Answer:

Through Mutation

Explanation:

Since our cells are able to produce exact copies of themselves. Thus, until unless some mutation has occurred and affected the ability of the cells to produce exactly similar duplicates copies of the parent cell, there is no way that an individual gets aged.  

Since, mutation affects the mitochondrial DNA it is pretty sure that a mutated cell has affected the longevity of a normal cell and then that mutated cell has produced million other mutated aged cell by replicating itself

Answer:

Is altered by mutation with time.

Explanation:

The older the age more is the process of aging. The aging includes both physical and psychological. The cellular duplication is a process of cell division called mitosis that produces exact copies of the original ones. The mitochondrial DNA mutation with the age is a cause of ageing. The mutation in somatic cells causes decrease in the function of such cells. The somatic mutations are one of the cause of decreasing the ability of cells to make exact copy of it.

Thus, the concept of aging as a result of cellular duplication errors is based on the fact that the body's ability to make new cells that are exact copies of the original ones is altered by mutation with time.

tendons of the rotator cuff muscles hold the head of the humerus to the glenoid cavity of the scapula
AnnZ [28]

The rotator cuff muscles hold the head of the humerus to the glenoid cavity of the scapula with subscapularis, supraspinatus, infraspinatus, and teres minor muscles' tendinous.

What is rotator cuff muscles?

The rotator cuff is a collection of muscles in the shoulder that supports stability of the glenohumeral joint while allowing for a large range of motion. The following muscles make up the rotator cuff: Subscapularis. Infraspinatus. Minor Teres.

What is glenoid cavity of the scapula?

The term "glenoid fossa" refers to the glenoid hollow. The pectoral girdle's lateral scapula bone, often known as the shoulder blade, has a slight dip there.  The glenohumeral joint connects the upper limb's humerus to the glenoid cavity.

The subscapularis, supraspinatus, infraspinatus, and teres minor muscles' tendinous insertions combine to form the tendinous band known as the rotator cuff. During joint motion, these muscles support the humeral head's rotation against the glenoid fossa.

Therefore, the rotator cuff muscles hold the head of the humerus to the glenoid cavity of the scapula with subscapularis, supraspinatus, infraspinatus, and teres minor muscles' tendinous.

Which of the following is an example of specific immunity?
zvonat [6]

Answer:

Immunity to Small Pox

Explanation:

Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

Why do most particles in solar wind not reach Earth’s surface?
Inessa [10]

Answer:

Due to the dense atmosphere

The magnetic field of the earth

Explanation:

Most particles in the solar wind do not reach the earth's surface because the atmosphere is very dense and the protecting magnetic field of the earth.

A solar wind is a burst of energetic particles from the sun which are made up electrons, ions, etc.. They travel at a very high velocity.

  • The magnetic field of the earth is able to deflect these charged particles away.
  • In areas such as the pole, the interact with the atmosphere to produce very stunning auroras.
