The independent variable should stay constant because each group should be completely different to do an experiment while it is being conducted.
What are variables?
The variables are defined as any characteristics, number or quantity which can be measured . They can also be called as a data item . They are called as variables because they can vary and can have variety of values.
There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variables which does not change
Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Which type of resources form much more slowly than we use them? A: reusable B: renewable C: nonreusable D: nonrenewable
The type of resources from much more slowly than we use them is non-renewable resource. The correct option is D.
What are nonrenewable resources?A non-renewable resource is a natural resource that cannot be replaced quickly enough by natural means to keep up with consumption.
Carbon-based fossil fuels are one example. With the help of heat and pressure, the original organic matter is converted into a fuel such as oil or gas.
Nonrenewable energy sources are not only affecting our planet's atmosphere by increasing greenhouse gas emissions.
Coal and oil combustion emits particles that can pollute the air, water, and land. Some of these particles are captured and stored, but many are released into the atmosphere.
The use of fossil fuels also disrupts Earth's "carbon budget," which balances carbon in the ocean, earth, and atmosphere.
Thus, the correct option is D.

Place each land feature in the correct category based on the process that causes its formation
•Oxbow lake. Eroison by rivers
•Alluvial fan
•Delta
•Meander. Deposition by rivers
•Waterfall
•Flood plain
Deposition by rivers generates alluvial fans and deltas. Moreover, erosion by rivers generates waterfalls, flood plains, oxbow lakes and meanders.
An oxbow lake is a lake located in a meandering channel, and therefore on a floodplain.
Alluvial fans are accumulations of sediments created as flowing water bodies interact with mountains or hills.
A delta is a formation of land composed of sediments located in the mouth of the river.
A waterfall is a point in a river where water spills suddenly downward.

Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol
In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.
Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.
Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.
In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

A drug that affects both divisions of the autonomic system is going to bind to, or block the nicotinic neurotransmitter receptor
A chemical that the body produces to interact with those receptors is called an endogenous chemical, whereas a chemical introduced to the system from outside is an exogenous chemical.
Nicotine is not a drug that is used therapeutically, except for smoking cessation. When it is introduced into the body via products, it has broad effects on the autonomic system.
The nicotinic receptor is found on all autonomic ganglia.

For which one of the following functions is parenchyma tissue particularly suited?
A. Reinforcement and support C. Elasticity
B. Exchange of gases D. Formation or root hairs
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).

In the citric acid cycle, the enzyme succinate dehydrogenase catalyzes a reversible reaction using FAD/FADH2 as an oxidizing/reducing agent. Which of the following statements best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions?
A. FAD has no reduction potential when it is enzyme-bound.
B. FAD can be reduced by the sequential addition of one hydrogen at a time.
C. FAD/FADH2 is covalently bound to succinate dehydrogenase.
D. The change in the biochemical standard reduction potential is small.
The statement which best explains how the redox component of this reaction contributes to the reaction's ability to be reversible under cellular conditions is; Choice D: The change in the biochemical standard reduction potential is small.
Discussion:
A reversible process is one in which the system and environment can be restored to exactly the same initial states that they were in prior to when the process occurred, if we go backward along the path of the process.
However, the necessary condition for a reversible process is therefore the quasi-static requirement.The quasi-static requirement in this case is that the change in the biochemical standard reduction potential is small.Read more:

How would a biomagnification “pyramid compare with an energy pyramid?
Answer:
Energy pyramid depicts flow of energy in the ecosystem: source of all energy in ecosystem is the SUN. Producers are only organisms in ecosystem who can trap the solar enrgy. So base of energy pyramid is always wide. A biomass pyramid shows the total dry mass of all living organisms at each trophic level.
Explanation:
Because the amount of the pollutant increases as it goes up the food chain, the biomagnification pyramid is inverted whereas the energy pyramid is consistently upright.
What is biomagnification?Biomagnification is the amassing of a chemical by an organism as a result of exposure to both food and water, resulting in a concentration that is higher than what would have been expected from equilibrium and higher than what would have occurred with only water exposure.
When dangerous chemicals like DDT that remain in the environment are indirectly absorbed by living things through food, this process is known as biomagnification.
When a higher-order organism consumes a lower-order organism that contains such compounds, the chemicals may accumulate in the higher-order organism.
The biomagnification pyramid is upside down because the amount of the pollutant increases as it moves up the food chain. The energy pyramid, however, is always upright.
Thus, this can be the comparison between the energy pyramid and biomagnification.

Mrs. W. is 68 years old and lives alone. She moves very slowly and does not respond verbally to what others say. She sometimes mumbles to herself. Her face is expressionless. She seems confused by her surroundings. She is accompanied by her daughter, who is highly observant and an accurate reporter of Mrs. W.’s past medical and psychosocial history. What possible Noncognitive Disorders could Mrs. W have?
The non-cognitive disturbances that Mrs. W. could have related to some dementia are psychosis, personality change, lack of rhythm, deficit in emotional responses, mental confusion.
It is important that the patient in these conditions is continuously assisted, to avoid situations that put her safety at risk.
An elderly woman like Mrs. W, who already has significant evolution of non-cognitive disorders, must have an effective medical apparatus and a tutor willing to help with care and daily activities.
Ideally, caregivers should develop optimal communication skills for patients with these disorders, such as a calm and gentle tone, provide the individual with a peaceful environment without too much noise or other disturbances, as well as being considerate and not neglecting the individual's needs.
