Photosynthesis
Explanation:
Tiny organisms known as cyanobacteria, or blue-green algae conducted photosynthesis using sunshine, water and carbon dioxide to produce carbohydrates and oxygen.
The graph below shows the number of radioactive atoms present in four radioactive materials at different time intervals. Graph showing the time in hours on x axis and the number of radioactive atoms present on y axis for four materials A, B, C, and D. Curve A is on the left of the graph with curve B on its right. Curve C is on the right of curve B and curve D is to the right of curve C. The slope of curve A is the greatest, the slope of curve B is lesser than the slope of curve A but greater than the slopes of curve C and curve D. The slope of curve C is lesser than the slopes of curve A and curve B, but greater than the slope of curve D. The slope of curve D is the least.

Three quarters of Earth's surface is ocean. The aquatic communities found in the ocean are called marine ecosystems
appose the amount of sunlight in a marine ecosystem is drastically reduced Identity two different effects this change in sunlight will have on the ecosystem and explain how each impacts the aquatic communities. Tyy
Answer:
Laboratory studies suggest changing ocean chemistry will 1) harm life forms that rely on carbonate-based shells and skeletons, 2) harm organisms sensitive to acidity, and 3) harm organisms higher up the food chain that feed on these sensitive organisms.
Explanation:
These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which has different physical and biological characteristics.
23. An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red. Use this information to find the approximate pH of this solution.
Phenolphthalein is a weak acid and is colorless in solution. It is generally used to find out the endpoint of titration. As the An unknown solution is colorless when tested with phenolphthalein but causes the indicator phenol red to turn red it indicates the pH of the solution is 8.0 or above.
What is phenol red?Phenol red is an indicator whose color can exhibit a gradual transition from color yellow to red.
Phenol red is actually a water-soluble dye as is used as a pH indicator, changing from yellow to red over pH 6.6 to 8.0.
Thus, it can be concluded that the pH of the given unknown solution is in range 8.0 or above.

In a process called ____________ , genetic material is exchanged between homologous chromosomes. This occurs during this stage of cell division: ____________ .
In a process called crossing over, genetic material is exchanged between homologous chromosomes. This occurs during the prophase stage of cell division.
What is crossing over?Crossing over is the unique process by which genetic material is exchanged between the non-sister chromatids of homologous chromosomes.
Crossing over occurs in the prophase stage of meiosis and ultimately results in the formation of genetic combinations in offspring that are not present in the parents.
Therefore, the process called crossing over, genetic material is exchanged between homologous chromosomes and it occurs during the prophase stage of cell division.

b. Write a simple word equation to show how NPP is derived from GPP :
The net primary productivity (NPP) and the gross primary productivity (GPP) are related such that: NPP = GPP - Respiration
What is NPP?NPP refers to the net primary productivity of ecosystems. It is the amount of sugar made from photosynthesis when the amount of sugar burned during respiration has been deducted.
The total amount of sugar made during photosynthesis is the Gross Primary Productivity (GPP). This amount does not include the amount of sugar burned by respiration.
Thus, the equation relating the 3 variables would be:
NPP = GPP - Respiration

Answer:
False.
Explanation:
Just took the test. Also... It is false because Seafood Watch is not a legal authority and does not have the power to make fishing practices illegal. Seafood Watch is a program run by the Monterey Bay Aquarium that provides recommendations and guidance on sustainable seafood choices based on scientific assessments of fisheries and aquaculture practices. It aims to inform consumers and promote sustainable fishing practices but does not have legal authority to enforce regulations or make fishing practices illegal. That responsibility lies with governmental bodies and regulatory authorities.

Explanation:
Answer:
B. These resources are nonrenewable and will eventually disappear.
Explanation:
Fossil fuels take millions of years to form, but we mine and use them at a rate that is much faster than their replenishment time. That means that, at some point, we will use up all of the available fossil fuels before new ones can be formed.
Like the camel, many animals that live in soft sandy areas have large wide feet compared to their body size. The
large feet are an advantage in these environments because they -
are rapidly toughened by sharp sand grains
distribute body weight over a large area
allow rapid digging in the sand
Dreduce the vibrations caused by walking
Answer:
distribute body weight over a large area
Explanation:
This one's fairly simple. If you have large feet, then your body weight is distributed over a large area (you don't sink as much in sand). If your toes were small, massive body weight would sink the feet into sand.
