Answer: dna replication happens in interphase before the mitosis
Explanation: During interphase the cell’s DNA inside the nucleus replicates forming two strands of DNA or chromosomes. In the interphase the DNA replicates in the S phase. Don’t confuse with G1 since in G1, which comes before S phase, replicates the cellular contents needed for this process

Describe the energy transfer between the water and air if the system is at equilibrium
A.Energy is transfers from air to the water
B. Energy transfers from water to the air
C. Energy transfers back and forth between air and water
D.None of the above
The energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy. So, the correct option is D.
What do you mean by Equilibrium state?Equilibrium may be defined as a condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs.
When the system is at equilibrium, the energy transfer between water and air surrounding the cup does not take place. It will only take place when there is a difference between the concentration of two solutions or objects.
Therefore, the energy transfer between the water and air if the system is at equilibrium does not carry any transfer of energy.

explain how the structure of a book lung allows it to perform its function
Answer:
Book lungs are within small openings in the abdomen of the arachnid. The book lungs themselves consist of a series of haemolymph filled plate-like structures. Between the plates there is an air space and this allows air to circulate around the plates. Gaseous exchange then occurs through the surface of the plates.
Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil
Answer:
The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.
Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.
A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study
Answer and Explanation:
Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.
Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated
A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.
What is Mutation?A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.
According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.
A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.
Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

how does greenhouse effect warm the earth?
Answer:
[tex]\color{Blue}\huge\boxed{Answer} [/tex]
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

25 POINTSSS AND BRAINLY THE SELECTED ANSWER IS WRONG BTW
Answer:
The second option
Explanation:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. That is why cells are so small.

Alex is studying a population of fifty organisms that belong to the same species. Some of the organisms have dark spots, some have light spots, some have no spots, and some have stripes.
How does this species most likely reproduce?
Answer:
Sexual reproduction
Explanation:
There is a significant amount of genetic variation (diversity) here. Asexual reproduction results in little to no diversity, so we can assume this species reproduces sexually. Hope it helps :)
