<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.
Scientists use biotechnology to create all of the following except waste products. The correct answer is D.
The correct answer is - Theory of the Ekman spiral
V. W. Ekman or Vagn Walfrid Ekman was a Swedish physical oceanographer. He is famous for his studies of the dynamics of ocean currents. Ekman developed a theory called as the “theory of the Ekman spiral”. This theory explains maintaining balance between frictional effects in the ocean and the Coriolis force. The force arises from moving objects in a rotating environment such as planetary rotation.
Answer:
Bad mutation: deletion/addition mutation
Good mutation: silent mutation
Explanation:
Addition or deletion mutation results in the reading frame of codons to be changed, leading to a extensive missense mutation that will lead to a non-functional protein product to form.
Good mutation are silent mutations that leads to no change to the final product but causes codons to change in sequence. This increases genetic diversity in the gene pool that enables the species to be more resilient to environmental changes.
