When I was 4 years old my brother was half of my age now I'm 20 years old how old is my brother?

Answers

Answer 1

My brother is 18 years of age.

The question implies that the brother's age will be 2 years younger, hence he will be 18.

When I was 4 years old, my brother was 2 years old. (It is given that my brother is half my age at that time.)

Now, I am 20 years old. That means there is a gap of 2 years between now and then.

That in turn means my brother is 18 years old.

mRNA is to transcription and tRNA is to translation.

The tRNA molecules are in charge of pairing amino acids with the proper codons in the mRNA. Each tRNA molecule has two separate ends; one of them attaches to a particular amino acid, while the other one binds to the appropriate mRNA codon. These tRNAs transport amino acids to the ribosome during translation where they combine with their complimentary codons.

The formed amino acids are then linked together as the ribosome advances along the mRNA molecule in a ratchet-like process, assisted by its resident rRNAs. The resultant protein chains can include hundreds of amino acids, and it takes a lot of chemical energy to create these molecules.

The heterotroph is an organism that must obtain organic compounds for its carbon needs (option B)

Heterotrophic organisms are those that are dependent on plants or other organisms for sustenance since they are unable to produce it on their own. Heterotrophs include all mammals, protozoans, fungi, and the majority of bacteria. Every living thing needs a supply of carbon in the form of lipids, carbs, and proteins since they are necessary for energy. Heterotrophs get their carbon from organic substances, typically from plant or animal matter.

Any organism classified as a heterotroph requires organic substances as a carbon source for the synthesis of its own cellular constituents.
