4 0

Answer:

A-G-C-T-T-A

Explanation:

The nitrogenous base-pairs are Adenine (A)—Thymine (T) and Cytosine (C)—Guanine (G).

Adenine on one strand of a DNA molecule means thymine on the complementary strand, and vice versa.

Cytosine on one strand of a DNA molecule means guanine on the complementary strand, and vice versa.

A gene is a specific portion of a DNA molecule that codes for a trait.

Ozone layer is the area of the upper atmosphere, between around 15 and 35 km over Earth's surface, containing generally high groupings of ozone particles (O₃). Roughly 90 percent of the environment's ozone happens in the stratosphere. The ozone layer successfully squares all sun oriented radiation of wavelengths under 290nm from achieving Earth's surface, including certain kinds of UV and different types of radiation that could harm or kill most living things.

Answer:

Answer is D.Produce non-identical genetically different gametes and reduction of chromosomes,creating a haploid gamete.

Explanation:

Meiosis is essential for sexual reproduction.In humans diploid gamete-mother cells or germ line undergo meiosis to produce haploid gametes.

The chromosomes pairs of each parent undergo crossing over during meiosis.so daughter cells i.e gametes have genetic variations.When gametes  fuse and form zygote ,its genetic make up is different from both parents.thus meiosis allows a species to bring variations in next generations.Benenficial variations help organisms to adapt to the changes in environment.
