When the temperature reaches 0˚C (32˚F), the top layer of the lake freezes and turns into ice. In solid form, water molecules are less dense and thus ice floats on the top of the lake.
This solid barrier prevents any wind-induced mixing as well as protects the relatively warm water underneath. Furthermore, light is also blocked so that photosynthesis is inhibited during this period. As the lake water is separated from the atmosphere, no direct oxygen diffusion occurs.
All these factors together causes a more even distribution of nutrients and gases in a lake in winter.
Answer:
Glucose utilization would increase a lot.
Explanation:
Aerobic condition indicates the presence of large amount of oxygen in the body. Anaerobic condition means that the oxygen is limited or deficient in the body.
The muscle cells shows anaerobic condition during exercise and produces lactic acid. Since, the ATP demand is same in both the aerobic and anaerobic conditions. This increases the demand of glucose in the body. Glucose utilization is increased to provide proper energy to the individual.
Thus, the correct answer is option (a).
The answer is: The <span>exocrine structure that is involved in the digestion of fat is </span>liver.
<span>>The liver plays an vital role in the digestion and processing of proteins, fat and sugar.
</span><span>>The liver plays a significant role in fat digestion as well as the production of fats needed for the function of different organs of the body</span>
Answer:
The right answer are : mitosis, diploid cells, and identical DNA.
Explanation:
The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.
Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.

Explanation:
Between all these kids carrying out this discussion, Tamara is the closest to guessing what scientists do. There is indeed a definite set of steps that scientists undertake in order to conduct science experiments. The scientific method is as follows:
- observation
- measurement
- experiment
- testing the hypothesis
