Why is the carbon cycle important to plants

1 answer:

3 0

Answer:it described how carbon is recycled between earth's biosphere, hydrosphere, geosphere and atmosphere. Carbon is an essential element for all life forms so understanding how it is recycled will help us to understand factors and all the biological processes that influence them.

Use the pH color scale. It shows acidity level of both acids and bases. You dip one of the pH strips into whatever liquid you choose, and then compare the new color of the pH strip to the colors on the scale. This will tell you the level of acidity. pH scale can be found below. As you can see, the brighter colors are more acidic than the darker and duller colors.

Which physical properties do all-stars have? Check all that apply.

olga2289 [7]

Answer:

-Physical properties possessed by all stars:

They are made of gases such as hydrogen and helium.
They shine very brightly due to interaction of hydrogen and helium at appropriate pressure and temperature.
They contain iron in their cores which monitors the fusion reaction.
They make energy through fusion between the gases present in the stars which are hydrogen and helium.
They are not spherical in shape hence this physical property is false in terms physical properties of the stars.

Hope this helps. If it does, please mark me brainliest.

Choose all of the ways that cellular respiration is different from photosynthesis. Select the 4 correct answers. *

shepuryov [24]

Answer:

It uses glucose as a reactant.

It uses oxygen as a reactant.

It makes ATP.

It happens in the mitochondria.

Explanation:

It occurs in cells. - this is false. Both cellular respiration and photosynthesis occur in cells.

It uses glucose as a reactant. - this is true. Cellular respiration uses glucose as a reactant, it is broken down to release energy. Photosynthesis produces glucose.

It uses oxygen as a reactant. - this is true. Cellular respiration uses oxygen as a reactant. In contrast, photosynthesis releases oxygen as a byproduct

It makes ATP. - this is true. Cellular respiration makes ATP. Photosynthesis uses energy to produce the sugar which is used in cellular respiration to synthesise ATP.

It happens in the chloroplasts. - this is false. Photosynthesis occurs in the chloroplasts, not cellular respiration

It happens in the mitochondria. - this is true. Respiration occurs in the mitochondria, whereas photosynthesis occurs in the chloroplasts.

It involves oxygen, glucose, carbon dioxide, and water. - this is false, Both photosynthesis and cellular respiration involve oxygen, glucose, carbon dioxide, and water. Photosynthesis produces oxygen and glucose using carbon dioxide and water. Respiration produces glucose and carbon dioxide using water and carbon dioxide.

Generally speaking, which of the following mutations would most severely affect the protein coded for by a gene?a) a base substi

Pavlova-9 [17]

Answer:

Answer is C.

Explanation:

For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.

Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.

justify the following statement “thinking and new ideas advance science, not just the design of instruments” please help

Anna [14]

Answer:

Designing some instruments does help science, but it doesn't advance ideologies of science.

Explanation:

Science is based on theories and laws. Scientists are constantly trying to explain the concepts of the universe by ideas. Sure, instruments do help scientists gather information and such, but ideas and philosophies, theories and laws are the ones that are most important. Without new ideas in science, we would not be able to hypothesize many things, or even develop new instruments.
