Answer:
Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal's genes are expressed, which ultimately affects the animal's phenotype.
Explanation:
Answer:
This statement is true
Explanation:
The genetic code is required for the production of proteins with exception of some few mitochondrial proteins. The transfer RNA (tRNA) acts as an adaptor that enables to associate a messenger RNA trinucleotide sequence (known as anticodon) with its corresponding amino acid in the polypeptididic chain. The genetic code is considered to be a biochemical system capable of revealing the information contained in the DNA in order to synthetize a protein, which has been encrypted in the form of three nucleotides (i.e., codons).
Answer:
d
Explanation:
Your heart is an organ that’s largely made up of muscle. It has the vital function of working to pump blood to the organs and tissues of your body.
Tobacco mosaic virus (TMV) is a simple rod-shaped helical virus that contains single stranded RNA situated at its middle and is surrounded by a protein coat called capsid. After tobacco mosaic virus enters its infected host cells through mechanical inoculation, it removes its capsid to release its single stranded viral nucleic acid which is then transported into the nucleolus. The single stranded viral RNA actuates the production of specific enzymes (RNA polymerases) and it also produces another RNA strand (replicative RNA). The new viral-RNAs are transported from the nucleus into the cytoplasm and functions as messenger-RNAs (mRNAs). Each mRNA, ribosomes, and t-RNA, of the infected host cell all controls the production of protein subunits (capsomeres). After the production of the preferred capsomeres, the new viral-RNAs arrange the capsomeres around it which lead to the production of a complete virus particle (virion). The viruses then migrate from one cell to another. Hence, creating organized infection.
The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .
