Answer:
The correct options are A,C and E.
Explanation:
In geology, plateaus can be described as uplifted areas that are generally flat from the upper surface. The formation of plateaus takes millions of years. They are also called as tablelands due to their structure.
A plateau might form when the magma inside the Earth cooled and is raised above the surface of the Earth's crust. It can also be caused due to an erosion of a mountain generating lava.
Answer:
natural selection
Explanation:
Darwin proposed <u>natural selection</u> as the process that causes evolution.
According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.
<em>For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.</em>
The purpose of the cell membrane is to hold the different components of the cell together and to protect it from the environment outside the cell. The cell membrane also regulates what enters and exits the cell so that it doesn’t lose too many nutrients, or take in too many ions. It also does a pretty good job of keeping harmful things out.Ions and large polar molecules cannot pass through the lipid bilayer. But more specifically, whether a molecule can pass through the membrane depends on its size and its electrical nature. The membrane is highly permeable to non-polar (fat-soluble) molecule.
The correct size order from the smallest to the largest is:
Animal cell >> Mitochondrion >> Ribosome >> Hexokinase >> ATP >> O2
- The animal cell size is about 20 to 30 micrometers (μm), although it varies according to the type of the cell.
- The average mitochondria size is approximately 0.75 to 3 μm. The size, number, and structure of mitochondria in an animal cell vary according to type of animal cell.
- The ribosome size is approximately 0.02 μm in diameter.
- An enzyme is a macromolecule whose size is variable (its average size is 3–7 nanometers, i.e., 3-7 nm). A micrometer (μm) equal to 1000 nm.
- The adenosine triphosphate or ATP (the energy coin of the cell, which is composed of a five-carbon sugar, three phosphate groups, and adenine) and molecular oxygen (O2) are both simple molecules whose sizes are very small compared to enzymes.
