Answer:

B. rr

Explanation:

Genotype- Is the genetic makeup of an organism.

An homozygous individual is one who has similar allele e.g AA

It could either be in dominant form(AA) or recessive form(aa)

An heterozygote individual has two different allele in its genotype e.g Aa

A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.

The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.

The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.

What best explains why different cells within and individual organism function differently
Alexus [3.1K]

Answer:

The majority of living things are made up of various types of cells that are each specialized to execute a specific purpose. Because certain enzymes, also known as proteins, play a big role in biochemical function, distinct sets of genes must be turned on and off in different cell types. This is how cells differ from one another.

Escherichia coli has a doubling time of 30 minutes. If a culture has 10 E. coli cells at the beginning of log phase, how many E.
Nat2105 [25]

80 E. coli cells will be in the culture after two hours.

<h3>What is culture?</h3>

The development of the human, plant, or animal cells in a lab, as well as microorganisms like bacteria and yeast. Cell cultures can be used for research, medication testing, and infection diagnosis.

Primary (mortal) cultures and cultures of established (immortal) cell lines are the two main categories of cultures.

One of the most crucial methods in cellular and molecular biology is cell culture because it offers a platform for studying the biology, biochemistry, physiology, metabolism, and other aspects of both healthy and diseased cells.

A culture of 10 E. coli cells.

Incubation time = 2 hours = 120min

Doubling time = 30min (120/30 = 4)

So, 1 cell - 30min = 2 cells - 30min = 4 cells - 30min = 8 cells - 30min

Therefore, 8 ₓ 10  = 80cells of E. coli at the end of 2 hours of incubation time.
