The best answer is D.
Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.
In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached mRNA is decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.
The correct answer is: A) GABA
GABA or γ-aminobutyric acid is a type of amino acid that's found in proteins. It is the main inhibitory neurotransmitter in the brain which means that GABA reduces neuronal excitability throughout the nervous system. GABA binds to its receptors that are located on the neuron’s plasma membrane. This binding causes the opening of ion channels that transport chloride ions into the cell or potassium ions out of the cell.
No, Humans take evolution through selective breeding and genetically modified organisms.
The answer would be C. Energy is used through the food chain so energy always decreases. Population size would commonly decrease according to the pyramid of food chain but since there's no answer for that, C would be the most suitable
I think it’s money sorry if I’m wrong
