How did pasteur and Tyndall finally settle the Spontaneous Generation Controversy?
Pasteur and Tyndall finally settled the Spontaneous Generation Controversy with the experiments performed that disproved the theory.
What was the Spontaneous Generation Controversy?This was a theory that stated that life would spontaneously arise, as an attempt to explain the fungi that would grow on food and the appearance of fly larvae in meat, since the existence of bacteria was not known at the time. Pasteur and Tyndall finally disproved this theory by showing that these things do not occur when the food is isolated from the open air.
Therefore, we can confirm that through their experiments which showed that without contact with the open air, life does not arise from leftover food, Pasteur and Tyndall proved that more is needed for life to arise.

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

What are some costs of social behavior?
Answer:
Social behavior is behavior among two or more organisms within the same species, and encompasses any behavior in which one member affects the other. This is due to an interaction among those members. Social behavior can be seen as similar to an exchange of goods, with the expectation that when you give, you will receive the same. This behavior can be affected by both the qualities of the individual and the environmental (situational) factors. Therefore, social behavior arises as a result of an interaction between the two—the organism and its environment. This means that, in regards to humans, social behavior can be determined by both the individual characteristics of the person, and the situation they are in.

Helpppp pleaseee
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.
