Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino a
vampirchik [111]

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).

Novosadov [1.4K]

Answer: b. Webbed-toed mice survived better and reproduced more than mice without webbed toes.

Explanation:

Natural selection is a phenomenon that suggests that organisms that have a better structural and morphological advantage over the others have better chances of survival over the others.

The webbed toed mice have a survival advantage over the without the webbed toes because this can help the webbed toed mice to swim. The webbed toed trait will be beneficial and passed on to the next generation of the mice and the webbed toed mice will reproduce more than the mice without webbed toes.

11) In a typical energy pyramid about 10% of the available energy is transferred from one trophic level to the next. Consider an
crimeas [40]

Answer: Option B

Explanation:

In a typical energy pyramid the amount of energy that is being transferred is only 10% rest of the energy is lost in the form of heat.

The energy from the sun is converted in the form of chemical energy which is stored in the producers.

10 per cent of this energy is transferred to the next trophic level and rest of the energy is lost in the form of heat. This goes on, there is only a transfer of 10 % energy from the successive levels.

So, if the producers have 200 Kcal/m2/year energy the the primary consumers will have 10% of this energy which is equivalent to 20 Kcal/m2/year and then the secondary consumers will have 10 % of 20 Kcal/m2/year which is equivalent to 2 Kcal/m2/year.
