Answer:
A
Explanation:
"A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe's age of 13.8 billion years. (This long lifetime is one reason red dwarfs are considered to be good sources for planets hosting life, because they are stable for such a long time.)"
Answer:
The correct answer - The Gas giants are much much larger in size.
Explanation:
There are two distinct types of planets that are four rocky planets and four gas giants plants. Mercury, Venus, Earth, and Mars are four rocky planets, and Neptune, Uranus, Saturn, and Jupiter are four gas giants.
The Gas giants plants are much much larger in size in comparison to the rocky planets. It is because rocky planets have relatively low gravity than gas giants and were not able to attract large amounts of gas to their atmospheres.
Thus, the correct answer - The Gas giants are much much larger in size.

disorder is a communication disorder that involves discontinuous flow and
timing of speech. It is mostly seen in children who are learning to speak. Physical
tension, negative reactions, and avoiding of speaking situations work together
with this disorder. Individuals with this disorder display repetition of words,
sound extensions and long pauses when speaking. For the question given above, a
12-year-old student who says "i-i-i-i want i-i-i-ice c-c-c-cream" is
exhibiting fluency disorder.</span>
Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
