Answer:

Exercise is responsible for the increasing heart beat.

Explanation:

Exercise is responsible for the increasing heart beat because our body needs oxygen more faster during exercise. When we exercise our body needs quick energy and oxygen which can be provided by heart as well as the heart also removes carbondioxide which is produces during respiration process so the heart beat increases in order to provide energy and oxygen to the muscles.

Can anybody answer this
NARA [144]

Answer:

Options A, B, E, and F are correct

Explanation:

A). In the cell cycle, DNA replication is a process by which a duplicate DNA strand is produced with the help of replication machinery (enzymes, nucleotides, etc.). The overall process ensures that the newly developed strand is free of any mutations (errors) causing the production of wrong proteins at later stages. Although, there are chances of positive, negative or neutral mutations, the replication machinery aims to avoid any such errors at this stage.

B). DNA stores genetic information in the form of codes (known as codon) which needs to be translated in the form of proteins. This process is known as a transcription by which messenger RNA (mRNA) is produced in the nucleolus. Thereon, it is transported outside to encode proteins with the help of ribosomes. The process of copying genetic information on DNA in the form of mRNA is known is transcription.

E). The figure shown is also known as the central dogma of life. According to which, DNA (genetic information) is transcribed into RNA, which is then translated to proteins. In brief, RNA molecules brings the information from nucleous to ribosomes and make proteins. These proteins are often enzymes, hormones, and other biomolecules that perform the important functions in living organisms.

F). DNA and RNA are two types of nucleic acids responsible for all types of life on Earth. Since both of them are well recognized as nucleotides, they are made up of the same genetic building blocks known as nucleotides. Further, each nucleotide is comprised of a five-carbon sugar, a phosphate group, and a nitrogen base. The sequence of these nucleotides is responsible for the production of specific types of proteins.

Maslowich

Answer:

For a change in the environment that surrounds them.

Explanation:

Frogs and toads are amphibians that have the ability to live in both environments, that is why their respiratory system is highly adapted to extreme situations such as sudden climate changes, among others.

This modification of the environment many species would not tolerate because generally species always develop, live and reproduce in a single environment, such as humans, which is only in the terrestrial environment.

It is very difficult for frogs not to be able to adapt or survive climate change since they have the ability to adapt their respiratory system to two totally different media such as water and air.
