What is the relationship between the number of motor neurons recruited and the number of skeletal muscle fibers innervated?

Biology
1 answer:
Alisiya [41]3 years ago
8 0

Answer:

Alpha motor neurons (also called lower motor neurons) innervate skeletal muscle and cause the muscle contractions that generate movement. Motor neurons release the neurotransmitter acetylcholine at a synapse called the neuromuscular junction.

Describe the three types of predation and give an example of each.
uranmaximum [27]
<span>True predation is when a predator kills and eats its prey. Some predators of this type, such as jaguars, kill large prey. They tear it apart and chew it before eating it. Others, like bottlenose dolphins or snakes, may eat their prey whole. In some cases, the prey dies in the mouth or the digestive system of the predator. Baleen whales, for example, eat millions of plankton at once. The prey is digested afterward. True predators may hunt actively for prey, or they may sit and wait for prey to get within striking distance. In grazing , the predator eats part of the prey but does not usually kill it. You may have seen cows grazing on grass. The grass they eat grows back, so there is no real effect on the population. In the ocean, kelp (a type of seaweed) can regrow after being eaten by fish.</span>

In prokaryotes new mutations accumulate quickly in populations, while in eukaryotes new mutations accumulate much more slowly.
Mnenie [13.5K]

Answer: Option A

Explanation:

In Prokaryotes the the rate of new mutations is much more as compared to the eukaryotes. The rate of accumulation of mutation is slow in case of  eukaryote because their generation is long as compared to prokaryotes.

Prokaryotes have short generation time and large population size which enables them to accumulate the mutation quickly.

The machinery is also not that complex when it comes to prokaryotes. Transduction, conjugation and tranposable elements. So, the changes during these processes leads to mutation in the prokaryotes and can be observed quickly due to their small generation.

HELP ME PLEASE! List the steps scientists for using technology to find the half-life of an isotope.​
liubo4ka [24]

For radioactive materials with short half-lives, you use a very sensitive calibrated detector to measure how many counts per second it is producing. Then using the exact same set up you do the same at a latter time. You use the two readings and the time between them to determine the half-life. You don’t have to wait exactly a half-life, you can do the math with any significant time difference. Also, you don’t need to know the absolute radioactivity, as long as the set up is the same you only need to know fraction by which it changed.

For radioactive materials with long half-lives that won’t work. Instead you approach the problem differently. You precisely measure the mass of a very pure sample of the radioactive material. You can use that to calculate the number of atoms in the sample. Then you put the sample in a counter that is calibrated to determine the absolute number of disintegrations happening in a given time. Now you know how many of them are disintegrating every second. You use the following equations:

Decays per Second = (Number of Atoms) x (Decay Constant)

Half-life = (Natural Log of 2) / (Decay Constant)

And you can calculate the half-life

Hope it helps :)

Mark it as brainliest pls :)
