Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.
Each week, a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.
What is the independent variable in this experiment?

5. What type of energy is needed for active transport?
4. You are running a race and you speed up from 3 m/s to 5 m/s in 4 seconds.
a. What is your change in speed?
b. What is your acceleration?
The initial speed is 3 m/s and final speed is 5 m/s. Change in speed is 2 m/s.
What is speed?The initial speed is 3 m/s and final seed is 5 m/s. The change in speed is final speed minus initial speed.
The rate at which distance changes over time is known as average speed. The pace at which displacement changes over time is known as average velocity.
Change in speed= 5 m/s − 3 m/s
= 2 m/s.
Velocity = speed/ time
= 2/ 4
= 0.5 m/s
acceleration = velocity/ time
= 0.5/ 4
= 0.125 m/s2
Therefore, The initial speed is 3 m/s and final speed is 5 m/s. Change in speed is 2 m/s.

is Sedimentary rock. tilting, erosion or folding
Answer:
Tilting - Rock strata always form horizontally, so anything not horizontal has been acted upon. ... Folding - If the rocks are bent, they have been folded. Faulting - If there is a break and movement within the rocks, this is a fault.
Explanation:
Answer
I'd have to say it's Tilting.
Explanation:
This question needs to be more specific since the form of the rock can form differently which ultimately alters this answer to most likely folding, but I'd have to say my best answer would be tilting. Hope this works!

B) chromosomes divide
C) cytoplasm divides
D) cells grow rapidly
E) chromosomes replicate
Cells grow rapidly and hromosomes replicate are occurs during interphase.
What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Hi, so i was wondering How long does Mars have to travel around Earth to make it's complete rotation?
Answer:
24 hours and 37 minutes
Explanation:
At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.
Answer:
The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.
Trees, such as those in the deciduous forest, are very important to the environment. If the number of trees on earth continues to decrease significantly, what might be the result? (Site 1)
Answer:
more carbon dioxide would build up without the tress to recycle it and many animals would lose their habitats
Answer:
Animals will begin to migrate towards residential areas if the number of trees on the planet continues to decline, as their natural habitat would be destroyed. There are numerous plant species that can be used as a source of medicine for disease prevention and treatment. Trees provide a significant amount of oxygen to the environment. Some deciduous forest trees grow near rivers, preventing soil erosion by attaching dirt to the plant's roots. Cottonwood, mountain ash, and fruit trees are commercially important trees. If there is a considerable reduction in the quantity of trees, all of the above benefits of trees will be lost.

Which process is part of the carbon cycle?
A. Photosynthesis
B. Transpiration
C. Evaporation
D. Fixation
Hey there!
Photosynthesis is part of the carbon cycle.
Plants absorb carbon dioxide & sunlight in the middle of the photosynthesis process and create glucose (a type of sugar).
I hope this helps,
have a wonderful day. :)
Photosynthesis is part of the carbon cycle. Therefore option A is correct.
Photosynthesis is a vital process in the carbon cycle, which is the biogeochemical cycle that describes how carbon is exchanged and recycled between the atmosphere, living organisms, oceans, and the Earth's crust.
During photosynthesis, green plants, algae, and some bacteria convert carbon dioxide (CO2) from the atmosphere into organic compounds, such as glucose, using sunlight as an energy source.
This process removes CO2 from the atmosphere, reducing greenhouse gas levels and helping to regulate the Earth's climate.
It is an essential step in maintaining the balance of carbon in the biosphere and plays a significant role in sustaining life on our planet.
Therefore option A Photosynthesis is correct.
