The correct answer is - predator species in a community.
In the terrestrial ecosystems, a very good and usually sure predictor of the biodiversity is the existence of a predator species. The more predator species there are, the higher the biodiversity, and vice versa, the less predator species, the lesser the biodiversity.
The reason why the predators are such a good predictor of the biodiversity is that they are the species that are on the top of the food chain. That means that the predators are dependent for their survival on all the other species bellow them in the food chain, which is pretty much all species apart from themselves.
If a predator is present, than there has to be pray. If there's pray, omnivores and herbivores, than there has to be plants. All of the organisms are connected to one another, and the ones on the top of the food chain are the most dependent on the others, thus their existence usually means a healthy ecosystem with higher biodiversity.
Answer:
The mouse and chicken have the closest relationship of the 5 presented because they have the most shared characteristics through their embryonic development. 3. Why do you think scientists study the embryological development of different species?
Answer:
a green pigment, present in all green plants
Explanation:
The structure of a carbohydrate(sugars) is Carbon, Hydrogen, and Oxygen.
The biggest influence on basal metabolic rate (BMR) is exerted by hormones from the thyroid gland — T3 thyroid hormone.
<h3>What are T3 levels a sign of?</h3>
- A person's thyroid is producing enough T3 hormone when their T3 levels are normal.
- Low levels may be a sign of hypothyroidism, while high levels may be an indication of hyperthyroidism.
- T3 levels, however, can also be influenced by other variables, such as pregnancy and some drugs.
<h3>What takes place when T3 levels are high?</h3>
High total T3 or high free T3 levels in your test findings could indicate hyperthyroidism.
You may have hypothyroidism, a condition in which your body doesn't produce enough thyroid hormone, if your T3 levels are low.
To assist in the diagnosis of thyroid illness, T3 test results are frequently matched with T4 and TSH test findings.
