Answer:
Because those chemical reactions help the cell to dispose useless substance after they are used and synthetize substance they need or the body needs through them.
Explanation:
Hello.
In this case, since the overall processes inside the cell are constantly producing and getting rid of several substances such as nutrients, proteins, lipids and other, we can say that decomposition reactions serve as a mechanism that the cell uses in order to obtain energy or dispose a substance that is no longer important for it. Moreover, since the cell is the fundamental part wherein the most of the useful substances the body needs are synthetized, we can infer that synthesis reactions must occur in order to allow the body to perform lots of functions, for instance, proteins associated to the hair or nails growing are synthetized inside the cell via the protein synthesis mechanism.
Best regards.
I'm pretty sure the answer is B. Invest in alternative energy sources that do not burn fossil fuels. The reason I would pick B is because in Antarctica the ice is melting more and more over time because, cars and factors etc are burning fuels which result in more damage to the ozone layer.
Answer:
This diagram depicts the phenomenon of DNA translation in the central dogma of life. Here are the labels
1. <u>RNA strand</u> because it is a sequence of four nucleotide A, G, C, U. It has Uracil, this is why it is RNA. Further, translation takes place when DNA is already transcribed.
2. <u>Ribosome</u> is a machinary for protein formation. This is because it provides right environment to transfer RNA to decode RNA strand into a protein sequence.
3. <u>Amino acid</u>: Each amino acid is carried by a transfer RNA (tRNA). The type of amino acid depends on type of tRNA. All proteins are mostly formed with 20 amino acids and so there are at least 20 tRNA.
4. <u>Polypeptide (protein) chain made up of amino acids</u>: It depicts multiple amino acids, which tRNA carries, and are bonded together through peptide bonds.
5. <u>Transfer RNA (tRNA)</u>: tRNA has a complementary sequence to RNA strand and thus it binds with right sequence. It carry an amino acid which is then bonded to another amino acid amino acid to make a polypeptide chain.
