Answer:
Explanation:
the two populations will become different species over time due to accumulated mutations occuring in both populations
The correct answer is A.The climate is changing rapidly but it will be too expensive to fix.
Explanation:
Climate change involves important long-term changes in climate patterns as well as other features on land and bodies of water. This phenomenon has occurred naturally during the history of Earth; however, nowadays climate change has accelerated due to human activities that produce global warming and therefore the increase in temperatures and changes in climate.
Despite this, some deny climate change, which is known as climate change denial; this includes stating climate change does not exist, it is an exaggeration or a hoax, or considering it is the result of natural cycles. According to this, the only statement that is not based on climate change denial is "The climate is changing rapidly but it will be too expensive to fix" because in this statement the speaker recognizes climate change is real and considers it is a serious issue that might be difficult to solve.
Answer: The space between the sun and Earth contains no matter.
Explanation:
MODES OF HEAT TRANSFER
1. Conduction: This type of heat transfer happens when there is direct contact between the two objects.
2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas).
3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
Thus convection can not take place between earth and sun as there is no liquid or gas present for movement of heat. The heat is transferred from sun to earth by radiation as it occurs through space.
Answer:
95%.
Explanation:
Oxygen-hemoglobin dissociation curve:
Oxygen-hemoglobin dissociation curve is basically a sigmoid curve which relates between the saturation of oxygen (SO2) and partial pressure of oxygen in blood (PO2). It shows the affinity of oxygen with hemoglobin at different temperature and other factors. In the oxygen-hemoglobin dissociation curve; saturated oxygen is ploted on verticle axis and partial pressure of oxygen in mmHg on the horizontal axis.
Here in the above scenario at the high altitude oxygen is less and at 80 mmHg, Hb would be 95% saturated.
