The myosin head obtains the energy required for activation from the hydrolysis of ATP. This molecule contains high-energy phosphate bonds.

Adenosine triphosphate (ATP) is a nucleoside triphosphate used to carry out many cellular processes.

ATP is also one of the nucleotides used during transcription to generate an RNA strand (ofter mRNA).

Myosin is a motor protein that converts chemical energy (ATP) to mechanical energy and thus produces a given movement.

Answer:

Suppose you were to compare a milliliter of water near the boiling point with a bathtub full of water at room temperature. The bathtub contains a billion times as many water molecules, and therefore has a higher total kinetic energy and more heat.

Explanation:

A bathtub at 100°F has more thermal energy than a bathtub at room temperature.

Thermal energy is the energy that an object possesses due to the motion of its particles (atoms and molecules). The higher the temperature of an object, the more kinetic energy its particles have, resulting in greater thermal energy.

In this scenario, comparing a bathtub at room temperature (which is typically around 68-72°F) to a bathtub at 100°F, the bathtub with water at 100°F has higher thermal energy. The reason is that the water molecules in the warmer bathtub are moving more rapidly than in the cooler one. They have greater kinetic energy and are vibrating more vigorously, contributing to a higher thermal energy content.

Even though the absolute temperature difference might not seem large (32°F), the increase in thermal energy is significant due to the exponential relationship between temperature and kinetic energy. As the temperature rises, the molecules' energy increases exponentially, resulting in a notable difference in thermal energy.

In conclusion, the bathtub with water at 100°F has more thermal energy compared to the bathtub at room temperature due to the higher kinetic energy and faster motion of water molecules at the higher temperature. This concept underscores the connection between temperature and thermal energy in understanding the behavior of matter.

Clouds move faster on the Greenland regions as compared to equator.

The speed of cloud depends on the type of cloud and the wind flowing in that region. If the wind blows at higher rate and the cloud is lighter then the cloud will move with higher speed.

While on the other hand, more heavy cloud and low speed of wind leads to the lower speed of cloud in that region so we can conclude that wind speed and type of cloud are the factors that affecting speed of cloud.

The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the length-tension relationship of the thick and thin filaments to know the tension.

It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.

Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.

Replication

Explanation:

The process that copies DNA is called replication. Replication involves the production of identical helices of DNA from one double-stranded molecule of DNA. Enzymes are vital to DNA replication since they catalyze very important steps in the process.

Explanation:

Answer:

Clade 4 was derived from clade 2.

Explanation:

Answer:

This element is carbon.

Explanation:

You might be quick to think the answer is something like hydrogen and oxygen because both form to make water. But understand that the question is not asking about important elements in life, just which element makes up organic molecules. This element happens to be carbon.

It's important to understand that carbon is lucky in that it has 4 valence electrons and is able to bond with other important elements, like F, N, and especially H. The bond between C-H is essential in organic chemistry because it represents the structure of an organic molecule and helps with the IUPAC naming of organic molecules. It also suffices to say that there is a cycle for carbon in the carbon cycle, which transports carbon from one place in our world to the other.

So, it suffices to say that carbon is in fact essential for making up organic molecules.

Based on this information, this distinctive feature most likely represents a character that spread from an ANALOGOUS character. They are present in unrelated species.

An analogy is a structure observed in unrelated species that emerged as a consequence of adaptation to similar environmental conditions.

Analogous structures often exhibit the same function but they do not have a common evolutionary origin.

Conversely, homo-logies are structures that may or may not have the same function but they are present in a common ancestor.

Genetically modified and engineered organisms are that can produce the gene and the product of interest when modified. Escherichia coli is a transgenic organism.

A modified organism through the genetic and molecular pathway alteration is called a transgenic organism. Various techniques are employed to alter the genetic mechanism of the organism.

They are prepared by inserting a genetic fragment of interest from some other species by the method of recombination technology and genetic engineering.

The organism in which the insertion and the alteration are done to produce the product of interest are transgenic. Here E.coli get altered by the insertion of the human insulin-producing gene.

Therefore, option C. transgenic organism is correct.

Planets rotate and revolve around the sun in fixed orbits and are at a specified distance from the sun. The planet's orbital period will be 4.6 years.

The time taken by the planet to complete one revolution around the sun in their fixed orbits is called the orbital period of the planet.

The period can be determined using Kepler's third law:

[tex]\rm T^{2} = \dfrac{4\pi ^{2}}{GM}\times a^{2}[/tex]

Where,

Substituting values in the above equation:

[tex]\begin{aligned}\rm T&= \sqrt{\dfrac{4\pi ^{2}}{6.67\times 10^{-11}\times 6.96\times 10^{30}}\times (6.28\times 10^{11})^{3}} \\\\&=145,128,196\;\rm seconds\end{aligned}[/tex]

Therefore, 4.6 years is the orbital period of the planet.

Upon reaching the threshold for an action potential, the next step in its generation is the opening of _sodium (Na)_ channels. The correct answer is sodium,

The occurrence of action potential requires the existence of active voltage-dependent channels to open and close in response to the membrane depolarization.  

When depolarization reaches and supers the threshold point, voltage-dependent Na+ channels open and the ion gets into the cell.

The entrance of Na+ decreases the electric charge difference between the cellular interior and exterior. Membrane depolarizes and produces the action potential that tends to reach a potential equilibrium for Na+ = +60mV.

The higher the Na+ input is, the greater is the depolarization and the greater is the Na+ permeability.

Once Na+ channels are closed, voltage-dependent K+ channels open, increasing the membrane permeability to the ion, letting K+ get out of the cell, following the electrochemical gradient.

The closure of Na+ channels and opening of K+ channels are responsible for membrane repolarization.
