In the area with the largest sea lamprey population, a few things are done to reduce and control this population. Lampricide, Currently, the primary method to control sea lampreys utilizes a lampricide, called TFM, that kills sea lamprey larvae in streams with little or no impact on other fish.   Barriers,Barriers have been constructed to block the upstream migration of spawning sea lampreys; most barriers allow other fish to pass with minimal disruption. Barriers have eliminated lampricide treatment on some streams and reduced the stream distance requiring treatment on others. The Sterile-Male-Release-Technique, The sterile-male-release-technique aims to reduce the success of sea lamprey spawning. Each year male sea lampreys are collected and sterilized. When they are released back into streams the sterile males compete with normal males for spawning females. Lastly trapping, Sea lamprey traps are operated at various locations throughout the Great Lakes, often in association with barriers. Traps are designed to catch lampreys as they travel upstream to spawn.

During the day what typically happens to air pressure? During the night what typically happens to air temperature?
dolphi86 [110]
A sea breeze describes the wind that blows from the ocean inland towards land. This breeze occurs most often in the spring and summer months because of the greater temperature differences between the ocean and nearby land, particularly in the afternoon when the land is at maximum heating from the sun. 
During the day, the sun heats up both the ocean surface and the land. Water is a good absorber of the energy from the sun. The land absorbs much of the sun’s energy as well.  However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, the high surface pressure will form because of the colder air. To compensate, the air will sink over the ocean. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean.
At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too.  This can be compared to a blacktop road. During the day, the blacktop road heats up and becomes very hot to walk on. At night, however, the blacktop has given up the added heat and is cool to the touch. The ocean, however, is able to hold onto this heat after the sun sets and not lose it as easily. This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land. This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.

natta225 [31]
In simple terms, there are 4 categories of protists in basic biology characterized by their type of locomotion.

Locomotion by pseudopods or "false feet" is characteristic of ameobas (i.e. <em>Entamoeba histolytica</em>). Locomotion by papillary projections from the cell membrane called "cilia" is characteristic of <em>Paramecium </em>species. Locomotion by whip-like structures that propel the organism called "flagella" is characteristic of <em>Euglena </em>species. 
<em />
Lastly, protists that do not have locomotive organelles are exemplified by <em>Plasmodium </em>species, the etiologic agent of malaria.

borishaifa [10]

The active hyperemia is the consequence of dilation of arterioles and the resultant influx of blood in the capillaries, which occurs during blushing or excercise.

<u>Explanation:</u>

The rise in organ blood circulation correlated with an organ or tissue having elevated metabolic activity is understood as active hyperemia. An illustration of active hyperemia is the rise in blood flow that follows muscle contraction, also named skeletal muscle activity or responsive hyperemia.

It typically occurs when blood is needed by the organs more than normal. Your blood vessels are expanding to improve blood running in. Reactive hyperemia is the blood circulation reaction to occlusion of blood flow, while active hyperemia is the blood flow result of increased metabolic activity of the tissue.
