Sand needed the least amount of water. The soil drained faster because of the large particles that have more space in between.

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>
Answer:
Endosymbiosis of an oxygen-using scavenger bacterium in a larger host cell−the endosymbiont evolved into lysosomes.
Explanation:
The evolution of eukaryotic cells in all probability included: endosymbiosis of an oxygen-utilizing bacterium in a bigger host cell−the endosymbiont developed into mitochondria. development of an endomembrane framework and consequent advancement of mitochondria from a segment of the Golgi. endosymbiosis of an oxygen-utilizing photosynthetic bacterium in a bigger host cell−the endosymbiont advanced into mitochondria. endosymbiosis of an oxygen-utilizing scrounger bacterium in a bigger host cell−the endosymbiont developed into lysosomes.
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
