c) Assume that the concentration of the solute molecules varies over time on both sides of the membrane and that the solute molecules continue to pass through the membrane even when the concentration gradient is the reverse of the gradient shown. Describe the environment in and around the cell, as shown in the diagram, and the mechanism of transport of the solute molecules. (3 points)
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.

A. The power he used to move the boxes can be found by determining the rate at which work was done on the boxes.
B. The power Chad used to move the boxes is the force he used times the distance he moved them.
C. The power of the light Chad turned on is the amount of energy changed from electricity to light.
D. The power of the light Chad turned on is the amount of energy transferred per time.
2)Raul dug a hole in his yard to repair a water pipe. It took him 2 seconds to apply a force of 50 Newtons to push the shovel 0.25 m into the ground. How much power was used?
A. 0.01 watts
B. 6.25 J/s
C. 25.00 N•m•s
D. 100.00 watts
Answer:
1.) A and D
2.) B
Explanation:
The power he used to move the boxes can be found by determining the rate at which work was done on the boxes. The power of light Chad turned on is the amount of energy transferred per time. So the correct options are A and D. In 2nd, the power used was 6.25 J/s. So the correct option is B.
What is power?
The watt, denoted by the letter W, is the common unit used to measure power. James Watt, a Scottish businessman and inventor, is honoured with the unit's name. The watt is certainly a term you frequently encounter in daily life. Electrical devices like light bulbs and stereos commonly advertise their power output in watts. One watt is equivalent to one joule of work performed each second by definition.
Horsepower is another power unit that is still extensively used. This was first used to describe the ability of a regular horse to spin a capstan in the 17th century and is often represented by the sign hp. Since then, a metric horsepower has been defined as the force needed to raise a 75 kg mass a metre in one second, where 75 kg is the mass's weight in kilogrammes.
Therefore, for 1) the correct option is A and D and for 2) the correct option is B.

Why is it important for cells of multicellular organisms to undergo mitosis? A) mitosis allows for reproduction B)mitosis increases variation within an organism. C) mitosis produces cells that are different from the original dividing cell. D)mitosis produces cells that are identical to the original diving cell
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.

1. Was the restoration project effective? Explain why or why not, supporting your answer with information from your data tables and graphs. 2. Why was counting the number of species in the area important? In your answer, consider the effect a mangrove habitat has on biodiversity. 3. After five years, the average height of each mangrove species was also measured. Did this information help you better evaluate the success of the restoration project, or did it change your mind? Explain your reasoning.
Answer:
1- Yes the restoration was effective because the north beach seeds were replant and in 5 years there was almost 100% regrowth of mangroves. After five years, the average height of each mangrove species was also measured.
2- Yes the counting the number of species in the area was important because it helped figure out how much the storm damaged each beach and it showed how the animals were affected. The effect a mangrove habitat has on biodiversity is by giving animals a home, a place to sleep and shelter.
3- Yes, after five years, the average height of each mangrove species was also measured which helped realize that the restoration project was a success.

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.

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 -
During extreme starvation when all carbohydrates and fats in the body are used up.The respiratory quotient (RQ) of proteins - 0.83–0.9.Carbohydrates-
The major respiratory substrate is in form of glucose or carbohydrates in cells.The respiratory quotient (RQ) of carbohydrates - 1.Fats-
used only if carbohydrates are in short supply. It yields almost twice as much energy as carbohydrates generally do not use.The respiratory quotient (RQ) - 0.71Thus, carbohydrates like glucose and sucrose are probably the two most common organic molecules that organisms require to produce short-term energy from cellular respiration.
