In cell division, the cell that is dividing is called the parent cell. the parent cell divides into two daughter cells. the process than repeats in what is called the cell cycle. cells regulkate their division by communicating with each other hope it helps,if you need help just ask and i will be more than happy to help. :)
Answer:An explosion disturbs the gas and dust in the nebula.
Explanation: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula . Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed. Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges. As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons . Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat. Icy matter settled in the outer regions of the disk along with rocky material, where the giant planets like Jupiter formed. As the cloud continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites , which are thought to be left over from this early phase of the solar system, scientists have found that the solar system is about 4,600 million years old!
Answer:
The correct option is A. They provide the energy required to build high-energy sugars.
Explanation:
Calvin cycle can be described as the series of dark reactions of the process of photosynthesis.
During the Calvin cycle, carbon dioxide is reduced to glucose. The molecules of NADPH and ATP play an active role in this reaction to occur. The molecules of ATP serve as a source of energy. Whereas, the molecules of NADPH serve as a reducing agent. Electrons are added by NADPH so that carbon dioxide gets converted into glucose.
Answer:
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
Explanation:
Red colored cars are more dangerous than other colored cars because red color cars can not be seen in the evening or dark environment so that's why more accidents were observed with red color cars as compared to another color cars. Red is a vibrant color and one of the most dangerous cars colors. People sometimes confused with traffic lights, brake lights etc and accident happen.
The right answer is B.
Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.
Glycogen, which is a polysaccharide, is the form in which carbohydrates are stored in the body (animals and fungi). Glycogen is broken down into glucose molecules when the body needs energy.
