Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.

Biology

Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

classify if the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominan
Verizon [17]
C = dominant
c = recessive (cystic fibrosis)
CC, cc = homozygous (homo = same)
Cc = heterozygous (hetero = different)

Recessive traits are expressed only when two recessive alleles are present

If you get CC, you will not have cystic fibrosis. (<span>c </span>is the cystic fibrosis allele)
This person would be homozygous dominant and would not pass on the disease because they do not have any cystic fibrosis alleles.

If you get<span> Cc</span> you will not have cystic fibrosis b/c the<span> C</span> is dominant and overrides the cystic fibrosis allele c.
This person would be heterozygous and, though they do not have the disease, they would still have a chance of passing on the disease because they carry the cystic fibrosis allele.

If you get cc you will have cystic fibrosis b/c c is the cystic fibrosis allele and it is not being overridden by a dominant allele.
This person would be homozygous recessive.

A course of action to restore growth in the stunned plants what should be done?
Otrada [13]
Add some sugar – Believe or not, studies have shown that a weak sugar and water solution made with plain sugar from the grocery store given to a plant after transplanting can help recovery time for transplant shock in plants. It can also be used as a transplant shock preventer if applied at the time of transplanting. It only helps with some plants but, as this will not harm the plant, it is worth a try. Trim back the plant – Trimming back the plant allows the plant to focus on regrowing its roots. In perennials, trim back about one-third of the plant. In annuals, if the plant is a bush type, trim back one-third of the plant. If it is a plant with a main stem, cut off half of each leaf. Keep roots moist – Keep the soil well watered, but make sure that the plant has good drainage and is not in standing water.


Wait patiently – Sometimes a plant just needs a few days to recover from transplant shock. Give it some time and care for it as you normally would and it may come back on its own. Now that you know a little more about how to avoid transplant shock and how to hopefully cure plant transplant shock, you know with a little plant preparation, preventing shock should be an easier task.
