Answer:
A) The male stamens hold the pollen, the female pistil holds the ovule, and the petals attract pollinators.

Stamens (male reproductive parts of a flower) collectively forms the male reproductive organ (androecium) in a flower whereas pistil (the female reproductive part of a flower) forms the female reproductive organ called gynoecium.

Stamen consists two parts that are anther (that produces pollens, male reproductive cells) and a stalk like structure called filament, which supports/ holds pollen producing anther.
The female pistil holds the ovule that is enclosed by ovary in flowering plants (angiosperms) and the petals in a flower attract pollinators.

Thus, option A) is the right answer.

In clover plants, the pattern on the leaves is determined by a single gene with multiple alleles that are related in a dominance
igomit [66]

Answer:

The correct answer is -

a. 7

b. 7 (p1p1, p1p2, p1p3, p1p4, p1p5, etc

c. p7 is abundant

Explanation:

According the question the dominance of the big leaves is p7 > p6 >p5 >p4 >p3 >p2 >p1 where 1 represent least dominance and 7 represent most dominance  

let represent the phenotype with the numbers 1 to 7 and genotype with a combination of these numbers so the genotype in respect of phenotype would be :

p7p7,p7p6, p7p5, p7p4, p7p3, p7p2, p7p1 - most dominant 7

p6p6, p6p5, p6p4, p6p3, p6p2, p6p1 - 6

p5p5, p5p4, p5p3, p5p2, p5p1 - 5

p4p4, p4p3, p4p2, p4p1 - 4

p3p3, p3p2, p3p1 - 3

p2p2, p2p1 - 2

p1p1- 1 least dominant

Thus, there are 28 different combinations or patterns of genotypes. 7 phenotypes patterns.

After an open reduction and internal fixation of a fractured hip, the nurse is helping a client to get out of bed into a chair.
PIT_PIT [208]
<span>I think the answer would be: instruct the client to bear most of the weight on the unaffected leg and pivot to the chair.
</span>
Hip is a complex and thin bone. Repairing it will be harder than big bones and it will be easier to break again. The client should try to not burden the fractured bone to reduce the risk. At least you need to give the bone time to heal themselves.
