Bioticas
Bioticas son seres vivientes que necesitan oxygeno o dioxido de carbono por whemplos seres humanos, plantas o bacterias.
Abioticas son seres que no son viviento que no necesita oxigeno como agua, el viento y precipitación
Answer:
False
Explanation: Heterotrophs benefit from photosynthesis in a variety of ways. They depend on the process for oxygen, which is produced as a byproduct during photosynthesis. Moreover, photosynthesis sustains the autotrophs that heterotrophs depend on to survive
Answer:
People, not machines, perform fingerprinting. They do search for a particular amount of matches before taking into account a whole match.
Explanation:
Answer: carbohydrates is composed of amino acids
Explanation: carbohydrate functions as an energy giving food in the body. Examples are rice, casssava and maize. The molecular structure of carbohydrate is (CH20)n. Carbohydrate has three subtypes:
(1) Monosaccharides: They are simple sugar and consists of a number of carbons(C) which ranges from 3 to 7.
(2) Disaccharides: They are formed when two Monosaccharides undergo a dehydration reaction which is also known as condensation reaction. thanks
(3) Polysaccharides: They consist of a long chain of branched or unbranched
Monosaccharides Monosaccharides linked by covalent bonds.
Carbohydrates is not composed of amino acids but rather protein is composed of amino acids.
Answer:
An amino acid activates the repressor so that the repressor binds to the operator and prevents transcription.
Explanation:
In an operon, promoter is followed by operator which is finally followed by the structural genes to be transcribed. RNA Polymerase binds to the promoter and initiates transcription. A repressor can negatively control the transcription process by binding to the operator so that the RNA Polymerase is not able to move forward and transcription is halted.
For example: in trp operon, tryptophan amino acid binds to the repressor molecule which leads to change in repressor's shape. The repressor is now able to bind to the operator and prevent transcription.
