Compare and contrast properties of sister chromatids and homologous chromosomes.
lubasha [3.4K]

Answer:

Explanation:

Sister chromatids are regarded as replicated chromosomes. Sister chromatids are two identical copies of chromosomes held at the centromere that are formed as a result of replication. They are identical in the sense that they contain same alleles/gene sequence of the same genes.

Homologous chromosomes, on the other hand, are similar (in length, centromere position) but non-identical chromosomes. Homologous are non-identical in the sense that they may contain different alleles of a gene and are received from each parent. homologous chromosome contain four chromatids; two of which are sister chromatids and non-sister to the other two.

Both undergo meiosis where homologous chromosomes separate in meiosis I while sister chromatids separate in meiosis II but only sister chromatids undergo mitosis.

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of___.
dmitriy555 [2]

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.

A. 7.5 feet

<u>Explanation:</u>

Wave base defines the depth of the water when it is in still condition.

Wave base is half of wavelength.

Wave base = wavelength/2

Given,

Wavelength = 15 feet

So, wave base = 15 feet/2 = 7.5 feet

When the wave height is divided by wavelength then it gives the steepness of the wave.

Therefore, the wave base is 7.5feet.
