Answer:
C. Ivan gets him.
Explanation:
Richard Connell's "The Most Dangerous Game" is about Sanger Rainsford, a famous hunter who cared less about his prey. But then the tables turned and he became hunted instead of being the hunter, thereby presenting the theme of civilization and savagery, conscience, etc.
After Rainsford reached "Ship Trap Island", he discovered that there lived someone, Colonel Zaroff. But soon, he became aware of the <em>"game"</em> that the colonel likes to hunt. Refusing to be a part of the hunt, he was offered to be either the prey (which leaves him a choice of being free if he survives 3 days being hunted) or be killed anyway by Ivan, the Cossack.
Thus, the correct answer is option C.
Answer:
Carbondioxide gas, release oxygen and provide food.
Explanation:
Plant absorb carbondioxide gas, release oxygen and provide food to the animals are the was that plants impact the cycle. Plant absorb carbondioxide gas from the surrounding air in the presence of sunlight and absorb water from the soil. Both carbondioxide and water react with each other in leaves producing glucose and oxygen. Glucose is stored in different parts of plant body whereas some oxygen is used by the plant for respiration and the remaining is released in the atmosphere. The food produced in the plant can be eaten by the primary consumer for their growth and in that way the ecosystem moves in forward direction.
Answer:mouse cell line
Explanation:
The somatic cell hybridization experiment involves hybridization of human Gene to rodent gene
Answer:
a) true
Explanation:
It is absolutely right that in mammals dosage compensation occurs due to X-inactivation in females. It happens because in mammals like humans, females have XX and males have XY as allosomes. Because of the presence of two X chromosomes, each gene is present in 2 copies in females but in males only 1 copy is present as they have only one X chromosome. So in order to compensate for this kind of difference, one of the female X chromosomes undergoes inactivation and this phenomenon is known as dosage compensation.
The X chromosome undergoes inactivation because of its DNA modification and acts very different from other X chromosomes. Several methyl groups are added to the DNA of such X chromosome so as to inactivate it. In general such inactivated X chromosome is known as bar body which appears like a darkly stained structure.
Note: In other lower organisms like drosophila and C. elegans other mechanisms of dosage compensation exist.
In drosophila rather than inactivation of one chromosome in female, the transcription rate of one X chromosome of male is doubled so that it could produce as much transcripts as two X chromosomes of female are producing.
In C. elegans, both the X chromosomes are active but partially. The transcripts produced by two X chromosomes of female equalize the transcripts produced by one X chromosome of hermaphrodite counter part.
