What biomolecule determines whether an individual inherits the inability to produce the enzyme needed to break down the amino acids
Answer:
NUCLEIC ACIDS
Explanation:
Four biomolecules are found in living systems and they are responsible for every process undergone by cells of living organisms. Nucleic acid is one of the four biomolecules, which is the precursor of another biomolecule called PROTEIN.
DNA and RNA are the two nucleic acids which contains segments called GENES that encodes the information needed for the synthesis of proteins and transfer of this information to offsprings. Genes found on nucleic acid biomolecules undergo expression to produce proteins. ENZYMES are proteinous molecules that catalyse biochemical reactions in living systems.
From the explanation above, this means that ENZYMES that catalyze reactions like breaking down amino acids are PROTEINS, which in turn are made from GENES carried by NUCLEIC ACID biomolecules.
Therefore, NUCLEIC ACIDS determine whether an individual inherits the inability to produce the enzyme needed to break down the amino acids

B ( or D but I'd say B )
Explanation:
I may so think its B because If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.

C
(look at picture)
The second structure shows the structure of carbon atom because atomic number of carbon is 6. Therefore, option B is correct.
What is carbon atom ?The carbon is an element denoted by symbol "C". The atomic number of carbon is 6. It belongs to the 14th period in the periodic table. Carbon is a nonmetal and the shape of carbon is tetravalent, so it has 4 electrons in the valence shell.
Carbon atom available in many forms, including carbon dioxide, coal, a cow, sugar and diamond. Carbon forms covalent bonds with atoms of carbon or other elements because it has 4 electrons in the valence shell.
In the second structure we see that there are four electrons are preset in valence shell ad the total number of electron present is six. Therefore, the second structure shows the carbon atom.

I literally don’t know the answer to this Someone plz help
Answer:
Abiotic conditions would be the temperature of the reef, and also the amount of light that the living organisms receive. (aka coral and zooxanthealle algae)
Biotic would be coral, and also fish. A disturbance in the balance of an abiotic of biotic factor could in turn kill one of the many organisms needed to keep each other alive in symbiosis within the coral reef. In a domino effect, if one organism that is essential to the balance dies, then another, and so on until the coral reef itself dies.

Which of the following is the most direct evidence for evolution?
A. Biogeography.
B. Anatomy.
C. Developmental biology.
D. Fossil record.
Answer:
D. Fossil record.
Explanation:
The fossil record evidences the evolutionary history of life on Earth by tracing the life forms that existed from earlier geological times and remained in the sedimentary rock. Different fossils were dated in the sedimentary rocks of all geological periods. The simplest forms of life were discovered in the oldest rocks, while more complex fossil organisms were found in the newest rocks. In consequence, the fossil record can support the evolutionary process as proposed by Charles Darwin, who indicated that the simplest forms of life evolved in more complex organisms.

Answer:
Phylum Arthropoda
Explanation:
despite being very different of diets that include different types of food containing different levels of biomolecules, these diets are all able to support human being in living. How is this possible?
Answer:
As nutrients, protein is overemphasized and carbohydrates are underrated in terms of their importance in our diets. Most people in the United States now eat more protein than their bodies need, and, somehow, carbohydrate-rich foods such as potatoes and bread have gotten a bad name for being fattening. Yet protein from animal sources often comes in foods that contain significant amounts of saturated fatty acids. And the only carbohydrate-rich foods that are truly fattening are those laden with fats and added sugar, such as pastries, cookies, and baked potatoes heaped with sour cream.
In fact, there is some evidence that diets high in carbohydrates may help reduce the risk of heart disease. Thus the Eat for Life guidelines suggest not to eat any more protein than you already do and to increase the amount of carbohydrates you eat to compensate for the lower amount of fat that your diet will contain.
This chapter presents the evidence that increasing the proportion of carbohydrates in the usual American eating pattern at the expense of fat will tend to lower chronic disease risk. It also discusses some of the health claims made for dietary fiber, a group of substances that are made up mostly of complex carbohydrates.

Explanation:
d. Bogs are characterized by acidic groundwater.
What is a bog?
"A bog is a wetland of soft, spongy ground consisting mainly of partially decayed plant matter called peat."
What are characteristics of bogs?
"Bogs are characterized by spongy peat deposits, acidic waters and a floor covered by a thick carpet of sphagnum moss. Bogs receive all or most of their water from precipitation rather than from runoff, groundwater or streams."
How were bogs formed?
"Once plants began to decompose at the edge of a lake and once conditions were right for peat fen to form, the lakes slowly started to reduce in size. The fen continued to grow and over time a raised bog habitat began to form. The only water that is supplied to a raised bog is rainwater which is very low in nutrients."
