Humans affect Earth in many ways. The use of fossil fuels, the clear-cutting of forests, and controlled burns can affect the carbon cycle. Which process can help counteract these human interactions? photosynthesis respiration decomposition transpiration
Answer:
Photosynthesis
Explanation:
Photosynthesis takes in CO2 from the atmosphere and utilizes it to form sugars/oxygen.
The equation: 6CO2+6H2O -> C6H12O6 + O2
Respiration will do the opposite and actually release CO2 into the atmosphere
Decomposition will also release CO2 as a byproduct
Transpiration I don't believe has anything to do with removing or putting CO2 into the atmosphere. It's about water movement!

Data that indicate that the genetic code changes frequently.
Data that are inconclusive about the nature of.
the genetic code.
Data that indicate that some organisms use one or more alternate codes.
Data that indicate that the genetic code is the same in all organisms tested so far.
Answer:
hi here is your answer....
Explanation:
Data that indicate that the genetic code is the same in all organisms tested so far.
becuase,
The genetic code is nearly universal, and the arrangement of the codons in the standard codon table is highly non-random. The three main concepts on the origin and evolution of the code are the stereochemical theory, according to which codon assignments are dictated by physico-chemical affinity between amino acids and the cognate codons (anticodons); the coevolution theory, which posits that the code structure coevolved with amino acid biosynthesis pathways; and the error minimization theory under which selection to minimize the adverse effect of point mutations and translation errors was the principal factor of the code’s evolution.

How are marine worms and sponges different?
a.) Sponges live in mud, sand, or underneath rocks.
b.) Marine worms exist in more than one phylum.
c.) Marine worms are invertebrates.
Answer:
Segmented marine worms are easily identified by the many visible rings that make up their bodies. Many marine species are found on the sea bottom but are not restricted to it. Sponges are filter-feeding, colonial animals which live together as a larger unit. They appear to be plants but are in fact invertebrate animals. So the answer is (A.) I think.
Filter-feeding colonial organisms, sponges live as a single bigger group. Although they seem like plants, they are actually invertebrate animals. Thus, option A is correct.
What are the different features in worms and sponges?Bilateral symmetry describes how all worms have the same body on both sides. They lack scales and real limbs, even though they might have appendages like fins and bristles.
Each of them belongs to a different phylum, and each phylum is very diversified. They all have the trait of being primitive, basic biological creatures.
Segmented saltwater worms are easy to identify because of their body's many distinguishable rings. The sea floor is home to many marine creatures, but this is not the only place they may be found.
Therefore, Sponges live in mud, sand, or underneath rocks.

Monosaccharides and amino acids are both monomers. These monomers are formed by
hydrolysis. Which statement correctly identifies a difference in the structure of
monosaccharides and amino acids? *
A)Only amino acids contain cytosine, adenine, guanine, and thymine,
B)Only amino acids join together with peptide bonds to form proteins.
C)Only monosaccharides contain carbon and hydrogen.
Answer:
B: only amino acids join together with peptide bonds to form proteins.
Amino acids are glycine and leucine, which are composed of carbon, hydrogen, oxygen, and nitrogen. Carbon, hydrogen, and oxygen make up carbohydrates, which can be either little or big molecules, hence option B is correct.
What is the difference between monosaccharides and amino acids?
The building blocks that makeup proteins are polymeric molecules made up of a chain of amino acids. The biological role of galactose, mannose, fructose and ribose is also significant.
The most prevalent monosaccharide in living things is glucose, which also serves as a structural support system and an enzyme to catalyze chemical processes.
Therefore, the amino group of the additional amino acid creates a peptide bond with the polymer's carboxylic acid group, hence option B is correct.

At night, the concentration of carbon dioxide in the air in a forest is high. What is the main reason for this?
Answer:
The main reason the concentration of carbon dioxide in the air in a forest is high is due to the increase in plant growth.
Explanation:
Plants release carbon dioxide because of the process of respiration in which plants take in oxygen and give out carbon dioxide. During the day, carbon dioxide enters through the tree's pores, making oxygen escape (and is consistent with the “reverse lungs” concept).
On the other hand, at night, oxygen enters through the pores, and carbon dioxide escapes, rather than oxygen.
The main reason that the concentration of carbon dioxide in the air in a forest is high as there is only respiration going on at night and no photosynthesis.
What is plant respiration?While oxygen is needed for plant respiration, carbon dioxide is also released during the process. Plants, unlike people and other animals, don't have any specific structures for the exchange of gases, but they do have stomata (found in leaves) and lenticels (found in stems) that play a part in it. Compared to people and animals, leaves, stems, and plant roots breathe air slowly.
Respiration is distinct from breathing. Breathing is a phase in respiration that is completed by both humans and animals. Plants breathe differently through a process called cellular respiration, which they engage in throughout their whole existence since the plant cell needs the energy to survive.
Plants produce glucose molecules during this cellular respiration process by using photosynthesis to absorb solar energy and transform it into glucose. Several real-world experiments show that plants can breathe. To provide their cells the energy they need to function and stay alive, all plants breathe.
Therefore, only respiration occurring at night is the reason for a high concentration of carbon dioxide in the forest air at night.
