Answer:
B
Explanation:
Because Molecules of carbon dioxide (CO2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO2 absorbing an incoming infrared photon (yellow arrows). ... This ability to absorb and re-emit infrared energy is what makes CO2 an effective heat-trapping greenhouse gas. And it will lead to green house effect...
Answer:
Endospores.
Explanation:
Microorganisms usually adapt to changes in their environment. One example of an extreme survival strategy employed by certain low G+C Gram-positive bacteria, generally of the Firmicute family, is the formation of endospores. They have a very peculiar structure that helps with this survival feature: an outer proteinaceous coat surrounding the spore provides much of the chemical and enzymatic resistance. Beneath the coat there is a very thick layer of specialized peptidoglycan called the cortex, which aids in resistance to high temperature. They are resistant to desiccation, lysozyme, ultraviolet and gamma radiation, chemical disinfectants, starvation AND temperature. So, in this experiment, it is probable that the boiled broth contained endospores, which survived this heating and then reactivated its metabolism.
Answer:
0.91, 0.55
Explanation:
When the partial pressure of O2 in venous blood is 30 Torr, the saturation of myoglobin with O2 is 0.91 while the saturation of hemoglobin with O2 is 0.55
Answer:
SIMPLE DIFFUSION transport
Explanation:
According to this question, John could smell the fragrance of his newly bought bottle of cologne all the way up the hall before he can even get into his bedroom, where he usually keeps it. However, he realizes when he got to his bedroom that he left the bottle of cologne uncovered.
The fragrance of the cologne that spreads from the bedroom all through the hall is as a result of SIMPLE DIFFUSION, a form of PASSIVE TRANSPORT. Diffusion is a form of passive transport in which molecules/fluids move from a region of high concentration to a region of low concentration until it is evenly spread. This is the case with John's cologne, which spread from the bedroom where the concentration is high to the hall, where it is low.
