A. Fruit flies mate randomly regardless of how they were bred.
B. Fruit flies can adapt to eating different food sources.
C. Fruit flies prefer the container where they were bred.

Answer: The correct answer is -

Option D.

Explanation:

As per the given information in the question, initially fruit flies were in two different containers having different food sources for several generations. Due to this, they got adapted to the specific food sources to which they were exposed. As a consequence, they started preferring mates that were adapted to the same food source.

Therefore, when fruit flies from the two containers were put together, Fruit flies preferred mates adapted to the same food source.

Thus, option D) is the right answer.

Where should the label for the dependent variable be written for this scatter plot?
Nezavi [6.7K]

Answer:

B. Position B

Explanation:

The values for dependent variable are plotted on the y-axis (vertical) on a scatter plot. Therefore, the label for the dependent variable would be written along the vertical axis for the scatter plot, at position B.

The label for independent variable would be written along the horizontal axis for the scatter plot, at position C.

The answer is "B. Position B"

Ill give brainliest to anyone who helps me with this
zalisa [80]

Answer:

Explanation:

The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.

In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.

Which is the main reason cells are replaced in the body?. The cells are too large.. The cells are inactive.. The cells are damag
anygoal [31]

The right answer is The cells are damaged.

Take the example of skin cells.  

The skin consists of two tissues:

* the outermost, the epidermis, resting on a vascularized connective tissue,

* the dermis.

In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.

On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .
