Based on your experimental results, categorize each microbe as preferring isotonic environments, being halotolerant, or as a hal

ophile.

NISA [10]2 years ago

The microbes present in the experiment were:

S. cerevisiae

S. epidermis

A way of categorizing microbes is according to the environment that they need to live in. In other words, we can classify them as isotonic, halotolerant and halophile.

If we put these two microbes in solutions of increasing concentrations, 1%, 7% and 15%, we will see that:

  • S. cerevisiae only grows when it is in a 1% solution.
  • S. epidermis only grows when it is in a 1% and 7% solution.

In conclusion, S.cerevisiae prefers an isotonic environment. S. epidermis is halotolerant since it can grow in a more hypertonic environment. As none of them grows in a highly hypertonic solution, neither of them are halophile.

The nucleotide variation is obtained by comparing nucleotide sequence between individuals between individuals of a particular population. If genetic variability is 0 % then the number of alleles would be 1.

<h3>What is genetic variability?</h3>

Genetic variability is the evolutionary process and development of new species. Genetic variability describes the dissimilarities such as brown eyes, blue eyes that happen naturally when DNA is altered.

Genetic variability varies in population. Genetic variability describes the tendency at which traits in a population may vary.

Gene variation refers to a differences in the genetic makeup of the individual. Genetic variation is a important process of natural selection and biological evolution.

Therefore, The nucleotide variation is obtained by comparing nucleotide sequence between individuals between individuals of a particular population. If genetic variability is 0 % then the number of alleles would be 1.

After the depletion of hepatic glycogen in newborns, which compounds can be used as precursors to sustain the blood glucose leve
VashaNatasha [74]

Answer:

Nutrients from breast milk.

Explanation:

Healthy newborns make blood glucose from sugar and several nutrients from the colostrum, a type of liquid that mother’s breasts produce before breast milk itself. Later, the babies make glucose from mature breast milk.

Most healthy babies, born after 37 weeks of gestation do not risk hepatic glycogen drops. They can easily compensate for normal drops in blood sugar, in other words, whenever the baby is breastfed when needed, he/she will be able to keep  his/her glucose levels stable.
