<span>According to the nebular theory stars are formed in which sequence:
a. Interstellar clouds - "nebula" is a Latin word which means clouds. These clouds start to form and are composed of gases like hydrogen and helium.
b.Clumps - as the gases start to form and come together they form clumps of gases that are highly concentrated and they start to grow.
c. Gravitational forces - when clumps have grown into big sizes the gravitational forces that are found within it increases and are converted into kinetic energy of fast-moving particles that continuously bump into each other and create or generate heat.

d. Nuclear fission - as the clumps keep on colliding and creating heat (18 million degrees Fahrenheit), nuclear fission begins.
e. Outward pressure from the nuclear fission prevents the collapse of the gases, stabilizing the gases eventually creating a star. </span>
Because it’s in smaller price so therefore can’t melt faster than the block, since the smaller peices will melt at the same time as one another.
1) She developed a hypothesis 2) She put one plant near the window... 3) Every few days 4) Over six weeks
Answer:
Fresh water represents only a small part of the water resources of the Earth. the fishes present in these ecosystem have high economical values and are beneficial to mankind. The evolution of these fishes is important because it will allow genetic varieties to arise in these fishes. Hence, these fishes will be able to survive and reproduce. Also, some of these fishes might adapt to live in salty environments in the course of evolution.
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
