So the flowchart should go like this:
Mutation in the CFTR gene >>>>>> Production of defective CFTR protein >>>>>> defective CFTR protein in cell membrane or no protein at all >>>>>>> Impaired ion transport across the cells >>>>>>> Cells secrete less chloride >>>>>>> leads to more re-absorption of sodium and water into the cells >>>>>>> decreased hydration of mucus present outside the cells as more water is absorbed into the cells >>>>>>>> thick viscous mucus.
Answer:
The endocrine system, made up of all the body's different hormones, regulates all biological processes in the body from conception through adulthood and into old age, including the development of the brain and nervous system, the growth and function of the reproductive system, as well as the metabolism and blood sugar
Explanation:
The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )
The phenotype of the cross is 3 : 1 ( Tall : Dwarf )
<u>Explanation:</u>
Given:
Cross between two heterozygous tall pea plant
Let the allele of a tall pea plant be represented by T and for dwarf be t
In heterozygous condition, the genotype would be Tt
Cross between Tt X Tt is shown in the diagram inserted.
According to the cross performed:
The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )
The phenotype of the cross is 3 : 1 ( Tall : Dwarf )
Answer:
bones,muscles, and tendons
Explanation:
Which statement is true for some photosynthesizing animals?
A.Some carry out photosynthesis through the chloroplasts they incorporate into their cells.
B.They conduct light-dependent reactions and the Calvin cycle in the mitochondria.
(C.They’re true autotrophs because they can photosynthesize on their own.)
D.They’re single-celled organisms that move like animals, but they contain chloroplasts.
