Oh I know this, It narrows down its characteristics here is an example:
The first step in the key will be organized the following way:
1. a. wings covered by an exoskeleton
b. wings not covered by an exoskeleton
Next, the statements need to lead the observer to the next step to narrow the identification further:
1. a. wings covered by an exoskeleton go to step 2
b. wings not covered by an exoskeleton .go to step 3
Step 2 needs to consist of a pair of statements that will allow for the identification of the ladybug and the grasshopper:
2. a. body has a round shape .ladybug
b<span>. body has an elongated shape .grasshopper</span>
#1 PROBABILITY is the likelihood that a given event will occur.
I'm not sure on #2, Sorry
Answer:
c
Explanation:
The very primitive and early microorganisms on the earth's surface were protobionts. Protobionts are cell-like microscopic structures, and they are made up of organic and inorganic molecules present in a lipid bilayer membrane. The layers of the lipid membranes were folded into bilayers and transformed into a bubble shape when placed in water. These membranes were selectively permeable and also observed shrinkage and swelling in osmotic conditions. Protobionts also possess the characteristics of reproduction.
