A Eukaryote has a nucleus.
Answer:
Explanation:
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
DNA is a negatively charged component so the amino acids most probably to combine with the DNA are going to exhibit a positive charge at pH 7. Thus, the likely amino acids would be Arginine, Histidine, and Lysine.
There are three amino acids, which possess basic side chains at neutral pH. These are lysine, arginine, and histidine. Their side chains comprise nitrogen and bear a resemblance to ammonia that is a base. Their pKa values are high enough that they seem to combine with protons, thus, attaining a positive charge in the process.
Answer:
long term development or proper utilization of plants
Answer: b. It only arrest growth of vegetative cells
Explanation: An antimicrobial agent is a substance that kills o control the growth of microorganisms, for humans this is very important in medicine or agriculture among others.
This agent should act quickly and being stable that help it to make it cheaper, also should not harm humans or other host of the microbial organisms.
The agent is not useful if only kills vegetative cells because it is not preventing the reproduction of the organism specially in fungi which use sexual reproduction as a backup for asexual cell division, so they will keep spreading across the host.
