Answer:
The red blood cells could burst.
Explanation:
If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.
This will result in the red blood cells becoming swollen and even potential bursting.
Answer:
XnY
Explanation:
II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.
Answer:
The first law of Thermodynamics
Explanation: The law states that energy can never be destroyed, or created. This is because of a cycle of atoms, atoms are always changing, never getting destroyed.
Hairs are tiny shafts of a protein called keratin. They are anchored in a group of specialised cells called hair follicles, which supply oxygen and nutrients to the root (or bulb) of the hair, and lubricate the hair with an oily substance called sebum.
The human body is completely covered with hair follicles, except on the palms of the hands, soles of the feet and the lips. Mostly, hair follicles are tiny, and the hairs they produce don't grow long enough to protrude from the pore.
The areas where hairs do protrude (and are visible above the skin) include the armpits, face, around the genitals, the front of the chest, the back, and most profusely, on the scalp of the head. A scalp typically contains about 100,000 hair follicles.
Hair is in a constant cycle of growth, rest, and renewal. Hairs grow and then are shed, but because they grow at different rates they don't all shed at once.
It takes about three years for hair follicles to produce a hair that grows, rests, falls out and then regrows, which means the scalp loses between 50 and 200 hairs a day.
Answer:
The answer is A. provides the energy for adding a phosphate to ADP to make ATP.
Explanation:
The ATP synthase is an enzyme located in the inner membrane of the mitochondria. It creates a hydrophilic channel across the inner mitochondrial membrane that allows a flux of protons that moves down an electrochemical gradient. These H+ ions are then used as an energy source during the enzymatic reaction that converts ADP + Pi to ATP. This process is called chemiosmois and it’s not unique to cellular respiration, it is also used in photosynthesis and other processes involved in homeostasis. The proton-motive force, as some people refer to the proton gradient was first proposed by Peter Mitchel in the 1960’s as the chemiosmotic theory.
