Answer:
390W are used to just power the leaf blower.
Explanation:
Therefor less than half its power is being used for it to actually do its job.
Hope that helps! Good luck!
Carrier proteins are involved in passive transport, moving solute molecules form one side of the membrane to the other. Option (A) is not true. <em>They increase the </em><em>speed of transport</em><em> across the membrane. </em>
<h3>Facilitated diffusion </h3><h3 />
- It is the transport of hydrophilic molecules that can not freely cross the membrane.
- Channel protein and many carrier proteins are in charge of this transport.
- When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one.
- When ions need to cross the membrane, the process depends on an electrochemical gradient
<h3>Carrier molecules</h3><h3> </h3>
- Carrier proteins move molecules from one side of the membrane to the other side.
- They do not need energy. They move solutes according to the electrochemical gradient.
- The carrier proteins have specific binding sites recognized by the transported molecules.
- When the proteins and the solutes get together, the carrier proteins suffer a temporal change in their structure.
- These changes allow the solute passage to the other side of the membrane.
<h3>
</h3>
Options,
(A) They increase the speed of transport across the membrane. FALSE
(B) They concentrate solute molecules on one side of the membrane TRUE
(C) They have specific binding sites for the molecules they transport. TRUE
(D) They undergo conformational changes upon binding the solutes. TRUE
The incorrect option about carrier proteins is A. <em>Carrier proteins </em><em>Do Not increase</em><em> the </em><em>speed</em><em> of </em><em>transport</em><em>. They just make it possible. </em>

Answer: ribosome
Explanation:
rhe mRNA (messenger RNA) takes the transcribed RNA strand to ribosomes in the in the cytoplasm. Here, tRNA will attach to codons using anticodons. The tRNA will also bring amino acids that will make a polypeptide chain. This makes proteins.
Some ncds, that includes Parkinson's disease usually begins with impaired motor control. Parkinson's disease is a neurodegenerative disorder, that then leads to progressive deterioration of the motor function because of the loss of dopamine in brain cells. The cause is unknown yet mostly because of geneti or environmental factor.
Answer: When you study environmental science, you commit to learning of accomplish important tasks for our Earth and our human population.
Explanation: Hope this helps! :)
