Which organelle plays an important role during mitosis, helping to move chromosomes around the cell
a
Oь
Ос
Od
vacuoles
Golgi bodies
chloroplasts
centrioles
Answer:
Explanation:
Duplicated centrioles are responsible for moving chromosomes during mitosis.
They are involved in the formation and organization of spindle during cell division (mitotic phase) and also in the process of cytokinesis.
It is composed of nine triplets of microtubules that are the proteins of cytoskeleton.
Spindle fibres contain multiple proteins that help in the binding with centromere during cell cycle.
They originate from the poles of the cell by the organelle called centriole, and attached to the kinetochore of the chromatid.
Many spindle fibres are just connected between two poles, as they are not attached to the chromatids.
These fibres orient the chromosomes into pairs, to the metaphase plate into a line during metaphase.
During anaphase they are shortened, which pulls the chromosomes to the opposite poles separated from the pairs.
At the end in telophase, where nuclear membrane becomes visible it disappears.
In this way the spindle fibers help in the separation of chromosomes into two new daughter cells. This process is also known as the distribution of heredity or genetic information between new cells.
when is cystic fibrosis exhibited?
Answer:
Diagnosing cystic fibrosis is a multistep process, and should include a newborn screening, a sweat test, a genetic or carrier test, and a clinical evaluation at a CF Foundation-accredited care center. Although most people are diagnosed with CF by the age of 2, some are diagnosed as adults.

Answer: Diagnosing cystic fibrosis is a multistep process, and should include a newborn screening, a sweat test, a genetic or carrier test, and a clinical evaluation at a CF Foundation-accredited care center. Although most people are diagnosed with CF by the age of 2, some are diagnosed as adults. Also cystic fibrosis carriers do not have CF and are generally asymptomatic, there is emerging research which is finding that some carriers may have very mild symptoms associated with the genetic mutation. These symptoms may be a very pale shadow of the more severe symptoms someone with CF has.

Chromatids are distributed to the 2 daughter nuclei Group of answer choices
M
G2
S
G1
Answer:
M
Explanation:
Mitosis is a type of cell division that involves the production of two daughter cells that are genetically identical to one another. Mitosis encompasses two stages namely: Interphase and Mitotic phase. The interphase which further consists of G1, S, and G2 phases, is a preparatory phase for the cell to grow and replicate its DNA.
However, the separation of the sister chromatids (replicated chromosomes) into two daughter nuclei occurs in the Mitotic or M phase. Note that the M phase comprises of stages that includes: prophase, metaphase, anaphase and telophase.
Answer:
M phase

The ocean has a large impact on the climate of locations around the world. In particular,(Blank) than
have a milder climate than (blank)
answer choices for both - inland locations, locations near the coast
Answer:
First box is inland locations and the other box is locations near the coast.
Explanation:
When your inland the climate is a lot warmer than if your on the coast. If your on the coast during the day cold air from the ocean gets pushed inland near the coast then pushed back out to sea.That's why when your on the beach it's colder and windy.
Answer: The answer is The ocean has a large impact on the climate of locations around the world. In particular, inland locations have a milder climate than locations near the coast .

PLEASE HELP!!!!!!
Red blood cells transport oxygen to every cell in the body. This oxygen is needed to release energy stored in glucose molecules. Red blood cells also transport carbon dioxide, a waste product produced by cells, back to the lungs where it is exhaled. When a person exercises, his or her muscle cells consume more oxygen and produce more carbon dioxide. The body responds by increasing its breathing rate and heart rate to supply more oxygen-rich blood to the muscles and carry away more wastes. Explain how this is an example of maintaining homeostasis.

Explanation:
How did the 2014 Colorado case demonstrate just what a versatile zoonotic disease the plague is?
A.) In this case, antibiotics were not effective against the bacteria.
B.) In this case, scientists could not track down a specific host.
C.) In this case, the bacteria infected humans through a dog.
D.) In this case, the bacteria had been dormant for decades before regenerating.
Answer:
C). In this case, the bacteria infected humans through a dog.
Explanation:
The Colorado Department of Public Health and Environment (CDPHE) in July 2014 witnessed the 'Yersinia pestis' bacteria from the blood of a patient with Pneumonia. It was later noticed that the patient got infected through a dog suffering Hemoptysis. This pneumonic plague case even caused the human-to-human transmission of the bacteria along with the animal-to-human. Thus, option C correctly displays how the plague is a versatile zoonotic disease.
Answer: C
In this case, the bacteria infected humans through a dog.

Which population is most likely to be in Hardy-Weinberg equilibrium?
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
a large population of prairie grasses that lives in an ecosystem that is frequently burned by wild fires
a medium-sized population of birds that lives on a chain of islands that have different food sources
a medium-sized population of bacteria that lives on crop plants that are frequently sprayed with pesticides
Answer:
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
Explanation:
This is because the Hardy-Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. So if the large population of ocean fish isn't being disturbed by the pollution (unpolluted) and they have an abundant source of food they should in Hardy-Weinberg equilibrium since no major changes are happening.

Choose 1 answer:
A.) Glycolysis -> Krebs cycle —> oxidative phosphorylation
B.) Glycolysis -> alcohol fermentation
C.) Glycolysis -> Krebs cycle -> fermentation
D.) Glycolysis -> lactic acid
fermentation
Answer:
B.) Glycolysis -> alcohol fermentation
Explanation:
The correct pathway of anaerobic respiration in yeast is Glycolysis -> alcohol fermentation. Thus option B is correct.
what is alcohol fermentation ?Alcohol fermentation is a complex process where sugars like glucose, sucrose, and fructose are converted into ethanol, carbon dioxide, and other metabolic by-products, these products are mainly contribute to the sensorial properties and chemical composition of the fermented food.
It is also called as ethanol fermentation is processed by yeast or some other microorganisms, used to make ATP. Yeast functions in the presence of oxygen called as aerobic fermentation but it can also perform in absence of oxygen or under anaerobic conditions.
This process show has a profound importance for the manufacturing of alcoholic beverages like beer and wine.

Answer:
The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is 3
Explanation:
There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total, there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.
