Photosynthesis ceases when leaves wilt, mainly because the chlorophyll in wilting leaves is degraded.

claiming that chlorophyll usually deteriorates. Thus, photosynthesis or leaf growth inside the building will stop. Thus, it will end.

Thus, photosynthesis or leaf growth in the building will cease.

  • The plant starts to wilt as the dehydrated collapsing cells in the leaves and stems can no longer stand upright. The drooping leaves expose less surface area to the sun's evaporative rays, which is an interesting way that wilting also helps to prevent water loss.
  • When roots are unable to adequately hydrate the stems and leaves, plants wilt. Plants are not harmed by wilting when it lasts only a short while. On hot days, a plant may begin to wilt because the moisture is leaving the leaves faster than the roots can absorb it.

miss Akunina [59]

Answer:

a) The genotype of her father = "aa".

The genotype of her mother = "Aa".

The genotype of Sally is "Aa".  

b) 1/2

c) 1/2

Explanation:

a) Sally's father has alkaptonuria. So, the genotype of her father is "aa". Her mother is normal. Since her brother is affected by the disease, he should be homozygous recessive (aa). This means that the mother also has one copy of "a" allele and is heterozygous dominant (Aa). A cross between Aa (mother) and aa (father) would give 50% affected progeny with "Aa" genotype. So, the genotype of Sally is "Aa".  

b) The genotype of her mother= Aa

The genotype of her father = aa

Aa x aa = 1/2 Aa (affected): 1/2 aa (normal)

So, if Sally's parents have another child, there is a 1/2 probability that this child will have alkaptonuria.  

c) The genotype of Sally = Aa

Genotype of the man Sally marries= aa (since he is affected with alkaptonuria)

Aa x aa= 1/2 Aa (affected): 1/2 aa (normal)

There is a 1/2 probability that their child will have alkaptonuria.

How does the greenhouse effect trap heat?
galben [10]

Answer:: Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it. ... They radiate the heat back to the Earth's surface, to another greenhouse gas molecule, or out to space.
