequent translation of mRNA into proteins, is regulated in the cell of prokaryotes i.e. it is kept under control. This regulatory process, however, is done at the TRANSCRIPTIONAL LEVEL, in prokaryotic organisms like bacteria.
DNA binding proteins called transcription factors bind to the promoter region of a gene and either facilitates/enhance the binding of RNA polymerase or inhibits its binding. The enhancers are called ACTIVATORS while the inhibitors are called REPRESSORS.

Answer:
17. C " TAAGCTG". It would be the replication strand because A always pairs with T and C always pairs with G, so replication strands just have the opposite base as the original strand
18. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
19. Straight hair is controlled by a recessive allele because as you can see the one where is not shaded is the one that has the most. There are only 1 shaded circle or square, out of the 12 other circles or square that is not shaded. This means that it is the recessive allele because people are less prone to getting straight hair, as you can see in that diagram.

Breeders will induce mutations in organisms to increase the genetic variation in that organism’s population.
Please select the best answer from the choices provided
T
F
Answer:
The statement that indicates that breeders will induce mutations in organisms to increase genetic variation in the population of that organism is true.
Explanation:
Induced mutations can be produced by the introduction of chemical or physical agents that can alter DNA and produce genetic variation. This, when controlled, can produce physical or functional changes in a manipulated population.
Mutation induction is a technique used by breeders to increase the genetic variation of a population of plants, for example, and make their characteristics improve, such as their resistance or productivity.

Describe three interactions that red wolves might have with other living things.
Answer:
By scent-marking, body language, and a series of vocalizations, red wolves interact. These contain, along with a series of barks, growls, and yaps, the distinctive howl. The howl of the red wolf is somewhat similar to that of a coyote, but is mostly pitched deeper and lasts longer.
Red wolves communicate with one another through vocalizations, body language, and scent-marking. The unique howl may be heard in these, along with a variety of barks, growls, and yaps.
What best define red wolves interactions?Until they become accustomed to people, wolves typically avoid engaging with them.
In general, red wolves create enduring pair connections with one another. There are still more than half of red wolves in captivity. Red wolves live an average of eight to nine years in the wild.
Please make a donation to protect wolves where they belong—in the wild. Fend off the wolves. Although wolves are apprehensive of people, they can lose that fear by becoming accustomed to them.
The howl of the red wolf resembles that of the coyote in some ways, but it is often deeper and lasts longer.
Therefore, red wolves communicate by scent-marking, vocalizations, body language.

Similarities of Mitosis and Meiosis :))
Explanation:
Mitosis and meiosis have different purposes, but share common features in how they work.
Easy Answer:
-Both can divide (option 1)
-Same number of chromosomes as the original cell (option 4)
-Both have the basic 5 phases
Multiple Stages
Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division. Prophase is when the nuclear membrane degrades. Metaphase is when the chromosomes align in the middle of the cell. Anaphase is when the chromosomes are pulled apart. Lastly, telophase is when one cell splits into two separate cells.
DNA Replication
Mitosis and meiosis both involve duplication of a cell’s DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells. Before DNA can be separated between two cells, it must be duplicated and then condensed into a form that can be efficiently transported. The condensed form of DNA is called chromosomes. Chromosomes can be physically pulled apart, and make separating long strands of DNA easier for the cell because the DNA strands become like a tightly wrapped yarn ball.
