Answer:
1. While Biology is the study of living things, living things themselves are made up of chemical composition. Our survival is dependant on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.
2. 170 pm is the radius of a Carbon Atom.
3. The vast majority of the mass of an atom is concentrated in its nucleus
4. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.
5. Neutrons are located with protons in the nucleus; they too exchange mesons with protons and with each other to form the strong nuclear force, but they do not have to overcome the repulsion from Coulomb forces since neutrons are not charged.
Soil structure is important becuse it does affect the characteristic of soil.
this is how particles are arrange in different type of soil
Sand soil:particles are very loose,it does not rentent water or nutrients,lack humus
clay soil:very packed particles,becomes water logg,rich in nutrient and humus.but is not aerated
Loamy soil is not packed in particles but is kind of in between
The first mouse was made out of wood
Answer:
B. Thermal energy will move from the plate to the fruit pop.
