Correct Answer: Chromosome
Correct Answer: Etiology
Correct Answer: Rough and sticky
Correct Answer: whittaker
Correct Answer: Fungi
Correct Answer: Water
Explanation:
Electrons are stripped from water in the light reactions of photosynthesis. Light provides the energy to excite electrons.
ATP and NADPH are both products of the light reactions and are used to power the Calvin cycle.
Correct Answer: 3
Explanation:
3 Nucleotides make up a Codon.
The nucleotide triplet that encodes an amino acid is called a codon.
Each group of three nucleotides encodes one amino acid.
Correct Answer: 20 to 45 degrees Celsius
Explanation:
The Bacteria that causes Food Borne illness are called Food Borne Pathogens. Most of the pathogens are mesophilic in nature, optimum temperature may be around 20-45 degree celsius. This range of temperatures is often called the "Danger Zone." Dry foods do not support the growth of bacteria.
In order to kill pathogenic bacteria you need temperatures above 74ºC. Temperature is the easiest factor to control in order to prevent bacterial growth.
Correct Answer: Nucleotides are the building blocks of the DNA and RNA used as genetic material Nucleotides also are used for cell signaling and to transport energy throughout cells Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts:: 1 Nitrogenous Base 2 Pentose Sugar 3 Phosphate Group
Correct Answer: interphase
Explanation:
Nucleoli are present during Interphase.
Chromosomes become visible during Prophase.
Centromeres divide and sister chromatids become full-fledged chromosomes during Anaphase.
Spindle fibers attach to kinetochores during Prometaphase.
