The main difference between a sheep heart and a frog heart is that sheep have a
four-chambered heart and frog
three-chambered heart.
<span>The heart of an amphibian, such as a frog, has three chambers, one ventricle and two atria. Blood from the ventricle travels to the lungs and skin where respiration occurs and where the blood becomes oxygenated. From the ventricle, blood also travels to the rest of the body where it becomes deoxygenated. In the ventricle, deoxygenated and oxygenated blood are mixed before being pumped out of the heart. </span>
<span>On the other hand, mammals (including sheep) have two atria and two completely divided ventricles. The left side of the heart pumps and receives only oxygenated blood while the right side of the heart pumps and receives only deoxygenated blood, meaning that their systemic and pulmonary systems are separated. The separation of these two systems enables mammals to
deliver more oxygen to their tissues (because there is no mixing of oxygenated and deoxygenated blood)<span>. Thus, mammals' heart is more efficient.</span></span>
Answer:
1- DNA replication: two identical DNA strands
2- Transcription: mRNA
3-Translation: proteins
4- Mitosis: two identical diploid somatic cells
5- Meiosis: four different haploid gamete cells
Explanation:
1- DNA replication: through the process of semiconservative DNA replication two identical DNA strands are created
2- Transcription: the process by which DNA becomes mRNA
3-Translation: the process by which mRNA becomes proteins
4- Mitosis: a parent cell will split into two identical diploid somatic cells, this process is used to replace old cells
5- Meiosis: a parent cell will split into four different haploid gamete cells, this process is used to create ovary/testes cells
Answer:
and you just answer cuz you want points.
