Sebum is secreted into hair follicles by sebaceous glands. Sebum is an oil that protects the skin from outside elements and keeps it nice and moist.

Suppose there was NO meiotic recombination but maternal and paternal chromsomes still assorted randomly during meiosis. How many
polet [3.4K]

Answer:

8,324,608 chromosome combinations

Explanation:

During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.

identify and describe the characteristics of solar and lunar eclipse PLEASE I WILL GIVE BRAINLIEST TO WHOEVER ANSWERS
frosja888 [35]

From our perspective on Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon.

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse.

Lunar eclipses can only happen when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon. But lunar eclipses do not occur every month because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun. Without the tilt, lunar eclipses would occur every month.

Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.
