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: D.adding more shelter for frogs
Food chain can be defined as the linear series of food and energy distribution, in which one organism is consumed by the other in order to obtain nutrient and energy.
In the given situation a person wants to reduce the mosquito population, which is present as a primary and secondary consume in the pond food chain. By adding more shelters for frogs can reduce the population of frogs as the frogs are present as tertiary consumers in the pond food chain. These frogs will feed upon mosquitoes, and limit their population.
Well Mitochondria breaks down sugar molecules to release energy in the form of APT (Adenosine Triphosphate). But Energy is released from food molecules during Cellular Respiration.
Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles. In plants the vacuoles are larger than in animals. The vacuole provides plant nourishment in the scarcity of water in the external environment hence, prevents the wilting of plants.
