The obligate aerobes need oxygen for their survival, while the obligate anaerobes do not. The obligate aerobes are the species that attain the energy for the process of aerobic respiration with the help of oxygen as the ultimate electron acceptor for the electron transport chain.
On the other hand, obligate anaerobes are the species, which get poisoned by the usual levels of atmospheric oxygen, and thus, get killed in the existence of oxygen.
Answer:
Obligate aerobes require oxygen from the atmosphere for survival, while obligate anaerobes do not.

Answer:
Dr. Leland Hartwell utilized the baker’s yeast; Saccharomyces cerevisiae
Paul Nurse used a different type of yeast, Schizosaccharomyces pombe, as a model organism.
Explanation:
Dr. Leland Hartwell utilized the baker’s yeast; Saccharomyces cerevisiae, as a model system, to study the enzymes that are involved in the control of mitosis including deriving the checkpoints concepts etc. Paul Nurse used a different type of yeast, Schizosaccharomyces pombe, as a model organism.
2) Nucleus is absent in red blood cells

4) Inner membrane of mitochondria is folded
5) Vegetable vendors regularly sprinkle water on the vegetables in their baskets.
6)Endocytosis occurs only in animals
All species have the same number of chromosomes in the nuclei of their cells
2. Endotherms have higher energetic demands compared to ectotherms.
3. Endotherms spend more energy on internal temperature regulation compared to ectotherms.
4. Endothermy is more common among animal phyla than ectothermy.
5. At the cellular level, endotherms cells always produce more ATP and more heat.
Answer:
3. Endotherms spend more energy on internal temperature regulation compared to ectotherms.
Explanation:
Ectotherms, are considered as cold-blooded animals (reptiles and amphibians), and are organisms that don't have the ability to generate enough heat to keep themselves warm. Endotherms, in contrast, do possess the ability to generate their own body heat.
Endotherms also called warm blooded animals (mammals) have the ability to regulate their body temperature by themselves. If the endotherms are in a cold place their body increases the metabolism and generates more heat. This will compensate for the cold outside.
