Answer:
2 chromosomes
Explanation:
The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.
Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.
The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.
Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.
This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.
Answer:
The researchers add a compound to the cell growth medium that both binds and releases protons (H+) and also pass through lipid membranes. The effect that the added compound will have on the ATP production by the cells is that ATP synthase will stop.
The flowering plant does not wilt but stands straight up reaching toward the sunlight because its cells contains mostly... Water. The answer is Water. I hope this helps!

Answer:
d. The dependent variable is the vitamin C levels in the pineapples and oranges.
Explanation:
<em>Select all the statements that are true about this experiment.</em>
a. The independent variable is temperature. NO, temperature, as well as rain and sunlight are controlled variables and are not being evaluated in the experiment.
b. the control group in the experiment is the oranges. NO, there is no control group in this particular experiment.
c. The type of fruit is a controlled variable. NO, the type of fruit is the independent variable.
d. The dependent variable is the vitamin C levels in the pineapples and oranges. YES. According to your hypothesis, the vitamin C levels depend on the type of fruit.
