b)The experiment will lack a purpose.
c)The experiment will not be repeatable.
d)The experiment will not have variables.
Answer;
The experiment would lack a control group
Explanation;
-An experiment deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response.
-Experimental design involves taking time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.
-A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
B. The mutations could be treated by chemotherapy.
C. It occurs in somatic cells and thus are not usually transmitted to descendants.
Answer: Obviously the anwser is C. It occurs in somatic cells and thus are not usually transmitted to descendants. Hope this Helps :D
b. natural selection.
c. descent with modification.
d. acquired characteristics.
Answer: Artificial selection.
Explanation: Artificial Selection can be defined as the intentional reproduction of the individuals that have the desired trait. The organism having the desired character breed together to give rise to the individual having the desired trait.
The dairy farmer choose to breed the cows that give most milk. This is the desired character that we want in the offspring.
Well, i took the test and i put artificial selection and got it right. The definition of artificial selection is "The breeding of plants and animals to produce desirable traits" So the answer is A
An aquifer is the underground layer which is composed of water-bearing rocks. Sandstone, sands, gravel, and other sedimentary rocks are examples of water-bearing rock. They are permeable and have openings that gases and liquids can pass through. In a water cycle, a water will be added to the aquifer during the precipitation.
Aquifers store and transmit groundwater, regulating water movement in the water cycle. They provide storage, regulate base flow, support transpiration, and aid in water purification.
Aquifers are underground porous rock formations that store and release groundwater, playing a crucial role in the water cycle. During periods of excess water, they store water that percolates through the soil, recharging through precipitation. In times of scarcity, aquifers discharge water slowly, sustaining base flow in streams and rivers, thus maintaining ecosystems.
They also contribute to transpiration by supplying water to plants, supporting their growth and the release of moisture into the atmosphere. Additionally, as water travels through aquifer layers, natural filtration occurs, enhancing water quality. Proper aquifer management is vital for sustainable water resources, ecosystem health, and human consumption.
