Answer:
This is an example of a <u>paraphyletic group</u>.
Explanation:
Paraphyletic groups is a group that contains only part of the descendants of a common ancestor. A group is constituted as paraphyletic when one or more holophyletic groups are subtracted from a clade (evolutionary branch). Traditional classifications are loaded with paraphyletic groups, such as invertebrates, pteridophytes, opposites. In each of these cases the group is defined by the exclusion of a smaller group within a larger one. An example is the reptiles are a paraphyletic group, since when we refer to them we are excluding mammals and birds even though they are taxa that evolutionarily descend from reptiles.
1) a) Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
Answer:
24 chromosomes.
Explanation:
The diploid number for a lily whose pollen contains 12 chromosomes would be 24 chromosomes and is produced when the pollen moves from a stamen to the stigma and fecundates the female gamete. Thus, a diploid cell, with 24 chromosomes (12 pairs, 12 x 2), is formed.
Gametes are haploid, it means, they contains half of the chromosomes.
Answer: True
Explanation:
Yes, they both fall at the same rate because the force of gravity is the same for both the cup and the water.
