1. a) predation is when one organism is harmed and the other is benefited. An example of this is when a predator eats/hunts its prey - like a lion eating a lamb
b) commensalism is when one organism benefits from the other and the second organism is not affected. An example of this are the barnicles on a whale
c) symbiosis is the long-term interaction between two different biological organisms
d) parasitism is when one organism is harmed while the other is benefited

Answer:
Sensory neurons
Explanation:
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain.
Answer:
RrYy is the genotype that is heterozygous for both seed shape and seed color. The traits here we are discussing are pea plant's seed color and shape.
Explanation:
A dihybrid cross is a cross in which two traits are simultaneously being studied. Here there are two traits under consideration that are seed shape and seed color. The seed shape can be round or wrinkled and seed color can be yellow or green. The round seed allele is dominant over yellow seed allele and the yellow color allele is dominant over green color allele.
As homozygous indicate both alleles of a gene are same in an individual and heterozygous condition indicates that both alleles of a gene in an organism are different.
Therefore the genotype of homozygous pea plants for seed color and seed shape can be RRYY or rryy respectively and genotype of heterozygous genotype will be RrYy respectively.
Hope it helps!
