Because it is catalyst which speeds up or slows down the speed of the chemical reaction without being changed or used up
<span>Turgor pressure (hydrostatic pressure) of the plant can be described as the force within the cell that pushes the plasma membrane against the cell wall. Turgor pressure within plant cells is regulated by osmosis (travel of the water from an area with a low concentration of solutes, to one with a higher-solute concentration). There are two mechanisms for the regulation of turgor pressure.</span>
<span>1. The semipermeable membrane, which only allows some solutes to travel in and out of the cell. Also, it can maintain a small amount of pressure.
</span> <span>2. Transpiration by opening and closing of stomates to control evaporation from leaves<span>, which results in water loss and decreases turgidity in cells.</span></span>
Answer:
diverse proteins embedded in a phospholipid bilayer
Explanation:
According to fluid mosaic model the cell membrane is made of bilayer of phospholipid. Many proteins are embedded in this bi layer. Carbohydrate and cholesterol are also found in different forms. Carbohydrate can either be attached to the embedded protein in which case it is called as glycoprotein or it can be connected to the lipid molecule in layer and called as glycolipid.
Proteins can be found in two forms too. They can either be embedded in the layer i.e. they can penetrate single or both layers. These proteins are called as integral proteins. They can also be present on one side of the membrane and not penetrate the lipid bilayer in which case they are called as peripheral proteins.
Answer:
b
Explanation:
<em>The correct answer as to the ocean process that exposes the coastal organisms to land-based predators would be the daily tidal patterns that leave the coastal area exposed to the land for a part of the day.</em>
Some parts of the coastal areas become exposed to land during certain periods of the day as a result of tidal waves. When this happens, the aquatic organisms occupying these coastal areas become temporarily exposed to land predators who hunt and kill them for food.
<u>Therefore, the correct option is b. </u>
