For the first question, i think the correct answer is A. Normal cells undergo apoptosis while cancer cells don't. For the second question, The answer is option B.<span> </span><span>Cell division has two checkpoints namely, G1
checkpoint and spindle assembly checkpoint. The checkpoint which determines if
division has properly occurred is the G1 checkpoint. At this point, is a damage
in the DNA is detected or the has not reach the optimum size, the cell is
stopped in G1 and is not allowed to proceed to further process.</span>
The answer to this question would be: False
The symbiotic between plant and fungus is called lichen. In this case, the Mycorrhizae having a mutualism symbiotic with algae as they are giving benefit to each other. The Mycorrhizae will give water and inorganic compound and the algae will give food. The answer is false because the algae are not parasitic to the fungi.
C) The core contains equal amounts of hydrogen and helium
Answer:
The DNA is copied by B: The sense strand of DNA is used as a template to create both strands of the new double helix.
Explanation:
Ok, the DNA is "copied" in the tanscription process. The transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Also, the DNA safely stores genetic material.
During the process of transcription a single strand of RNA is synthesized using a double stranded DNA molecule as a template. The two strands of the DNA molecule are separated from one another, exposing the nitrogenous bases. Only one strand is actively used as a template in the transcription process, this is known as the sense strand, or template strand. The complementary DNA strand, the one that is not used, is called the nonsense or antisense strand.
