<span>This is true. Alcohol interacts with more neurotransmitters and genes than pot and cocaine. This is because not only does it stimulate the neurotransmitters to produce a chemically altered state, but people can have genetic predispositions to alcohol addiction.</span>
Answer:
Most living tissue contains catalase. We can use potatoes to help see catalase work because bubbles of oxygen form when we put potatoes into hydrogen peroxide.
Explanation:
As catalase decomposes hydrogen peroxide into water and oxygen gas, bubbles of oxygen collect on the disk. When the density of the combined paper/enzyme/O2 is less than the solution the disc will rise to the surface.
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).
Answer:
The genotypic ratio and phenotypic ratio are different when a monohybrid cross is done because multiple genotypes often result in the same phenotype.
