given that cells have a rmp, what 2 additional proteins are required to produce an action potential?

Explanation:

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) 3) Anaphase: sister chromatids are pulled to opposite poles of the cell 4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Answer:

1

Explanation:

The cell doesn't split until telophase, so there's still only one during metaphase. Chromosomes are still lining up during this phase.

DNA replication is the process through which DNA duplicates. It occurs in the interphase and involves different enzymes, DNA molecules, and free nucleotides. Terms and definitions in the attached files.

DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.

The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.

DNA strands are antiparallel, and replication occurs only in 5'-3' direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

In the attached files you will find the terms and their definitions.

A muscular organ in the chest that is slightly tipped to the left is the heart. It has four chambers: two higher chambers, the right and left atria, and two lower chambers, the right and left ventricles.

Deoxygenated blood from the body is taken up by the right atrium and pumped into the right ventricle, which subsequently pumps it to the lungs to be given oxygen. Blood that has been oxygenated by the lungs is taken in by the left atrium and pumped into the left ventricle, which subsequently pumps it to the rest of the body. The pericardium, a protective sac that surrounds the heart, connects the organ to the rest of the body by a network of blood arteries.

Two reasons why Maria has tissue ischemia are  circulatory disorders and edema. This can lead to hypoxia due to the inability of oxygenated blood to reach the tissue cells.

Tissue ischemia is a lack of blood flow to certain organs of the body which causes these organs to lack oxygen. Reduced oxygen flow in the blood can inhibit the metabolism of cells that need oxygen, because of that ischemia that occurs in the brain, heart, stomach, or limbs can be fatal.

Ischemia can occur due to edema and air circulation disorders. Edema that occurs due to the accumulation of fluid in the body parts causes the body parts to swell so that air can be obstructed. Edema usually occurs due to sitting or standing for too long. If edema occurs in the lungs, this can affect the circulation of blood flow so that oxygen that is carried to the tissues will decrease and inhibit cell metabolism.

Outer Core

Because of the weight of the melting moving metal creates energy

Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.

Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.

The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.

The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.

Therefore, Because of the weight of the melting, moving metal creates energy.

Explanation:

As the skateboarder moves, several energy transformations take place within their body. Some of the energy transformations include:

1. Chemical energy to kinetic energy: When the skateboarder pushes off the ground, the energy stored in the chemical bonds of their muscles is converted into kinetic energy, which is responsible for their motion.

2. Kinetic energy to gravitational potential energy: As the skateboarder moves up a ramp, their kinetic energy is converted into gravitational potential energy.

3. Gravitational potential energy to kinetic energy: When the skateboarder moves down the ramp, the gravitational potential energy is converted back into kinetic energy.

4. Kinetic energy to thermal energy: As the skateboarder moves, they also experience frictional forces which convert some of their kinetic energy into thermal energy.

5. Chemical energy to thermal energy: The continuous movement of the skateboarder requires the energy stored in their muscles to be converted into thermal energy, which is released as heat.

I hope that the assistance I provided was helpful.

The motion of the skateboarder is powered by energy transformations that occur within their body. As the skateboarder moves, their body converts stored chemical energy (from food) into kinetic energy, which is the energy of motion. This conversion happens through a series of complex biochemical processes that occur within the skateboarder's muscles.

When the skateboarder pushes off the ground, their leg muscles contract, converting chemical energy stored in the form of ATP (adenosine triphosphate) into kinetic energy as the legs move and the skateboarder accelerates. As the skateboarder continues to move, the muscles in their body work together to maintain balance and control, converting chemical energy into kinetic energy and potential energy as the skateboarder jumps, turns, and performs tricks.

Additionally, the skateboarder's body also experiences other forms of energy transformation during this process. For example, as the skateboarder moves, their body generates heat through metabolic processes, which is a form of thermal energy. The skateboarder also loses energy through friction with the ground and air resistance, which is converted into heat and sound energy.

In summary, the motion of the skateboarder is powered by a series of complex energy transformations that occur within their body. These transformations involve the conversion of stored chemical energy into kinetic and potential energy, as well as the generation of heat and sound energy through friction and air resistance.

Answer:

The denaturing temperature is (at least partially) controlled by the number and coordination of intra-molecular electrostatic interaction (H-bonds, stacking effects). The tertiary structure determines which H-bonds will exist - and vice versa; it is not appropriate to distinguish cause and effect here.

Explanation:

Answer: Why do proteins denature at different temperatures? Protein structures are held together by a range of interactions, including hydrogen bonds, and electrostatic and hydrophobic interactions. As the temperature increases, these bonds can be broken, and even the covalent bonds will be destroyed at high enough temperatures.

False. The new plant produced by layering does not have to remain attached to the stem of the original plant.

Layering is a method of vegetative propagation of plants in which a part of a plant such as a stem or a branch is pegged to a substrate for that part to develop its own root and establish before it is eventually cut off and transplanted to become a new plant.

Layering can be done in 5 ways. These include

Answer:

Passive transport moves molecules and ions from a higher concentration to a lower concentration without any energy while active transport does the same thing only it uses energy. Osmosis deals with the net movement of solvent molecules through a membrane with a higher solute concentration. Osmosis and active transport both work together, while osmosis does its own movement the active transport moves the dissolved solutes across a membrane against a concentration gradient.

Active transport and passive transport are almost the same they function the same only one doesn't require energy while the other one does. Hence why active transport and osmosis work well together it's because of the energy that helps transport dissolved solutes.

Hope this helped :)
