Answer:

9N down

Explanation:

The net force on the ball dropped has a magnitude of 9N and it is directed downward.

Given;

  Gravitational force  = 10N down

  Air resistance = 1N up

<em>Air resistance is an opposite force that acts against a body passing through air. It is a negative force. </em>

<em>Gravitational force is a force acting on a body due to gravitational attraction of the earth.</em>

 Net force  = Gravitational force down - Air resistance up

                   = 10N - 1 N

                   = 9N down

The net force is 9N downward.

After completing meiosis II, human sex cells have a total of _____ chromosomes
vodomira [7]

Ans.

Meiosis involves a type of cell division in sexually reproducing organisms that results in formation of four daughter cells from a single parent cell, having half of the genetic material as in parent cell. Meiosis is divided into meiosis I and meiosis II.

In gamete forming cells of humans are diploid cells and have 23 pairs of chromosomes (or 46 chromosomes). Each gamete forming mother cell undergoes meiotic division to form haploid daughter cells or gametes, each with 23 chromosomes.

Thus, the correct answer is 'twenty-three' as there are 23 chromosomes present in human sex cells at the end of meiosis II.
