Answer:
1/2
Explanation:
Let's assume that the allele "p" is responsible for PKU in the homozygous state. According to the given information, both the parents are unaffected by the disorder but have an affected child. This means that both the parents carry at least one copy of the recessive allele responsible for the disease. Therefore, the genotype of each of the parents is Pp. A cross between Pp and Pp would produce progeny in following ratio=
Pp x Pp = 1/4 PP: 1/2/ Pp: 1/4 pp
Therefore, the probability that their next child will carry just one recessive allele is 1/2.
Effacement: The cervix – which is normally long and thick, measuring about 1-2 inches, starts to get shorter and thinner. This process is known as effacement. As the cervix gets more and more effaced, it gets shorter and shorter and “pulled up” into the lower part of the uterus.
Dilation: At the same time, the cervix softens and begins to open up – known as dilation. This widening, allows a smooth passage for the baby’s head and the rest of the body from the uterus into the vaginal canal.

Answer:
All the above keywords conclude a process used by plant which is known as photosynthesis. This process is done by all the green plants in the presence of sunlight and also in dark.
Explanation:
Photosynthesis is defined as the process by which all the green plants prepare their food in the presence of sunlight by the use of water, minerals and carbon dioxide. Chloroplast provides green color to the plant and it is also known as photosynthesis site. Glucose is the product and oxygen is a byproduct of photosynthesis.
Calvin cycle is a type of photosynthesis that is also followed by some. the energy released is counted in the terms of ATP which is also known as adenosine triphosphate. Sunlight plays a role of catalyst in the formation of food by the process of photosynthesis
