Answer:

Argon

Explanation:

Argon is actually used to determine the age. It's called potassium-argon dating b/c when volcano erupts the rocks in it contain potassium. The potassium slowly decays and produces argon. Scientists measure how much argon is in a given volcanic rock and do math backwards to figure out how many potassium atoms were needed to produce the given amount of argon. We already know the rate at which potassium decays so then they put two and two together to find the age.

Here's a link with some cool info on it:

lora16 [44]
I would guess rainforest because it’s an reptile/amphibian it appears and those animals need water to survive. There isn’t much water in the dessert.

Why are red blood cells unable to replace damaged proteins
Rainbow [258]

The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.

Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.

DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm,  then translating or decoding this information, which results in the making of protein.

Question 8 of 10
Fynjy0 [20]
I believe it’s A but I’m not too sure


Reason; Warm air rises, and when it rises it becomes cooler. ... If the pressure of the surrounding air is reduced, then the rising air parcel will expand. The molecules of air are doing work as they expand. This will affect the parcel's temperature (which is the average kinetic energy of the molecules in the air parcel).

Which of the following are limiting nutrients ?
OleMash [197]

Answer:

Nitrogen and Phosphorus

Explanation:

When the function of a whole ecosystem is limited because of a nutrient , which is present in limited amount, it is called as a limiting nutrient. The organisms uptake water and carbon directly from the environment as it is abundant in nature. The nutrients like nitrogen and phosphorous are present in limited amount and moreover they are not present in the form that can be directly taken up by the organism.

Thus, Nitrogen and Phosphorous are limiting nutrients.
