How is a gill adapted for gas exchange?
Answer:
The exchange surfaces in fish are gills . Exchange of gases in fish is very efficient because of: the large surface area of the blood capillaries in each gill filament. the short distance required for diffusion – the outer layer of the gill filaments and the capillary walls are just one cell thick.Explanation:

The experiment I thought of is the brownian motion. (this experiment refers to water particles)
In 1827, a botanist named Robert Brown observed pollen grains that moved randomly when in water. At the time, he just didn't know how to explain why the grains moved randomy and not in a particular direction.
Later in 1905, Albert Einstein explained that the grains moved randomly due to individual water molecules colliding with the pollen grains. This provided evidence that molecules did exist and contributed to the particle theory.
(Particle theory is a theory that explains properties of solids metals and gases. It also involves the arrangement and movement of particles, which can help with studying movement of air particles)

Select all the factors that you know from the material presented in this lesson that are true of sickle cell anemia. It is an example of a single-gene disorder. It occurs in both males and females. Its gene is found on the X chromosome. It is passed down from both parents. It interferes with proper breathing and digestion. It involves the red blood cells. It is sometimes treated with blood transfusions.
Answer:
a
b
d
f
g
Explanation:
Sickle cell anemia is a condition that deals with the genetic disorders in which valine replaces glutamate at 6th position. it is transmitted through father. all the options are correct except its passing from both parents.
What happens in sickle cell anemia ?It is a genetic disorder in which normal RBC structures gets distorted and it gets the shape of sickle thus called sickle cell anemia. The distorted RBC are unable to carry oxygen in themselves.
It is found on the X chromosomes and the male is a carrier if the XY genotype of the male carries the X chromosome that is malfunctioned then it leads to the condition in the offspring.
Thus, sickle cell anemia can be treated as well via the blood transfusions.

Passive transport is the movement of molecules across a membrane without the use of energy. Why causes the molecules to move?
Molecules move inside a cell to interact with organelles.
Molecules move across a membrane to reach other cells.
Molecules move from an area of relatively low concentration to an area of higher concentration.
Molecules move from an area of relatively high concentration to an area of lower concentration.
PLEASE ANSWER RIGHT!!!!!
Answer:
Explanation:
The energy driving the movement of molecules during passive transport comes from differences in the concentration of the molecules on either side of the membrane with the molecules tending to move from the side of higher concentration to the side of lower concentration because of their net thermal movement.
Because there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done
How is energy used to move?
Molecules do not stop moving once they reach equilibrium. Passive Transport (no energy needed). The movement of particles from an area of high concentration to low concentration. Particles pass right through the cell membrane. the (passive) movement of large particles or substances across the cell membrane through protein channels.

Could there be a frameshift mutation that would not affect the
structure and function of the resulting protein? Explain your
answer.
Answer:
no, because it would have to be a perfect process, and changing would end in a mistake.
Explanation:
(detail) It would be unlikely, because a frameshift mutation shifts every nucleotide down one, so several amino acids in the protein are likely to be changed. However, if a frameshift mutation occurred near the end of the DNA sequence, the protein could have minimal changes to its structure and function.
It is possible the emergence of a frameshift mutation that does not affect the structure of a protein, but it will invariably modify its structure.
What is a mutation?A mutation is any alteration in the genetic material (DNA) that forms the genome of an organism.
A frameshift mutation can be defined as a mutation that modifies the Open reading Frame of a given gene.A frameshift mutation can be caused by deletions or insertions (indels) in the resulting DNA nucleotide sequence.In conclusion, it is possible the emergence of a frameshift mutation that does not affect the structure of a protein, but it will invariably modify its structure.
