Answer:
possible genotypes are - Rr Rr Rr Rr
Possible phenotypes - remember that R is dominant therefore all of the seeds with be round
Explanation:
Answer:
plasma membrane, ribosomes...
Explanation:
Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm and DNA... The cytoplasm is all the contents of the cell inside the cell membrane, not including the nucleus.
Protons- these have a positive charge
Electrons-negative charge
Neutrons- neutral charge
Answer:
Ecosystem
Explanation:
The ecosystem includes a total of the abiotic and biotic components of a region. These components interact with each other and make the ecosystem self-sufficient in terms of energy and nutrients. Climatic conditions, physical factors, soil type, and its feature together make the non-living or abiotic part of an ecosystem. They interact among themselves and with the living components by nutrient cycling. All the species of living beings together make the biotic components of an ecosystem. They interact with each other by food chains and food webs.
Oceans are an example of the aquatic ecosystem while deserts are terrestrial ecosystems.
Answer:
In a diploid zygote, the cause of trisomy is two sister chromatids remain joined during meiosis II (option B).
Explanation:
At the end of meiosis I, each daughter cell contains a chromosome formed by sister chromatids, each of which must be separated in meiosis II to form the gametes with a chromosome charge equivalent to half the chromosome charge of the species.
The result of the sister chromatids not separating in meiosis II -by not disjunction- results in a gamete with an extra chromosome, which when joined to another gamete results in a zygote with an additional chromosome, which is considered an aneuploidy, called trisomy.
