Answer:
If temperature drops, it is negative feedback whereas if the temperature increases, it is positive feedback.
Explanation:
When the temperature drops from 98.30 °F, it means it is a negative feedback because its response is negative while if the temperature increases from 98.30 °F, it means it is a positive feedback because its response is positive. From 12 am to 3 am which represents negative feedback, temperature decreases whereas from 3 am to 6 am, the temperature increases which indicates positive feedback. From 6 am to 9 am, again the temperature drops and this fall represents negative feedback and so on.
Answer:
Through this experiment we study the process of photosynthesis.
• In the begining the leaf disks's tissue has oxygen, this allows them to float.
• Then, in the experiment we infiltrate the leaf disks with a solution that has bicarbonate, and as a result their density changes (it increases) and so the leaf disks sink.
• Once the disks are on the bottom and we direct the light to them the process of photosynthesis starts, being the bicarbonate the source of carbon for the process.
• As we know a product of the photosynthesis proces is oxygen, so when it is released into the leaf disks the overall density changes again and the disks rise.
So as we can see, in this experiment the purpose of the bicarbonate is being the source of carbon for the process of photosynthesis that occurs in the leaf disks.

<span>Certainly. Every organism has a variety of different characteristics. One person writing a key might choose to use different characteristics than another person would use.
For example: Here's a key for separating fish, snake, frog and mouse
1.
A. Has scales on its skin ... 2
B. Has no scales on its skin ... 3
2.
A. Breathes with gills - fish
B. Breathes with lungs - snake
3.
A. Has hair or fur - mouse
B. Has no hair or fur - frog
Here's a different key for the same four animals:
1.
A. Has four legs ... 2
B. Does not have 4 legs ... 3
2.
A. is warm-blooded - mouse
B. is cold-blooded - frog
3.
A. has fins - fish
B. has no fins - snake</span>
Answer:
An antelope trots through the grasslands at a velocity of 2 m/s. Suddenly, a lion begins to chase the antelope. If the antelope accelerates at a rate of 2 m/s2, what is the antelope's final velocity after 5 seconds?
10m/s
Explanation:
A= v/t
A= Acceleration
V= Velocity
T= Time
2=v/5
v=10m/s
