Pollen....because cones are absent in angiosperms.....flowers are absent in gymno....and seeds are also absent in gymno sperm........so and is pollen !
Answer:
For the tRNA anticodon CCA the corresponding codon is GGU, which codes for the amino acid Glycine (Gly).
Explanation:
Transfer RNA or tRNA is responsible for driving the right amino acid into protein synthesis, once the mRNA codon has been translated by the ribosome. It is for that reason that each mRNA codon must have a complementary tRNA anticodon.
The RNA pairing rules is that each nitrogenous base has a complementary base, so:
- Adenine is complementary with uracil A=U
- Cytosine is complementary with Guanine C=G
In this case, it can be seen that:
- <em>For the anti-codon: CCA</em>
- <em>Codon: GGU</em>
- <em>Aminoacid: Gly</em>
Answer:
Environmental Science is an interdisciplinary course covering a wide variety of topics including biology, physics, geology, ecology, chemistry, geography, astronomy, meteorology, oceanography, and engineering. The course also considers ways in which human populations affect our planet and its processes. Of special emphasis is the concept of sustainability as a means of using resources in a way that ensures they will always be around us. The unifying concepts that tie the different areas of environmental science together are as follows:
Science provides a way to learn more about the world and influences how we understand it.
Energy conversions underlie all ecological processes.
The Earth is one interconnected system.
Humans change natural systems.
Environmental issues have a cultural and social context.
Human existence depends in part on increasing practices that will achieve sustainability
