Kay [80]

Answer:

Fossil fuels are produced by the same geological processes.

Explanation:

Fossil fuels form when organic matter which has been buried in the Earth over a long period of time is subjected to heat and pressure over a long period of time. Heat and pressure are both critical components for the formation of a fossil fuel. The process of the formation of fossil fuel is the same today as it was in the past. The geological processes are the same for the formation of fossils.

What part of the rotifer is responsible for crushing food?
frozen [14]

Answer:

Rotifers are specialists at living in habitats where water dries up regularly.

The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]

The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]

Explanation:

The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.

Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.

Hydroelectric dams are often used to generate
inysia [295]

Answer:

Potential & Kinetic energy.

Explanation:

The water used gains potential energy overtime before it is converted to mechanical (or kinetic energy). This can be explained by the water having increased potential energy as it flows at an equal altitude, but converting to kinetic energy as it flows downhill, or over the dam.

This kinetic (or mechanical) energy is then converted to traditional electricity. This process is also an example of a renewable resource being utilized for everyday things (such as powering cars, homes. or charging batteries).

These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses. ______
sertanlavr [38]

Answer:

The best answer to the question: These cellular structures are utilized in strong involuntary muscle contractions and transmission of electrical impulses, would be: T-Tubules.

Explanation:

In both skeletal and cardiac muscle, not smooth muscle, because of the way that the muscle fibers are conformed into tight bundles of sarcomeres (skeletal muscle) and myocardiocytes (cardiac muscle), there is a need for a series of structures that will ensure that when there is a stimulus from the nervous systems, these stimulus will propagate to all the cells in the fibers, and not just one.

Aside from counting with a neuromuscular motor plate, which will receive the neurotransmitter from the nerve endings and produce the appropriate reactions, as well as propagate that reaction to all the cells that are being stimulated, muscle fibers also have a structure known as T-Tubules. T-Tubules are formations much like roadways of cell plasma membrane that connect not just one, but all the cells within a muscle fiber so that once a stimulus comes, all the cells will initiate the process of calcium release and action potential propagation. These T-Tubules will ensure that electrical impulses reach all muscle cells and that all cells react at the same time as needed.

A group of antelope leaving the herd in search of better grassland is an example of
PtichkaEL [24]

Answer:

emigration

Explanation:

The emigration of an animal, in this case of the antelope, is the cause of the lack of food.

The animals are in constant search of food and better places to cohabitate. Antelope is leaving its herd to find a better place for food and even if it sounds strange, animals are also behaving as individuals in case there is threatening of hunger.
