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.
Answer:
Water
Explanation:Water is renewable because it gets evaporated from the ocean then to the clouds, which makes it rain on the land, then the water can go into rivers and back to the ocean, water cycle
Answer:
burning gasoline is correct
Answer:
Forests. Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis
Explanation:
Plants are involved in the Carbon Cycle by absorbing Carbon out of the atmosphere in order to photosynthesize. The Carbon is used during the photosynthesis. It gets back in the environment by a plant's breathing process.
Answer:
Explanation:
Myth: Is a bigger penis better?
Truth: Penises come in all shapes and sizes. The idea that bigger is better is simply false. What really makes sex better is compatibility with your partner and open communication about what feels good and what doesn’t.
Myth: Vaginas are tight or loose depending on the amount of sex a person has had.
Truth: The “tight vs. loose” idea is fairly common, but it is purely false. The vagina is a muscle that expands and contracts. When a person is aroused, the walls of the vagina soften and lengthen, making insertion easier. If they are nervous, the walls of the vagina will naturally contract, making insertion difficult.
Myth: Sex is painful.
Truth: Sex should feel good –even if you are having sex for the first time or if you have had sex before . Feeling safe and comfortable is what’s important. If someone is nervous or tense, their muscles will contract, which may cause discomfort. If something does not feel good, tell your partner. You may need to slow down, use a lubricant or stop until you are feeling ready and comfortable.
Myth: Everyone is having sex.
Truth: It may seem like everyone is having more sex than you. The fact is everyone has different sex drives. Some people want to have sex a lot, while others are not interested in sex at all. What’s important is you are true to yourself and not worrying about what other people are doing.
