Which of the following is an example of radiation?
drek231 [11]

Answer: D. Our atmosphere is constantly being heated by the sun.

Radiation is the transmission of energy in the form of waves or particles released by one source and absorbed by another source. Types of radiations includes electromagnetic radiation, particle radiation, acoustic radiations and gravitational radiations.

Our atmosphere is constantly being heated by the sun is the example of the radiation because the sun radiates energy in all directions in the form of heat, light and radiations. Solar energy in the form of radiation is either reflected back to the sun or it is absorbed by the earth atmosphere. Therefore, this causes heating up of the earth atmosphere.

This is a molecule of glucose, a simple carbohydrate. If this molecule were broken down, would it provide all of the elements ne
Bingel [31]

No, it wouldn't provide all the elements needed to assemble lipids, nucleic acids or proteins.

As in the diagram, the breakdown of glucose molecules will release hydrogen, carbon and oxygen.

As we know that Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON).

Biomolecules contain elements like carbon, nitrogen, hydrogen, oxygen, sulfur, and phosphorus. Among these  carbon, nitrogen and hydrogen are  found in all biomolecules. Hydrolysis reactions use water to breakdown polymers into monomers, Hydrolysis reactions break bonds and release energy.

As a final exam question in your biology course, you are asked to identify an animal that you immediately recognize as a chordat
julia-pushkina [17]

Answer: c) and b) are correct.

The brain is encased in a protective bony or cartilaginous housing in craniates.

The anterior end of the nerve cord is elaborated to form a brain in craniates.

Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics. The last one does not apply as a specific feature because the tunicate have neural crest but are not recognized as craniata.

why would shuffling genetic material to produce new combinations of characteristics be advantageous to a species?
Radda [10]

Answer:

Suffling of genetic material increases genetic variation in offspring which is important for evolution.

Explanation:

Genetic shuffling or genetic recombination helps in the formation of new trait combinations which increase the genetic variation in the population and this genetic variation is very much important for the evolution of species.

In sexual reproduction, the genetic shuffling occurs during the formation of gametes when the two homologous chromosomes exchange their genetic material with each other. This increase variation in gametes.

Fusion of two different gametes in sexual reproduction also helps in increasing the genetic variation in the offspring.
