Answer:
For example, delays in mitosis are often ascribed to 'activation' of the mitotic checkpoint, a descriptor that fails to recognize that the checkpoint by definition is active as the cell starts mitosis. Conversely, the completion of mitosis in the presence of misaligned chromosomes is often automatically interpreted to indicate a defective checkpoint, even though in the absence of critical testing alternative interpretations are equally likely. In this article, we define the critical characteristics of checkpoints and illustrate how confusion generated by the inconsistent use of terminology may impede progress by fostering claims that mean very different things to different researchers. We will illustrate our points with examples from the checkpoint that controls progression through mitosis

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults
Would extraterrestrial life on other Earth-like planets look similar to organisms found here on Earth?
Answer: I don't think they would since all the planets we know have completely different conditions than ours.
Explanation:
Depends on the biosphere of the other planet, any living thing on another planet would adapt to that planets resources, atmosphere, and climate. SO if that planet was almost identical to ours then maybe? We still have to factor in speed of evolution and whether or not they are put through the same events or big changes that earth life has been put through. I hope this helps!

Is baking soda organic or inorganic explain why?
Answer:
Inorganic
Explanation:
Baking soda can be found as a naturally occurring compound, but is more frequently manufactured from other naturally derived materials, like trona ore. Baking soda can be produced by the reaction of carbon dioxide and soda ash, a naturally occurring mineral. To my knowledge there is not an “organic” baking soda.

what is the benefit of the pigments in photosynthesis
Answer:
Because they interact with light to absorb only certain wavelengths, pigments are useful to plants and other autotrophs --organisms which make their own food using photosynthesis. In plants, algae, and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis.

How the nervous and endocrine systems maintain homeostasis?
Answer:
Hope this helps :D
Explanation:
Homeostasis is the process of how you have a controlled body temperature.
The nervous system detects that your body temperature is falling (or rising) so the endocrine system send the chemical messengers (hormones) to bring the body temperature back to normal.
Cells reproduce by splitting in half a process called cell division what do you cells need between divisions to make sure that they don’t get smaller and smaller

Explanation:
A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.
Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.
What are balanced forces?Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.
Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.
An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.
While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.
Therefore the correct option is D.

How do the chromosomes in most cells of an organism, such as the leaf cells of a plant, compare to the chromosomes in its reproductive cells, which are sperm and egg cells
Chromosomes in "most cells of the organism"(somatic cells) are diploid and the chromosomes are grouped in pairs while the chromosomes in reproductive cells are not paired so there are half the number that would be found in somatic cells so the sex cells are haploid.
