NASA reignited our hopes of finding alien life when it announced the first direct evidence of liquid water on Mars. But before we start indulging in fantasies of space crabs and reptilian beings, we ought to remember that Mars is a frigid world with a thin atmosphere. And that raises an obvious question: What sorts of life forms could actually live there?
Any life on Mars today is almost certainly microbial, but beyond that, we can’t be sure of anything until we actually dig it up and study it. Still, we can make some educated guesses about the nature of Martian life, by taking a deep dive into some of the weirdest biology on planet
Answer:
That theory describes how the universe with the state of singularity..
Answer:
(E) bu cv+
Explanation:
Linkage is the phenomena in which two genes present on same chromosome have a tendency to get inherited together.
It is given that the two autosomal genes are linked and in repulsion. This means that the dominant allele of one gene is linked to the recessive allele of another gene and vice versa.
Hence, the parental type gametes will have bu cv+ and bu+ cv combination. Since in linkage parental gametes always appear in higher numbers than recombinant gametes, out of the given options bu cv+ set of genes will be present in most gametes produced by this cockroach.
Answer: Booster dose of vaccine is given to elicit a secondary immune response ( by means of re-exposure of pathogen in the booster dose) so that more number of long lived antibody producing plasma cells are produced in the body.
Due to this, a higher level of protection is created in the body.
Whenever the body encounters the disease causing agent, it can easily clear off the infection.
Thus, booster dose serves as an additional vaccine dose to boost the memory of the immune system against a particular disease.
Example of vaccine that require booster dose- HPV ( human pappiloma virus), Hepatits A, Hepatitis B, Polio.
The buoyant force is an upward force on an object submerged in a fluid. It is the resultant of the pressure force on the surface of the object. The buoyant force may be larger than the weight of the object causing it to accelerate upwards.
