Answer:
Neurotransmitters
Explanation:
Neurotransmitters are the chemicals present in the body used for the propagation of action potential. These neurotransmitters are also known as the body chemical messengers.
Neurotransmitters are stored in the neural cells. These chemicals are generally released when the cell is stimulated by the specific signal. The effect of neurotransmitter may be excitatory or inhibitory.
Thus, the answer is option (4).
Answer: Biodiversity loss
Explanation:
The biodiversity can be defined as the variety of life forms on earth or any other region. The forests are rich sources of biodiversity. The hunting, poaching, animal trafficking, and other ill-legal related human activities are like to reduce the species richness in forests. As many species are dependent upon other species for food, mate and other requirements for completing the life cycle thus the well-being of the forests will get deteriorated by the loss of biodiversity.
D I think because the trees block out all the sun
Answer:
Frequency of dominant allele is 0.9029
Explanation:
Total number of organisms = 12,845
Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.
Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249
Frequency of recessive allele (q) = 1249/12845 = 0.0971
Frequency of dominant allele (p) = 1- q = 1- 0.0971 = 0.9029
