8 0

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

Cutting down forests changes the populations of more than trees. Imagine the organisms that lived in this forest. After the tree
Alex_Xolod [135]

Answer:

<em>Food and shelter are the most likely limiting factors in this case.</em>

Explanation:

In a forest, the huge trees act as a source of shelter for the animals that live in that habitat. It protects the animals from the heat of the Sun and extreme cold conditions.

The tress in the forest are the primary source of food for almost all the organisms that live in the forest. Cutting down trees will lead to food scarcity for the animals which inhabit that forest. As a result, the animals will either have to migrate or they will become die due to lack of food.

Hence, food and shelter are the limiting factors in this case.
