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.

The appropriate question is:
What role do aquifers play in the water cycle?
Answer:
The correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.
Explanation:
Dr. Smith has found the bird that he considered as new species however Dr. Wilson said he will only be convinced if DR. smith could find several members of the same species. Dr. Wilson seems to be sure before considering the bird that Dr. smith found as the new species. It is because he wants to sure if it's not an unusual example of the pre-described species.
Thus, the correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.

Explanation:
Answer:
When energy flows from one trophic level to the next trophic level most of the energy lost as heat in the process.
Explanation:
The food chain is transfer of energy in the form of food from one trophic level to next in an ecosystem.
Energy flows from at each trophic level when organism of higher level consumes organism of the lower level.
Energy flows at each trophic level by 10% Rule which states that only ten percent of the energy will be transferred on at each trophic because of the following reasons-
1. Energy is lost in the form of heat at each step
2. Only consumable energy by organisms is transferred at the trophic level.
3. Energy is lost through different biological processes such as respiration.
The average age at which an infant can sit unattended is approximately 5-7 months.
The baby will reach gross motor milestones in the following order:
(1) sitting up without assistance
(2) crawling on hands and knees
(3) standing with aid
(4) walking with assistance
(5) standing without support and
(6) walking without support.

Explanation:
Heart attacks reduce blood flow to the heart and cause coronary artery disease.
Coronary artery disease can reduce blood flow to the heart and cause heart attacks.
Heart attacks occur when coronary artery disease is treated.
coronary heart diseases occur when the arteries are blocked with fatty deposits
so there is less blood flow to the heart. less oxygen and nutrients to the heart. this leads to heart attack. coronary diseases lead to attacks
