Answer:
yes
Explanation:
Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.
PLEASE HELP!!!!!!!!!!
Answer:
They release oxygen into the atmosphere.
Explanation:
Cyanobacteria are photosynthetic bacteria that harness the energy from the sun to make food. Using light energy that they trap with photosynthetic pigments, they convert carbon dioxide and water into sugar and oxygen. Therefore, they release oxygen into the atmosphere.
This is clear from the graph, as oxygen levels rise sharply shortly after the first oxygen producing cyanobacteria appear.

List two important scientific changes that affected the human growth rate.
Technology is important scientific changes that affected the human growth rate. It is used to improve technology for harvesting food. Coupled with technology the have also increase good sanitation and that has accelerated growth rate.
What is scientific knowledge?Empirical evidence underpins scientific knowledge. Finds accurate instances of data that can be used as evidence.Scientific knowledge changes over time because new experiments are conducted and new data is introduced best describes the history of scientific knowledge.
For example, much of the information about the seafloor is gathered through indirect methods. Instead, scientists time how long sound waves take to reflect off the ocean floor.
Because all scientific theories require experimental and observational confirmation, all scientific knowledge is vulnerable to change in principle as new data becomes available. Science knowledge's accepted viewpoints might shift throughout time.
Therefore, Technology is important scientific changes that affected the human growth rate.

Cactus was introduced to Australia and quickly spread over millions of acres of land. A parasitic moth which preyed on and killed the cactus was then introduced to slow the spread.
Which of the following graph best describes the changes in population growth of the cactus? (bafora and aftar introduction of the moth)
A. 1
B. 2
C. 4
D. 5
Answer:
D)4
Explanation:
The graph has to have exponential growth in the beginning, ruling out 3. Then, the paragraph states the moth was introduced to slow the spread. 1 is all over the place and inconsistent, and 2 is basically taking the cactus away. 4 is leveling out the exponential growth, so it's 4
The graph that best describes the changes in population growth of the cactus before and after the introduction of the moth is four.
What do you mean by Population growth?Population growth may be defined as the increase in the number of individuals in a population over a certain period of time in a given area.
Graph four describes the phenomena of exponential growth, which means that before the introduction of the moth the population of cactus rose rapidly. But as the moth was introduced, the population of cactus slows down not completely decreases.
Therefore, the graph that best describes the changes in population growth of the cactus before and after the introduction of the moth is four.

Answer: You would expect 25 Kcal of energy stored in trophic level 4.
Explanation:
Energy flow in the ecosystem follows 10% law according to which 10% of the energy in the lower trophic level is transferred to the next trophic level.
In this example grass belongs to the first trophic level, producers.
Energy of grass=25000Kcal
Energy transferred to trophic level 2=10% of 25000=2500
10% of the energy in trophic level 2 is transferred to trophic level 3.
Hence energy at trophic level 3=10% of 2500=250Kcal
Energy transferred to trophic level 4=10% of energy in trophic level 3
=10% of 250=25Kcal
Energy to be stored in trophic level 4=25Kcal
Answer:
There will be 25 Kcal
Explanation:
The 5th - .01% out of 25000 is 2.5
The 4th - .1% out of 25000 is 25
The 3rd - 1% out of 25000 is 250
The 2nd - 10% out of 25000 is 2,500
The 1st - 100% out of 25000 is 25,000

Where is the energy to make ATP
coming from?
Answer:
The energy for the synthesis of ATP comes from the breakdown of foods and phosphocreatine (PC). Phosphocreatine is also known as creatine phosphate and like existing ATP; it is stored inside muscle cells. Because it is stored in muscle cells phosphocreatine is readily available to produce ATP quickly.
Answer: glucose
Explanation:the energy to make ATP comes from glucose. Cells convert glucose to ATP in a process called cellular respiration. Cellular respiration: process of turning glucose into energy In the form of ATP.
