The answer is plankton are floaters. Plankton and nekton are both marine aquatic organisms. The main difference between the two is that plankton tend to float and be carried by water currents while nekton are organisms that swim against the current of the water. Plankton are passive swimmers while neekton are active swimmers.

Several bodily responses are described below. For each response, determine what caused the change in
EastWind [94]

Answer:

  1. Body starts to sweat: The core body temperature exceeded the set range of 35 degrees to 41.5 degree celsius
  2. Breathing rate increases: Cells are not receiving adequate oxygen to produce adequate energy.
  3. Amount of saliva produced changes: Saliva is produced in response to pH changes in the mouth or the intake of food.
  4. Body starts to shiver: Core temperature dropped below the set range of 35 to 41.5 degree celsius.

Explanation:

Homeostasis:

Homeostasis is the physiological process of regulating the internal environment of the body against fluctuations in the external environment.

Homeostasis systems in the body follow the following basic scheme (from 1 to 4):

  1. Stimulus
  2. Sensor
  3. Control
  4. Effector

Various control centers in the body sense varying body conditions and in turn activate certain effector mechanisms to regulate the changing conditions.

Thermoregulation:

  • Thermoregulation is the control and regulation of the optimum core temperature of the body between the range 35 to 41.5 degree celsius.
  • The control center is the hypothalamus, a part of the brain that receives signals from receptors in the body and initiates the appropriate response.
  • If the core temperature exceeds the optimum range, two mechanisms are initiated:
  1. The blood vessels towards the skin and extremities dilate, increasing the blood flow, allowing heat loss to the environment.
  2. Sweat glands are activated, evaporation of sweat produces a cooling effect.
  • If the core temperature decreases, again, two mechanisms are activated:
  1. Blood vessels to the extremities constrict to prevent heat loss; those towards the core dilate to provide maximum heat to the internal organs.
  2. Shivering mechanisms (involuntary muscle contractions) are activated that generate heat.

Respiratory Homeostasis:

During exercise or strenuous physical activity, our cells need to produce a large amount of energy through cellular respiration. Since, cellular respiration requires oxygen, more and more oxygen needs to be supplied to the cells. A low oxygen signal detected by the hypothalamus (control center in the brain) increases the breathing rate to ensure that sufficient oxygen reaches the cells.

Oral homeostasis:

The salivary glands maintain the homeostasis of the oral cavity. Saliva is not produced in response to food but to maintain the pH of the oral cavity to protect the teeth and enamel. Saliva contains the enzyme amylase which digests carbohydrates in the mouth. Therefore, the production of saliva increases in response to smell, sight and taste of food.

The graph below compares the rates of reaction of a burning candle and an exploding firework.
marusya05 [52]

Answer:

The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.

Explanation:

The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.

Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.

In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.

EFFECTS OF NUTRIENTS (IN FOOD) ON THE STRUCTURE AND FUNCTION OF THE NERVOUS SYSTEM: UPDATE ON DIETARY REQUIREMENTS FOR BRAIN. PA
klemol [59]

It main aim to give an overview about the effect of dietary nutrients on the structure and functions of brain. Brain which is elaborated from substances present in the diet such as vitamins, essential amino acids, fatty acids, omega-3 , etc.

Micronutients ( vitamins, trace- elements) have been directly evaluated in the setting of cerebral functioning. Nervous tissues use glucose to produces the energy and implies the presence of vitamin B1 , which perform cogitative functions, specifically in elderly. Vitamin B9 , which preserve the brain during its development .

Genetic potential of children for their physical growth and mental development may compromised due to deficiency of micronutrients. Their poor nutritional status are exposed to alterations of mental and behavioral functions that can corrected by dietary measure.
