All of the following refer to mitosis, except repair of damaged cells. production of genetically identical daughter cells. formation of gametes. growth of an organism. asexual reproduction.
Answer:
formation of gametes.
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
Differentiation can be defined as the process in which a cell changes from a generalized cell type into a specialized cell type for performing specific functions in the body.
Mitosis can be defined as a type of cell division that occurs in all body cells found in living organisms.
Hence, all of the aforementioned statements refer to mitosis, except formation of gametes.
In living organisms, the formation of gametes is linked or has to do with meiosis.

What process in biology requires energy from a cell?
Answer:
I would assume you are talking about just basic general biology, in which case it's probably just looking for cellular respiration.
Explanation:
Besides oxygen exchange, the respiratory system also functions to eliminate (Click to select) . Too much of this gas can cause a(n) (Click to select) in blood pH, compromising homeostasis.
Answer: Carbon dioxide, decrease
Explanation:
Cellular respiration is a set of reactions by which organic compounds (sugars) are degraded by oxidation to inorganic substances. This process provides energy in the form of ATP and to achieve this, many reactions occur in which electrons are passed from one molecule to another, called redox reactions. In the case of aerobic respiration, the final electron acceptor is molecular oxygen, which is reduced to water. Oxygen, like any gas, crosses the plasma membrane and then the mitochondrial membrane, and in the mitochondrial matrix it binds electrons and protons, forming water. It is in this final oxidation and in previous processes that energy is obtained. The reactions that extract energy from sugars such as glucose are catabolic reactions since a large molecule is broken into smaller molecules. For example, when glucose is broken down in the presence of oxygen, six molecules of carbon dioxide (CO2) and six molecules of water are obtained. Both CO2 and water are eliminated by lung exhalation.
In the event that this carbon dioxide is not completely eliminated, something called respiratory acidosis occurs, which is one of the disorders of the acid-base balance due to a decrease in the frequency of respirations or hypoventilation. The increase in the concentration of carbon dioxide in the blood causes the pH value to decrease. This scale is a measure of the degree of acidity or alkalinity of a substance or solution. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more alkaline. Carbon dioxide is constantly produced as the body metabolizes energy, which will accumulate in the circulation rapidly if the lungs do not remove it properly. Alveolar hypoventilation thus leads to an increase in arterial CO2 partial pressure. The increase in pressure in turn decreases the ratio of bicarbonate (HCO3) to bicarbonate pressure with a consequent increase in acidity or decrease in blood pH. The body's metabolism rapidly generates a large amount of carbonic acid (H2CO3) and non-volatile acid. The lungs normally excrete the volatile fraction through ventilation without accumulation of acid in the blood but in this case this is not possible and this accumulation of carbonic acid causes the pH to rise. This disrupts homeostasis, a form of equilibrium that is achieved through a network of feedback control systems that constitute the self-regulatory mechanisms.

a. significantly lesser
b. lesser
c. about the same
d. greater
e. significantly greater
Answer:
a. significantly lesser
Explanation:
The density of protists living in the hay infusion is significantly lesser than the regular pond water because protists likes to live in aquatic or any water bodies. Some protists float on the surface of the water making their own food like plants by using the process of photosynthesis. Aquatic environments are ideal environment for protists, which have cilia and flagella that allows them to move in the water in search of food..
When the belt is moving at a high speed, 350 pills can be coated per hour. How many minutes would it take to coat all the pills in this batch at a high speed?
Answer:
6 pills are coated in one minute time.
Explanation:
There are 350 pills can be coated in 60 minutes due to high speed of belt movement which means that 6 pills are coated in one minute time period so if there are 60 pills so the belt takes 10 minutes to complete the coating of the pills. If there are 200 pills to be coated then we used the equation i.e.
6 pills -------- 1 minute
200 -------- x
By cross multiplication we get,
6x = 200 x 1
x = 200 / 6
x = 33.3 minutes
This means that in 33 minutes the belt can coated 200 pills.
