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.

Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of __________.
Anettt [7]

Option (B) Habituation is the right answer.

Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of habituation.

<h3>Crocodile and avian mutualism—is it real?</h3>
  • One of nature's best instances of mutualism is the interaction between a Nile crocodile and an Egyptian plover bird.
  • A crocodile will simply open his mouth and wait when he needs to floss.
  • The plover bird will involuntarily swoop down and grab meat scraps from the crocodile's gaping jaws.

<h3>Why do crocodiles develop a habit of approaching the birds that brush their teeth?</h3>
  • It is a phenomenon of evolution that when a bird used to sit in a crocodile's mouth, the crocodile didn't eat it; instead, the crocodile used to allow the bird to sit in the mouth and clean the crocodile's teeth so that they can live longer, whereas the birds could get the free food from the crocodile's mouth.
  • It is an illustration of how the two are mutually beneficial.
  • The same is true now because crocodiles have adapted to the fact that birds will clean their teeth, so rather than consuming them, they ignore the birds.
