a. Independent Variable:
b. Dependent Variable:
C. Control Group:
d. Constant:
It is an independent variable. Thus option A is correct.
What are the key difference between Independent and dependent Variable ?
The variable whose values are changed by researcher to get desired outcome is called an independent variable.
The variable, by changing its values to reciprocate change in the values of the independent variable is called the dependent variable.
The independent variable is act as the experiment controller whereas, the dependent variable act as experiment measure.
An independent variable is a cause whereas the dependent variable is an effect of that cause.
we can say in a linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable.
An independent variable does not rely on anything, while the dependent shows the effect, due to changes in independent variable.
Thus option A is correct.

What type of transport involves the movement of a substance from high to low concentration directly across the membrane? *
Answer:
Passive Transport
Explanation:
Diffusion is a type of passive transport. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm).
HURRY! Michael decides to bake bread one morning. He measures ingredients, mixes them together to make a dough, and cooks the dough in an oven. As the dough cook's, Michael observes the bread rising. Which of the following is evidence of the chemical change in Michael’s bread-making process?
Answer:
The bread rising as carbon dioxide is released.
Explanation:
Just did it
The trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.
What is Fermentation?Fermentation is defined as a metabolic process that produces chemical changes in organic substrates through the action of enzymes which is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Microorganisms such as bacteria and fungi have metabolic genes that allow them to produce enzymes to break down a variety of sugar metabolites.
Yeast and sugar produce carbonic gas through fermentation which is why as the yeast consumes the sugar, it produces alcohol (ethanol) and carbonic gas (carbon dioxide) as waste products, hence the carbon dioxide trapped in the dough lifts up,
Thus, the trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.

Science rejects any hypothesis not supported by __________________________ and the results of ___________________________ experiments. what are the blanks?
Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

what similarities would you expect to find in highly resilient ecosystems
Answer and explanation:
An ecosystem that is highly resilient is one that has the capacity to resist subjected damage by maintaining its normal patterns of biomass production and the cycling of nutrients. This damage can be anything from fires to deforestation.
A highly resilient ecosystem can be expected to adapt well to change, sometimes permanently, to survive indefinitely. For an ecosystem to be resilient, it has to be flexible and be able to adjust to uncertainty. Highly resilient ecosystems tend to have reproductive cycles, trophic cascades, and population connectivity - all of these characteristics give these ecosystems better chances of surviving different types of disturbances.

Explanation:
Structure has no apparent function in a species, but is fully functional in the species' ancestors.
a) true
b) false
Answer:
The correct answer would be - True.
Explanation:
In several organisms have structures, has no apparent role in the particular species and are residual parts from a past ancestor, but these structures were fully functional in the ancestors of the species. These structures are called vestigial structures or organs.
The example of such structures are, wings of the flightless birds, appendix of human and many other, all these structures has no function in the body of the individuals of the particular species but is fully functional in ancestors.
Thus, the correct answer is - true.
Why consumer in a food chain can’t get access to all energy in food chain?
Please I really need the answer
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up

3. What is another name or a sub-property of cohesion? Give an example of how this affects living
organisms
Answer:
Unity is the other name of cohesion.
Explanation:
The property of cohesion is to sticking together of something. The molecules of liquid stick together with the help of cohesion. This cohesion property is very important for plants because with the help of this property, plants take water through roots from the soil and the water molecules are stick together with the help of cohesion. If cohesion is not present then the uptake of water can not be possible.
