Precipitation moving from higher to lower elevations on the ground is called___?
Answer:
Evaporation
Explanation:
Evaporation is the process in which percipitation moves higher to lower elavations on the ground. Evaporation is when the sun heats up and dries out the water causing it to rise up to the clouds which then causes rain for another time. ( I am not completely sure)
why do biomes differ
Answer:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
Explanation:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
For example, the types of organisms found in the subtropical desert differ drastically from the organisms found in a tropical rainforest. Each organism is well-adapted to its environment, and a subtropical desert and tropical rainforest are two very different biomes.
If you look at the graph below, you can see that the tropical rainforest has high average temperatures and high precipitation, whereas subtropical deserts have much lower precipitation and great variation in average temperature.

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statement into the correct box. some statements may apply to more than one type of microscopes. Some statements may not be used.
Answer: Light microscope:
use a beam of light to produce magnified images
can be used to examine living cells and tissues
Scanning electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Transmission electron microscope:
use a beam of electrons to produce magnified images
can be used to examine DNA
can be used to examine cells
Explanation: Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.
Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:
1. Scanning electron microscope(SEM): an electron beam passes over the specimen's surface and displaces electrons which are then focused on a screen to form an image. Images appear in 3-D
2. Transmission electron microscope: electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D

There is a strong relationship between organism complexity and genome size in eukaryotes. Select one: True False
The statement 'There is a strong relationship between organism complexity and genome size in eukaryotes' is FALSE. The genome of an organism is all genetic information of that individual.
The genome is represented by all nucleotide (DNA) sequences that form the genetic makeup of an organism.
The genome is composed of protein-coding genes and non-coding sequences, which often exhibit regulatory functions.
The proportion between protein-coding sequence and non-coding sequence is not linear, thereby the complexity (i.e., the amount of different types of proteins encoded by the genome) and genome size in eukaryotes is variable among species.

How did reduced methane concentrations in the atmosphere affect Earth?
Earth warmed.
Earth cooled.
Volcanic activity decreased.
Volcanic activity increased.
Answer:
Earth cooled
Explanation:
Here are all the answers for that quick check:
1. Which option orders the events chronologically, from earliest to latest.
Answer: Single-celled organisms increase atmospheric methane concentrations. Photosynthesizing bacteria release oxygen into the sea. Oxygen concentrations increase in the atmosphere. Many new animal species evolve.
2. Which forms of life were dominant in the Mesozoic era?
Answer: Reptiles
3. How did the success of photosynthetic bacteria change Earth’s atmosphere?
Answer: increased oxygen concentration
4. How did reduced methane concentrations in the atmosphere affect Earth?
Answer: Earth cooled.
5. Which characteristic defines the Paleozoic era?
Answer: Animals with shells and hard parts were dominant for the first time.
You're welcome.
Answer:
Earth cooled.
Explanation:
The reduced methane concentrations in the atmosphere affect Earth :
Particles of gas and dust released into the atmosphere during a volcanic eruption affect the climate. Most of the particles emitted by the volcano cool the planet by blocking incoming solar radiation. The cooling effect can last from months to years, depending on the nature of the eruption.Therefore, the Earth is cooled.

What do all living things have in common? All have cells with a nucleus. All have a genetic code. All are made of two or more cells. All can perform photosynthesis.
Living beings are organisms that can respire, respond, grow, reproduce, and are made of cells. All living things have a genetic code. Thus, option B is correct.
What is a genetic code?A genetic code is a sequence of proteins and nucleic acids that act as a hereditary molecule that transfers the traits and characteristics to the progeny.
The code can be in the form of DNA or RNA and provides information about the genotype of the organisms that were passed from their ancestors.
The genetic code is in the form of triplets and is a universal system that codes for the same proteins in all organisms. It consists of the nitrogenous bases that through translation make the amino acids.
Therefore, option B. all living organisms have a genetic code.

If a DNA molecule had a total of 1000 nucleotides and 200 of these are adenines, what would be the total number of pyrimidines in this molecule?
If a DNA molecule had a total of 1000 nucleotides and 200 of these are adenines, then the total number of pyrimidines is 500. Adenines (A) are purine bases.
DNA is a double helix molecule composed of two long chains of nucleotides that are held together by hydrogen bonds.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).
Adenine (A) and guanine (G) are purines, whereas cytosine (C), thymine (T), are pyrimidines.
According to the base pair rules, Adenine always pairs with Thymine, whereas Guanine pairs with Cytosine.
In this case, the number of A + T is equal to 400 (200 + 200) and the number of G + C is 600 (300 + 300), thereby the number of pyrimidines or C + T is equal to 500 (200 + 300).
