Receptors within the highlighted area provide the sense of HEARING.
The highlighted section of the ear is the organ of Corti. The organ of corti is the sensory receptor inside the cochlea, which holds the hair cells, which are the nerve receptors for hearing.
Answer: option A, B and D
Explanation:
The telomeres found at the terminal ends of eukaryotic chromosomes are long repetitive sequences that protects the DNA from being identify as a damage molecule to encourage fusion with other chromosomes. Since replication does not extend down to these 3' ends, the cell recruits the telomerase enzyme which is a ribonucleoprotein that helps to add telomeric repeats using its own RNA component as template to extend this end. Thus if mutation like a large deletion occurs in the gene encoding for this enzyme, the telomerase would not be able to associate correctly with the telomere, the catalytic center also encoding for its RNA polymerase would be altered and the enzymes will not be able to synthesize new telomeric repeats sequences
A should be labeled as being Bryophytes. I hope this helps anyone who needs to know this.
Answer:
Both biotic and abiotic factors affect the survival and reproductive success rate of fishes in an ecosystem.
The number of predators that a particular type of fish will have will influence the survival and reproductive rate of that fish. An increased number of predators will mean that the fishes will not be able to survive in that ecosystem and will be eaten up.
The number of preys will also affect the survival rate of fishes in an environment. The lesser the number of preys, the more the competition for food among species.
Abiotic factors like the concentration of salts in water will also influence the survival and reproduction of fishes. If a fish is not adapted to live in saline water conditions, then accumulation of salts in the ecosystem might destroy the whole fish species in that ecosystem.
Human activities, like the throwing of wastes into the aquatic ecosystem, drainage of fertilizers in the aquatic system can also destroy the survival and reproduction rate of a particular kind of aquatic animal species.
