Carbon dioxide is what humans exhale, giving trees carbon dioxide will produce oxygen
Answer:Wildebeest are considered keystone species because their presence has myriad effects on the ecosystem, unlike those of any other species. Wildebeest are the "lawnmowers" of the Serengeti grassland. They keep grass short which in turn reduces the frequency of fires.
Answer:
B.) Diffusion
Explanation:
Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.
The process of translation
involves each codon calls for a specific nucleotide. The answer is letter A.
during translation, an mRNA sequence is read using the genetic code to be
translated into the 20-letter code of amino acids.
Answer: Option A) This is an anabolic process.
Explanation:
An anabolic process is simply a constructive process in which complex molecules are synthesized from simpler ones.
Thus just as photosynthesis or glycogen synthesis that yields complex molecules, since DNA replication leads to the synthesis of long double-stranded polynucleotides wounded together from a single strand (as in semi-conservative replication); we can therefore conclude that it is a anabolic process.
