Muscle contraction that results in a change in joint angle is called <span>concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.</span>
Answer:
Due to structure of engine.
Explanation:
Cars and trucks today powered by petroleum products because of their engine which only works when the petroleum products are used. When the petroleum products are burn in the engine, it produces small blasts which moves the piston and as a result the wheels of the car also start movement. Petroleum products are economically cheap due to its higher availability on the earth, easily available to the people, can be easily transported are the factors that make us use of petroleum products.
<span>Poisson's ratio (ν), named after Siméon Poisson, is the ratio, when a sample object is stretched, of the contraction or transverse strain (perpendicular to the applied load), to the extension or axial strain (in the direction of the applied load).

Cardiac systole is the contraction of the cardiac muscle in response to an electrochemical stimulus to the heart's cells (cardiomyocytes<span>).

Answer:
Eutrophication
Explanation:
Eutrophication is the name given to the natural nutrient enrichment of a shallow lake, estuary, or slow-moving stream. It is caused mostly by runoff of plant nutrients, such as nitrates and phosphates, from surrounding land.
<span>Base on a study that was undertaken in order to compare the
respiratory responses of hypnotized and non-hypnotized subjects to certain
instructions. According to a study, the 16 male volunteers were allocated to a
random experimental group to be hypnotized or to a control group. Baseline
measurements were taken at the start of the experiment. Analyzing the data,
researchers noticed that the baseline breathing patterns of the two groups were
different; One explanation proposed for this unexpected experimental the
difference of the group was more excited in the anticipation of the experience
in being hypnotized.</span>
