How has artificial selection demonstrated species changing over time

Biology
1 answer:
tatyana61 [14]3 years ago
8 0

Answer:

Long before Darwin and Wallace, farmers and breeders were using the idea of selection to cause major changes in the features of their plants and animals over the course of decades. Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.

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.

what would you be most likely to measure by immersing an object in water and seeing how much the water level rises?
Rina8888 [55]
<span>The volume of an irregular solid object would be measured in such a way. It is actually how the story of Archimedes goes when he managed to measure whether or not there's the right amount of gold in a king's crown using the same method.</span>
