if the original cell is dead, does it stay their or does it disappear after mitosis?

Answers

Answer:

It disappears. The cell disappears because it can no longer divide if it dies.

if the original cell is dead, the cell is almost dead too. It has no ability to divide itself too.

What are the types of cell division ?

There are two types of division one is mitosis and the other one is meiosis.

Once mitosis completes, the cell has 2 groups of 46 chromosomes, each enclosed by their own nuclear membrane. The cell later splits in 2 by  process called cytokinesis and creates two clones of the original cell each with 46 mono valent chromosomes.

Mitosis is a nuclear division in which duplicated chromosomes segregates and distributed into daughter nuclei. The cell will divide after mitosis in a process called cytokinesis in which the cytoplasm is divided and two daughter cells are formed.

state the consequences of such a situation over the solar system.

thankyou ~​

Answers

Explanation:

Sun plays an important role in our solar system especially planet like earth are dependent on sun for food, water and air. Sun helps to balance the ecosystem on earth.

Here is an assumption what would happen if sun disappear for one day only, it would be more curt if it disappear forever but from POV of one day below are certain consequences of such a situation over solar system,

You might be thinking if sun disappear then we would be seeing the moon for a whole day but don't forget, moon don't have it's own light, it reflects the rays coming from sun if sun disappear then surely moon would be like a ball kept in dark.It would happen for the first time if an asian man calls to someone in Europe, usually when here is night there is day and vica versa, but this time both will have same appear (night only)There's a idiom in Indian Hindi language that says "seeing the stars during the day time" which we use when we are going through something worse that we see the stars during daytime, but this time every human being on earth will see the stars during daytime, do not forget stars have their own light, they are not sun dependent.For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.Our ozon layer will have it's first leave from his duty.The bad thing is for the patients of night blindness, they will not be able to see this imaginary scene.

o Tyne here to search

Answers

Based on the Newton's laws of motion, the motion of an object is due to an unbalanced net force.

What is Force?

A force is a push or pull effect which causes a change in the motion or state of an object.

Newton's second law states that the acceleration of an object is to the net force acting upon the object, and inversely upon the mass of the object.

Thus, motion occurs when there is greater net force acting on an object.

From the diagram shown above, when a force of 3000 N is applied by the man, the boxcar does not move because the force applied by the man is less than the force on the boxcar.

The box car will move if a force greater than that on the boxcar were applied to it.

According to Newton's third law of motion, for every force, there is an equal but oppositely acting reactionary force, therefore, the net force on the boxcar is 0 N.

Therefore, the motion of an object is due to an unbalanced net force.

Sasquatch. There hope it helped :)

Sasquatch is used as a secret word. So the correct option is C.

What is meant by a secret word?

Sasquatch, also known as Bigfoot, is a big, hairy, human-like monster that some people believe to exist in the northwest United States and western Canada. The name Sasquatch comes from the Salish se'sxac: "wild men." It appears to be the North American equivalent of the mythological Yeti, or Abominable Snowman, that inhabits the Himalayan area.

Many claims that the first set of Sasquatch footprints was found in 1811 by the British explorer David Thompson. Since then, hundreds more purported prints have been shown. The tale has also been aided by reports of sightings visually and even supposed photos and films (most notably those by Roger Patterson in Bluff Creek, California, in 1967), however, none of the reported proof has been independently authenticated.

The description of the sasquatch varies, but it is typically characterized as a primate that is 6 to 15 feet (2 to 4.5 meters) tall, standing upright on two feet, frequently releasing an unpleasant odor, and either traveling silently or crying out loud. Up to 8 inches (20 cm) in breadth and 24 inches (60 cm) in length, footprints have been recorded. Although most scientists are unaware of the Sasquatch's existence, a Soviet scientist named Boris Porshnev proposed that the creature and its Siberian equivalent, the Almas, may be extinct Neanderthals.

Therefore the correct option is C.

Explanation:

The new moon, for the most part, does not pass in front of the sun during new moon, but rather passes close to it in our sky. That's why there aren't any solar eclipses in most months. Because the new moon stands between the Earth and the sun, its shadow side faces Earth, rendering it invisible.
