Transpiration is the process where water evaporates from the pores of
leaves. Because of the charges of water molecules (I don't know the
specifics), the evaporation of water molecules leads to others being
pulled up the xylem tubes towards the leaves - hence transpiration is a
necessary evil because it involves constant water loss, but is also
useful for providing water for photosynthesis, support of cells by
osmotic intake of water and cooling for optimum enzymatic efficiency.
Therefore as transpiration increases (which will be if temperature is high to cause more evaporation, windspeed is high to carry water vapour away and humidity is low so diffusion of vapour away from the leaf is more favourable), the intake of water will also increase because it is literally pulled up the xylem tubes from the roots to the leaves.
That's how I understand it anyway :)
I hope this helps
Answer;
The above statement is true
One type of personal health monitor measures the amount of time you spend in REM sleep.
Explanation;
-Fitness tracker or monitors have the ability to monitor or track the shut-eye during sleep.
-These trackers all continuously monitor the movements of the eye during sleep and also assess sleep-wake cycles to ascertain whether an individual is in deep or light sleep.
-Some of the trackers incorporates heart rate data to get a better sense of how deep one is into their sleep.
It is only one...................
The correct answer is option B. Genotype AA, phenotype-Unaffected.
The cystic fibrosis is a condition caused by the inheritance of the two recessive allele, It is an autosomal recessive disease.
In the given case, the parents are carriers, and the carriers are always heterozygotes. Hence, the phenotype of the both parent should be Aa. A possible cross of the parents is shown in the figure below.
In case, the progeny have a single dominant trait, the child would not be affected, but will be a carrier and can pass the disease to offspring. In case, the child inherit both the dominant allele (homozygous dominant) from the parents, then he/she would be unaffected. In case, the phenotype of the child is homozygous recessive then it would be affected.
