Mitosis and meiosis are processes by which animal and plant cells divide. which statement best describes a difference between mitosis and meiosis?

D. Mitosis produces genetically identical daughter cells

Correct answer is D

Below are the choices to choose from for an

A. Meiosis is a multi-step process.

B. Mitosis occurs only in eukaryotic cells.

C. Meiosis is used in the repair of an organism.

D. Mitosis produces genetically identical daughter cells

Explanation:

A. Both meiosis and mitosis are multi -step processes.

B. Mitosis also takes place in prokaryotic cells.

C. Meiosis generates gametes used in sexual reproduction.

D. (correct): Cells produced through mitosis contain DNA identical to the parent cells, whereas those produced in meiosis produces cells that are are unidentical.

Mitosis and meiosis are both processes which describe the production of new cells. Mitosis is responsible for producing 2produces 2genetically identical daughter cells . Meiosis on the other side produces 4 unidentical daughter cells, they are different from each other and the parents and they have half number of chromosomes (haploid)

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.
