1. How does the cell membrane allow animals to move without rupturing the cells in the body?
oksian1 [2.3K]

.

Explanation:

1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.

2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.

3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .

4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .

5) UMASS STEM-ED From Bubbles to Cell Membranes Workshop. Bubble ... dynamic nature which can't be properly appreciated in a static textbook. ... the small thread through one of the straws.

6) example of passive transport and active transport across a cell membrane so, cell membranes are semipermeable meaning they have control over what molecules can or cannot pass through. Some molecules can just drift Inn.

MakcuM [25]

Explanation:

Echolocation is one of the methods of orientation mainly used by the microchiropteran or insectivorous bats. While flying, these bats emit high frequency ultrasound. These sound pulses hit obstacles like rocks, trees, walls etc. and their echoes are heard by bats.

tankabanditka [31]

The right answer is A.

Storing and transmitting the genetic information is the role of the DNA.

Proteins are biological macromolecules found in all living cells. They are formed of one or more polypeptide chains. Each of these chains consists of the sequence of amino acid residues linked together by peptide bonds. They can have multiple roles depending on their structure and composition

1- Maintenance of oncotic pressure

2- Buffer role

3- Transport function

4- Enzymes and Coenzymes

5- Role in coagulation and fibrinolysis

6- Role in immunity and allergy

7- Role in inflammation

8- Hormonal role
