Answer:

This definition suits that of "HOMOLOGOUS CHROMOSOMES"

Explanation:

Homologous chromosomes are similar pairs of chromosomes i.e. in length, gene positioning and centromere location (one from each parent) but not identical. Homologous chromosomes are not identical in the sense that, alleles on each pair may be different, resulting in genetic variation of the offspring.

Using humans as a case study, a karyotype (pictorial display of chromosomal arrangement) shows the complete set of chromosomes, which has two complete set (diploid). Each human cell contain 23 pairs of chromosomes, with each pair contributed by each parent i.e. 46 chromosomes in total. Every chromosome pair represents a set of homologous chromosome.

Answer:

HOMOLOGOUS CHROMOSOMES are chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location.

Explanation:

A Homologous chromosome is a two sister chromatids attached with cohesions to form a tetrad. It has the same genes but may have different alleles for each trait. They are similar in nature and not identical in nature.

E.g, A Human cell has 23 pairs of chromosomes, with a total of 46 chromosome per cell. Each chromosome pair stands for a set of homologous chromosomes.

A. long wavelength; small

Diffraction is the greatest whenever the gap where the wave is passing through is smaller. This gap property will make the wave to "curve" reaching a more wider area, the smallest the gap is, more the wave will curve, spreading more widely. The light would propagate more rather then being concentrated on one focus. The wavelength is also something that affects diffraction. Whenever the wavelength is longer, the wave will have more time to spread sideways after diffraction.

How does deforestation affect the environment?
Vinil7 [7]

The answer is C, it results in more carbon dioxide in the air.

Trees use carbon dioxide in photosynthesis, and produce oxygen.

It can't be either A or B, as it increases soil erosion (less roots), and decreases habitats.
