The chickenpox virus can remain latent in host cells by integrating its DNA into the host cell genome. This virus uses the ______ cycle as its main life cycle pathway.
The chickenpox virus can remain latent in host cells by integrating its DNA into the host cell genome. This virus uses the genoma replication cycle as its main life cycle pathway.
How does the virus replication process take place?Viral replication refers to the process by which a virus reproduces within a living organism. This usually involves turning infected cells into virus factories, which make copies of the virus's genetic code and expel them to spread into the host's body.
Upon replication, viruses produce new copies of themselves within infected cells.

What explains how the parents in a family both have the same eye color, but some of their children have a different eye color? Assume for this example that eye color is determined by a single gene.
A. One parent is homozygous dominant, and the other heterozygous for a gene that controls eye color allowing some of the children to express a different trait.
B. The parents are both homozygous dominant for a gene that controls eye color allowing some of the children to get two recessive alleles.
C.One parent is homozygous dominant, and the other homozygous recessive for a gene that controls eye color allowing some of the children to express a different trait.
D. The parents are both heterozygous for a gene that controls eye color allowing some of the children to get two recessive alleles.
The correct option is D. The parents are both heter0zyg0us for a gene that controls eye color allowing some of the children to get two recessive alleles.
What is complete dominance?When the dominant allele completely masks the recessive allele, we talk about complete dominance.
This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele.
In the exposed example, let us assume that the alleles that code for eye color are the followings,
E is the dominant allele and codes for the dominant colore is the recessive allele and codes for the recessive colorIf at least one parent is h0m0zyg0us dominant for the trait, EE, the whole progeny will express the dominant trait because all of them will carry at least one dominant allele.
If both parents are heter0zyg0us Ee, some children will express the dominant trait and some other the recessive trait. This is because some of the children receive at least one dominant allele and some others only receive recessive alleles.
Cross:
Parentals) Ee x Ee
Gametes) E e E e
Punnett square) E e
E EE Ee
e Ee ee
F1) Genotype
1/4 = 25% of the progeny is expected to be h0m0zyg0us dominant EE
1/2 = 50% of the progeny is expected to be heter0zyg0us Ee
1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive ee
Phenotype
3/4 = 25% of the progeny is expected to have the dominant eye color
1/4 = 25% of the progeny is expected to have the recessive eye color
The correct option is D. The parents are both heterozygous for a gene that controls eye color allowing some of the children to get two recessive alleles.

What process adds carbon dioxide to the air?
nitrogen cycle
O water cycle
respiration
Ophotosynthesis
Answer:
cellular respiration...that's breathing out of humans
and through human activities like burning of fossil fuels...
The respiration process adds carbon dioxide to the air. Therefore, option "C" is correct.
What is respiration?A metabolic process known as respiration involves an organism's living cells taking in oxygen and releasing carbon dioxide from the oxidation of complex organic substances to obtain energy (ATP). High-impact breath happens in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The synthetic condition is C6H12O6 + 6O2 → 6CO2 + 6H2O.
There are two types of respiration that occur in nature that is aerobic respiration and anaerobic respiration. Aerobic respiration involves the use of oxygen for oxidation and later oxygen is not used.
Therefore, respiration is the cellular process that happens in all organisms.

The organization of a organism from smallest to largest is Cell, tissue, organ, organ system, organism
True
False
The cellular organization from smallest to largest is cells, tissues, organ, organ system and organism. Hence, the given order is true.
What is cellular organization ?Cellular organization refers to the hierarchical arrangement of cells in living organisms. All living organisms are composed of one or more cells, and the way in which cells are organized within an organism is critical to its overall function and survival.
At the smallest level, cells are organized into organelles, which are specialized structures within the cell that perform specific functions. For example, mitochondria are organelles that produce energy for the cell.
Cells are then organized into tissues, which are groups of cells that work together to perform a specific function. Examples of tissues include muscle tissue, which is responsible for movement, and nerve tissue, which is responsible for transmitting signals throughout the body.
Tissues are then organized into organs, which are structures that are made up of two or more different tissues and perform a specific function. For example, the heart is an organ that is made up of muscle tissue and nerve tissue and is responsible for pumping blood throughout the body.
Finally, organs are organized into organ systems, which are groups of organs that work together to perform a specific function. For example, the circulatory system is an organ system that includes the heart, blood vessels, and blood and is responsible for transporting oxygen and nutrients throughout the body.

A new predator is introduced to an aquatic ecosystem. In a population of fish that live there, very small fish are more easily able to hide from the predators, and very large fish cannot be easily eaten by predators. What type of natural selection is acting on the population, and what will be the expected result?
A.Stabilizing selection: Since both extremes are selected against, the fish population will remain about the same.
B.Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, small and large fish will be common.
C.Stabilizing selection: Over time the fish population will change. Medium-sized fish will become rare, small and large fish will be common.
D.Disruptive selection: Since both extremes are selected against, the fish population will remain about the same.
Disruptive selection: Over time the fish population will change. Medium-sized fish will become rare, and small and large fish will be common is a type of natural selection that is acting on the given population. So, it's B.
What do you mean by Ecosystem?An ecosystem may be defined as any place or area where the members of different species or communities live together and interact with one another for the purpose of food, shelter, and space.
As predators are only able to attack the moderate-sized fishes, so the population of moderate-sized fishes may decline in the aquatic ecosystem, while extremely short and large fishes are able to maintain their population at the same pace.
Therefore, the correct option for this question is B.
