Answer:
Option B, Mammals and reptiles in the post-dinosaur age.
Explanation:
Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.
Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.
Hence, option B is correct
Answer: O polar covalent bonds because oxygen is more electronegative than hydrogen
Explanation:
In the water molecule the two hydrogen atoms and one oxygen atoms forms the chemical structure in this the covalent bond is formed between hydrogen and oxygen and this is formed due to sharing of electrons between hydrogen and oxygen and oxygen being electronegative requires two electrons to complete its valency which are provided by two electrons each from one hydrogen and the O polar covalent bond is formed by this way.
Answer:
*So I'm guessing you mean the reproduction of plants*
Bees and other insects such as butterflies and moths.
Bats also help pollinate as well in desert and tropical environments, as well as birds.
Plant reproduction could also occur if an animal eats the fruit of a plant, and proceeds to live its life, then pass (poop out) the seeds much farther from the original location of the parent plant.
Answer:
46 chromosomes
Explanation:
<em>I. G1 phase (Gap 1) - Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis) - Each of the 46 chromosomes is duplicated by the cell.</em>
B, C, D
Meiosis is for sexual reproduction and is meant to create diversity. Answers A/e involve identical-ness, so they are wrong.
