1 answer:
a_sh-v [17]2 years ago
6 0

Answer:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0)

y-int: (0, 2)

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0) ==> When y=0

y-int: (0, 2) ==> When x=0

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 largest organ of the human body is the skin. The total external skin area of the average human covers an area of approximate
masha68 [24]

Answer:

Body\ surface\ area=\sqrt {\frac {Weight\times Height}{3600}}

Explanation:

Skin covers all the body surfaces. The purpose of the skin is protect the body against infection, injury, heat or cold and also to store water and vitamins.

Body surface area is  measure of surface area of the human body. It is measured in m^2.

<u>There are many ways to measure the skin surface area of the body but the formula which is widely used is Mosteller formula, which is:</u>

Body\ surface\ area=\sqrt {\frac {Weight\times Height}{3600}}

Which characteristic distinguishes fungal cells from plant cells
sertanlavr [38]

Answer: Feeding behaviors, trophic levels, cell wall composition, and their organelles distinguish fungi from plants.

Explanation:

While plants and fungi are both eukaryotes, they differ in terms of feeding behaviors, trophic levels, cell wall composition, and their organelles.

  • Cell walls: both are non-chain polysaccharides (sugars) that function as structural support; yet fungal cell walls are composed of chitin while plant cell walls are made up of cellulose

  • Feeding: fungi secrete compounds that digest their food sources before they can take in nutrients and they store food as <em>glycogen; </em>while plants do not require a means of pre-digesting food and store their food as <em>starch.</em>

  • Organelles: plant cells contain <em>chloroplasts</em>, small green structures with chlorophyll that causes their characteristic coloration. Unlike plants, fungi do not photosynthesize to make their own food or contain chloroplasts.

  • Trophic level: are strictly <em>heterotrophs or decomposers, </em>depending on other organisms for survival. Their chloroplasts enable them to carry out photosynthesis, thus they are <em>autotrophs or producers. </em>

stepladder [879]

The fatty acids in the tail of a phospholipid molecule are non-polar and hydrophobic.

Fats that you take in from your food is used to build membranes. Membranes can be represented by models such as The Fluid Mosaic Model, which displays the phospholipid bilayr, and other tissues on the membrane.
