Enceladus, one of Saturn's moons of only
about 314 miles in diameter hides in its entrails an ocean of liquid water that
is rich in organic molecules, making it one of the places where it is most
likely to find some form of extraterrestrial life.
Europa is a strange
shaped moon of Jupiter with a large number of intersecting lines. Models
from the interior of Europe show that under a thin crust of 5 km (3 miles) of
water ice, Europa can have oceans with 50 km (30 miles) of depth or more. The
visible marks of Europa could be the result of a global expansion where the
crust could have been fractured, filled with water and frozen.
Answer:If we were to remove just one level of organization all the other levels would fall apart. It would then become very difficult to make any decisions without all the levels put together as one.
Explanation:
Answer:
The correct answer is case-control study.
Explanation:
In a case-control study, two groups of the population are used, in which one group is kept as control, and the other is known as the experimental group that encounters with a specific disease or an outcome. With the help of this study, one can expose the groups to various or single outcomes.
In the given case, a study is done in which an advertisement on a ban on smoking is encouraged by the non-smokers at the alcohol sale points but not by smokers, in the process a random digit dialing method was used. This random digit dialing method is an illustration of a case-control study, in which the survey of the individuals is done regarding the ban on smoking.

The genotype of the offsprings would be Cc, Cc, cc, cc i.e heterozygous cleft chin and no cleft chin. The phenotype of the offsprings could be 50% cleft chin and 50% without cleft chin.
there will be 50% chance of the child to have cleft chin.
Answer No 3:
A a
A Aa Aa
a Aa aa
There will be 25% chance for the offspring to have arched feet. As arched feet is a recessive trait, so for this trait to occur both the alleles of the gene should be recessive i.e aa.
Answer No 4:
B b
b Bb bb
b Bb bb
As blonde is a recessive trait, so both the alleles for this gene should be recessive for this trait to occur. Hence, according to the punnet square, there will be 50% chance for the offspring to be blonde.
Answer No 5:
F f
F FF Ff
f Ff ff
As normal vision is a resessive trait, hence both the alleles of the gene should be recessive for the trait to occur. According to the punnet square, there is 25% chance that the child will have normal vision.
