Biology
1 answer:
antiseptic1488 [7]3 years ago
4 0

Answer:

The answers are:

Cell Wall:

  1. Gives plant cell its shape
  2. Rigid

Cell Membrane:

  1. Acts like a skin.
  2. More selectively controls what goes in and out of cell.
  3. Is not rigid.

Explanation:

  • The question entails the structural and functional differences of the cell wall and cell membrane.
  • The cell wall is a rigid and strong layer that covers the outside of plant cells. It is absent in animal cells.
  • The cell wall is largely composed of cellulose, hemicellulose and pectin in plants and peptidoglycan in bacteria. The cell membrane, on the other hand, is comprised of a lipid bilayer.
  • The strong and complex network of cellulose renders the cell wall rigid; whereas, as it is made up of lipid bilayer, the cell membrane is flexible and elastic.
  • Unlike the cell membrane, which allows the movement of selective substances, the cell wall does not allow any substances to pass through.

What are 3 ways that humans can reduce the amount of waste released into the environment.
ycow [4]

Answer:

Reduce, Recycle, and Reuse.

Explanation:

Reduce your use of single-use, disposable, and non-biodegradable items. By doing that, you may be able to decrease the amount of waste you produce on a daily basis.

Recycle your items wherever possible. Separate your items depending on those that can actually be recycled, and those that may not. Before you throw something in the bin as trash, make sure to think about whether the item can be recycled in its entirety or perhaps a part of it can.

Reuse your items as much as possible before you end up replacing them. Only buy essential necessities and choose your products wisely (preferably those with less packaging). Always look for items in your surrounding that can be reused.

Those three ways are very crucial when it comes to achieving sustainable living. At the same time, it helps humans reduce the amount of waste released into the environment.

hope this helps!! p.s. i really need brainliest :)

Identify the type of neuronal cell that detects bright light and provides high-resolution color vision.
alina1380 [7]

Answer:

The correct option is b. cones.

Explanation:

Cones and rods are specialized cells, called photoreceptor cells, that are found in the retina and are responsible for our vision.

Cones, allow to the human eye to have a visual acuity (ability of the eye to resolve, transmit sharp images and perceive small details in an object) and provide sensitivity to the color, are more concentrated in the central yellow spot known as the macula.

There are three different types of cones in color reception: "L cones" (sensitive to long wavelength, which is red), "M cones" (sensitive to medium wavelength, which is green) and "S cones" (sensitive to short wavelength, which is blue). Since color perception depends on the activation of these three types of nerve cells, it follows that the visible color can be determined based on three numbers called triestimulus values.

The rods are necessary for the perception of light and darkness and to adapt to night vision, because they are very sensitive to low intensity light. On the contrary, they become completely blind to bright light and, therefore, lack importance with regard to daytime vision or visual acuity.
