Outbreaks of giardiasis have occurred in numerous places where drinking water treatment plants did not provide proper filtration and purification of fecally contaminated water supplied to the public. Garidia is a protist that lives in the intestines of warm blooded animals and is highly resistant to chlorination due to the presence of cysts.

What is one of the functions controlled by the cerebellum? A. balance B. digestion C. respiration D. memory
Brums [2.3K]

Answer:

A. Balance

Explanation:

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. It is also important for learning motor behaviors.

What are similar structures that evolved independently called?
Ilia_Sergeevich [38]

Answer:

Analogous structures

Explanation:

These structures are similar but not derived from the common ancestor like homologous structures. Analogous structures are formed as a result of convergent evolution-type of evolution in which organisms develop on similar way but independently. An example of analogous structures are wings. Birds, insects and bats all have wings, with the same purpose (flight) but they evolved in their own way.

Compare actions of cocaine amphetamines and nicotine
Nookie1986 [14]
Nicotine on direct application in humans causes irritation and burning sensation in the mouth and throat, increased salivation, nausea, abdominal pain, vomiting and diarrhea. Predominant immediate effects consist of increase in pulse rate and blood pressure. Nicotine also causes an increase in plasma free fatty acids, hyperglycemia, and an increase in the level of catecholamines in the blood. There is reduced coronary blood flow but an increased skeletal muscle blood flow. The increased rate of respiration causes hypothermia, a hypercoagulable state, decreases skin temperature, and increases the blood viscosity.

For amphetamine the immediate effects are quicker reaction times, feelings of energy/wakefulness, excitement, increased attentiveness and concentration, feelings of euphoria. Side effects of amphetamines can include heart palpitations, dry mouth, headache, hostility, nausea, cognitive impairment, severe anxiety, lack of appetite, teeth grinding, dizziness, increased heart rate, heart palpitations, rapid breathing rate, hypertension (high blood pressure), increased body temperature, erectile dysfunction, irregular heartbeat.

Cocaine causes a short-lived, intense high that is immediately followed by the opposite intense depression, edginess and a craving for more of the drug the side effects are Loss of appetite increased heart rate, blood pressure, body temperature, contracted blood vessels increased rate of breathing, dilated pupils, disturbed sleep patterns, nausea, hyperstimulation, bizarre, erratic, sometimes violent behavior hallucinations, hyperexcitability, irritability, tactile hallucination that creates the illusion of bugs burrowing under the skin, intense euphoria, anxiety and paranoia, depression, intense drug craving, panic and psychosis, convulsions, seizures and sudden death from high doses (even one time)

What kind of currents bring warm air to land?
Zinaida [17]

Answer: A warm current is just the reverse. A warm current is moving away from the Equator toward the poles. The water in a warm current is warmer than the surrounding water.

Explanation: The surface water temperature varies considerably between the Equator and the poles. As the ocean water is distributed across the Earth's surface by drifts and currents (see the infrared satellite photo of the warm Gulf Stream moving north along the east coast of Florida), warm water from the lower latitudes is moved into the higher latitudes and cold water is moved Equatorward. If you will remember, we noted in the section on Latitude that this redistribution of heat by ocean water is one of the major ways excess energy is moved poleward (and cold water is moved Equatorward).

I hope this helps, good luck
