if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is
larisa [96]

Answer:

The age difference between the oldest and the youngest is 48.

Explanation:

Given the following data;

The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.

The ratio of the ages of Esinam (E) and Larry (L) is 3:5.

The sum of the ages of all three is 147.

Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);

LCM of 3,5 = 15.

Hence, the ratio of the three ages is now;

K:E:L = 9:15:25

Let their ages be denoted by x;

K:E:L = 9x:15x:25x

The sum of all three ages is;

9x + 15x + 25x = 147

49x = 147

x = 147/49

x = 3.

To find the age difference between the oldest and the youngest;

The oldest is Esinam = 25x

The youngest is Kisii = 9x

Therefore, 25x - 9x = 16x

Substituting the value of x, we have;

x = 3; 16x = 16(3) = 48.

The age difference between the oldest and the youngest is 48.

According to your worldview, what value does a human person have? How does your position affect your stance on controversial bio
nalin [4]

A human life is so valuable that no single price should be placed on it. The effect on this stance on bioethical issues however, is relative.

<h3>Relativity of Human value to Bioethical issues</h3>
  • A person's stance on a bioethical issue can be based on which human life they value more, the person that will gain, or the one that will be affected.
  • With abortion, one might argue that the value of the mother is higher than the baby's because not having to take care of a child will give her a better life.
  • Designer babies might be more valuable because their lower rate of birth defects mean that they are tougher and less expensive to maintain.
  • Stem cell research could save many lives so more value might be placed on these lives than the embryos affected.

In conclusion, a person can see another life as valuable yet have relative views on bioethical issues.

Which human body systems interact to perform temperature regulation along with the nervous and endocrine systems?
Ede4ka [16]

Answer:

Hypothalamus of human body system interact to perform temperature regulation along with nervous system and endocrine system.

Explanation:

Hypothamus is an important part of our lower brain that play a significant role in regulation of body temperature.

   Hypothalamus works with nervous system along with the other parts of our body such as blood vessels,skin and sweat gland to maintain temperature homeostasis of human body.

  When our body temperature rises at that time hypothalamus slows down the rate of metabolism of our body to restrict further increase in our body temperature and also dilates the blood vessels present beneath the skin so that body can liberate heat to the environment.

 on the other hand when the body temperature decreases at that time hypothalamus increases the metabolic rate of our body to increase the body temperature and also the constrict the blood vessels present under the skin.
