01. Bacteria are microscopic organisms present everywhere in our environment. They multiply by binary fission. In order to grow
Marina CMI [18]

Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors influencing microbial growth. In most buildings, warmth and moisture are the most significant overall issues current

<h3>How the bacterial growth curve relates to what happens to the bacterial population?</h3>

The bacterial growth curve symbolizes the number of live cells in a bacterial population over a period of time. There are four different phases of the growth curve: lag, exponential (log), stationary, and death. The initial phase is the lag phase where bacteria are metabolically functional but not dividing.

<h3>What are 4 states of bacterial growth?</h3>

Bacteria can live in more burning and colder temperatures than humans, but they do best in a warm, moist, protein-rich atmosphere that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria flourish in extreme heat or cold, while others can stay under highly acidic or extremely salty conditions.

Answer:

Pleiotropy

Explanation:

Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism

  • <em>gene pleiotropy</em>
  • <em>developmental pleiotropy</em>
  • <em>selectional pleiotropy</em>
  • <em>antagonistic pleiotropy </em>

<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>

Think about the dna coding sequence of a gene. if an a were swapped for a t, what kind of mutation could it cause and why?
sukhopar [10]
If an A (Adenine) were swapped for a T (Thymine) it will lead to A TRANSVERSION TYPE OF POINT MUTATION.

Replacement of an A with a T is a transversion type of point mutation because in transversion the purine is replaced with a pyrimidine. Since in this case only one nucleotide is replaced, it is a point mutation.
