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).

Cytokinesis is when the cytoplasm of the cell divides, and it occurs during telophase and after the division of the nucleus. Interphase, which is when the cell grows and copies its genetic material, precedes mitosis.
Mitochondria is the answer they are the power house
Answer:
The correct answer is C) AUG AAU CCA UUU UGA.
Explanation:
First important thing to notice is that RNA doesn't have Thymine, all thymines are changed for Uracils. Then, the correspondency is thymine-Adenine, Guanine-Cytosine (and viceversa) Adenine-Uracil. Lastly, the transcription process happens from 3' to 5', so the question asks for the final result to be read to the opposite direction. Therefore, the correct answer is C.
