Golf courses make use of fertilizers to keep the grass green and healthy. Using your knowledge of osmosis, explain how applying
Nostrana [21]
Osmosis is the diffusion of water. Water tends to diffuse to the area with a higher concentration of solute. (Particles) In this case, Im assuming the fertilizer is the solute because it contains chemicals. Therefore, since water tends to diffuse to higher concentration of solute, the water in the grass will diffuse out to dilute the fertilizer on the surface of the grass. Without water, the grass will be dehydrated and shrivel up and die. Hopefully you find my answer helpful!

What are the two different results of a lack of calcium and a lack of atp?
liq [111]
<span>There are numerous proteins in muscle. The main two are thin actin filaments and thick myosin filaments. Thin filaments form a scaffold that thick filaments crawl up. There are many regulatory proteins such as troponin I, troponin C, and tropomyosin. There are also proteins that stabilize the cells and anchor the filaments to other cellular structures. A prime example of this is dystrophin. This protein is thought to stabilize the cell membrane during contraction and prevent it from breaking. Those who lack completely lack dystrophin have a disorder known as Duchene muscular dystrophy. This disease is characterized by muscle wasting begininng in at a young age and usually results in death by the mid 20s. The sarcomere is the repeating unit of skeletal muscle. 

Muscle cells contract by interactions of myosin heads on thick filament with actin monomers on thin filament. The myosin heads bind tightly to actin monomers until ATP binds to the myosin. This causes the release of the myosin head, which subsequently swings foward and associates with an actin monomer further up the thin filament. Hydrolysis and of ATP and the release of ADP and a phosphate allows the mysosin head to pull the thick filament up the thin filament. There are roughly 500 myosin heads on each thick filament and when they repeatedly move up the thin filament, the muscle contracts. There are many regulatory proteins of this contraction. For example, troponin I, troponin C, and tropomyosin form a regulatory switch that blocks myosin heads from binding to actin monomers until a nerve impulse stimulates an influx of calcium. This causes the switch to allow the myosin to bind to the actin and allows the muscle to contract. </span><span>

The Hopi, Zuni, and other Southwest indigenous peopleshave a relatively high frequency of albinism resulting from homozygosity f
Ket [755]

Answer:

a. Zero percent

b. Fifty percent

Explanation:

As it has been mentioned in the question that both man and woman are normally pigmented and each one have an albino parent thus both will be heterozygous and their allelic makeup will be as follows -

Man - Aa

Woman - Aa

After a cross between Aa × Aa we get the following result-

One AA, Two Aa and One aa

It is clear that only the aa type of offsprings will be albino.

Out of 4 there is probability of only one to be albino so out of two there will be 50% probability of being albino.

The probability of both sons to be albino will be zero percent.

If a woman is homozygous for red hair and her husband is homozygous for brown hair, what is the probability that they will have
boyakko [2]
Well, you failed to mention which one is the recessive trait in this instance. But, let’s say red hair is recessive, denoted by r and brown hair is dominant denoted by R. Mom is rr and dad is RR. All children are going to be Rr and so heterozygous. They will all carry the trait for red hair but will express brown hair themselves, so 0% probability of having a child with red hair from the initial parents
