which characteristic of living organisms is responsible for the production of oxygen in the leaf of a plant exposed to sunlight.
Answer:
Photosynthesis.
Explanation:
Photosynthesis is a characteristic of living organisms and it is typically responsible for the production of oxygen in the leaf of a plant exposed to sunlight. It is a chemical process used by plants to obtain food from sunlight.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the cell organelle where energy from nutrients is released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Drop a paper a piece of thermocol and a piece of plastic from a height of 10 to 15 feet not the time for each object to hit the ground why does paper take more time than thermocol and thermocol more than the plastic piece make the paper to fell down in such a way that it should hit the ground before all of them and how does it happen
Answer:
The paper takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.
The thermocol takes more time than the piece of plastic because it experiences a greater air resistance.
The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it and then giving it an initial velocity by throwing it downwards.
Explanation:
Objects falling freely due to the force of gravity alone are accelerated downwards at a constant value 9.8 m/s². This acceleration due to gravity is constant for all objects on the earth's surface and is independent of the mass of the objects.Therefore, when objects are release from the same height and allowed to fall freely under gravity, they are accelerated downwards to the same extent and are expected to hit the ground at the same time. However,due to the resistance of the air through which the objects are falling, they may hit the ground at different times depending on the shape of the falling objects.
Objects which have a greater surface area or volume per unit mass will experience a greater air drag or resistance and therefore, will take a longer time than objects of similar mass with a smaller volume or surface area.
The paper has a greater surface area per unit mass than the piece of thermocol, therefore, it takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.
The thermocol has a greater surface area per unit mass than the piece of plastic, therefore, it takes more time than the piece of plastic because it experiences a greater air resistance.
The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it, thereby reducing its surface area per unit mass it and then giving it an initial velocity by throwing it downwards.

16. Control group: Subject A
17. Independent (manipulated) variable: Type of powder
18. Dependent variable: Itching time
19. Explain whether the data supports the advertisement´s claims about its product. Yes, it does.
Explanation:
Control group: The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study (in this case, the new product), from the results that might be a consequence of other factors. The control group must be selected from the same population as the treatment group. Data from an experimental group are compared with the data from a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups. In this case, the experimental group is subject B.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the type of powder is the independent variable. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, inching time is the dependent variable, that depends on the type of powder used. The data does support the advertisement´s claims about its product. The effect of the new product lasts 50% more than the original product. The old powder produced itching for 30 minutes, while the new product produced itching for 45min (15 more minutes, 50% more).What's a energy pyramid

An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N

What is fossil fuel?
Fossil fuels has been result of the biological processes as heat and pressure from the Earth's crust that decomposed these organisms into one of the three main kinds of fuel and these are oil which is also called petroleum, natural gas, or coal.
The origin of the fossil fuels has the anaerobic decomposition of the buried lifeless organisms, that containing natural molecules is created through photosynthesis. The conversion from those materials to excessive-carbon fossil fuels commonly require a geological method of millions of years.
Biological methods are defined as the processes that are very crucial for an organism to live, as well as that shape its capacities for interacting with its surroundings. The organic processes has been made of many chemical reactions or the different events that use to concerned within the persistence as well as the transformation of lifestyles forms.
Therefore, Biological approaches either aerobic or the anaerobic which is based upon the environmental necessities of the microbial consortia.
