When particles were pulled together so tightly they combined.
<h3><u>Explanation</u>;</h3>
- The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas.
- It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.
- According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust.
Answer: due to insufficient exocytosis in the type II alveolar cells
Answer:
1 .Atom goes to C
2.Proton goes to A
3. Neutron goes to b
Question 4:Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron
Question 5:Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus.
Question6:Thomson's model of the atom in 1897 shows that the atom was a sphere of matter, wherein the electrons are mixed inside it. This model does not show the protons and the neurons. On the contrary, the current model that was proposed by Niels Bohr gives us a clearer representation of the structure of an atom.
Question 7:its mass number A is 23.
Question 8: 1 i found the number because hydrogen only has 1 atom so yuh..
I will answer the rest in the comennts:)
Explanation:
The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.
If 1% sugar solution is placed in pure water, then there would be a higher concentration of water molecules outside the cell compared to inside the cell. The solution outside the cell would be hypo-tonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.
ATP contains energy in the chemical bonds between its phosphate groups, <span>best explains how the structure of ATP helps provide energy to the cell.</span>
