What factor limits the number of eclipses per year

Biology
1 answer:
labwork [276]3 years ago
5 0

Answer:

"Option B. The tilt of the moon´s orbit around the earth " limits the number of eclipses per year

<u>Explanation</u>:

The moon's orbit is tilted only by 50^{\circ}. Around the sun when the earth and moon move, the tilt of the moon changes according to the direction of the sun. When the same thing occurs to the earth, the seasonal changes occur. The theory is all related to moon's formation. Due to this tilt the moon's road near the stars changes slightly in every month. The inclination is with respect to the ecliptic plane. If this inclination was absent then we could have felt the eclipse more frequently.

What is one condition that must be met for a population to be in genetic equilibrium? A. There is nonrandom mating. B. There is
Ksenya-84 [330]

Answer:

C. There is no genetic drift

Explanation:

A population is said to be in genetic equilibrium when the genetic variation of a population remains constant over many generations.

For a population to remain in genetic equilibrium it is necessary that external factors that disturb the equilibrium should not be present.

The external factors that are responsible for disturbing the genetic equilibrium are mutations, non-random mating, genetic drift and gene flow.

Genetic drift occurs when due to a chance event the allele frequency of a population either increases or decreases and this is usually common in small populations.

Thus, genetic drift should not occur so that the population can be in genetic equilibrium.

e-lub [12.9K]

Answer:

The correct answer is fungi.

Explanation:

Fungi are the eukaryotic organism but they can be present in unicellular and multicellular form. They are different from plant, animals, and bacteria. They are heterotrophic organisms and do not conduct photosynthesis. Their cell wall is made up of chitin.  

Most of the fungi are saprophytes which means they take their nutrition from the dead and decaying organism. So fungi play an important role in clearing the waste organic material from the environment so they help in bioremediation. All members of fungi comes under a separate kingdom fungi.
