Physical activity causes an increase in your heart rate. Your body have to change the way it behaves so you don’t get ill or sick or pass out during physical exertion
Answer: The answer is D - Intramembrane space in mitochondria; high
Explanation:
Mitochondria is an organelle in the cell, it is known as the power House of the cell because of its role in the storage and production of energy. During electron transport chain the proton pumps generate a proton gradient which is stored in form of energy.
During proton pumping and electron transfer the electrons are passed down the chain from the matrix to the inter membrane of the mitochondria. The electrons move from higher concentration of level to lower energy level. Some of these are used to pump Hydrogen ions (H+), moving them out of the matrix into the inter membrane space.
The Intramembrane space of the mitochondria therefore has a a high concentration of Hydrogen ions (H+).
I hope this helps.
This is because the GP120 protein
of the HIV virus that forms the ‘knob’ is
essential for the infection of CD4 cells
of the immune system by the virus. The glycoprotein is, therefore, a good
target for vaccines especially since the
molecule is highly conserved because most mutations in the region could be highly deleterious to the virus.

Answer: The death of frogs would send a ripple through the ecosystem. The number of animals that eat the frogs will die off, then the animals that eat them will go hungry, and their populations will be devastated as well. This would just keep going up the food chain
Explanation:
Invasive bullfrogs upset the balance of predator-prey interactions and competition for food and shelter, but they also may be worsening another ecological disaster in the amphibian world. ... The invasive American Bullfrog can act as a vector, harboring this fungus, with no ill effects, and spread it to other amphibians
hopefully this helps :)
