The formula for bacteria growth rate is N(t) = N(0) * (1 + r)^t, where N(0) denotes the initial bacteria count. Substituting the appropriate values gives us 220 = 20*(1+r)^(24 hours). Solving for r results in approximately 0.105074. A week comprises 168 hours (7 days). Therefore, N(168 hours) can be calculated as 20*(1+0.105074)^168, resulting in an approximate count of 390 million bacteria after one week.

How many kinds of gametes will be expected from an individual with the genotype ppccttrr?
garik1379 [2080]

Answer:

From the genotype ppccttrr, we can anticipate 16 types of gametes.

Explanation:

Gametes are haploid germ cells which can be male or female. They can fuse with opposite sex gametes during reproduction to create a zygote.

One example of a gamete is the sperm, which fertilizes the egg in reproduction. Therefore, there will be 16 distinct reproductive cells, each with a single set of unpaired chromosomes that follow the genotype ppccttrr.
