Answer:
1. Newton believed that gravity was a force.
3. The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Explanation:
Law of gravitation states that force is directly proportional to masses of objects and inversely proportional to the distance between from their center. Directly means if mass increases, force of attraction also increased while inversely means if distance decrease between objects, force of attraction is also increased. Gravity is measured in weight because weight ia a force which attracts things towards its center.
The given blank can be filled with enzymatic molecules.
Enzymes refer to biological molecules or proteins, which function as catalysts and assist the composite reactions to take place everywhere in life. The enzymes generally end with the suffix - ase. For example, proteases, which functions to dissociate the peptide bonds between the amino acids.
Enzymes are big molecules, which accelerate the rate of chemical reactions within the cells, and like all other kinds of proteins, they comprise lengthy chains of amino acids.
Answer:
Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis).

Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
Answer: Pulmonary edema
Explanation:
Pulmonary edema is the condition in which there is an excess of fluid in the lungs. This fluid gets collected in the air sacs which causes hindrance in breathing.
Most of the heart related diseases causes pulmonary edema. Pulmonary edema can be caused due to pneumonia, trauma in the chest wall and exercising at higher elevations. It is very fatal if not cured on time.
Hence, the correct answer is pulmonary edema.
