Hi.
All answers except B are correct.
When living things exhale, we release carbon dioxide. Producers use photosynthesis to make food & oxygen - using carbon dioxide.

It is regularly hard to separate the elements of the apprehensive and endocrine system since it is hard to separate between the anxious and endocrine systems since a few neurons emit hormones and some endocrine organs react to neural signs.
The endocrine system is not a piece of the nervous system, but rather it is as yet basic to correspondence all through the body. This system is made out of organs, which emit concoction ambassadors known as hormones.
The temperature is lowest at the crust. As you get lower into the Earth's surface, the temperature gets hotter.
Answer:
Mutation is the changing of the structure of genes resulting in a varied form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
A silent mutation is a mutation where the codon still corresponds to the same amino acid. The sequence of amino acids is not changed so the protein that gets made is the same as the wild type, or normal protein.
A missense mutation changes the codon so that it codes for a different amino acid.
Finally, a nonsense mutation causes protein creation to stop early, which makes a non-functioning protein.
Substitution means that one base is exchanged for another. This is kinda like having a substitute teacher. The sub isn't your normal teacher, but they are still a teacher. A protein that is made with a substitution might still function normally, or it could be nonfunctional.
Deletion is kinda self-explanatory. It happens when a base is deleted or, in other words, is just missing.
Finally, insertion means an extra nucleotide is added.
Explanation:
Hope it helps .
