Explain how environmental factors affect the rate of transpiration in flowering plants​
Igoryamba

Explanation:

there are a couple of environmental factors that affect the rate of transpiration. they include:

I) wind:in a windy environment there is easy movement of moisture hence it does not accumulate on the leaf surface. this helps to increase diffusion gradient between the intercellular spaces in the leaf and in the environment there4 the rate of transpiration is increased. in a calm environment moisture accumulates on the surface of a leaf there4 reducing the diffusion gradient there4 reducing the rate of transpiration

ii) atmospheric pressure :in low lands there is high atmospheric pressure than in the highlands. the more the atmospheric pressure the more the pressure exerted on the cells of the leaves there4 reducing the rate of transpiration.

iii) humidity:the more the humidity in the atmosphere the less the rate of transpiration. this is due to low diffusion gradient due to accumulation of water vapour on the surface of the leaf

iv) temperature:a rise in temp increases the water vapour holding capacity of air in the air spaces within the spongy mesophyll layer. the water vapor pressure in the intercellular spaces increases causing an increase in diffusion gradient between the intercellular spaces and the environment there4 increasing the rate of transpiration. decrease in temp decreases the water vapor holding capacity in the intercellular spaces there4 diffusion gradient is lowered there4 reducing the rate of transpiration.

Your risk of becoming obese increases by at least one-third if your partner, spouse, sibling, or close friend is obese. Your ris
svlad2 [7]

Answer:

The correct answer is: True.

Explanation:

  • Obesity is a disease condition in which the BMI or Basal Metabolic Index of a person goes beyond normal.
  • The BMI of a person is calculated by finding the ratio between the weight of the person measured in kilograms and the square of the height of the person  measured in metres.
  • A person having a BMI below 18 is considered to be underweight, between 18 and 25 is normal weight, between 25 and 30 in overweight and above 30 is obese.
  • The disease is caused more due to social reasons than biological reasons.
  • When a person A lives near the vicinity of another person B who is obese, this means the person A lives in an environment where a proper balanced diet is not maintained during the consumption of food. They tend to consume food rich in oil and fat.
  • Hence, the intake of the fat rich food by the person A will result him in consuming fat and oil in amounts far more than his body actually requires. Excess fats deposits in the body thereby increasing his BMI and resulting into obesity.
  • Due to obesity the person B will also show the symptom of being lethargic and will not  prefer to do exercises. This lethargy would be induced in person A as well.
