The binding of oxygen to hemoglobin differs from the oxygen binding behavior of myoglobin because

Answers

The binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin because oxygen binding to hemoglobin is cooperative.

Hemoglobin - oxygen binding

Hemoglobin is the oxygen carrying protein of the blood that is located at the red blood cells. They have high affinity for oxygen.

Myoglobin is found in the muscle cells and they are contain haem proteins which they used to transport and store oxygen in the muscles.

Hemoglobin and myoglobin are two types of globin proteins that serve as oxygen-binding proteins, but binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin.

This is because binding of oxygen by hemoglobin is cooperative. This means that as hemoglobin binds successive oxygens, the oxygen affinity of the subunits increases. This is opposite for myoglobin.

Which element is essential to making up all organic molecules?.

Answers

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.

Which statement accurately describes the relationship between cytokinesis and mitosis? Mitosis includes interphase and cytokinesis. Cytokinesis precedes mitosis in the cell cycle. Cytokinesis is not a phase of mitosis, but occurs during mitosis. Interphase includes cytokinesis and mitosis.

Answers

Mitosis is a type of cell division that produces two alike daughter cells. Cytokinesis is not a phase of mitosis but happens during mitosis.

What are cytokinesis and mitosis?

Mitosis is a cell division type that divides the parent cell and the genetic material into two alike daughter cells with the same chromosome numbers.

Cytokinesis is a process by which at the end of the telophase the cytoplasm of the cell starts dividing and results in the formation of the plate in plants and furrows in the animal, dividing the cell equally.

Therefore, option c. Cytokinesis is not a phase of mitosis but occurs during mitosis.

what have more thermal energy?a bathtub at room temperature or a bathtub at 100° F ?

Answers

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.

Explanation:

Invasive species when introduced compete with the native species present in the environment for food and space. One such example of invasive species is Invasive carp.

What is adaptation?

Adaptations are the changes in an organism which help them in adjusting more in an ecosystem. Adaptations can be of different types such as structural, physiological, etc depending upon the environment.

When a highly invasive species is introduced, they are more likely to compete with the native species present in the environment. When the population sizes and genetic diversity of native species are large enough, the native species may be able to evolve traits which allow them to co-occur with the invasive species and live in the same ecosystem.

One examples of invasive species is the Invasive carp, which are fast-growing, aggressive, and adaptable fishes that outcompetes the native fish species present in the waterbody for food and habitat in much of the mid-section of the United States.
