A confounding variable refers to an external effect, which modifies the influence of an independent and dependent variable. This extraneous effect is used to affect the outcome of an experimental design. The confounding variables can ruin the experiment and can generate unnecessary outcomes.
In the given case, confounding variables can be introduced by testing multiple hypotheses at a time and by using distinct kinds of soil in each of the samples.
The answer is D, sweating.
Homeostasis is where the body uses some mechanisms to maintain a optimum condition for the body to function. These conditions may include body temperature, blood glucose level etc.
Sweating is a mechanism that can help maintain the body temperature. During hot conditions, the sweat glands under the skin surface may produce sweat, which is then released to the skin surface. When the sweat is on the skin surface, they evaporate. During evaporation, heat energy is brought away from the skin as the sweat molecules that have a higher kinetic energy (=temperature) escaped from the sweat drop. The average temperature of the sweat is reduced.
Eventually, the temperature of the body is decreased and this help maintain the suitable temperature for the body to function.
Therefore, your answer is D, sweating.
I know its not d but it might be c or a
Answer:
Trees absorb carbon dioxide (CO2) during photosynthesis, in which they use sunlight to convert that CO2 into the sugars and energy they need to grow. ... Planting trees could therefore help mitigate climate breakdown, since they absorb CO2 as they grow, and the carbon remains stored until the wood decomposes or is burnt.
