Answer:
Protists help break down dead material and help produce oxygen
Explanation:
I just took the quiz on k12
I can't read the paper, so all I can say is read Darwin's Survival of the Fittest and you will understand evolution.
The answer is A. The main driver of the convention in atmospheric
circulation is the suns energy. When the sun heats the earth, the atmosphere directly below the sun gets heated more
and faster compared to other regions causing an area of low pressure. This hot
air mass rises and is replaced by cooler air masses (from high-pressure regions)
from neighboring regions. This, essentially,
causes winds and air currents.
Answer:
If both parents have sickle cell anemia then the individual will be effected with
sickle cell anemia disease.
Explanation:
It is genetic disease which run in a famalies in an autosomal way.If one parent have sickle cell anemia and other dont then the pregnacy will have 25% of risk and if one Parent have a sickle cell anemia and other have sickle cell trait then the pregnancy will have 50% of chances to be effected.A person having sickle cell trait is that who is not effected with sickle cell anemia and dont have the symptoms of disease but in future if the other parent also have same trait then the pregnancy will be effected.Sickle cell anemia triat is having gene S while normal person have Beta gene.
This disease is common in african desents.
Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .
Most of the mass of an atom is concentrated at the center of the nucleus.
Atoms are made up of three subatomic particles called
1. Protons
2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
