This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Methionine-methionine leucinelysine that a mutation in the DNA occurs so that the fourth base (counting from the 5' end) of the messenger RNA.
mRNA codons are read from 5' to 3' , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. The mRNA sequence is: 5'-AUGAUCUCGUAA-5'
Ciodons which is broke the sequence into a series of three-nucleotide units. There are three-letter nature of codons that the four nucleotide found in mRNA such as A, U, G, and C all these can produce a total of 64 different combinations. The sequence of the tRNA anti-codon is 3'-UGC-5' and the tRNA will carry the amino acid which is the encoded by the codon.

Answer:
The large central vacuole is surrounded by its own membrane and contains water and dissolved substances. Its primary role is to maintain pressure against the inside of the cell wall, giving the cell shape and helping to support the plant. ... The cell wall shapes, supports, and protects the cell.
Explanation:
The rocks which are porous depending on the degree of cementation
include the following:
<h3>What is Porosity?</h3>
Porosity is the measure of empty spaces in a particle which permits the
passage of compounds such as water etc.
The rocks mentioned above have a lot of empty spaces which permits
other substances to pass through them. The remaining rocks are
composed of tightly held grains which reduces their porosity.
