Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
Answer:
Recently work in evolution theory has proposed that by relaxing selection pressure, which typically acts to streamline genomes, the complexity of an organism increases by a process called constructive neutral evolution.
Explanation:
Answer:
An estuary can be described as an area of brackish water where different rivers or streams meet the open sea. Hence, an estuary forms a transition zone between an river environment and a marine environment.
Estuaries hold a lot of importance and are referred to as the nurseries of the sea. The estuary are home to many unique kinds of organisms. Certain kinds of fishes and shellfishes which humans consume cone from this area of the sea. There are high levels of nutrients moving in the estuary zone of the sea. Due to its shallow water, Pamlico estuary provides opportunities for fishing, crabbing and water- sports activities.
Answer:A
Explanation: of course 30% fewer calories than that which they will normally eat because of their body size.
Answer:
Structurally, the ribosome comprises of two major parts: The small ribosomal units and the large ribosomal units. Each unit contains ribosomal Ribonucleic acid molecules, which is usually one or more than one called rRNA. Each unit also contain ribosomal protein, rproteins. Each of these components are very important for the translation of messenger RNA into proteins encoded by the RNA.
Explanation:
The ribosome and its components are generally referred to as translational apparatus. The small subunit of the ribosome is effective in reading the codes encoded on the mRNA, which . The large subunit is needed to actually join the amino acids needed to form the right protein (or polypeptides). The proteins within the ribosome is used to act as a scaffold that only aid the ribosome ability to form polypeptides.
Since both prokaryotes and eukaryotes are constantly forming proteins using the amino acids they accumulated through nutrition, therefore, both groups possess ribosome. However, the percentage of rRNA and protein in each group differs. For prokaryotes, the rRNA to protein ratio is close to 2, while in eukaryotes like human is close to one.
