Which two macromolecules contain nitrogen?

Biology
2 answers:
AlexFokin [52]3 years ago
5 0

There are four classes of macromolecules (polysaccharides or carbohydrates, triglycerides or lipids, polypeptides or proteins, and nucleic acids such as DNA & RNA). Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).

Answer:

Proteins and nucleic acids

Explanation:

Proteins are the polymers of amino acids. Each amino acid has one central carbon atom to which four functional groups are attached: amino group, carboxyl group, hydrogen atom and side chain.

Nucleic acids (DNA and RNA) are polymers of nucleotides each of which consists of pentose sugar, phosphate molecule and one nitrogenous base (adenine, guanine, cytosine, uracil and thymine).

Hence, amino acids and nitrogenous bases of proteins and nucleic acids contain nitrogen.

Match each example of a conflict with what it tells you about the character invloed
OLEGan [10]

An example of a conflict is that Beverly is going to make Millicent's challenge extra tough: she seems to enjoy treating people badly.

<h3>What is a conflict?</h3>

A conflict simply refers to any form of disagreement, misunderstanding, or struggle that arises between two (2) or more parties, especially due to any of the following reasons;

  • Differing opinions
  • Incompatibility
  • A difficult challenge.
  • Opposing view
  • Superiority

Some examples of a conflict with what it tells about the character include the following:

  • Beverly is going to make Millicent's challenge extra tough: she seems to enjoy treating people badly.
  • Tracy is rejected by the sorority because of the way she appears: she doesn't look and act like the people who are popular.
  • Millicent is unwilling to abandon her old friend Tracy: she thinks being a good friend is more important than being popular.
  • Millicent is starting to question being in a group: she takes time to think things though carefully.

The volume and mass of the brain has increased about threefold from early human ancestors such as Australopithecus afarensis, to
spin [16.1K]

The question is incomplete as it does not have the options which are:

A. The threefold change happened in one concentrated burst.

B. The change was not consistent in direction, but happened in multiple bursts concentrated at each speciation event.

C. There was consistent directional selection toward a larger brain all along the lineage between the two species.

D. None of the above.

Answer:

Option-B

Explanation:

The hominids evolved with time and the known hominid in modern time is the Homo sapiens or modern human.

The Homo sapiens like other species could have evolved from the older species through speciation and studies suggest that one of the major factors of human evolution is the size of the brain.

Two possibilities could explain the size of the brain that it could have evolved slowly with time called the gradual equilibrium or in bursts concentrated at each speciation event.

Since the punctuated equilibrium takes place in bursts until the species reach stasis is the most applicable condition for punctuated equilibrium to happen therefore Option-B is the correct answer.

A cell is placed in a solution that is hypotonic to the cell. Which of the following best describes movement of water in this si
Lera25 [3.4K]

Answer:

C. Water will flow into and out of the cell, but the overall net movement will be into the cell.

Explanation:

In a hypotonic solution, the concentration of water outside the cell is higher than inside the cell and the concentration of the solute is lower than inside the cell, therefore, water will flow in and out of the cell but the net movement of water will be from area having higher water concentration to lower concentration.

That means the net movement of water will be into the cell if a cell is placed into the hypotonic solution. Water moves in and out of a cell by the process called osmosis which is a type of diffusion.

This movement of water into the cell will swell cell and the cell can burst if it is not protected by a cell wall. Therefore the right answer is C.
