It's hard to say which kind of liquid is the first one.. I think it's a virus (but it also kinda looks like water though!)

1. A = either water or a virus
B = Blood
C = Bacteria
D = Water/Virus and Bacteria

2.The mouse dies after being injected with substance B and D and lives after injected with substance A and C

3. I think that if you inject the mouse with a different blood type it will not survive, just like with humans the blood will clot which can cause veins to close.
And I think with the last one; if you have a virus or caught a bacterial infection you would create anti-bodies/white blood cells to defend the body and be resistant to them. But when you combine them the virus will take the bacteria as a "host" to make more virus cells and if you don't take antibiotica (like in the mouses case) eventually he would get really sick.

Hope these are the awnsers you are looking for : )

Describe animal interactions that affect populations in the tundra ecosystem. (Please help please... I have already had a mental
GenaCL600 [577]

Answer:

Herbivorous animals are unable to feed and end up migrating to other regions in search of food.

Explanation:

The tundra is a type of vegetation composed almost exclusively of mosses and lichens. This type of vegetation is found in regions with a polar climate. It is important to note that the tundra has a very fast vegetative cycle. That's because it freezes quickly and can be covered with ice all winter. This ends up modifying the lives of some animals that feed on this vegetation. These animals end up with unavailability of food and need to migrate to others in search of food.

What type of reaction do cells use to combine smaller monomers into larger functional polymers?
mr_godi [17]
The reaction that links monomers to make polymers is polymerization. This process is also referred to as dehydration synthesis.  Two monomers are binding to each other and form one polymer. Example: hydrogen (H) from one monomer binds with a hydroxyl group (OH) from the other monomer and forms the polymer : H+<span> + OH</span>-<span> = H</span>2O - the <span>water molecule. </span>
