why the dates on the geologic time scale are often changed and updated.

Answers

Answer:

Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. ... The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

The small intestines of cows are similar in general structure and function to the small intestines of humans. In a cow, damage in the wall of the small intestine reduces the number of villi due to which the cow loses weight and becomes weak. What could be the reason for weight loss and weakness?

Answers

Answer:

Low absorption of nutrients into the bloodstream from digested food.

Explanation:

This question is regarding the small intestine of a cow, which is said to be similar in general structure and function to the small intestines of humans. The small intestine is an organ found in the digestive tract of the cow or human in this case. Its primary function is to absorb the nutrients from the food, that has undergone series of digestion, into the bloodstream.

The small intestine is able to do this with the aid of the finger-looking extensions found on its wall called VILLI. The villi further contains MICROVILLI, which together helps the small intestine absorb nutrients into the blood. Hence, in a case whereby damage in the wall of the small intestine of the cow reduces the number of villi, resulting in weight loss and weakness.

This damage to the intestinal wall will cause a disruption in the absorptive function of the small intestine due to the reduced number of villi. Therefore, THE INABILITY OR LOW ABSORPTION OF NUTRIENTS INTO THE BLOOD THAT THE DAMAGE CAUSES is responsible for the weight loss and weakness in the cow.

The reason for the weight loss and weakness is as a result of decreased

absorption of nutrients from digested food.

The villi is a finger-like structure found in the small intestine which helps in

the absorption of nutrients from digested food into the bloodstream. When

the villi are reduced, the absorption of nutrients are reduced.

This thereby brings about weight loss as a result of nutrient deficiency

caused  by low absorption into the bloodstream of the animal(cow)

How are ammonia, nitrite, and nitrate levels in an aquarium correlated with one another

Answers

Answer:

Ammonia, nitrite and nitrate at higher levels are toxic to fishes in the aquarium.

Explanation:

Ammonia,nitrates and nitrites are all byproducts gotten from organic wastes which is biodegraded in the aquarium. These byproducts are gotten from fish and plant wastes, uneaten algae , bacteria e.t.c. There are bacterias in the aquarium that help to break down nitrogenous wastes in the aquarium.

Therefore, the waste from fish and plants are breakdown by bacteria into ammonia.

Ammonia at high levels are very toxic to fishes. Then the nitrifying bacteria then help to convert ammonia to nitrite.

Nitrite also at high levels is very toxic to fishes in the aquarium.

Nitrite is also converted to nitrate by nitrifying bacteria.

Nitrate is not very toxic and it is use by algae or plants for growth in the aquarium.

5) Anna is correct that all cellular processes that require energy require ATP, but those that do not require energy occur without ATP. However, the process of glycolysis requires the input of ATP energy.

For each cell of the body to perform its normal cell functions, ATP is the primary energy-driving molecule that must be present in the cell. As a result, ATP is referred to as the "energy currency" of the cell.

However, there may be some processes that do not necessitate the use of energy. Diffusion, osmosis, and other processes that occur along a concentration gradient are examples of such processes.

ATP is required for the processes of glycolysis and the Krebs’s Cycle. - ANSWER IS B
