<span>Comparative embryology is the study which determines the organisms that have the same and almost identical embryo development.

While, comparative morphology is the scientific study of organisms where their structures, physical entities and elements are identified to be similar or dissimilar. Using only simple basis of empirical observation, a scientist can detect whether two animals are of the same family or not.</span>
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.
The organs - Kidneys, Ureters, Bladder, Urethra, Sphincter muscles, and nerves- filters waste from the bloodstream and removes the waste from the body. Your kidneys circulate blood and separate waste, so it can be released. <span />
Black color (B) and practising gait (t) horse has a genotype BBtt
Chestnut color (b) and trotting gait (T) horse has a genotype bbTT
<span>Crossing BBtt x bbTT
</span> <span>The genotype of the offspring is going to be
BbTt, which means that the phenotype is black color and trotting gait horse.</span>
