Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.

What is the greenhouse effect?
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

this is ur ans and tell me if u want its explanation tell me in comment's
Answer:
D) Heat from the sun
Explanation:
sun is so hot it will soak up h2.0 no matter if you can or cannot see it it still happens. so it goes to the clouds and rains when the water gets too heavy.

B. Genetic engineering is the process of DNA forming into proteins.
C. Genetic engineering is a new practice that doctors can use to help just about any health issue.
D. Genetic engineering is the creation of a new species through artificial DNA.
Answer:
A. Genetic engineering is the manipulation of DNA to produce new organisms or molecules.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. ... Genetic engineering involves the direct manipulation of one or more genes. Most often, a gene from another species is added to an organism's genome to give it a desired phenotype.

Provides structure and protection to the cell : The cell wall
Explanation:
What % of energy does plants receive from the sun
Answer:
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.

O
A. Four siblings' cells are similar to their parents' cells.
O
B. Four siblings' cells are identical to their parents' cells.
O
C. Four bacteria daughter cells are similar to their parent cell.
OD. Four bacteria daughter cells are identical to their parent cell.
Answer:
A. Four siblings' cells are similar to their parents' cells.
Explanation:
Genetics of offspring are based on the paten but it will never be identical to them. The reason why is when the male and female cells combine to form a child they mix and most of the time one will dominate the other. You can have cases where you have both alleles though. Sometimes they also mix to form a new one. But usually you'll get one from each parent.
Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?
Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.
Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:
Scale modelsScale populationsIn the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.
The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.
Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

What is the water cycle?
A) A process by which water moves from cloud to cloud in the sky
B) A process by which water is absorbed into soil on Earth's surface
C) A process by which water moves from Earth's surface into the sky and back again
D) A process by which wind washes large amounts of water onto land from the oceans
explain why
according to me the answer is
C) A process by which water moves from Earth's surface into the sky and back again
explanation:the water becomes water vapour due to heat and becomes light in then it goes to higher altitude and cools down and again becomes drops of water which are heavily to hold in air so it starts raining and it comes again to ground and then again heat happens it turns in vapour cools down and moves to earth's surface (in form of rain,snowfall) and this process goes on going continuously this is called as water cycle
SO ur answer is
C) A process by which water moves from Earth's surface into the sky and back again
Answer:
c
Explanation:
A process by which water moves from Earth's surface into the sky and back again

DNA is a genetic material found in every living organism. DNA is made up of purines, pyrimidines, a pentose sugar, and phosphate backbone. DNA is a genetic material that carries information from parent to daughter cells.
The correct answer is:
Option A. Nucleotide bases in one strand can only be paired with specific bases in the other strand.
Characteristics of the DNA include:
1. DNA is a double-stranded genetic material, which is made up of four nitrogenous bases, adenine, cytosine, thymine, and guanine.
2. These nucleotides bind to specific nucleotide sequences present on the template strand of the DNA.
3. DNA consists of coded sequences known as genes, which are inherited from the parent to the daughter cells.
4. DNA undergoes a unique semi-conservative mode of replication.
Thus, the correct answer is the ability of the DNA nucleotides to bind to the specific bases in the other strand.

The Earth’s atmosphere consists of a combination of gases. Scientists believe that we are creating air pollution, which causes an increase in some gases, such as carbon dioxide. Such increases make it difficult for the atmosphere to stay in balance, and heat radiating from the Earth is being trapped. What term refers to the sun’s energy being trapped in our atmosphere?
A) cumulus clouds
B) greenhouse effect
C) transpiration
D) convection
And I need an explanation
Answer:im guessing its the greenhouse effect
Explanation:The Earth's atmosphere is composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). ... Due to increases in gases, like carbon dioxide, that trap heat being radiated from the Earth, scientists believe that the atmosphere is having trouble staying in balance creating the greenhouse effect
