Answer:

The correct option is 'c'

The archaea and bacteria diverge from early eukarya.

Explanation:

The cell wall material is different from archaea with bacteria as the cell wall of archaea lack peptidoglycan and contain lipid and hydrocarbons rather than fatty acid but the cell wall of bacteria contain peptidoglycans.

Archaea and bacteria both derived from eukarya as they both have similarities with eukarya.

The similarity between archaea and bacteria is that they both share lateral gene transfer.

There are similar features that are seen between archaea and bacteria like protein secretion,ATP production,protein modification etc.

Both bacteria and eukarya belongs to prokaryotes and the membrane of both eukarya and bacteria contain unbranched fatty acid chain that are attached to glycerol with ester bond.

guajiro [1.7K]

Answer:

99 to 138.6 bpm

Explanation:

The heart rate of an individual is a measure of how many times the heart beats in a given time, usually measured in beats per minute (bpm).

Resting heart rate is the number of beats per minute when an individual at rest. Generally, it can be understood that the lower the resting heart rate, the more physically fit an individual is.

The maximum heart rate for an individual is 220 minus their age. The target heart rate for moderate physical activity is 50-70% of the maximum heart rate and for vigorous physical activity it is 70-85% of the maximum heart rate.

Based on Holly's age, her maximum heart rate is 220 - 22 = 198 bpm

Her heart rate zone for moderate physical activity is 50-70% of 198 bpm: 99 to 138.6 bpm

Her heart rate zone for vigorous physical activity is 70-85% of 198 bpm: 138.6 to 168.3 bpm

The concentration of a biomolecule inside a rod-shaped prokaryotic cell is 0.0037 m. calculate the number of molecules inside th
Talja [164]

First, let calculate the volume of the rod shaped-bacteria:

S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3

Now, let's convert the moles into molecules (with Avogadro's law):

0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L

Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)

1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3

so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3

The answer is  2.22 10^ 12 molecules / µm3
