Explanation:

Both strands of the DNA double helix contain nitrogenous bases held together by hydrogen bonds. In DNA, the sequence of nitrogenous bases varies widely. What is the significance of the nitrogenous bases?

A. They determine the amino acids in the proteins synthesized.
B. They prevent mutations from occurring in the process of DNA replication
C. They help complete the sugar-phosphate backbone of DNA molecules.
D. The amount of adenine and cytosine determines the length of the gene on a DNA molecule.

Answers

Answer:

A

Explanation:

Essentially, in the process of protein synthesis, there is first transcription where mRNA is synthesized off of a DNA strand with complementary nitrogenous bases. After processing occurs (in basic terms the mRNA is literally processed) and the mRNA strand leaves the nucleus, it attaches to a large and small ribosomal subunit (a ribosome) where translation occurs. The gist of it is when the mRNA strand is being read by the ribosome. tRNA will come over and bind temporarily bringing with it a specific amino acid, starting the formation of the polypeptide/amino acid chain. Nitrogenous bases play into this as the sequence of the nitrogenous bases is what determines what tRNA will bind onto it which determines which amino acid is brought. More specifically, this deals with the codons of the mRNA and the corresponding anticodons with the tRNA, which is a bit of a more specific topic.

The nitrogenous bases help complete the sugar-phosphate backbone of DNA molecules. The correct option is C.

What is DNA?

DNA, also renowned as deoxyribonucleic acid, is a complex molecule that includes all of the information required to construct and retain a lifeform.

DNA is found in the cells of all living things. In real sense, as in almost every cell in a multicellular organism contains the entirety of the organism's DNA.

DNA is composed of chemical key components known as nucleotides. These building blocks are composed of three components: a phosphate group, a sugar group, and one of four different types of nitrogen bases.

Nucleotides are linked together in chains, with the phosphate and sugar groups alternating.

Thus, the correct option is C.

i. All organisms are made of organelles / cells.

ii. All existing cells are produced by other living / dead cells.

iii. The atom / cell is the most basic unit of life.

ii. All existing cells are produced by other living cells.

iii. The cell is the most basic unit of life.

7. Cell theory is one of the great unifying theories of biology

Explanation:

Cell theory is one of the central theories of biology and is universally accepted. It states that all organisms are cellular - that is they are made of cells. It also states that all living things come from other living cells (not spontaneously, or from dead cells). The cell is the most basic unit of life, organisms can be unicellular, but no living thing is 'less' than that.

Which answer best explains how most scientists think that planets form? A. Large chunks of matter break off a star that collides with another star; these chunks then become planets orbiting the star. B. Large chunks of matter break off a planet that collides with a smaller body; these chunks gradually clump together to become a new planet. C. A rotating cloud of space dust and gases begins to flatten and condense, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets. D. A rotating cloud of space dust and gases begins to condense, forming a protoplanet; if the protoplanet is massive enough, its gravity will attract nearby matter until the protoplanet becomes large and round enough to be considered a planet.

Answers

Answer: B

Explanation:

Thats what the teacher told me

The scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."

What is the nebular hypothesis?

The nebular hypothesis is the most widely accepted scientific theory for the planetary systems, such that the solar system and, as per this theory, a cloud of gas and dust, called a nebula, collapse due to gravitational forces; the nebula contracts, and it rotates faster, flattening into a disk, which eventually cools and condenses, forming a protoplanetary disk.

Hence, the scientists believe that planets form when a rotating cloud of space dust and gases flattens and condenses, forming a new star; the remaining matter forms an accretionary disc around the star, gradually coalescing to form planets, as described in Option C, also known as the "nebular hypothesis."

Which letter marks the zone of inhibition?

Answers

Answer:

A. B

Explanation:

"B" as labelled in the above is the zone of inhibition.

The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.

At the Point B, microbes can not grow in there; they are inhibited.

In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.

what are catabolic reactions

Answers

Answer:

which complex molecules are broken down to simpler components, are classified as catabolic reactions. Taken as a group of reactions within a cell or even an organism, they can be referred to as the cell's or organism's anabolism or catabolism.

Explanation:

Catabolic reactions are a type of metabolic reaction that take place within a cell. Larger molecules are separated to form smaller molecules, as in the case of respiration where glucose is broken down to form carbon dioxide and water. Often they are hydrolysis reactions in which water molecules are used to break bonds.

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?

This shows that the distinctions between people living in a culture or geographical region are often based on ethnicity including ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair color, body potential for heat resistance, and menu variety. In something like a specific race or ethnic group, these social traits bring them alongside, and the young government associated with a particular race is often obligated to answer the custom practiced by individuals related to such a particular demographic. These are assumed that understand the connection to a specific community follow these rituals only to solve difficulties they have previously faced due to errors perpetrated by certain ancestors.
