1. a sequence of sugars, phosphates, and nitrogenous organic bases 2. a complex molecule containing the genetic code

3. a nucleic acid that participates in the synthesis of proteins

DNA
nucleic acid
RNA

Answers

Answer is Nucleic Acid

Reasoning - Because phosphate, sugar, nitrogenous make up the Acid !!! lol RNA is synthesis of protein. DNA is the control of genetics which is obvious.

Answer:

1: Nucleic acid;   2: DNA ;   3: RNA

Explanation:

Nucleic acid is a sequence of sugars, phosphates, and nitrogenous organic bases. Examples of nucleic acid are DNA and RNA. DNA is a complex molecule containing the genetic code. Transcription of DNA forms mRNA which in turn serve as template for protein synthesis. RNA is a nucleic acid that participates in the synthesis of proteins.

Answers

Answer:

This is an example of a symbiotic relationship.

Explanation:

A symbiotic relationship is a close, prolonged association between two or more organisms of different species that normally benefits both members. A good example of symbiotic relationship is a coral and algae, bacteria in the human gut etc

From the information provided, the algae perform photosynthesis, providing the coral with nutrients for feeding and help with calcification. In return, the coral provide the algae with nutrients for it's growth.

Which gas is most important for understanding atmospheric processes? carbon dioxide oxygen water vapor ozone

Answers

Answer:

Water wapor is the most important gas for understanding atmospheric processes

Explanation:

To understand this you have to know that we have atmospherics processes such as radiation, aeroesol movement (this one is important to the process related with water cycles and energy) and convection.  Water vapor plays an important role, this because transports latent heat also can condense into clouds and clouds reflects and adsorb solar radiation and affects earth's energy cycle, after that water vapor can be blown by the wind and return to the earth as snow or rain. Another process that is involved is that the heat radiated from the earth's surface is absorbed by the molecules of water vapor and they radiate heat in all directions. Finally water vapor is considered the second source of warmth to the earth.

Gases that trap heat in the atmosphere; these include water vapor, carbon dioxide, methane and ozone.

In addition to seeds, which of the following characteristics are unique to the seed-producing plants? A) sporopollenin
B) lignin present in cell walls
C) pollen
D) use of air currents as a dispersal agent
E) megaphylls

Answers

Plants produce seeds that develop into new plants. This process occurs through the dispersal method that involves the movement of their seeds by wind, water, animals, fire, and explosion.

In seed-producing plants, the following characteristics are exhibited:

  • Inside the seed is a partially developed plant that lands in a favorable area, get sprouted, and begins to grow.
  • It requires light, water, and nutrients to grow.
  • Wind disperses lightweight seeds like maples trees and dandelions.
  • Pollen delivers the sperm cells near the egg and the process of fertilization occurs to develop seeds.

Thus, we can conclude that in addition to seeds, the unique characteristic of the seed-producing plant is pollen. Hence, option C is the correct answer.

Describe why estimating the age of the Sun can give an approximate age of the Earth.

Answers

The sun is a main source on providing life on earth. So if it were to be estimated it would be the same as the earth's life span because when the sun was born life on earth was also born simultaneously. 
Since the planets formed not too longer than the sun, just use the sun's estimate, then see how far you could go back in history to see how old the sun is and compare it to Earth's since the age is not too far apart. "not a real answer just trying to help"
