The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cells?endoplasmic reticulum ribosomes chloroplasts lysosomes peroxisomes vesicles large central vacuole Golgi complex cytoskeleton mitochondria cell wall
Answers
Answer 1
Answer:
Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.
Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.
Cell walls also maintain structure and rigidity.
Chloroplasts are used in the process of photosynthesis, which only occurs in plants.
What system includes the core, mantle, and crust of the Earth?
Answers
The geosphere includes all these parts. In earth science, the core is the center and the hottest part of the earth. The mantle is the next layer of the earth. The crust of the earth includes the ground that we walk on. The geosphere includes the solid parts of the earth.
Under a light microscope, a stained cell shows chromosomes lined up along the middle. What will happen next? Spindles will form and centrioles will move to opposite poles. A nuclear membrane will form around each set of chromosomes. Chromosomes will separate and move to opposite poles.
Answers
Chromosomes will separate and move to opposite poles.
A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.

During which stage of a cell's cycle do the replicated chromosomes thicken and become visible?
Answers
the cell cycle moves on the chromosomes thicken as the size of the cell grow and since became vissible!

20. Which of the following accurately describes carbon atoms? A. Carbon atoms are only found in two of the four main macromolecules. B. Carbon atoms only have three electrons available for bonding. C. Carbon atoms can bond to other carbon atoms. D. Carbon atoms can only form triple bonds with other carbon atoms.
Answers
C. Carbon atoms can bond to other carbon atoms.
Carbon stored in plants reaches the atmosphere via cellular respiration. Cellular respiration is the set of metabolic reactions that allows plants to convert the energy from nutrients into ATP (adenosine triphosphate) and then release the waste products. The energy from the glucose molecules is broken down into ATP. Water and carbon dioxide are also required to convert the nutrients into ATP. In our case, carbon and oxygen are waste products so they are released into the atmosphere via the pores underneath the leaf of a plant or tree.
