Answer:
The presence of extra centrosomes leads to the formation of a multipolar mitotic spindle, which, if not corrected prior to anaphase, results in the segregation of chromosomes into more than two daughter cells.

How does one distinguish
between the left & right
sides of a heart?
Answer:
See explanation section for answer:
Explanation:
The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.
Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.

What is the % of water inside the cell
Will osmosis occur
If so , which will water move (into or out of the cell )?
Will the cell swell or shrink ?
The cell is In what type of solution ? (Hypertonic , hypotonic ,isotonic ) help pls
The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.
What is osmosis?
Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.
A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.
Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

The eyes of some birds contain cells that detect ultraviolet (UV) light.
UV light is reflected by some fruits and the urine of small mammals.
Explain how birds that detect UV light have evolved from birds that could not detect
UV light
[6 marks
Birds that detect UV light have favorable characteristics that enable them to survive and reproduce. These characteristics are passed on to their offspring.
According to Darwin's theory of evolution, organisms that are better adapted to their environment live long enough to survive and reproduce and pass on these favorable traits to their offspring.
Since birds depend on these fruits for food and these fruits reflect UV light. A bird that can not detect UV light will find it difficult to obtain food. Hence, birds that have developed the ability to detect UV light will live long enough and reproduce, passing on these favorable characteristics to their offspring. Hence, birds that can detect UV light appears from birds who do not originally detect UV light.

which is colder 0 C or 32 F
Answer: we know that the same temperature was named 0°C and 32°F. We write it 0°C = 32°F, and read it: "A temperature of zero degrees Celsius is the same as a temperature of 32 degrees Fahrenheit." Similarly, 0°F = 160/9°C. ... 23°C is 23°C above 0°C. But 23°C = 23*1.8°F and 0°C = 32°F.
Explanation: Mark me brainly please
Answer:
They are the same
Explanation:
(0°C × 9/5) + 32 = 32°F
To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.

why do biomes differ
Answer:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
Explanation:
Biomes differ in the amount of precipitation they receive, their temperatures, and the life that inhabits each biome.
For example, the types of organisms found in the subtropical desert differ drastically from the organisms found in a tropical rainforest. Each organism is well-adapted to its environment, and a subtropical desert and tropical rainforest are two very different biomes.
If you look at the graph below, you can see that the tropical rainforest has high average temperatures and high precipitation, whereas subtropical deserts have much lower precipitation and great variation in average temperature.

How do protons (hydrogen ions) move through
ATP synthase?
Answer:
Protons flow down their concentration gradient into the matrix
Explanation:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
