Answer:
natural selection
Explanation:
Darwin proposed <u>natural selection</u> as the process that causes evolution.
According to the theory of natural selection, the environment naturally selects for genes that confer fitness to organisms over every other gene. In other words, organisms that are able to adapt to an environment survive and contribute more to the subsequent generation while those that are poorly adapted contribute less and gradually fade away from the population.
<em>For example, when a drug is taken a particular pathogen, the susceptible ones among the pathogen's population will die off while the ones with the resistance gene survive, reproduce, and pass on the resistance gene to the subsequent generation. Consequently, the same drug might not work at all for the new generations of the pathogen because the gene that confers fitness has been selected for.</em>
Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.
So..the answer should be D. Eukaryotic cells have a true membrane-bound nucleus and prokaryotes do not
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
So..it can't be C. or A. or even B.
Correct me if I'm wrong.
Viruses are smaller then Bacteria, Viruses require living hosts.
Infections caused by bacteria include:
Strep throat
Tuberculosis
Urinary tract infections
Answer:
A:T;G:C
Explanation:
adenine goes with thymine unless it's mRNA and it will go with uracil. guanine and cytosine always go together.
I think the correct answer from the choices listed above is option A. The first type of cell to differentiate is a neuron. The neurons are cells that process and transmits information through electrical and chemical signals. Hope this answers the question.
