Polypeptide:
A chain of amino acids linked together by peptide bonds and having a molecular weight of up to about 10,000.
Dipeptide:
A peptide that yields two amino acids on hydrolysis.
Bacteria need an optimum temperature for their growth, so this is the reason why we might not see as much bacterial colonization of microbes from human saliva on plates cultured at 25 °C versus plates incubated at 37 °C.
Why do bacteria only grow at certain temperatures?
- The main justification for incubating bacterial cultures at various temperatures is that different temperatures favor the growth of particular bacteria.
- Most infections and typical ambient bacteria are classified as mesophiles, which thrive in temperatures between 20 and 40 degrees Celsius.
- An optimum temperature is required for the enzymes to show their activity, and for the division also many enzymes are involved in the process. So, the bacterial culture can be seen at a particular incubation temperature only.

Explanation:
Recessive alleles lack the power to express the phenotypic traits of an organism. In order for the specific trait to be expressed, 2 copies of the recessive allele or homogenous recessive genotype is needed in the organism.

Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks because the extrusive magma cools quickly so the mineral grains do not have time to grow.
When lava comes out of a volcano and solidifies into extrusive igneous rock, the rock cools very quickly. Crystals inside solid volcanic rocks are small because they do not have much time to form until the rock cools all the way, which stops the crystal growth. Magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture.
