Diffusion can be defined as active transport of particles up a concentration gradient.

movement through a cell membrane using energy from ATP

movement of particles from a region of high concentration to a reaigon of low conentration

movement of particles from a region of low concentration to a regoin or to a high region

Answers

Answer 1

Answer:

Answer:

Option (3).

Explanation:

The molecules may transport from inside and outside of the cell from their region of low concentration to high concentration or vice-versa. Different types of transport process are diffusion, osmosis, primary active transport.

Diffusion occurs naturally in the organism and no energy is required for its transport. The molecules move to the region of lower concentration from its region of higher concentration. The molecules moves along the concentration gradient.

Thus, the correct answer is option (3).

Answer 2

Answer: movement of particles from a region of a high concentration to a region of low concentration

Why energy is needed for active transport

Answers

Active transports is actively done to remove or add something that would not normally move there in comparison to passive which occurs on its own without the need for energy

Hemophilia is an X-linked recessive disorder (Xh) that is passed through generations and can be traced by using a pedigree. What is the probability that a female child of Charles and Marie would suffer from hemophilia?a. 0 percent
b. 25 percent
c. 50 percent
d. 100 percent

Answers

Since hemophilia is an X-linked recessive disorder, the probability depends on the X alleles.
So, if father has dominant allele (H), the probability that a female child would suffer from hemophilia (genotype: hh) is 0%, no matter of mother's genotype:

Father Mother
Parents: H x Hh
Daughter: HH or Hh

Father Mother
Parents: H x HH
Daughter: HH

Father Mother
Parents: H x hh
Daughter: Hh or Hh

But, if the father has recessive allele, the probability that a female child would suffer from hemophilia (genotype: hh) will depend on mother's genotype.
If mother is dominant homozygous, there will be 0% of possibility:
Father Mother
Parents: h x HH
Daughter: Hh

If mother is recessive homozygous, the possibility is 100%:
Father Mother
Parents: h x hh
Daughter: hh

If mother is heterozygous, the possibility is 50%:
Father Mother
Parents: h x Hh
Daughter: Hh or hh

Answer:

It's 0%

Explanation:

It's 0%
