2. Analogous structures
3. Comparative anatomy
4. Fossils
5. vestigial
6. homologous structures
7. Comparative embryology
8. structure
9. Scientists
Explanation:
1. Human and apes are evolutionarily closely related based on the analysis of their DNA sequences.
2. Wings of bats and birds serve the same function and are analogous structure.
3. Comparative anatomy is the study of the similarities and differences in structures in similar species.
4. Fossils demonstrate that during the evolution of the whale, the whale moved from land to the sea.
5. The human tailbone and appendix are vestigial organs.
6. The homologous structures are structures that are similar in related organisms because they were inherited from the common ancestor.
7. Comparative embryology is the study of similarities and differences in the embryo of different species.
8. The forelimb of all the mammals has basic bone structure.
9. Scientists who find and study fossils are called paleontologists.
Why temperature affects heart rate in ectothermic organisms? If the temperature is within the optimal range for enzyme activity more ATP will be produced and the heart will beat faster due to increased metabolic activity and energy availability.
Answer:
A) Faster blood flow: A faster blood flow means the heart pumps blood with more power. Pumping blood to fast for too long can damage the heart muscle and interfere with its normal electrical signals, which can result in a dangerous heart rhythm disorder.
B) Infection: infection is caused by invasion of the body by external microorganisms. Disease can arise if the host's protective immune mechanisms are compromised and the organism inflicts damage on the host.
C) vomiting: This is an involuntary, forced expulsion of stomach contents usually through the mouth or nose. Body's reaction can be aspiration, electrolyte and water loss, damage to the enamel of the teeth, tear of the esophageal mucosa etc.
D) High blood pressure: This is due to the heart pumping blood at high pressure putting a strain on the walls of the blood vessels. In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs.
Biology is the study of life so a Biologist would study biology: the study of life and living things.
