It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation

Answer:
The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen ... It sends out an electrical signal to start the contracting (pumping) of the heart muscle.

Answer: They do affect the health of an ecosystem.
Explanation: In an ecosystem there are many things that are biotic and abiotic. For an example: water is abiotic and plants/animals are all biotic, the water is not living but it keeps the ecosystem alive by quenching the thirst of the plants growing from the ground and the animals roaming around on the land. Dead animals and plants are not abiotic and they are now providing food for fungi and bacteria. Without the abiotic factors, it would be difficult for the biotic to survive.
