Answer:
The correct answer is - 3 hours 15 minutes.
Explanation:
Given:
Speed = 768 km/h
distance = 2496
Solution:
Converting speed in km/minutes:
768/60 = 12.8
Now by the formula,
Time = distance/speed
time = 2496/12.8
=195 minutes
converting in hour = 195/60
= 3 hour 15 minutes.

Why does blue light cause a negative photosynthesis rate? (If algae is grown under blue light, why is the rate of photosynthesis slower than other colors?)
Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn't fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.

WOULD THERE BE ANY BACTERIA
IN AN AQUARIUM?
A balanced
aquarium
contains certain animals as
well as some plants. How
many kinds of animals can
you make out in the
aquarium shown here ? Name
any two such animals.
.............
...............
Do you think there would be
some bacteria in it? If so, in
which part of the aquarium
would they be occurring in
abundance and what for?
.................
Answer: yes, many different kinds
Explanation: bacteria are everywhere and so will be found in aquaria. Aquarium health is dependent on bacteria. Fish excrete ammonia which is toxic. Bacteria such as Nitrosomonas and Nitrococcus convert ammonia to nitrite, and Nitrobacter converts nitrite to nitrate which is relatively harmless. Bacteria such as Pseudomonas stutzeri and Bacillus subtilis remove nitrate and organic waste. There are also bacteria in fish intestines, and other bacteria that can cause fish diseases or create undesirable conditions such as Pseudomonas fluorescens, Vibrio, Flexibacter or Aeromonas and anaerobes that reduce sulphates to hydrogen sulphide.
Chemical reactions can occur in the cells of living things.

In your own words, explain why the landscape of Florida has not changed over time like that of Colorado.
Answer:
The landscape of Florida has not changed over time like that of colorado because the rock structures of colorado are much older than that of florida. Colorado also experiences a lot of tectonic plate movement. This led to the colorado river flowing through it and through weathering and erosion the landscape changed. Florida is not affected by the same things so the landscapes change in different pace
The landscape of Florida has not changed over time like that of Colorado because Colorado is a frigid mountainous area while Florida has a humid subtropical climate.
What do you mean by Landscape?The landscape of an area may be defined as the representation or visible region of a defined area that is set up by artificial boundaries.
The region of Colorado experiences the movement of tectonic plates that changes the area of river flowing which leads to the activities like weathering and erosions.
While Florida experiences a hot and humid climate with stable conditions. Hence, the change in landscape is not rapidly seen in Florida.
Therefore, it is well described above.
