<span>Similarities</span> between Gymnospermes and Angiospermes:
<span>·
</span>Having seed-Gymnospermes and Angiospermes are types of plants bear seeds. They belong
to a single class known as Spermatophyta. Spermatophyta or seed
plants are those <span>plants that produce seeds.</span>
<span>·
</span>Diferentiation- The sporophyte (diploid
multicellular stage in the life cycle of a plant) of both,<span> Gymnospermes and Angiospermes,</span> is differentiated into root, stem, and leaves.
Differences between Gymnospermes and Angiospermes:
<span>·
</span>Seed-Although both
have seeds, differences between them are huge. Gymnospermes have bare, non-encased seeds. The term
"gymnosperm" in Greek means "naked seeds".
On the other hand, seeds of Angiospermes are enclosed within an ovary,
usually in a fruit.
<span>·
</span>Pollination- In Gymnospermes, the pollination is
by wind, unlike most Angiosperms, who use insects, mammals or birds. Gymnosperm flowers are often difficult to spot
because they are not out to attract flying pollinators.
Answer:The main features of a nauplius are a simple, unsegmented body, three pairs of appendages (antennules, antennae, and mandibles), and a single, simple, “naupliar” eye. Nauplius larvae are found in the life cycles of cirripedes, ostracods, branchiopods, copepods, euphausiids, the decapod peneid prawns, and….

Explanation:
This question is regarding a gene in rabbit coding for fur color. Brown fur (B) in rabbits is dominant over white fur (b). However, according to the question, a white female gives birth to all white rabbits, even though the father had brown fur. This is possible because the father is heterozygous for the brown fur i.e Bb.
Hence, in a cross between a heterozygous father (Bb) and a white mother (bb), the following gametes will be produced by the following parent:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the probability of 1/2 of the offsprings will possess white fur (bb). Based on this result, the white female is able to give birth to all white rabbits because the male rabbit contributed the white allele (b).
