The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.
Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.
Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.

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.

Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
