Answer:
Evolution, mutation, and adaptation
Explanation:
Since different organisms adapt to different environments and receive different mutations, they adapt differently and slowly change. That is why there are different species of birds, just look at the galapagos islands, there are thousands of species of finches that changed to survive on each island. The same could be said for every organism since the early organisms that we evolved from were widespread, some evolved differently than others, leading to different fish, different lizards, different early mammals, and so on. That is why humans look different than dogs or cats, we evolved best to our environment so we could survive.
Answer:
Circulatory system
Explanation:
From the right atrium through the tricuspid valve to the right ventricle through the pulmonary sigmoid valve to the pulmonary trunk to the right and left lungs to the capillary beds of the pulmonary veins to the left atrium to the left ventricle of the heart through the mitral valve, to the aorta through the aortic semilunar valve, to the whole body, to the systemic arteries, to the capillaries of the body tissues, to the systemic veins, to the superior cava vein and inferior cava vein, which enter the right atrium of the heart.
Answer:
When a substance changes into a new substance
Answer:
d. incomplete dominance
Explanation:
When none of the alleles of a particular locus completely masks the expression of the other allele of the same gene, it is called incomplete dominance. If the allele B gives "blue" phenotype and allele b gives white phenotype, a cross between blue (BB) and white (bb) parents would produce all the progeny with genotype Bb. Since the allele B does not completely prevent the expression of allele b in the heterozygous condition, the phenotype of the F1 hybrids would be "light blue". Therefore, it is an example of incomplete dominance.
blue (BB) x blue (BB) = all blue (BB)
white (bb) x white (bb)= all white (bb)
blue (BB) x white (bb)= all light blue (Bb)
