Answer: A parasitic bacteria contaminated her food.

Explanation:

Bacteria are simple prokaryotic single celled organisms which is capable of developing parasitic, mutualistic, commensalistic and predatorial relationships with other organisms.

According to the given situation, A parasitic bacteria contaminated her food. is the correct option this is because of the fact that bacteria are airborne organisms which are capable of colonizing the food we eat. When the food contaminated by bacteria is eaten by the host, it can infect as a parasite which means the bacteria will derive nourishment from the host body and disturbing the health of the host organisms.

The graph represents velocity vs. time for Carla. A graph with horizontal axis time (seconds) and vertical axis velocity (meters
kherson [118]

Answer:

The statement that best describes the graph is Carla slowed down in the beginning of her trip, stopped, and then sped up.

Explanation:

Data:

Horizontal axis = time.

Vertical axis = velocity (m/s).

A line runs in straight segments

  • <em>from 0 seconds 15 m/s.</em>
  • <em>to 1 seconds 13 m/s.</em>
  • <em>to 2 seconds 10 m/s.</em>
  • <em>to 3 seconds 4 m/s.</em>
  • <em>to 4 seconds 0 m/s.</em>
  • <em>to 6 seconds 4 m/s.</em>

According to the data present in the graph, it can be seen that Carla starts with a speed in her career, which decreases over time. After four seconds she stops, remains stopped for one second and starts running again, with an initial speed of 4 m/s.

<em>In conclusion, the graph show Carla -who is moving- slows down until she stops, and then starts the race again.</em>

9. Look closely at the illustration above. a. What process is occurring? b. What is being made? c. How can you tell?
mars1129 [50]
The answers are:

A. DNA replication in the nucleus of a cell
B. From one helix of DNA in a replication process, we get two: The DNA is a double helix and it consists of two strands of specifically connected amino-acids. When the time for replication comes, a set of enzymes unwind the two strands and leave them as a base for additional two strands attaching to them - the green line is an example of that. The free nucleotides - adenine, guanine, thymine and cytosine are left open and the enzyme called DNA-polymerase helps to produce a new strand on the template of the old parental one (one of the blue ones in the picture) 
C. By the location on the smaller picture - replication takes place in the nucleus. And the most important hint are the letters A - adenine, G - guanine, T- thymine, and C-cytosine. A connects with T, and G connects with C.
