Explain how diffusion restored homeostasis during the dialysis treatment
Answer:
If the patient's blood is too low in ions, they will diffuse from the dialysis fluid into the blood, restoring the ideal level in the blood. If the patient's blood is too high in ions, the excess ions will diffuse from the blood to the dialysis fluid.
Explanation:
I may be wrong but yeh
If the patient's blood is too low in ions, they will diffuse from the dialysis fluid into the blood, restoring the ideal level in the blood. If the patient's blood is too high in ions, the excess ions will diffuse from the blood to the dialysis fluid.
What do you mean by dialysis?Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned.
Moreover, hemodialysis is most often done at a special dialysis center. You will have about 3 treatments a week. Treatment takes about 3 to 4 hours each time.
In hemodialysis, the wastes and excess water are removed by using an external filter called a dialyzer, which contains a semipermeable membrane.

compare and contrast the rock cycle and the carbon cycle
Answer:
The rock cycle and water cycle overlap with erosion, transporting, and deposition.carbon atoms are used repeatedly on Earth and cycled between the atmosphere, hydrosphere, biosphere, and lithosphere through processes
Explanation:
The rock cycle and the carbon cycle are two different types of natural cycles that occur on earth. The difference include components, processes, time scale, human impact, and environmental implications.
What is the difference between rock cycle and carbon cycle?The rock cycle is a continuous process that occurs over millions of years, during which rocks are transformed from one type to another. There are three major types of rocks: igneous, sedimentary, and metamorphic. Each type of rock is formed through a different process.
The carbon cycle is the process by which carbon is cycled between the atmosphere, oceans, and living organisms. Carbon is essential for life, and is found in all living organisms. The carbon cycle is driven by photosynthesis, respiration, and decomposition.
During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it to build organic molecules. These organic molecules are then consumed by other organisms, and carbon is transferred up the food chain.
When organisms die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide back into the atmosphere.
In addition, carbon is stored in fossil fuels such as coal, oil, and natural gas, which are formed from the remains of ancient plants and animals. When these fuels are burned, carbon is released into the atmosphere, contributing to global warming.

What is cell cycle?Cell cycle has been as the defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one has G1 phase in which the size of the cell increases, S phase synthesis of DNA takes place and the third step has G2 phase in which all cell ready to divide.
Cell has been defined as the base of the life as it has the structural as well as functional unit of life. Cell has been made up of pre existing cells and the cell contain various part cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Describe what happens during interphase. Be sure to include all three parts of interphase.
Answer:
Interphase is divided into three subphases which are G1 phase, S phase and G2 phase.
Explanation:
During G1 and G2 phases, the cell grows by producing proteins and cytoplasmic organelles. Cell growth and cell differentiation occur. In the S phase, synthesis of DNA occurs. The chromosomes are duplicated and DNA has replicated to form two identical sister chromatids joined together by centromere. During interphase, the chromosomes are not visible but appear as thread-like structures, chromatin. In general. Interphase is the phase where the cell prepares for cell division. It involves synthesis of protein and organelles, growth, replication of DNA, cell differentiation and energy storage.

A couple has three children, two without sickle cell anemia and one with sickle cell anemia. The mother has sickle cell anemia as well, while the father does not.
Make and defend a claim as to how this couple could have children with and without sickle cell anemia.
Answer:
Explanation:
The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.
Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.
Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.
Assuming the genotype of the father is AA:
SS x AA
AS AS AS AS
All the children would be normal in this case.
Assuming that the genotype of the father is AS
SS x AS
AS SS AS SS
50% of the children would have sickle cell while the remaining 50% would be normal.
Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.

because Chromatin is a substance within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions. The major proteins in chromatin are histones, which Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Chromatin consists of complexes of small proteins known as histones and DNA. hope this helps have a nice day ❤️❤️❤️
