The answer would be:
B. Sequence of the bases in DNA molecules.
Here is more about your questions:
DNA contain the instructions of the traits of an organism. Most of the organism have the same DNA but what makes each different is the sequence of the DNA. The sequence gives the instructions for the production of amino acid that will produce, which in turn determines what traits will be passed on or manifested by that individual.
Answer:
deuterostomes
Explanation:
During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.

Answer:
Reduce, Recycle, and Reuse.
Explanation:
Reduce your use of single-use, disposable, and non-biodegradable items. By doing that, you may be able to decrease the amount of waste you produce on a daily basis.
Recycle your items wherever possible. Separate your items depending on those that can actually be recycled, and those that may not. Before you throw something in the bin as trash, make sure to think about whether the item can be recycled in its entirety or perhaps a part of it can.
Reuse your items as much as possible before you end up replacing them. Only buy essential necessities and choose your products wisely (preferably those with less packaging). Always look for items in your surrounding that can be reused.
Those three ways are very crucial when it comes to achieving sustainable living. At the same time, it helps humans reduce the amount of waste released into the environment.
hope this helps!! p.s. i really need brainliest :)
