Answer: A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.
Explanation:
Bottom-up mechanism is a process in which a body perceives an incoming stimulus and certain physiological changes occurs in the body working in the direction of upwards that is the signals are transferred to the brain so that the brain could interpret the stimulus. This mechanism suggests the fact that our perceptual experience is based upon the sensory stimuli.

In certain organisms, like humans, there are two morphologically distinct types of gametes: (1) the male gamete (i.e. sperm cell) and (2) the female gamete (i.e. ovum). The male gamete is smaller in size and motile whereas the female gamete is several times bigger and non-motile. The haploid condition of the two gametes is essential so that at fertilization during sexual reproduction the integrity of the chromosomal number is maintained throughout generations.
Hope this helps.
Answer:
Template strand = complementary strand
GCA AG = CGT TC
TTA CG = AAT GC
GAT AC = CTA TG
CGG AT = GCC TA
DNA strand = mRNA strand
CGA TT = GCU AA
GCT TA = CGA AU
GCA TC = CGU AG
TTC AT = AAG UA
It is more important for DNA replication to be exact than transcription or translation because any error that occurs during DNA replication if not repaired will become permanent and will be transferred to the next generation.
Explanation: In DNA base pairing, G pairs with C and T pairs with A. But in RNA base pairing, G pairs with C and U pairs with A. DNA contains four bases G, C, T and A while RNA contains four bases G, C, A and U.

Answer:
Option B, They generally focus on one target insect to ensure that the target insect population remains low.
Explanation:
Biological pest control methodologies are focused towards a specific species of pest and do not harm the non-targeted species. These methods are environment friendly and do not produce any harmful residues. Also they do not develop any kind of resistance in species due to which the same bio pesticide can be used again and again. Since these methods have high specificity, they may require usage of two or more bio pesticides all together.
Hence, option B is correct
