Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion provides the best explanation for why algae proliferate in neighborhood ponds?
Answer:
Excessive synthetic fertilizer that washes into ponds may be the reason for which algae become so abundant.
Explanation:
Algal blooms that feed on fertilizers can deplete oxygen in water, thereby producing inhospitable ponds. In this regard, it has been shown that the runoff of fertilizers from farms (which are rich in nitrogenous matter) may cause algae to become abundant in coastal environments, depleting oxygen in the water and killing the living organisms that inhabit these areas.

Four children pull on the same stuffed toy at the same
time, yet there is no net force on the toy. How is this
possible?
Answer:
The forces the children are exerting on the object balanced one another.
Explanation:
Equal forces acting on an object in opposite directions.
Hope this helps!
Answer:
Sample Response: Forces are either positive or negative vectors, depending on the direction in which the force is acting. The net force is the sum of all of the forces acting on an object. If the children pull on the toy with the same force in opposite directions, the forces will be perfectly balanced and cancel out, leaving a net force of zero.

proteins in the plasma membranes help aid in the formation of several thihngs like muscles, hair, and amino acids which is made from transcriiption of the RNA from the DNA
Large complicated molecules crucial for cell construction and function are known as proteins. They are made up of various amino acids connected by the peptide bonds.
They are an important element of the cell layer as they carry nutrients across the membrane.To find the function of membrane proteins tests like fluorescence recovery following photobleaching can be used to determine the mobility of the proteins.Another method of nitrocellulose blots treatment by glutaraldehyde can be employed.To learn more about plasma membrane proteins follow the link:

what kind of bond forms when atoms in a molecule do not share their electrons equally
a. an ionic bond
b. a metallic bond
c. a polar bond
d. a hydrogen bond
Answer:
A polar bond
Explanation:
Ionic bond don't share but one atom accepts electron while the other gives away electron Metallic bond are held by metals and they contribute their outer valency electrons to the electron cloud thus making them positive A polar bond deals with the share of unequal electron (I.e. Covalent polar bond) A hydrogen bond is covalently bonded to highly electronegative elements of small atomic sizeAn energy-rich organic compound needed by organisms is:
(1) water
(2) oxygen
(3) salt

Which of the following was the leading cause of global fossil carbon emissions in 2004?
a. petroleum
b. coal
c. natural gas
d. cement production
Answer:
The answer is a. petroleum
Explanation:
I just took the test and got it right.
The leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.
What is Carbon emission?Carbon emission may be defined as the process of liberation of greenhouse gases like carbon dioxide and/or their precursors into the atmosphere over a specified area and period of time. These emissions are significantly contributing to climate change across the world.
When it comes to the global fossil carbon emissions in 2004, the major cause of that was due to petroleum. During that time, people utilize a large amount of petroleum in burning activities. This stimulates the rate of carbon emission in the entire atmosphere which is harmful to the health of living organisms.
Therefore, the leading cause of global fossil carbon emissions in 2004 was petroleum. Thus, the correct option for this question is A.

the answer is Nonmetal
The fossils of a few organisms are shown below. The first image is a bird, the second image is a dinosaur, and the third image is an Archaeopteryx. The dinosaur fossils were obtained from the lower sedimentary layer, and Archaeopteryx was found above it. The fossils of the bird were found on the topmost layer, which suggests that they’re the_____ . This information also suggests that Archaeopteryx _______.
-21 POINTS-
Answer:
They're the Youngest. This information also suggests that Archaeopteryx was once thought to be the oldest known fossil bird.
Explanation:
Hope this helps.
Based on the principle of superposition, we can conclude that the topmost layer is the youngest. Hence, the fossil of birds is the youngest, while Archaeopteryx is younger than dinosaur fossil.
According to the principle of superposition, sedimentary deposits are layered such that, the oldest layer is at the bottom and the youngest is the topmost layer.
Hence, dinosaur fossil are the oldest, followed by Archaeopteryx, then birds.
