Answer:
Thus, 50% of the population are are heterozygous carriers for this condition
Explanation:
Researchers have calculated that 22% of the population have Uner Tan Syndrome. This condition follows the recessive mode of inheritance.
22% have the condition = q² (genotypic frequency uu) = 22/100 = 0.22
using the formular p + q = 1, since q² = 0.22, q = √0.22 = 0.4690
Thus p = 1-q where is 0.4690 = 1-0.4690
p = 0.5310
Then p² = 0.5310² = 0.2820 = 28% (genotypic frequency of homozygous normal)
using the formula p² + 2pq + q² where 2pq is the genotypic frequency of the heterozygous carriers. Thus, we have
2 x 0.5310 x 0.4690 = 0.498 = 50%
Thus, 50% of the population are are heterozygous carriers for this condition
Answer: A. Water must be available for plants to transpire and the air cannot be saturated with humidity.
Explanation:
Evapotranspiration is the sum of evaporation and transpiration. Evaporation is the loss of water from the earth surface or ground water table and transpiration is lost of water from plant surfaces. Plant absorps water from the soil through the root and it is transport by xylem to various body cells.
When the humidity is high and the air is saturated with water the rate of evapotranspiration is low but at a low humidity the rate of evaporation is high until the air is saturated.
Temperature also have a major role in transpiration. When the temperature is high the plant stomata is open which favours water Loss from plant but when the temperature is low plant closes their stomata in response to temperature change.
Answer:
Ecology is the study of environment and biology is study of plant and animals.The interrelationship between an organism and environment
Explanation:
Ecology is the study of organisms, its distribution, abundance,interrelationship with another organism and the interaction of organisms with their environment in which they adapt to survive.
Sunlight is the main source of energy for living beings on earth. Movement of energy flow and nutrient cycle plays a significant role in living beings.
In ecology there are different levels of organization such as species, population community,ecosystem,biome and biosphere.
There are different cycles which an organism required to survive, carbon cycle, nitrogen cycle, oxygen cycle, phosphorous cycle, and of course the most basic thing to survive is the water cycle. All these cycles coming under one term called the biogeochemical cycle.
The ecological pyramids such as pyramids of an ecosystem, pyramids of number pyramids of energy flow and pyramids of biomass based on these pyramids living things survive.
