If a person could not digest food anymore, what would probably happen to that person? ... The person would gain weight because the undigested food would sit in the person's body. The person would not lose or gain weight, but it would take longer for the body to use the food that was eaten.

During an action potential, the rapid decrease in sodium ion permeability and the simultaneous and rapid increase in potassium i

I am Lyosha [343]

The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.

In many states, the legal limit for all bacteria present in pasteurized milk is not to exceed 20,000 CFU/mL. You have been away

zaharov [31]

Answer:

a. The formula for finding the number of colonies in a given volume is,

CFU/ml, here CFU is the colony forming units or the number of colonies formed in a volume plated in ml × dilution

The dilution factor given in the question is 1 × 10⁻⁴ and the number of colonies given is 186. Therefore, the number of bacteria present in the given 1 ml of the milk is,

CFU/ ml = 186 / 1 × 10⁻⁴ = 186 × 10⁴.

Hence, the concentration of bacteria in the milk is 186 × 10⁴ CFU/ml.

b) The limit of the bacterial concentration in the pasteurized milk is 20000 CFU/ml, however, it can be seen that the sample of the milk possess more concentration of bacteria than the desired value. Therefore, the milk is not safe to drink by Public Health Standards.

Dentify the relationships between the zooxanthellae and the hard coral, the remora and the manta ray, the tiger shark and the gr

sergeinik [125]

Answer:

1. Mutualism

2. Mutualism (it was previously thought to be a case of commensalism)

3. Predation

4. Competition

Explanation:

1. Zooxanthellae and hard coral - Mutualism

These two organisms live in symbiosis. This means that both benefit each other. Zooxanthellae allow corals to gain energy through photosynthesis and, in turn, they receive important nutrients that are produced during the metabolism of the hard coral.

2. Remora and manta ray - Mutualism

Remoras and manta rays benefit each other. Remoras attach to manta rays mainly for transportation and feeding, but they also do it for protection. In turn, they make sure manta rays are clear from harmful bacteria and parasites. Several years ago, it was thought that manta rays didn't gain any benefit from remoras, so this was thought to be a case of commensalism. However, research has shown that they both benefit from each other. Therefore, this is also a case of mutualism.

3. Tiger shark and green sea turtle - Predation

In some areas (not everywhere) tiger sharks feed upon green sea turtles. For example, in Hawaii, have been observed to attack green sea turtles and feed on them. Researchers have spotted numerous sea turtles with characteristic tiger shark bites.

4. Dolphins and school of trevallies - Competition

Trevallies are large species of fish that feed on small schools of fish like dolphins. They both have their own predatory strategies that involve planning and gathering to catch large amounts of fish. Therefore, trevallies and dolphins compete for small schools of fish.
