Cells from a developing embryo are transferred from position a to position

Cells from a developing embryo are transferred from position a to position b. ordinarily, cells from position a develop into heart muscle, and those from position b develop into skeletal muscle. the transferred cells develop into skeletal muscle. based on these results, one can conclude that

I believe that the conclusion would be the fate of the transferred cells had not been determined before they were transferred. During the course of embryonic development, mesenchymal progenitor cells originating from the somites, undergo a multistep differentiation process to form muscle fibers and muscle mass. Each somitic area contributes to the formation of the muscles. Muscles are attached to specific bones by tendons.

Question
Production of urine to modify plasma makeup is the result of ________. a. filtration b. absorption c. secretion d. filtration, absorption, and secretion
Solution 1
The production of urine to modify plasma makeup is the result of glomerular filtration, tubular absorption, and secretion. Glomerular filtration is the first step of making urine; a process where the kidney filter excess fluid and water products out of the blood in the urine collecting tubules of the kidney, to be eliminated in the body. Tubular reabsorption involves the removal of water and solutes from the tubular fluid which is returned to the circulating blood; while secretion involves the removal of wastes from the body into the bladder, then out through the urethra. 
Question
When alzheimer disease appears in middle age rather than old age, it: a. progresses more slowly. b. progresses more rapidly. c. causes death within a year. d. is benign?
Solution 1
When alzheimer disease appears in middle age rather than old age; it progresses more rapidly. Alzheimer's disease that results from the brain cell death. It is a neurodegenerative disease; such that there is progressive brain cell death that happens over a period of time. The brain tissue gets fewer and fewer nerve cells and connections. 
Question
The rabies virus is most commonly transferred through what?
Solution 1

Saliva

Rabies virus is an infectious virus which causes rabies in human and animals. Rabies is transmitted mostly through the saliva of infected animals such as birds and bats. Transmission of the virus through the human saliva is rare. Signs and symptoms of rabies virus include fever, headache, partial paralysis, and vomiting.

Solution 1

Left Hemisphere of the cerebrum

The brain (cerebrum) is composed of the left and right cerebral hemispheres which are separated by a fissure and joined by a large bundle of nerve fibers known as corpus callosum. The left hemisphere of the cerebrum is the logical side of the brain and it is responsible for the control of the right side of the body while the left side of the body is controlled by the right cerebral hemisphere.






Question
Anabolism includes reactions in which ________. a. ketone bodies are formed b. structural proteins are used as a potential energy source c. larger molecules or structures are built from smaller ones d. carbohydrate utilization increases
Solution 1
Anabolism includes reactions in which larger molecules or structures are built from smaller ones, for example the synthesis of glucose. Catabolism on the other hand describes processes that breaks down complex structures into simple ones. Examples of catabolic processes include glycolysis and the citric acid cycle among others.

Option d is correct here
Question
The brain communicates with the rest of your body by _____.
Solution 1
The Central Nervous System is the "highway" in the body through which the brain transmits electrical pulses down the spinal chord to the nerves and organs. The brain sends and transmits these signals to control the functions of the body.Hope this helps. Let me know if you need additional help!
Solution 2
The question says, how does the brain communicate with the rest of the body. The brain communicate with the other parts of the body by sending nerve impulse, which are form of electrical signal which travel throughout the body, carrying messages from the brain to the receptors and the cells of the body which respond appropriately to the signals.
Question
Much evidence indicates that _______ are a sister taxon to plants. select one or more: a. mosses b. liverworts c. red algae d. charophytes e. chlorophytes
Solution 1
Much evidence indicates that charophytes are a sister taxon to plants. Similar to green algae and land plants, charophytes have grass green chloroplast meaning they can undertake the process of photosynthesis. All members of this group form macroscopic branching filaments, and share similar type of structure. Additionally, charophytes can reproduce asexually or sexually; sexual reproduction is the main method while asexual reproduction occurs by fragmentation.

Question
How is the function of dialysis tubing similar to the small intestine?
Solution 1
I think that both the dialysis tubing and the small intestine are selectively permeable. Which means they allow only some and not all materials to pass through; for example; glucose which is a simple molecular sugar; will pass through, however larger molecules such as starch can not pass through. A dialysis tube is a semipermeable membrane that allows molecules of certain size to get in or out, while keeping molecules above that size in. They are often used to remove impurities from preparations of proteins or other macromolecules and also to normalize pH of a preparation. 
Question
Cytochrome c can be reduced directly by small molecules such as ascorbate (vitamin c). if ascorbate is added to an oxygenated solution containing purified cytochrome c and cytochrome oxidase, what would you predict would occur? a.atp synthesis would occur.
Solution 1
I think what would occur is that Oxygen would be reduced to water.  Cytochrome c is a large water soluble transmembrane protein complex found in bacteria and the mitochondrion of eukaryotes. It is a key player in the ATP synthesis in the mitochondria. In the electron transport it transfers electrons between complex II and complex IV.
