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.

Answer:

Weight gain and depression are symptoms caused by imbalance of pituitary and adrenal glands and the cortisol hormone.

Explanation:

The pituitary gland is responsible for the overall functioning of the body since it produces a variety of hormones. It is very small in size and is also known as the 'master gland'. It is made of two parts- <u>anterior pituitary gland and posterior pituitary gland</u>. The pituitary gland and its functions are controlled by the hypothalamus.

The anterior pituitary secretes hormones which act on adrenal glands, thyroid, testes and ovaries. The hormones produced are <em>TSH, Prolactin, Luitenizing Hormone, Cortisol, Testosterone</em>, etc.

Cortisol is produced by the <u>adrenal gland</u> under the command of <em>pituitary gland</em>. Cortisol helps in <em>regulating blood sugar, blood pressure</em> and helps in reducing inflammation. Any imbalance of adrenal gland will cause an increase or decrease in the production of cortisol. The symptoms produced on the imbalance are:

  • Obesity in upper body
  • High blood pressure
  • Mood swings, depression and irritability
  • Acne and other skin problems.

Answer:

A. Object A but not Object B  

Explanation:

Speed = distance/time

A straight slanting line indicates a constant speed.

A horizontal line means that the distance is not changing, that is, the object has stopped.

The graph for Object B shows that it starts and stops repeatedly.

Why do oceanic plates subduct continental plates
Debora [2.8K]
<span>Because they are composed of material that is denser than that of the continental crust. As such oceanic crust is less buoyant than continental crust and so where oceanic crust collides with continental crust, the oceanic rust tends to be forced beneath the continental crust.</span>
