What does it mean when scientists say that living organisms share a universal genetic code

2 answers:

6 0

<span>All living organisms have a shared ancestor deep in the past, so all living organisms are related to some degree. We might share 99.8% DNA with chimps, but we also share maybe (just a guess, I don't remember the exact number) 24% DNA with lettuce. If all living organisms are related, than their genetic code is universal - one and the same for all organisms.</span>

vichka [17]

The correct answer is resistance stage.

Hans Selye was a very important endocrinologist working in the field of biological stress. He developed the General Adaptation Syndrome (GAS) which is a model describing an animal's response to stress. GAS is comprised of three stages; the alarm, the resistance and the exhaustion stage.

During the resistance stage, the body's glands produce and secrete several hormones which protect the individual from the perceived stressor. Some of the hormones produced at this stage are the glucocorticoids.

Use Figure 1 to evaluate each trigonometric function of angle A . The side adjacent to angle A has length 8 and the side opposit

jonny [76]

The trigonometric ratios are;

Sin A = 0.78
Cos A = 0.625
Tan A = 1.25

<h3>What are the trigonometric ratio?</h3>

The trigonometric ratios are sine, cosine and tangent. Now we have the hypotenuse of the triangle. Figure 1 has been shown in the image attached to this answer.

c = √8^2 + 10^2

c = 12.8

sin A = 10/12.8 = 0.78

Cos A = 8/12.8 = 0.625

Tan A = 10/8 = 1.25

According to natural selection process, the trend that will occur is that the number of organisms with harmful characteristics will decrease while organisms with neutral or beneficial traits will increase in the plant population

<h3>What is natural selection?</h3>

Natural selection is the process by which organisms with favorable features and characteristics that enable them to adapt to their environment survive while those with unfavorable traits die off.

In a changing environment, it will be observed that the organisms with the most favorable traits will be the most dominant in the environment.

Therefore, for the Year 5 and Year 10, the most likely trend that will occur is that the organisms with harmful characteristics will be decreasing in the plant population while organisms with neutral or beneficial traits will likely be increasing in number.
