The rate of decay C
To establish the age of a rock or a fossil, researchers 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.
Answer:
A is the answer, this is because deposition has been happening on earth for ages so as time goes by more deposits form layers on earth, including the remains of animals and plants that would later become fossils.

PLZ thank and five star
and a brainliest would be nice:-)
Answer: D. the amount of space something takes up
============================================================
Explanation:
For example, if you have a 2 inch by 3 inch by 5 inch rectangular block, then the volume it takes up is 2*3*5 = 30 cubic inches. We can fit 30 smaller unit cubes in this 2 by 3 by 5 block.
Another example of volume would be saying that a container can hold 5 gallons, which is the amount of liquid inside the container when it's completely full.
----------
Extra info:
Choice A is false because a substance that does not have a definite shape would be a liquid. Liquids can flow and form to fit any volume. This also applies to a gas as well.Choice B is false because this refers to a solid. A block of ice has a definite shape which is in a block or cube form. Melting that ice will turn it into a liquid which then doesn't have a set shape.Choice C is false as this likely is talking about temperature. Temperature is the measure of how fast a particle is moving. The faster the particle, the more energy and higher temperature it has. On a cold day, the air particles aren't moving as fast compared to a much warmer day when they speed up more.What are two climate feedback mechanisms that are taking place on or around the Antarctic ice shelf?

Which best describes when the body is working on counteracting an effect?
when hormone levels in the body are all equal
during a negative feedback loop
during a positive feedback loop
when the hypothalamus is signaling the pituitary gland
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.
2. When populations are separated into different environments..... *
O Natural selection evolves differences in their body structures.
They immediately develop large differences in structures.
They experience stability over very long periods of time.
They still communicate to go over their differences and how to adapt.
Answer:
MY NAME IS JEFF
Explanation:
When populations are separated into different environments, natural selection can lead to the evolution of differences in their body structures over time. This process is known as divergent evolution, and it occurs when populations that were once similar become increasingly different as they adapt to their respective environments.
What is the explainer to the question asked ?
Over time, populations may develop large differences in their structures as they evolve to better fit their respective environments. For example, if one population lives in a forest environment with lots of trees and vegetation, it may evolve longer limbs and more flexible joints to help it move through the trees.
In contrast, a population living in a grassland environment may evolve shorter limbs and a more compact body shape to help it move quickly across open ground.
While populations may experience stability over long periods of time, this is not always the case. Changes in the environment, such as shifts in climate or the introduction of new predators or competitors, can lead to further evolution and adaptation.
While populations that are separated into different environments may develop differences in their body structures, they may still communicate and exchange genetic material with each other if they come into contact again.
Therefore, This can lead to the exchange of beneficial traits and the potential for hybridization, which can create new genetic combinations and potentially new species over time.

Why are monarch butterflies poisonous?
How do predators know they are poisonous?
How does a monarch's coloration help both the butterfly and the predator?
Answer:
Explanation:
The milkweed plant also has high concentrations of cardiac glycosides in its sap. ... In addition, the caterpillar of the monarch butterfly dines exclusively on the sap of the milkweed plant, rendering both the caterpillar and butterfly mildly toxic as well.
Predators know that monarch butterflies are poisonous because of their bright coloration, which acts as a warning that they are poisonous.
This coloration warns potential predators that the animal contains poisonous chemicals. Warning coloration may work particularly well in adult butterflies because the hard body and wings allows a predator to bite the adult, taste the poison, and release the butterfly without killing it.

How are some humans using more than their fair share of water? What is the effect of using water on environmental systems?
Please write a full paragraph and cite evidence.
Answer:
Some humans are using more than their fair share of water and it is having a huge impact on the environment. People tend to let their water run while brushing their teeth or shaving, and those are just two of the major problems. There may also be leakages, which can waste gallons among gallons of water. Wasting water hurts humans, it leaves them with less accessible, usable water. Additionally, wasting too much water can hurt the local environment as it drains too much water away from the natural ecosystem.
