How does the ocean control weather and climate?
Answer:
Explanation:
The ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.

Reproduction refers to a biological process which typically involves living organisms (parents) mating to produce offspring.
Basically, there are two (2) main types of reproduction and these include;
Sexual reproduction.Asexual reproduction.Crossbreeding can be defined as the process of producing offspring by mating two (2) pure-breed living organisms (parents) of two (2) different breeds, varieties, or populations but within the same species.
For two heterozygous living organisms, the correct designation for predicting a cross between them is AaBb X AaBb.
In conclusion, the allele of a cross between two heterozygous living organisms are either dominant or recessive.

While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid with a ladder structure and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?
Answer:
Based on the information , the scientist concluded that the regarding nucleic acid is DNA (Deoxyribonucleic Acid) .The structure of DNA is attached below -:
Explanation:
PROPERTIES OF DNA -
In humans and almost all other species, DNA, or deoxyribonucleic acid, is an inherited substance. Almost every cell in the body of an individual has the same DNA. The DNA information is stored as a code consisting of four chemical bases: adenine (A), cytosine ( C), guanine ( G) and thymine ( T). In order to form units called base pairs, DNA bases pair up with each other, A with T and C with G. A sugar molecule and a phosphate molecule are both affixed to each base. Together, a nucleotide is called a base, sugar , and phosphate. Two long strands are arranged with nucleotides that form a spiral called a double helix. The double helix structure is much like a ladder, with the base pairs forming the rungs of the ladder and the molecules of sugar and phosphate forming the vertical sidepieces of the ladder.An significant DNA property is that it can duplicate itself or create copies of it. In the double helix, each strand of DNA will serve as a template for duplicating the sequence of bases. As each new cell requires to have an exact copy of the DNA present in the old cell, this is important as cells divide.Hence, the structure identified and conclude by the scientist is DNA (deoxyribonucleic acid). Thus, the structure of DNA is attached below.
Answer:
✓ The nucleic acid is DNA and would be found in the cell's nucleus

The Chihuahuan Desert of the United States and Mexico may be the most biologically diverse deser in the world. Extensive grazing has caused the flora and soil of this ecosystem to become unstable. How has biodiversity affected the sustainability of this ecosystem? A Biodiversity has put this ecosystem at risk of being less sustainable in the future.
B Biodiversity has not changed this ecosystem's level of sustainability.
C Biodiversity has prevented this ecosystem from being sustainable.
D Biodiversity has helped this ecosystem remain sustainable.
Answer:
A
Explanation:
Biodiversity has this ecosystem at risk of being less sustainable in the future, because it exposes the land to drought and other adverse conditions not supporting biodiversity in the future.
The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and urban areas throughout most of western United States and Florida, Central America, and most of South America.

What happens to carbon in plants when the plants die?(1 point)
The carbon is not released; it is lost.
The carbon will be released into the soil for use by the next generation.
The carbon is released into the air.
The carbon is released into the soil, but it is not used again.
Answer:
The carbon will be released into the soil for use by the next generation.
Explanation:
I finished the quiz and this was the correct answer.
When the plants die in that case the plants will die and the carbon from the body of the plants gets displaced in the soil. This is the end cycle of the nutrients of plants.
What is the location of carbon in plants ?It is the carbon compounds with the glucose containing the 6 number of carbons and the sugars containing total in 5 numbers of carbons.
As the plants gets the soil there body gets decomposed into the soil and later on the carbon that is absorbed from the atmosphere is given back to the soil and later on they together make the energy sources of carbon in the form of fossils which can be demonstrated later on as well.
And after plants get died, they get decayed by releasing carbon to atmosphere. The difference in the amount of carbon plants get absorbed and they do release is known as the net primary productivity. It is the direct measurement of the amount of how much plant matter is from the crops to the forests or ocean phytoplankton by the Earth produces.

What is a buffer? Why is it useful to cells?
Buffer are defined as substances that maintain a constant range of pH by the addition of the base and acid. It is important for cells to maintain the osmotic pressure and pH in the cell environment.
What is the importance of a buffer?In biology, the buffer has been the substances that are organic in nature and are used for regulating and controlling the level of the acids and bases that alters the pH of the system. It plays a crucial role in cells.
It is important for the cell to have a buffer solution, like bicarbonate ions in the blood that maintains the pH and the concentration of the hydrogen and hydroxide ions. It provides regulation of the osmotic balance and maintains the internal environment condition of the cell.
Therefore, the buffer is important for cells.

What two simple machines is a stapler made up of?
1. wheel and axle and lever
2. lever and pulley
3. wedge and screw
4. wedge and lever
Answer:
4. wedge and lever
Explanation:
Simple machines are mechanical devices which make our work easier. Examples are : lever, wedge, wheel and axel, pulley, screw and an incline plane.
A stapler is a made up of a level which is the handle part and a wedge which are the staples.
A pulley is a simple machine that has one or more wheels connected with a rope in a loop to make lifting of loads easier because it changes the direction of force applied/pull thus multiplying the force applied. A stapler does not have the wheel and the rope thus answer choice 1 and 2 are incorrect.
A screw is a simple machine that applies torque on a shaft to produce a large axial force on the load. It utilizes the conversion of rotational motion to a linear motion and a torque to a linear force. A stapler mechanism does not involve rotational motion or rotational force, hence answer option 3 is incorrect.
A stapler is made up of a combination of two simple machines: the wedge and the lever. The correct option is 4.
A stapler utilizes a wedge to perform its primary function. The wedge is the part of the stapler that drives the staple through the paper. It has a sharp, triangular shape that allows it to exert a large amount of force over a small area, making it easier to pierce through the materials.
The stapler also incorporates a lever mechanism. The lever is the long arm of the stapler that is pushed down to drive the wedge and staple into the paper.
By applying force at one end of the lever, a mechanical advantage is gained, allowing the user to apply a smaller force to produce a greater force output at the other end, making it easier to staple multiple sheets of paper together.
Therefore, The correct option is 4.
