Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity

Explanation:

Hydroelectric power is generated from free falling water through a river channel.

The flow of water at a high speed creates water current and the kinetic energy of the water movement spins turbine attached with a generator. This produces a rotating energy which spins the generator and the coil inside.

The magnetic spinning of coiled wire inside the generator produces electric current which is then stored and transmitted through electric power grid lines to supply electric current.

Write a five paragraph essay focused on four different adaptations that hominids obtained over the last 6 million years.
Valentin [98]

Answer:Which is an adaptation?

Adaptation is the evolutionary process where an organism becomes better suited to its habitat. This process takes place over many generations. It is one of the basic phenomena of biology. ... Adaptation occurs because the better adapted animals are the most likely to survive, and to reproduce successfully.

What are the benefits of biodiversity to humans?

A healthy biodiversity provides a number of natural services for everyone:

Ecosystem services, such as. Protection of water resources. Soils formation and protection. ...

Biological resources, such as. Food. Medicinal resources and pharmaceutical drugs. ...

Social benefits, such as. Research, education and monitoring.Adaptation involves coping not only with the physical abiotic environment (light, dark, temperature, water, wind), but also with the complex biotic environment (other organisms such as mates, competitors, parasites, predators, and escape tactics of prey).

if the stimuli are delivered to the contracting muscles more frequently and ther is no time for relaxqtion
Mamont248 [21]

If the stimulus frequency is so high that the relaxation phase disappears completely, contractions become continuous in a process called complete tetanus.

What is tetanic contraction?

  • When the motor neuron that innervates a skeletal muscle generates action potentials at an extremely rapid rate, a persistent muscular contraction known as a tetanic contraction is induced.
  • A motor unit has experienced its motor neuron's maximum stimulation during this state, which lasts for a while. This happens when several impulses with a high enough frequency excite the motor unit of a muscle.
  • Every trigger results in a twitch. A slow enough stimulus delivery will cause the muscular tension to release between each succeeding twitch. High frequency stimulation will cause the twitches to overlap, which will cause tetanic contraction.

masya89 [10]

Answer:

1. E.coli

2. Intestinal tract

Explanation:

E.coli bacteria are useful to humans when they live in the large intestine of humans. The large intestine is an important digestive structure as it is important for the reabsorption of the nutrients.

The E.coli living in the intestine use the available digested nutrients and synthesises the vitamin B and K which are absorbed and utilised by the human body.

Thus, E.coli and Intestinal tract is correct.
