Explanation:
During photosynthesis, molecules in leaves capture sunlight and energize electrons, which are then stored in the covalent bonds of carbohydrate molecules. That energy within those covalent bonds will be released when they are broken during cell respiration. How long lasting and stable are those covalent bonds? The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago.
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis. Because they use light to manufacture their own food, they are called photoautotrophs (“self-feeders using light”). Other organisms, such as animals, fungi, and most other bacteria, are termed heterotrophs (“other feeders”) because they must rely on the sugars produced by photosynthetic organisms for their energy needs. A third very interesting group of bacteria synthesize sugars, not by using sunlight’s energy, but by extracting energy from inorganic chemical compounds; hence, they are referred to as chemoautotrophs.
The ribosomes build proteins.
Answer:
The basic resources a living organism needs to survive are sustinence, shelter, and heat. Sustinence is not an unlimited source and wild animals have to hunt to get their food, and if they hunt too much, the food chain will fall out of balnce to where there is no more of that species.
Shelter or safe homes can also be limited, from animals that find natural spots, or make their own homes out of resources, it can be difficult to not be constantly exposed to the natural environment.
Heat is dependant on climate, and is provided by the sun. Nonetheless, in the winter, it isn't reliable, and in the summer, animals may overheat. In conclusion overall, all of these resources are limited or depending on such circumstances.
Answer:
TRANSCRIPTION
Explanation:
Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.
RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.
In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.
Because l-glucose is toxic in nature.
