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 : )

Answer:

Rain makes up part of earth's water cycle

Water evaporates from streams, lakes, and oceans, then condensation and precipitation occur in the form of rain.

Explanation:

I'm pretty sure this question is implying that the answers should be directly related to the water cycle. While some of the other sentences might have some truth to them, they are too vague to be considered fact, and they're not necessarily related to the process of the water cycle.

Which genes would a crop scientist most likely insert into a crop to protect it from droughts and insects?
Aleonysh [2.5K]
Commonly, genes from bacteria are inserted into a crop's chromosomes to produce pesticide substances to kill insects

For drought, I'm not fully sure, but Maize is a very drought resistant crop often introduced to communities which receive little rainfall. Maybe they take a gene from the maize crop and insert it into the chromosomes

What biomes receive less then 100 Cm of rain each year? Check all that apply
jeyben [28]

<u>Answer</u>:- <em>Option 3 </em>(desert), <em>Option 4</em> (tundra) and <em>Option 5</em> (grassland).

<u>Explanation</u>:-

The amount of rainfall varies in different biomes:-

1. Tropical rain forests - The annual rainfall in these forests falls in the range of <em>125 to 660 cm</em> which varies according to the seasons.

2. Temperate rain forest - The annual rainfall in these forests can range from <em>200 cm to 350 cm</em> depending on the region where they are found. The annual rainfall is higher in warmer regions .

3. Desert - As the name suggests, the desert areas do not get enough rainfall. The annual rainfall in a desert is less than <em>25 cm</em>.

4. Tundra - It is a biome which is found in relatively cooler climates and the amount of rainfall is very less these regions. The annual rainfall in tundra biomes is less than <em>20 cm</em>.

5. Grassland - in these biomes, the rainfall is higher than the tundra and desert but is not as high as the rain forests and thus, grass is the dominant vegetation. The annual rainfall ranges from <em>60-90 cm</em>.
