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.
The groundwater is being discharged faster than it is being recharged is the data suggested.
Option D
<h3><u>Ex
planation:</u></h3>
Ground water level is the level of underground storage of water above the impermeable rock layer. The underground water is getting filtered through different layers of permeable rocks before it enters the final layer. So it’s fresh and ready to be consumed as it is taken out. Thus for centuries, it’s being used as the source of drinking water.
But with increasing population, the ground water is being consumed at the rate very faster than it can be refilled from different sources like precipitation, rivers and other water bodies. So its level tends to get lower and lower as this continues until the point it gets finished.
Answer:
a) not accompanied by purging
Explanation:
- If a person has episodes of uncontrollable eating then the person is said to have a problem of binge eating.
- When a person shows a tendency of frequent and recurring binge eating then the person is said to have binge eating disorder.
- Binge eating disorder is differentiated from another similar problem which is known as bulimia nervosa.
- In the case of binge eating disorder a person has a tendency of binge eating but without purging, unlike bulimia nervosa where purging is a characteristic feature.
- Purging is an attempt to get rid of the excess food consumed and this attempt is not made in case of binge eating.
