Answer:
True
Explanation:
In Retrovirus such as HIV, when the virus enters the host's cell it releases enzyme reverse Transcriptase which generates a complementary DNA(cDNA) by the process called Reverse transcription.
By this process the positive single stranded RNA genome is liberated into a cDNA molecule.
Since the process of reverse transcription is prone to errors, it can cause mutation that lead to drug resistance or enable the virus evade the body's immune system.
B. facilitated diffusion
C. passive transport
D. photosynthesis
What’s the answer?
B. the particular choices made in the adaptation
C. how much more enjoyable the adaptation is than the original
D. the effects of the choices made in the adaptation
E. why the choices made in the adaptation are effective
Factors which are being applied when evaluating whether the adaptation is success include;
1. Why the choices which are made in the adaptations are effective.
2. The effects of the choices made in the adaptation.
3. The particular choices made in the adaptation.
Adaptation is termed as dynamic evolutionary process which fits organisms to their environment which enhance evolutionary fitness.
Organisms face succession of environmental challenges as they grow and they show adaptive plasticity when traits develop as they show adaptive plasticity when traits develop.
b. Aces the plastic bag was permeable to iodine.
c. The iodine moved into the plastic bag.
d. The cornstarch moved into the beaker.
e. The plastic bag was selectively permeable.
The solution in the dialysis tubing bag turning dark purple indicates that the iodine has moved into the bag and reacted with the cornstarch. This means that options (b) and (c) are correct.
The dialysis tubing bag is selectively permeable, which means that it allows certain molecules to pass through while blocking others. In this case, the bag is permeable to iodine molecules, but not to larger molecules such as cornstarch. Therefore, option (e) is also correct. The cornstarch did not move into the beaker, as the bag is designed to keep its contents inside. Therefore, option (d) is incorrect. The fact that the solution in the bag turned purple indicates that the bag was permeable to cornstarch, as it allowed the iodine to come into contact with the cornstarch and produce the purple color. Therefore, option (a) is also correct.
Because the solution in the bag turned purple as a result of the iodine's contact with the cornflour, it can be concluded that the bag was permeable to cornflour. This contact enabled the purple colour to be produced. As a result, choice (a) is also accurate.

Answer: The optic lobe gives the sense of vision. The large size of the optic lobe of a frog brain suggests that the major part of processing in the brain of frogs is associated with vision.
In other words, frogs require to process large amount of visual information ( sent by retina via optic nerve) very quickly and effectively. Large and bulging eyes are very sensitive to movements and have excellent night vision. They can visualize things in front, to their sides, partially behind.
Thus, large optic lobe of a frog brain provides great significance to them.
