Answer:

Explanation: The town in the Finger Lakes region should promote the solution of decreased motor boat traffic on the lake. Acidification is mainly caused by the high levels of carbon dioxide that enter the water from the atmosphere, and motor boat traffic can worsen this by increasing the amount of carbon dioxide in the air. Reducing motor boat traffic on the lake would help to decrease the amount of carbon dioxide entering the water, and thus reduce acidification. The other solutions listed (increased introduction of zebra mussels, decreased use of CFCs, and protecting fish species) may have other environmental benefits, but they are not directly related to reducing acidification.

Statement which is not associated with transient ischemic attack (TIA)  is d)The sudden death of brain tissue caused by ischemia. So, correct option is d.

A transient ischemic attack (TIA), ordinarily known as a little stroke, is a minor stroke whose observable side effects as a rule end in under 60 minutes. TIA causes similar side effects related with strokes, for example, shortcoming or deadness on one side of the body, unexpected darkening or loss of vision, trouble communicating in or grasping language, slurred discourse, or disarray.

All types of stroke, including TIA, result from a disturbance in blood stream to the focal sensory system. A TIA is brought about by a brief disturbance in blood stream to the mind, or cerebral blood stream (CBF). The essential distinction between a significant stroke and the TIA's minor stroke is how much tissue demise (localized necrosis) can be distinguished subsequently through clinical imaging.

Hence,correct option is d.

Answer:

Explanation:

Wind and other weathering conditions wash away sediment on land, depositing it in bodies of water. For this reason, fossils of sea creatures are more common than those of land creatures.

Nearly all fossils we find - around 99% - are from marine animals such as shellfish and sharks. This is because they lived in the sea, where sand or mud could bury their remains quickly after they died.

These phases are prophase, prometaphase, and metaphase,  Cytokinesis is the final physical cell division and is considered the sixth phase of mitosis.

Cytokinesis begins in the phase of cell division. and ends in telophase, extending completion as the next interphase begins. The first obvious change of cytokinesis in an animal cell is the sudden aspect of a pucker, or cleavage furrow, on the cell surface.

Mitosis and each of the two meiotic divisions result in two unrelated nuclei contained within a single cell. Cytokinesis performs a crucial process to separate the cell in half and ensure that one nucleus ends up in each daughter cell.

So we can conclude that Cytokinesis, the division of the cytoplasm to form two new cells, overhangs with the final stages of mitosis.

Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.

Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.

Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.

Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.

Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.

Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

The particles of the substance initially had high Kinetic Energy.​

Gas particles move quickly in all directions and regularly collide with one another and the container's side. The particles gather kinetic energy and accelerate as the temperature rises. The particles' real average speed is influenced by their mass and temperature.

In liquids, particles are quite close together and move with random motion throughout the container. Due to the closer proximity of the particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.

When the temperature is increased from 25 degrees to 35 Celsius degrees Celsius, the effect on oxygen production in the light is dependent on the plant species being observed.

Some plants experience an increase in oxygen production with a rise in temperature, while others experience a decrease. The reason for this variation in response is due to the different photosynthetic pathways that plants utilize. Plants that use the C3 photosynthetic pathway generally experience an increase in oxygen production with a rise in temperature. This is because the C3 pathway is less efficient at high temperatures, causing an accumulation of excess energy that is channeled into oxygen production. On the other hand, plants that use the C4 and CAM photosynthetic pathways typically experience a decrease in oxygen production with a rise in temperature. This is because these pathways are more efficient at high temperatures and are better able to channel excess energy into carbon fixation rather than oxygen production. In summary, the effect of temperature on oxygen production in the light is dependent on the photosynthetic pathway used by the plant. C3 plants typically experience an increase in oxygen production, while C4 and CAM plants experience a decrease. However, it is important to note that these responses can vary depending on the specific plant species and environmental conditions.

The correct answer would be - The lithosphere influences the atmosphere and biosphere .

Explanation:

The mountains of the Sierra Nevada play the role of a barrier that blocks the air or wind that brings the clouds filled with water to eastern California and Nevada as it can not pass the mountains and reach the other side of mountains which cause less or no rain to this region.

Rain is a very important aspect for the region to be less diverse in plants and animals as most of them require water but as it is described there is no or very little precipitation so it becomes desert.

This makes it an example of the lithosphere influences the atmosphere and biosphere .
