Missing Question:
The question was missing information. I have found the question online and attaching it here for convenience.
Answer:
Option D
Explanation:
- From the picture, we can see two types of bacteria (i.e. A and B), therefore it is not a pure culture.
- We can not predict whether any culture has been lost during incubation.
- A and B are different organisms.
Hence, the only correct option is D, which states:
"Identification of microbial types in the environmental sample could have been attempted without culturing anything."
Answer:
w=23,x=126,y=119
Step-by-step explanation:
w=23
3(23)-15=54
opposite angle = 54
360-(54+54)=252
252÷2=126
x=126
180-61=119
y=119

Step-by-step explanation:
1. 
- given
2. 
- definition of midpoint (the midpoint of the segment divides the segment into two congruent segments)
3. 
- corresponding angles theorem (corresponding angles theorem states: If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.)
4. 
- SAS (SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent).
