Why can dna be matched to the person it came from
AlekseyPX

Answer:

Since every person inherited DNA from their parents, who inherited it from their parents, and so on, a person's DNA is made up of the DNA of their ancestors. If you and another person both have the same ancestor, there's a chance that you both inherited some of the same DNA.

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cel
Leviafan [203]

Answer:

large central vacuole

cell wall

Explanation:

Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.

Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.

Serggg [28]
The correct answer is natural selection. C is the answer!

Bacteria has a stronger resistance that usually produces even more resistant bacteria, and the cycle just repeats itself, making more and more resistant bacteria. This process is called Natural Selection.
