James is making models of plant and animal cells using objects supplied by his teacher to represent organelles. For one cell, he
will place the objects in a shoebox. First he fills a balloon with water and places it in the shoe box. He also drops a handful of marbles into the box. Which statement most likely describes the structures he has represented so far? A. He is making an animal cell. The box is the cell membrane, and the balloon represents the large vacuole. The marbles are the endoplasmic reticulum.
B. He is making a plant cell. The box is the cell wall, and the balloon represents the large vacuole. The marbles are the tiny ribosomes.
C. He is making a plant cell. The box is the cell wall, and the balloon represents the nucleus. The marbles are the centrioles.
D. He could be making either a plant or animal cell. The box is the cell wall, and the balloon represents the large vacuole. The marbles are the centrioles.
The plant cell is a eukaryotic cell that has a cell wall outside of its cell membrane that distinguishes it from the animal cell. It has many cell organelle one of them is large vacuole that plays a role in storage for food whereas in animal cell vacuoles are small in size but has a similar role. The ribosomes are scattered in the cell in a plant cell.
So, James represented the plant cell where the box is cell wall, the balloon is vacuole and marbles are the centrioles.
Genetic engineering is the process of cutting DNA into fragments and inserting the fragments with a desired gene into another organism of the same or different species
When absorbed energy is released back into space, Earth cools. Many factors, both natural and human, can cause changes in Earth's energy balance, including: Variations in the sun's energy reaching Earth. Changes in the reflectivity of Earth's atmosphere and surface.
