Answer:
D. In autopolyploidy, one parental species contributes to the polyploidy; in allopolyploidy, two parental species contribute to the polyploidy.
Explanation:
Autopolyploidy is the polyploidy that arises when the organisms have more than two complete sets of the same genome. For example, if a diploid species is represented as "AA", its autopolyploid with four complete sets of the genome can be represented as "AAAA".
On the other hand, allopolyploidy occurs when the polyploid carries more than two complete sets of the genome from separate species. For example, if two diploid species are represented as "AA" and "BB", their allopolyploid with four complete sets of the genome can be represented as "AABB".
Answer:
Plate movements may change the shape of Earth's surface and cause geologic events such as earthquakes.
Explanation:
A ribosome<span> is a cell organelle. ... </span>Ribosomes<span> are found 'free' in the </span>cytoplasm<span> or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million </span>ribosomes<span>. Several </span>ribosomes<span> can be attached to the same mRNA strand, this structure is called a polysome.
</span>Ribosomal<span> protein synthesis in eukaryotes is a major metabolic activity. It </span>occurs<span>, like most protein synthesis, in the </span>cytoplasm<span> just outside the nucleus. Individual </span>ribosomal <span>proteins are synthesized and imported into the nucleus through nuclear pores.</span>
