Answer:

You just posted his one? Credit to: Vermont Legislative Research Shop

Explanation:

If you need extra resources: Lawn and garden chemicals, such as fertilizers enter the groundwater in two ways. In the first method, the chemicals can enter the groundwater by rainwater into a stream as runoff. This is especially problematic in urban environments where hard-surfaced roads allow rainwater to move over them without benefit of soil acting as a filter (Rosen and White, 1999). The water in streams replenishes groundwater, so the chemicals are absorbed into the groundwater as well. The second method of contamination is through leaching, which is the downward movement of a substance through the soil. The fertilizer may also dissolve into the surface water, which recharges the groundwater (Virginia Cooperative Extension, 1996).  Nitrate is highly soluble and readily leaches into groundwater. Water with over 10 parts per million nitrate-nitrogen can cause methemoglobinemia, an inability to use oxygen in infants. The nutrient phosphorus harms clear, free water by creating algal blooms. This process, known as eutrophication, turns the water green, clouds the water, causes odor problems, and depletes the oxygen for fish and other species, effectively suffocating them (Lake Champlain Basin, 1998).  To ensure that the groundwater does not get so contaminated as to be unhealthy, in 1986 the Department of Food and Markets implemented the Pesticide Monitoring Program. The goal of this program is to test wells in agricultural areas to help farmers learn about practices that prevent pesticides from leaching into the groundwater, and to conserve the nutrients in fertilizers and manure in the soil. This program is funded by fees taken from companies that sell pesticides and fertilizers in Vermont (Vermont Department of Agriculture, Food and Markets, 1998).

Select the correct statement about the three-chambered hearts of amphibians and nonbird reptiles. A scheme of blood circulation
Soloha48 [4]

Answer:

The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.

Explanation:

In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.

Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.

What evidence best supports the conversation during photosynthesis?
lions [1.4K]

The evidence that best supports conversation during photosynthesis is: Light energy is converted to chemical energy during photosynthesis ( A )

Photosynthesis is the process whereby plants make use of water and carbon dioxide found in the atmosphere to transform/convert the light energy from the sun into chemical energy.in the process of synthesizing food  

The products of photosynthesis include oxygen and glucose while the conversion during photosynthesis takes place when the chloroplast absorbs the light energy from the sunlight and converts it another form of energy ( chemical energy ).

Hence we can conclude that The evidence that best supports conversation during photosynthesis is ; Light energy is converted to chemical energy during photosynthesis.
