Facilitated Diffusion
Facilitated diffusion is the type of diffusion in which the molecules are transported across the channels with the help of transport molecules. Facilitated diffusion is the answer.
What are types of facilitated diffusion ?The types of facilitated diffusion are carrier protein transport and the ion channel transport proteins.
In the process of the facilitated diffusion various molecules are diffused across plasma membrane with help from the membrane proteins such as the channels with carriers. A concentration's gradient lives for these molecules such that they all have potential in order to diffuse in (or out of) cell by just moving down it.
Facilitated diffusion thus allows polar with the charged molecules such as the carbohydrates, amino acids , nucleoside and the ions for crossing the plasma membrane. Two main classes of the proteins that helps facilitated diffusion are generally described as : carrier proteins and the channel proteins.

what is the role of tropomyosin in skeletal musle
It is a protein that prevents a muscle contraction by wrapping around it
Tropomyosin is a protein in skeletal muscle that regulates muscle contraction by covering and uncovering myosin-binding sites on actin filaments. It uncovers these sites when calcium ions bind to the troponin complex, allowing muscle contractions to occur. Without ATP and calcium, tropomyosin returns to its state covering the sites, leading to muscle relaxation.
Explanation:Tropomyosin is a protein located in skeletal muscle that has a crucial role in muscle contraction. It winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin, effectively stopping premature muscle contraction. When muscle contraction is needed, calcium ions bind to troponin, a protein complex, and cause a change in shape that moves tropomyosin away from the myosin-binding sites.
This movement allows myosin to bind to actin and forms a cross-bridge, initiating muscle contraction. The cycling of cross-bridge formation and breakdown, powered by adenosine triphosphate (ATP), leads to muscle contraction. This process continues until calcium ions and ATP are no longer adequate, at which point tropomyosin returns to its position covering the myosin-binding sites, and the muscle relaxes.

how do you ecologists measure the population density
Ecologists measure the population density by using the Quadrat method and the Mark and Recapture method.
Answer:
They use the method of marking and recapture.
Explanation:
The method of marking and recapture is the most common way that ecologists use to measure population density. To carry out this method, scientists must remove some members of the population and mark them in some way, so that they can be identified later. After correctly marking them, the members return to their original population, where they will mix with the other members of the population for a period of time determined by the ecologist. The important thing is that this time is enough for the marked members to mix with the rest of the population. While waiting for that time to pass, ecologists continue to capture and mark other members of the population until the recapture of the first marked members takes place. In this way, the size of the population will be estimated through the proportion of catches.

Rebekka notices a huge crack in a large boulder in her garden she realizes the crack was caused by Frost wedging place the steps of the Frost wedging process in order
A. The freeze-thaw cycle continues to deepen the crack until the rock splits into 2 pieces
B. Rain water is stored in rock and seeps into a hairline crack during a rainfall
C. Because ice occupies more space than water, the ice wedges the crack open
D. Rainwater in the rock crack freezes into ice
E. The temperature falls below 0° Celsius
The correct order is:
B. Rain water is stored in rock and seeps into a hairline crack during a rainfall;
E. The temperature falls below 0° Celsius;
D. Rainwater in the rock crack freezes into ice;
C. Because ice occupies more space than water, the ice wedges the crack open:
A. The freeze-thaw cycle continues to deepen the crack until the rock splits into 2 pieces;
The water from the rain gradually manages to weather parts of the rock. As it does, small cracks appear in it. Once there's cracks, the water from the rainfall also starts to store inside the rock. When the colder period of the year comes, and the temperatures fall bellow 0°C, the stored water freezes. The ice starts to spread inside the crack, thus creating pressure inside the rock. As the pressure is becoming bigger and bigger, the rock will eventually crack into two or more pieces.
Answer:
Rain water is stored in rock and seeps into a hairline crack during a rainfall: It is probable that this rock had small fissures, by where the rain water infiltrated and was stored there.
The temperature falls below 0° Celsius: As previously stated, frost only occurs when the temperature of a region falls below 0 °C
Rainwater in the rock crack freezes into ice: At such a low temperature, the water present in the cracks of the stone froze
Because ice occupies more space than water, the ice wedges the crack open: When the water froze, it turned to ice and expanded in size. Ice takes up more space than water, so ice forced the small cracks in the stone to crack.
The freeze-thaw cycle continues to deepen the crack until the rock splits into 2 pieces: The freezing causes the ice to expand more and more and this deepens the cracks in the stone.
