Answer:

An active site contains a binding site that binds the substrate and orients it for

catalysis. The orientation of the substrate and the close proximity between it and

the active site is so important that in some cases the enzyme can still function

properly even though all other parts are mutated and lose function.

Answer:B

Explanation:

Mesopotamia has been the Western Asian region that is known for early civilization. The method that has the least impact on the water table is the best irrigation method. Thus, option B is correct.

Mesopotamian irrigation practices have been the use of canals and shadufs for direct use in agricultural fields. They irrigated their land by digging holes and storing the water. They also built canals and connected them to the ditches.

For modern practices, the Mesopotamian irrigation system is a model as it defines the best irrigation method to be the one that has the least impact on the water content and table.

Therefore, option B. the best irrigation method is that uses the eater most efficiently and does not negatively impact the water table.

The molecules supply the main source of short-term energy used in cellular respiration is - G) carbohydrates.

All living organisms carry out cellular respiration in order to get energy for cellular processes. All biomolecules proteins, lipids, and carbohydrates provide energy by breaking down during this process. however, sugar molecules or carbohydrates are used to provide short-term and immediate energy in the form of ATP by cellular respiration.

Proteins -

Carbohydrates-

Fats-

Thus, carbohydrates like glucose and sucrose are probably the two most common organic molecules that organisms require to produce short-term energy from cellular respiration.

The best example of water regulating an organism’s body temperature is a fish passing water over its gills, which is the second option, as the fish gill maintains the body temperature and maintains the oxygen and carbon dioxide concentrations too.

The water-regulating system in an animal body maintains homeostasis in the body, such as electrolytes homeostasis, such as ions such as sodium and potassium in body fluids, and the lungs ,skin, play a role in regulating water balance through respiration and sweating to maintain temperature of the body.

Hence, the best example of water regulating an organism’s body temperature is a fish passing water over its gills, which is the second option, as the fish gill maintains the body temperature and maintains the oxygen and carbon dioxide concentrations too.

Answer:

Ichthyosaurs lived from Triassic to Middle Cretaceous approximately 250 million years ago until 110 million years ago

Explanation:

Ichthyosaurs evolved during the early Triassic period from land reptiles. This group was characterized by a spindle-shaped body, a shoulder girdle connected to a streamlined skull, two pairs of limbs, and digit-like bones. Moreover, Ichthyosaurs drew oxygen from the atmosphere (i.e., like marine mammals). Utatsusaurus is the oldest known Ichthyosaur species and it lived during the Lower Triassic. ln the same way to the land reptiles, Utatsusaurus had a pelvic girdle attached to the spine, and an equal length between the humerus and femur.

Answer:

Does the movement of molecules stop when the concentration of a solute is equal on both sides of a membrane?

The concentration of solute molecules on both sides of the membrane will vary over time, and the solute molecules will continue to pass through the membrane even when the concentration gradient is reversed.

The environment in and around the cell is constantly. The diagram shows a cell with a higher concentration of solute molecules on the inside than on the outside. This means that there is a concentration gradient, and the solute molecules will tend to move from the inside of the cell to the outside. This process is called diffusion.

The solute molecules can also move through the membrane by other mechanisms, such as facilitated diffusion and active transport. Facilitated diffusion is a process that uses proteins in the membrane to help the solute molecules move across the membrane. Active transport is a process that requires energy to move the solute molecules across the membrane.

The concentration of solute molecules on both sides of the membrane will continue to change over time. As the solute molecules move from the inside of the cell to the outside, the concentration of solute molecules on the inside of the cell will decrease. This will create a new concentration gradient, and the solute molecules will continue to move from the inside of the cell to the outside.

The answer is A mitosis allows for reproduction. This is because during mitosis two identical daughter cells are created which can contribute to an embryo.

Hope this helps ! <3

It is important for cells of multicellular organisms to undergo mitosis because mitosis produces cells that are identical to the original dividing cell. Thus, the right option would be D.

Mitosis involves the division of vegetative cells and it results in daughter cells with the same morphology and genome as the parent cell.

The division of vegetative cells in multicellular organisms will ensure that damaged or dead cells are replaced with cells of similar morphology and genome.

Apart from replacing dead or damaged cells, mitosis also allows multicellular to grow in size by allowing similar cells to spring from existing cells.

Answer: Place each oil stain on separate, but identical, pieces of cloth.

The group of students should have stained separate but identical pieces of cloth.

There are different factors that influence how easily a stain will come out of a material such as:

Assuming the temperature is held constant and the type of detergent is being tested, the only thing other thing to control is the type of material.

The students used separate cloths instead of identical ones which meant that a significant variable was not controlled.

In conclusion, the students should use separate but identical pieces of cloth so that the type of material would not impart their experiment.
