Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
Answer:
Blastocyst,Blastoderm
Explanation:
The blastula is made up of a hollow spherical layer of cells, referred to as the blastoderm which surrounds a yolk or fluid-filled space called the blastocele or blastocoel. In most mammals, including humans, the structure formed next is the blastocyst, a mass of inner cells that are distinct from the blastula
The answer is B . Hope this helps
Answer:
The answer is B, extensive research of an individual organism over many years.
Explanation:
The question is asking, what best describes Darwin's studies that led to the theory of evolution, it would be a lot of research over a long period of time. Think, if you were to do a school project, would you get your best results over a short or long period of time with little or a lot of evidence/research? So, B is the best answer, I believe.

Answer:
Forestation.
Explanation:
When life is created on land where there originally was no life, wind brings over pioneer species, such as grasses. Over time, life takes advantage and grows bushes, trees, and so on.
