No coloque ningún plástico en el horno, incluidas las cestas o bandejas de plástico para sostener la cristalería. Las esporas de las bacterias son muy resistentes al calor y no se eliminan por ebullición a presión atmosférica. En el aula, se puede usar una enlatadora a presión para esterilizar líquidos.

How do the Earth and Moon compare in terms of gravitational force?

Law Incorporation [45]

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.

Option A

<u>Explanation:</u>

According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.

In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.

$F=\frac{GM}{R^{2} }$

So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.

A cell in the testes of a male bald eagle is getting ready to begin meiosis. The diploid number for this bird species is 66. How

Ostrovityanka [42]

Answer:

Replicated chromosomes at metaphase I = 66

Sister chromatids at metaphase I = 66 x 2 = 132

Sister chromatids at prophase II = 66

Chromosomes in each sperm cells = 33

Explanation:

Metaphase I of meiosis I would have 66 replicated chromosomes in the testicular cells of the bird. Each of the replicated chromosomes would have two sister chromatids. So, a total of 66 replicated chromosomes would have 66 x 2 = 132 sister chromatids.

Due to segregation of homologous chromosomes towards opposite poles in anaphase I, each daughter cell formed by the end of meiosis I would have 33 replicated chromosomes. So, each of the daughter cells would have a total 33 x 2 = 66 sister chromatids at prophase II.

Since meiosis II maintains the chromosome number, each sperm cell formed by the end of meiosis II would have 33 chromosomes.
