The difference in concentration on the two sides of a membrane is called what

1 answer:

7 0

When the concentration o molecules inside a cell is different form the concentration of molecules outside a cell, we can either call it hypertonic or a hypotonic solution, and the difference between the two concentrations is called a concentration gradient.

Hypertonic - name given to a solution that has a bigger concentration than the concentration in a cell.

Hypotonic - name give nto a solution that has a smaller concentration than the concentration in a cell.

Hope it helped,

Child 2 is polydactylous, otherwise normal; Child 4 has cystic fibrosis and is polydactylous.What is the genotype of the mother?

satela [25.4K]

Answer:

PpCc; ccpp; ccPp; 1/2

Explanation: The complete correct question is as follows

A polydactylous woman, otherwise normal, marries a healthy normal man. Their four children have the following phenotypes:

Child 1 is normal in all respects; Child 3 has cystic fibrosis, otherwise normal Child 2 is polydactylous, otherwise normal; Child 4 has cystic fibrosis and is polydactylous. A. What is the genotype of the mother? B. What is the genotype of child 3? C. What is the genotype of child 4? D. What is the chance that child 1 is heterozygous for cystic fibrosis?

We represent the traits of the parents with the following

P= Polydactyly

p=normal

C= normal

c= abnormal (cystic fibrosis

A. What is the genotype of the mother

Mother PpCc (polydactylous)

Father: ppCc (healthy normal)

B. What is the genotype of child 3?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child 3 will be ccpp (abnormal with cystic fibrosis)

C. What is the genotype of child 4?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child 4 will be ccPp

D. What is the chance that child 1 is heterozygous for cystic fibrosis?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child will be Cccc

The chance is 1/2

<h2>Flagging pathway EGFR development </h2>

Explanation:

The epidermal development factor (EGF) receptor (EGFR) is a receptor tyrosine kinase associated with the guideline of cell development, wound mending, and tissue fix. When EGF ties to the EGFR, a course of downstream occasions makes the cell develop and isolate. In the event that EGFR is actuated at improper occasions, uncontrolled cell development (malignancy) may happen.
After the ligand ties to the phone surface receptor, the initiation of the receptor's intracellular parts sets off a chain of occasions that is known as a flagging pathway, here and there called a flagging course. In a flagging pathway, second delivery people catalysts and enacted proteins interface with explicit proteins, which are thus initiated in a chain response that in the long run prompts an adjustment in the cell's condition
For example, an expansion in digestion or explicit quality articulation. The occasions in the course happen in an arrangement, much like an ebb and flow streams in a waterway. Collaborations that happen before a specific point are characterized as upstream occasions, and occasions after that point are called downstream occasions.
