Answer:

A. The model shows the process of endocytosis.

B. The process shown in the model requires energy from the cell.

Explanation:

The model shows endocytosis process. It is an active process i.e. it requires energy from the cell. In endocytosis particles like whole cells or part of cells are engulfed by another cell. Cell membrane plays an important role in this process. It invaginates to form a pocket around the incoming particle. This pocket is pinched off and the particle is contained in the newly formed vacuole from the cell membrane.

Endocytosis can be of two types, phagocytosis and pinocytosis. In phagocytosis, large particles like cells are taken in by the cell. In pinocytosis, cell takes in small solutes dissolved in extracellular fluid.

Answer:

The correct answer is - oxygen.

Explanation:

The experiment of a test tube and elodea plant in which a plant of elodea is placed in a test tube filled with water and exposed to the sunlight and one is placed in the dark. The plant that is exposed to the sunlight starts forming a gas that can be seen as bubbles in the test tube.

This experiment shows the process of photosynthesis that converts sunlight into glucose with the help of carbon dioxide and water and produces oxygen as a byproduct that releases from the plants.

Thus, the gas that forms in the test tube in the form of bubble is oxygen which is released in the process of photosynthesis.

Arisa [49]

True, the vitreous humor is a clear, watery fluid that helps maintain the intraocular pressure of the eye and provides nutrients for the avascular lens and cornea.

Vitreous humor is also known as aqueous humor or vitreous liquid. The word vitreous means transparent, and humor means liquid. It is a clear jelly-like substance that fills the inside of the eyeball. As a person ages, the vitreous humor becomes more liquid. It plays an important role in providing metabolic nutrient requirements of the lens, coordinating eye growth and providing support to the retina.

The cornea helps our eyes to focus light so we can see clearly. It is the transparent and front part of the human eye that covers the iris, anterior chamber, and pupil, along with the anterior chamber and lens.
