The correct choice is (B) Herpesviridae virus. Herpesviridae is a big or we can say large family of some DNA viruses that may cause infections and may have certain diseases in animals, as well as including humans.
Prevention: A vaccine was recently approved in the United States to prevent infection with the varicella-zoster virus. Vaccines against herpes simplex virus 2 and cytomegalovirus have been extensively evaluated in field trials. Passive immunization with immunoglobulin or hyperimmune globulin is used to prevent infection or as an adjunct to antiviral therapy.
Process: Infections with herpes simplex viruses 1 and 2 and varicella-zoster virus are currently the most treatable. Acyclovir, valacyclovir, and famciclovir are all approved treatments. Ganciclovir is used to treat cytomegalovirus retinitis. The B virus appears to respond to one of these drugs. There is still no cure for Epstein-Barr virus or human herpesvirus 6, 7, or 8 infections.

If pacific field male crickets in hawaii attract females by rubbing their wings together to sing, why is it that in some places up to 90% of the males no longer sing? how could this have evolved?.
The reason why 90% of male crickets no longer sing is Convergent evolution.
What is convergent evolution?It is the independently occurring evolution of traits that are shared by species across historical eras. Analogous structures with similar functions or forms are created as a result of this evolution. They are not present in those units' most recent shared ancestor, though.
Despite the resemblance of the structures, homology is not reflected. Similarity can exist at the phenotypic level, where lineages exhibit identical outward traits yet have different implicit DNA sequences. This kind of evolution occurs when species occupy comparable ecological niches, accommodate similarly, and respond similarly to selective pressures. The "analogous structures" that result from convergent evolution. In contrast, homologous structures are understood to have a single origin.

Convergent evolution explains why 90% of male crickets no longer sing.
Why did Hawaiian island crickets develop to lose the sound that males sing to entice females?On two Hawaiian islands, crickets have acquired the incapacity to sing in order to conceal themselves from dangerous flies. Males first came on Kauai and Oahu ten years ago, two years apart. Their wings, which they usually rubbed together to chirp and attract females, were altered.
What led to the existence of crickets with different wing ridges?Additional study has validated the scientists' hypotheses that a mutation to a single gene on the X chromosome of crickets results in the quiet wing feature. This discovery contributes to the understanding of how the mutation became so prevalent in fewer than 20 generations, or the evolutionary equivalent of a blink of an eye.

mendel found that yellow pea pod color (g) was dominant to green pea pod color (g). for each of the crosses below, what percentage of offspring are expected to be yellow?
GG x GG = 100% because both parents have dominant homozygous allele G.
Gg x Gg= 75% because both the parent are heterozygous. The result of yellow offspring is GG:Gg:Gg:gg.
gg x gg = 0% because both the parent are homozygous recessive allele g after cross only green offspring would be seen.
Why is Mendel credited with founding genetics?Through his research on pea plants, Gregor Mendel discovered the fundamental ideas of inheritance. He came to the conclusion that each pair of genes is inherited separately from each parent.
The first rule of inheritance is the dominance principle. Only the dominant traits in the phenotype will be passed down to hybrid offspring, according to the law. Recessive traits are those alleles that prevent the occurrence of a trait, whereas dominant traits are those alleles that cause the occurrence of a trait.

The blood cells and neurons are wholly separate populations, and the two cell types are not interdependent in any way.
The Correct Answer is : the neuron expresses some mRNAs that the white blood cell does not.
Do white blood cells have RNA?Protein can be produced by white cells that have a nucleus and can create ribonucleic acid (RNA). White blood cells are highly differentiated for their particular functions, so they do not divide into new cells in the bloodstream (mitosis), yet some still have this ability.Leukocytes, thrombocytes, and erythrocytes make up human blood. When determining the amount of nucleic acid in human blood, leukocytes—the only cells with a nucleus—are crucial. While erythrocytes and thrombocytes do contain a small quantity of RNA, they lack a cell nucleus.Here, we report the presence of standard bands for the eukaryotic RNAs 28S and 18S in human RBCs.

When the population is 3000 organisms, the slope will be an inclined graph and when the population is 1000 organisms the graph will be a parabola in case of exponential growth.
Exponential growth is the growth when organisms or microorganisms grow in a constant number in interval of time. Exponential growth is also known as log phase growth.
The cells during exponential growth phase are at their healthiest state and are thus used for biochemical and physiological studies. During exponential growth, the cells divided at their maximal rate given the genetic potential, and the environmental conditions.
Mathematically, exponential growth can be explained as the population density is equal to the initial growth added with time of the generation.

Explanation:
What is mitosis easy definition?
A eukaryotic cell's nucleus divides in two during the process of mitosis, which is followed by the division of the parent cell into two daughter cells.
What are the feature of Mitosis?Two daughter cells are created from the parent cell during each round of cell division. As a result of the identical chromosome number in the parent and daughter cells, the cell is sometimes referred to as equational cell division. In plants, the process of mitosis promotes the growth of the plant's vegetative parts, such as the root and stem tips. In this process, segregation and combination do not take place.

What is cell division?Cell division is a crucial mechanism in unicellular organisms that helps a unicellular creature change into a new organism. The process of cell division assists multicellular animals in maintaining a balance between the DNA and RNA contents, as well as the nuclear and cytoplasmic contents of the cell. There are five of these phases: prophase, prometaphase, metaphase, anaphase, and telophase. As the final physical cell division after telophase, cytokinesis is frequently regarded as the sixth stage of mitosis. Cell division is the process of reproduction in unicellular organisms; in multicellular creatures, it is the process of tissue growth and maintenance .Walther Flemming was the first to depict various phases of the cell cycle leading to cell division in 1882 after developing techniques to dye cells that revealed intracellular features.
The process of cell division that produces sperm and egg cells is known as meiosis. A crucial aspect of life is mitosis.
A cell goes through Interphase before cell division, a period during which the cell expands and duplicates its DNA in preparation for cell division. The eukaryotic cell cycle's longest phase is this one.

Large aquatic creatures called Florida manatees are native to the state of Florida. Manatees can grow to be over 13 feet long and weigh more than 3,500 pounds, but they are normally 9 to 10 feet long from snout to tail and weigh about 1,000 pounds.

What part of the cell cycle has been disrupted to allow for the formation of cancer cells?.
The formation of cancer cells occurs in the interphase cell cycle which is disrupted, precisely when DNA synthesis is in the S phase.
How does the cell cycle affect cancer?In many cancer cells, the number of chromosomes changes so that there are either too many or too few chromosomes in the cell. These cells are said to be aneuploid. Errors can occur during DNA replication resulting in mutations and possible development of cancer.
Cancer is the result of uncontrolled cell division caused by damage to the mechanism that regulates the cell cycle. Loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Incorrect instructions cause the protein to not work as it should.
