I looked it up and it should be D. Nerve cells :)
Answer:
Explanation:
A sequence of flowing lava, pyroclastic flows, volcanic eruptions, caldera-forming events, and earthquakes changed the landscape of Yellowstone forever. The pressure exerted by the magma chamber has resulted in measurable ground deformation in certain parts of Yellowstone known as resurgent pressure domes.
Fire Activity also causes the Yellowstone to change. As the number of very large wildfires and total acres burned annually increases, there is an increasing frequency of warm spring and summer temperatures, reduced winter precipitation, and early snowmelt in the Western United States during the last 20 years.
In 1995, the wolf population increased in Yellowstone, causing the deer population to decrease and to change their behavior. When threatened by wolves, deer graze less and move about to aerate the soil.
In the 70 years since the wolves left Yellowstone, the entire ecosystem had collapsed into chaos, with coyotes running riot, and elks overgrazing willows and aspens. Without those trees, songbirds declined, beavers could not build their dams, and riverbanks eroded.
Answer:
It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.
We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.
We should give the awareness to the general public related to decrease the recreational fishing impact.
Commercial fishing must be ban until we reaches the sustainable level of fish.
There must be place international limits to every country related to limited number of fish they can take.
To keep in the stored enzymes so it can keep synthesizing at night, even when there is no sunlight. -- Stomata serve two main functions - they allow carbon dioxide to reach the cells in the leaf where the majority of photosynthesis takes place and they allow water to be transpired out off the leaf. During the day, stomata are generally open to allow photosynthesis to take place as quickly as possible. At night, when the lack of light means photosynthesis can't take place, many plants close their stomata to reduce water loss. There is one group of mainly desert plants, known as CAM plants, that keep their stomata closed during the day when water loss would be greatest, and open them at night, using a biochemical method to effectively store carbon dioxide in the leaf overnight.
Answer:
23 chromosomes.
Explanation:
Human gametes have 23 chromosomes.Reproductive cells (gametes) are haploid - they have half the number of chromosomes as a body (somatic) cell. HOPE IT HELPS:)
