Answer:
A. The virus depends entirely on a host cell to reproduce
Viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.
What are the difference between single- celled and multicellular organism?The main difference between single- celled and multicellular organism is that single- cellled organisms are made up only single cell on the other hand multicellular organisms are made up of multiple cells.
Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic Cell
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.
Eukaryotic cell
Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.

In the DNA double helix, archaic pairs with thymine and cytosine pairs with
guanine.
True or false?
Answer:
False
Explanation:
'Adenine' pairs with thymine and cytosine pairs with guanine in a DNA double helix.
It is false that in the DNA double helix, archaic pairs with thymine and cytosine pairs with guanine.
What is DNA double helix?In molecular biology, the structure created by double-stranded molecules of nucleic acids like DNA is referred to as a "double helix."
A nucleic acid complex's double helical structure develops as a result of its secondary structure and plays a crucial role in establishing its tertiary structure.
One of the four bases—adenine (A), cytosine (C), guanine (G), or thymine—is joined to each sugar (T).
Adenine forms chemical bonds with thymine while cytosine forms chemical bonds with guanine to join the two strands together.
A broad head, prominent supraorbital ridges (brow ridges), and the absence of a prominent chin are characteristics of archaics that set them apart from anatomically modern humans.
Thus, the given statement is false.

Explanation:
Paleoclimatic analysis has generated a claim that there is a possible correlation between an extinction event around 29 million years ago that allowed grasslands to become abundant and the adaptive radiation of several groups of butterflies.
Which of the following proposes the best alternative hypothesis for the claim?
A- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, but there is no significant difference between speciation rate, as well as species richness with regard to butterflies, before and after 29 million years ago.
B- Climate analysis conducted by sampling pollen preserved in amber shows an increase in grass pollen 29 million years ago, which indicates there was an increase in grasslands that correlates to an increase in butterfly speciation during the same time period.
C- There is a correlation between the rapid and wide-ranging decrease in species richness of insects in general 29 million years ago and the increase in species richness and diversity among the butterfly population during the same time period.
D- Evidence of rapid speciation among butterfly species 29 million years ago is evenly distributed among all environments of that period.

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. decrease the rate of oxygen diffusion from the alveoli to the blood. increase the partial pressure of carbon dioxide in the alveoli. decrease the rate of carbon dioxide diffusion from the blood to the alveoli. have no effect on either the partial pressure or diffusion rate of gases.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.
What is atavism?
Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.

MEIOSIS:
Meiosis is a kind of division that results in the formation of four haploid daughter cells that are genetically different from one another. Meiosis occurs in a two step division process namely: meiosis I and meiosis II. Meiosis I involves division of homologous chromosomes and produces two daughter cells that are diploid (2n) while meiosis II involves the division of the sister chromatids and produces haploid (n) chromosomes. Therefore, the difference between phase I and phase II of meiosis is: Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.Learn more at: https://brainly.com/question/12327654?referrer=searchResults

Why do these sisters have different traits? Use these words in your response (protein, molecule, structure, trait, variation) describing what would determine these traits at the molecular scale.
Answer:
[Protein, Molecule, Structure, Trait, Variation]
Each offspring receives two copies or variations of each gene, one from their mother and one from their father. Each offspring can inherit a different combination of gene versions, so siblings can have different traits from each other and from their parents. The girl on the right has straight hair, whereas the girl on her left, has curlier hair. A gene code for a specific protein that's involved in a traits expression. In the structure of a cell, the proteins do much of the chemical work inside the cell, so they largely determine the traits and whose they are. Another thing to remember is genes are also made up of molecules. Thin strands twisted around each other like a spiral staircase.

The differences that occur at the molecular level or in the genes, will result in changes in the proteins which the genes code for bringing about variation in traits.
What is variation?Variation refers to the changes that occur between individuals of the same species due to environmental or genetic factors.
The basis for variation is differences that occur at the molecular level.
The genes are regions of the DNA which code for a particular trait.
The DNA is composed of chains of polynucleotide molecules.
When differences occur at the molecular level or in the genes, the proteins which the genes code for will have differences in structure.
Thus, the individuals will show variation as in the case of the two sisters who show variation in height and hair structure.
