What is the result when a single cell reproduces by mitosis?
two cells with genetic material identical to the parent cell
two cells with half the genetic material of the parent cell
four cells with half the genetic material of the parent cell
four cells with genetic material identical to the parent cell
Answer: The answer is two cells with genetic material identical to the parent cell.
Explanation: I am also studying this in class and we went over many instances where this question was brought up and the correct answer is four cells with genetic material identical to the parent cell because besides the fact that when you reproduce one cell you get two cells, (which makes logical sense from both a science and a math standpoint) you always have identical DNA to the parent cell and you never get half of it or else it would mess up the whole reproductive process.
The result when a single cell reproduces by mitosis is TWO cells with genetic material IDENTICAL to the parent cell.
Mitosis is a type of cell division by which a parent cell divides to produce two genetically identical daughter cells.
Conversely, meiosis is a type of reductional cell division that produces four daughter cells (gametes) from one parent cell. These cells have half of the genetic material as the original parent cell.
Mitosis divides into four stages: prophase, metaphase, anaphase and telophase.
In conclusion, the result when a single cell reproduces by mitosis is TWO cells with genetic material IDENTICAL to the parent cell.

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

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?
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)

Answer:
A centriole
Explanation:
is a small set of microtubules arranged in a specific way. There are nine groups of microtubules. When two centrioles are found next to each other, they are usually at right angles. The centrioles are found in pairs and move towards the poles (opposite ends) of the nucleus when it is time for cell division.

How do the Earth, the Sun, and the moon interact to influence the time patters of tides?
Answer:
Explanation:
When the sun, moon, and Earth are in alignment (at the time of the new or full moon), the solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very low, low tides, both commonly called spring tides. A similar situation occurs between the Earth and the sun.
