Answer:

<em>The result of the union will be ' All future somatic cells of the organism will contain the (2n + 1) number of chromosomes. '</em>

Explanation:

As we know, fertilization is a process in which the egg cell and the sperm cell join to form a zygote. If an egg cell which contains n+1 number of chromosomes joins with a sperm cell containing n chromosomes, then the zygote formed will have n+n+1 i.e 2n + 1 number of chromosomes.  The zygote  goes through multiple cell divisions to form different cells. All the somatic cells are formed by mitosis. As mitosis produces identical daughter cells hence, all of the somatic cells will have 2n + 1 number of chromosomes.

QUESTION 1
nata0808 [166]

Answer:

According to the sliding-filament model of contraction, the muscle contraction occur due to the myosin heads propel the actin myofilaments toward the center of the sarcomere. This pulls the Z disks closer together, shortening  sarcomere and the entire muscle

Explanation:

In the muscle fiber there are two proteins that facilitate the process of contraction, myosin and actin. Myosin is thicker and more abundant than actin, and its interaction is responsible for the process of muscle contraction.

Both molecules, myosin and actin, form bonds -called cross bridges- where the myosin heads produce the mobilization of actin towards the center of the sarcomere. Z discs are associated with actin myofibrils, so they come close, and promote the shortening of the sarcomere.

This process requires the action of calcium ions, which depolarize the muscle cell and consume energy in the form of ATP.

It should be noted that the myosin and actin molecules do not change their length, but their action causes the muscle fibers to shorten during contraction.
