Answer:

To establish the age of a rock or a fossil, researchers or scientists use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

1.Identify the role of endocrine glands in growth/development, and in regulation of metabolism.
DIA [1.3K]

In this question we are going to answer a series of questions about the human endocrine system, hormone release and homeostasis.

<h3>What is human endocrine system, hormone release and homeostasis?</h3>

1. Endocrine glands produce hormones and release them directly into the bloodstream.

Hormones are the products of secretion from the endocrine glands. They control various activities in the human body, hence the importance of these glands.

2. It is through the feedback mechanism that, for example, the regulation of hormone secretion and the control of temperature and blood pressure occur.

Thanks to this control, it is possible to guarantee the harmony of the systems and, consequently, the homeostasis (balance of the internal environment).

3. Hormones can be divided into four groups, based on their chemical structure,form of synthesis and storage, solubility, half-life, form of transport, receptors on cell and mechanism of action:

  • Peptides
  • Steroids
  • Amines
  • and Eicosanoids.

Both positive and negative feedback are extremely important for our body to function properly. However, these two mechanisms have differences. In negative feedback, the body produces a response that reduces the initial stimulus, while in positive feedback, the response reinforces the stimulus.

Which might be considered a limiting factor to the amount fish in a lake *
PilotLPTM [1.2K]

Answer:

D). Choice 2 and 3

Explanation:

Given the options above, the limiting factors are both the "Amount of water in the lake" and the "Temperature of the lake"

This is because the amount of water in the lake can only carry as much of the number of fishes as possible it can contain or sustain. This implies that the higher the water content in the lake the higher the number of fishes it can contain and vice versa.

Also, the temperature of the lake is a limiting factor because the temperature of the lake supports the light penetration to the fishes in the water. Should the temperature increases beyond the highest level the water can support, the fishes will die.
