The correct answer is (a.) moderate temperatures. The moderate temperatures allow Earth to maintain bodies of water into its normal state. Changes in the bodies of water in terms of volume and structure would change due to the change in temperature.
The correct option is C.
Homeostasis refers to the method by which living organisms regulate their internal environments. The conditions that surround the living cells has to be kept at the optimum level because the survival of the organism depend on it and this is what homeostasis does.
Answer:
The answer is (1) It initiates a cascade.
Explanation:
Signal transduction pathways regulate many important cellular functions such as growth, differentiation, metabolism, and survival. Many of these signaling pathways are altered in human cancer.
<em>Receptor tyrosine kinases </em>are cell surface receptors that play a role in the signaling pathways governing cellular processes of metabolism, intercellular communications, differentiation, survival, and proliferation.
They bind to their corresponding growth factors, triggering the downstream signaling cascade.

Variation is any difference in organisms of the same species, whereas gradualism is a microevolutionary theory.
<h3>What is a scientific theory?</h3>
A scientific theory is a given explanation on a phenomenon from the real world (e.g., the evolution theory).
The fossil record is a piece of evidence for the evolution theory (which is mainly based on natural selection).
In conclusion, variation is any difference in organisms of the same species, whereas gradualism is a microevolutionary theory.
