In the course of recent years, 60 percent of all biological community administrations have declined as an immediate consequence of the change of area to the creation of nourishments, powers and strands. This ought to shock no one, say seven of the world's driving ecological researchers, who met to all things considered study the pitfalls of using markets to prompt individuals to assess the natural expenses of their conduct and arrangements. We are getting what we pay for.
Amino acids are used in the production of proteins!
Answer: True
Explanation:
<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.
To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).
Answer:
They are capable of regenerating body parts
.
Explanation:
Ambystoma mexicanum or commonly "axolotl" is an amphibian that live in the Mexican basin and currently is in danger due to the destruction of its natural habitat. This species is used in scientific research because the axolotl is capable of regenerating lost parts of their bodies.
