Answer Options:
a. Cells are the basic units of structure and function in living things.
b. New cells are produced from existing cells.
c. All cells enclose their DNA within a nucleus.
d. All living things are made up of cells.
Answer:
a. Cells are the basic units of structure and function in living things.
b. New cells are produced from existing cells.
d. All living things are made up of cells.
Explanation:
Cell theory states that cell living organisms are composed of at least one cell, which are the basic unit of life.
Cells are always produced from other living cells, and cannot spontaneously generate.
However, not all cells enclose their DNA within a nucleus, prokaryotic organisms (bacteria) do not possess a nucleus but still have DNA
3 nucleotides code for a single amino acid. This group of 3 is known as a codon. If you are coding for two amino acids, you would need two codons, 3 nucleotides each, for a total of 6 nucleotides.
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -liquid.
Answer:
Innate or natural immunity
Explanation:
Innate immunity is a defense system that we are born with and that protects us against antigens. It is the sum of all defense mechanisms that occur naturally to protect an individual from infectious diseases. They are physiological mechanisms that are present throughout the entire animal kingdom and it is an inherent quality of each species.
They are not specific to a given pathogen, nor do they generate memory
