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.

(Choice C) X; the activation energy is greater in an uncatalyzed reaction
(Choice D) Y; the activation energy is greater in an uncatalyzed reaction
Report a problem
Answer: Choice C) X; the activation energy is greater in an uncatalyzed reaction
Explanation: I got this question on khan academy.
The option that represents the activation energy of a catalyzed reaction is C. X; the activation energy is greater in an uncatalyzed reaction.
Activation energy simply means the minimum amount of energy that should be provided for compounds that'll result in a chemical reaction.
It should be noted that the activation energy for uncatalyzed conversion to the products will be more than that of the catalyzed reaction. In this case, X; the activation energy is greater in an uncatalyzed reaction.

B. How many offspring can an organism have?
C. Why do different organisms live in different places?
D. Are an offspring's traits similar to those of its parents?
Answer:
The correct answer is C. Why do organisms in different places have different traits?
Explanation:
Charles Darwin was a naturalist, biologist, and geologist from England and known for his theory of evolution. According to the theory, he observed different types of species of organisms such as birds, plants and fossils all over the world and found similarities in the characteristics.
He suggested that there were variations in species on the basis of specific geological locations. On the basis of these observations, he proposed that all species of organisms are come from the same ancestor but shows the differences due to the response to the condition of their habitat or location

Why is some amount of air is left inside in your lungs after inhalation
Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.
So your answer will be Residual volume...
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.
