The right option is inducible
defense
Inducible defense is a defense mechanism
activated by plants against herbivore attacks.This mechanism is activated through
a prior encounter with a consumer that confer some level of resistance to
subsequent attacks. For the question given above, production of chemical defenses by an algae after it has been grazed upon by a
herbivore is an example of inducible
defense.
The answer is b. ectomorphs because they have bodies that are tall and thin <span />
Cell wall constituents polysaccharides nucleic acids
Answer:
Option C, 3′-GTCAAGCCT-5′
Explanation:
The template used for replication synthesizes amino acids with
a) reverse head and tail ends - which means the 5' end will pair up up with the 3' end of the amino acid synthesized by the given template like wise 3' will pair up up with the 5' end of the synthesized amino acid.
b) The pairing of template occurs as per the rule of base pair in which
adenine (A) pair up with thymine (T) and guanine (G) pair up with cytosine(C).
Thus given template 5'-CAGTTCGGA-3' will
synthesise 3′-GTCAAGCCT-5′
Hence, option C is correct
Answer:
The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.
There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.
For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.
Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.
