a skeletal muscle generates the greatest tension when it is:

Answers

Explanation:

A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated

Skeletal Muscle generates the greatest tension when the muscle is stretched to an intermediate length, by length-tension relationship.

How tension generates in skeletal muscle?

Muscle tension is highest in skeletal muscles when stretched to an intermediate length, as indicated by the length-tension relationship.

When skeletal muscle fiber contracts, myosin heads link to actin to create cross-bridges, and the thin filaments slide across the thick filaments as the heads pull the actin, resulting in sarcomere shortening and muscular contraction stress.

The amount of stress produced by a muscular contraction is determined by two factors: the number of active muscle fibers and the frequency of neural stimulation of the muscle fibers.

Therefore greatest tension generates in skeletal muscle when it is stretched to the intermediate length.

Which of the following steps is required to break down pharmaceuticals, pesticides, and heavy metals in wastewater?

Aeration open basins
Chlorination and ozonation
Biological nutrient removal
Grit and bar screening

Answers

In order to remove the listed substances from wastewater, processes such as Chlorination and ozonation are most often used.

Chlorination is a process used in the purification of wastewater in order to achieve clean water that may be used for consumption or other uses. The process of chlorination exposes the wastewater to chlorine in an attempt to eliminate bacteria, viruses, and other potentially harmful substances and organisms from the water.

Much like chlorination, ozonation is a similar process used to purify wastewater. In contrast to the previous method, however, ozonation exposes the water to ozone. Though ozonation is safer and much more effective, these processes are often used together to eliminate harder to tackle elements such as

If the area had experienced a wet season two years after the drought instead of a dry season,
what kind of evolution would you expect? Explain your answer.

Answers

The organisms will start adaptation to that environment in order to survive.

If the area had experienced a wet season for two years after the drought instead of a dry season then we expect that the organisms that lives in that environment will start adaptation to that humid environment in order to survive.

What is adaptation?

Adaptation occurs when an organism adapts certain actions to a certain environment in order to live more comfortable. If the organism do not adopt certain features then it will be extinct from that environment while on the other hand, those organism which adopt certain features will be able to survive so we can conclude that the organisms will start adaptation to that environment in order to survive.

termination of transcription in bacteria occurs when ________.

Answers

RNA polymerase

Termination of transcription in bacteria occurs when the RNA polymerase encounters specific DNA sequences that lead to stalling of the polymerase. This results in release of RNA polymerase from the DNA template strand, freeing the RNA transcript.

Transcription is the process of synthesizing the RNA transcript from DNA.

The termination of transcription in bacteria occurs when RNA polymerase comes in contact with some particular terminator sequences that stalls the RNA polymerase letting it fall off.

In transcription, there is its initiation (start) and its termination (and end). Unlike humans with stop codons that terminates the process, the bacteria uses a terminator sequence which it transcribes and cause its fall off the DNA and releasing the RNA transcript.

Comets, Asteroids and metoeorites support the hypothesis that earth and the rest of the solar system was formed by a condensing nebula.

What are the functions of asteroids?

An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.

They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron).

Almost all of the asteroids in our solar system are orbiting in a broad band 19,400,000 miles wide between Jupiter and Mars. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade.

Answers

Answer:

r

Explanation:

I think its B? Can someone explain it to me tho

Answers

Explanation:

I think it should be C because increase in temperature increases molecular motion. Therefore the speed of the moving molecules of both enzymes as well as the substrate will be accelerated. This

will enhance the colliding probability for both enzyme active sites and substrate molecules and more collisions occur between the enzyme active sites and substrate molecules generate greater chances for the reaction to occur. This can continue up to a certain point, after which there is a rapid decline in enzyme activity. This point is referred to

as optimum temperature. When the temperature increases beyond the optimum temperature, the hydrogen bonds, ionic bonds and other weak chemical bonds of enzyme active sites may be disrupted.

This will result a change in the shape of the active site of enzyme which will alter the complementary nature of the active site of enzyme molecules. Therefore, the

complementary binding of enzyme active sites and substrate molecules will be prevented. The above event is called as denaturation of enzyme molecules.

Therefore the rate of enzyme catalyzed reaction or in this case, photosynthesis will start to decline when the temperature increases beyond the optimum temperature and stops completely at certain

temperature, although rate of collision will keep on increasing.

True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.

Answers

It is true that it is possible for a population to not evolve for a while.

There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.

There are 5 Hardy-Weinberg assumptions:

no mutation random mating no gene flow infinite population size and no selection (natural nor forced).

You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.

For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.

Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.
