I need help with the image (phenotypes and genotypes).
Flauer [41]

Answer:

See the answer below

Explanation:

1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.

2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.

3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:

     AA   x   aa

  Aa   Aa   Aa   Aa

All the F1 offspring will appear tall and their genotypes would be heterozygous.

4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>

5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>

Anna11 [10]

The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.

The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

Grace [21]

Answer:

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

Explanation:

You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),

which is used frequently in biological experiments.

Based on your answer above, what is the value of x?

Solution:

A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.

250 ml = 0.250 liter

Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose

Recall:

Mass = number of moles * mass of 1 mole

mass of 1 mole of C12H22O11

= 12(12) + 1(22) + 16(11)

= 144 + 22 + 176

= 342 grams

Mass = 0.1375 * 342 = 47.025 grams of sucrose.

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

expeople1 [14]

Answer:

Legionella tends to form biofilms and infect other microbial cells as intracellular pathogens.

Explanation:

The Legionella genus of the bacteria is a group of gram-negative bacteria that can cause legionnaires disease.

The<em> Legionella pneumophila</em> is a species of this genus which can cause legion pneumonia. The bacteria lives in the freshwater and is resistant to chemical treatment like chlorine and the biocide treatment.

The reason for this resistance is since this species form a polysaccharide layer around the colony of the bacteria which is resistant to these treatments and also the bacteria prove parasitic to the protozoans which feed on these bacteria.

Thus, the selected option is the correct answer.
