How does DNA influence physical traits

Answers

Answer 1

Answer: Deoxyribonucleic acid, also known as DNA, is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. This means that all of the DNA from the two living organisms that made you, you're parents, gave you. You look like your parents, grandparents, or other relatives because of DNA, Deoxyribonucleic acid.

What is the steepness of a line on a graph called

Answers

It is called a slope. A slope pointing downwards like this slash \ is considered a negative slope. If a slope pointing upward like this slash / then it is considered a positive slope. What if you had a line on a graph not pointing in either of those directions? If it were pointing straight up like this, | then it would be known as an undefined slope. Last but not least, if you had a line on a graph straight across like this, ____ then it would be zero slope :D

Hope this helps and is a little clear to understand :)

Are mushrooms, producers, consumers, or decomposers?

Answers

The answer is mushrooms are considered to be decomposers. Mushrooms are considered to be a fungi, which means that they create their own food by decomposing organisms, they also absorb nutrients from the organism they absorb. Mushrooms releases enzymes for them to be able to decompose and absorb nutrients from an organism.

Mushrooms are decomposers.

Explanation:

Mushrooms are also known as fungi. Fungi breaks down nutrients from dead animals, rotting food, or decaying plants. Fungi are natural heterotrophic organisms meaning they are incapable of photosynthesis, they cannot grow on their own like plants. They get nutrients from dead animals, rotting food, or decaying plants.

Example 1:

Think about it, bees produce honey as a main source meaning they are producers. Mushroomsdo not have any sort of ability to do so.

Example 2:

Mushrooms might consume nutrients and such but they are not like dragonflies that are big eaters and consume butterflies and bees.

The final explanation, mushrooms are decomposers.

Hope this helps!

A sample contains 100 g of a radioactive isotope. How much radioactiveisotope will remain in the sample after 2 half-lives? OA. 50 g
OB. 25 g
OC. 75 g
OD. 100 g

Answers

Answer:

B. 25 g

Explanation:

Given:

The initial mass of radioactive isotope is, $m_0=100\ g$

There is exponential decay of the isotope with time.

Half life means the time in which the given mass reduces by half. For every half life, the mass reduces by half of the previous mass.

So, for the first half life, the mass that remains is given as:

$m_1=(m_0)/(2)=(100)/(2)=50\ g$

Now, for the second half life, the mass 50 g is again reduced to half.

So, the mass that remains after 2 half-lives is given as:

$m_2=(m_1)/(2)=(50)/(2)=25\ g$

Therefore, the radioactive isotope that will remain in the sample after 2 half-lives is 25 g.

Answer:

its 12.5 g for anyone else who had different options
