Caverns are mostly formed in limestone.
Answer:
Because of cell differentiation
Explanation:
Multicellular organisms are organisms that have many cells in their body system, unlike unicellular organisms that have just one. However, these many cells contained in a multicellular organism are of different types performing different functions.
Although they all have the same set of genes encoding the same proteins in them, they are able to become different and perform different functions via a process called CELL DIFFERENTIATION. Cell differentiation is the process whereby cells of a living organism becomes specific in their functions as they divide. This is a result of the REGULATED EXPRESSION OF GENES. The genes in each cell are not expressed at the same time, hence, they have different functions.
Answer:
False
Explanation:
What this sentence is describing is a negative feedback loop, not a positive. A Positive feedback loop causes additional change in the same direction.

trypsin (a protease)
lipase
maltase
Hormones secreted by the pancreas are:

The hunting behaviors of bats are affected by noisy environments because the bats' hunting methods will change to adapt to their noisy surroundings.
In an environment where there is much noise pollution, bats could be affected very negatively, causing the sounds of their prey to become hard to hear or to detect through the sounds of the city. This could lead to one of two things: A decrease in the bat population, or a development of a new hunting technique with in the population, leading to many possibilities with in the genetic gene pool. Studies have been made concerning bats in areas with high levels of noise pollution, and rather than the decline of bats in the population, a new hunting method was developed instead. Bats normally rely on the sound of their prey, as well as their echolocation. In the studies however, scientists found that the bats would begin to rely solely on echolocation, and not a mix of echolocation <u>and</u> the sounds of their prey, <u>just</u> echolocation. This helps the bats to adjust to their noisy environments so that they can better find their prey.
