Water is warmed by the sun and
IceJOKER [234]

Answer: The water is warmed up by the sun and then it evaporates into the atmosphere. The sunlight warms the water by its heat.

Water is then cooled down and condensation takes place.

The water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

Water and nutrients that are not recycled on earth are stored in the form of reservoirs.

Hypothesis: If the type of the food available changes, then the frequency of beak types will change, because birds with beaks mo
dangina [55]

The correct answer is: If generation 3 had flock distributions similar to those shown in the graph below.

After the change in food, the beak phenotype changes in order to adapt. So, if fruit is removed, the phenotype of birds’ beaks should change according to the change in environment. The graph below shows that there is no change, so it wouldn’t support the hypothesis that food changes beak types.

A gene includes the sequence AGAACT. When it is transcribed, what will the RNA sequence be? A. UCUUGA B. UGCCGU C. UCUUTC D. TCT
Margaret [11]

Answer:

A

Explanation:

The correct option would be A.

<em>According to the base-pairing rule, Adenine (A) always pairs with Thymine (T) (or Uracil in the case of RNA) while Guanine (G) always pairs with Cytosine (C).</em>

Hence;

             A-U

            G-C

            A-U

            A-U

            C-G

            T-A

Therefore, AGAACT would be transcribed to UCUUGA.

How many sperm cells are formed from an original cell in a Drosophila fruit fly at the conclusion of meiosis?
julsineya [31]

Answer:

C. Four Haploid Sperm Cells

Explanation:

Meiosis is a cell division measure that creates four haploid cells (gametes) from a solitary diploid germline cell. In males, meiosis is essential for spermatogenesis, the cycle to produce sperm. Sperm are the haploid cells that are produced in meiosis.  

Meiosis is a profoundly moderated cell division measure in eukaryotes that produces 4 cells (gametes) from a solitary cell (mother). Nonetheless, Nondisjunction in the male of Drosophila causes much of the time sperm with an addition or loss of chromosomes.
