Homeostasis is a property of an organism or system that allows its to maintain the controlled parameters within normal ranges. Henry Barbour contributed to the understanding of this concept by his delineation of the reactions of the temperature of the body. This is in line with the same concept that was initially proposed by Claude Bernard.

In 1885, Claude Bernard’s gave the concept of physiologically constant internal environment. He was the first to give stress on the importance of biological regulation of the “milieu interieur”. In 1912, Henry Barbour (a student of Yale University) was successful in finding that hypothalamus, which is a structure in the brain has the ability to thermoregulation.

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).

Write a paragraph of 150 words on the subject ‘different ways to protect ozone layer and prevent emission of hazardous gases’ fo

bogdanovich [222]

Answer:

There are a few different steps we can take to protect the ozone layer. As you know, the ozone layer is the layer that protects us from the sun’s powerful UV rays and it also protects us from other harmful things roaming in space. The first thing we can do to protect the ozone layer is reduce the use of natural gases. The gases produced from the natural gases had torn holes in the ozone layer. A way to prevent emissions of hazardous gases Is to switch to renewable energy. Renewable energy is not only easier to access and replace, solar panels and wind energy dont give off harsh and hazardous gases that mess with the ozone layer and the climate.

Explain the differences in the three types of RNA by connecting it to a factory.

kykrilka [37]

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled .

RNA carries genetic information from the nucleus to ribosomes for the synthesis of proteins; while tRNA carries specific amino acids to the ribosomes to assist the protein biosynthesis, and on the other hand, rRNA provides the structural framework for the formation of ribosomes.
