Answer:

after Clark was treated with a hypertonic solution? increased Na concentration in matrix of brain caused water from blood to move in to the brain which increased the matrix pressure. Pressure caused the neuron firing rate to increase which increased the likelihood of seizures.

Explanation:

hope this helps :)

A researcher is interested in finding out if the amount of amylase, a digestive enzyme found in saliva responsible for digesting

kogti [31]

The answer is Take consistent amounts of saliva samples from a number of people who have not eaten in 8 hours and measure the quantity of amylase in each sample.

First, the researcher needs to know the quantity of amylase in the same amount of saliva. Thus the amount must be consistent and not varying.
Next, people must not eat in 8 hours, so they are all in the same condition at the moment of collecting saliva. If some eat immediately before the sample collecting while some eat 8 hours before, the content of their saliva will be different.
For the correct results, all conditions must be the same.

Answer:

In a general aspect, humid and warm air moves to lower latitudes or in altitude, losing heat and getting colder. Its humidity condenses and causes precipitation. Depending on the air movement there are different kinds of rain.

Explanation:

At a global level, it occurs unequal warming of the atmosphere, which depends on many factors and varies with latitude. This occurs because solar radiation reaches the earth differently at different latitudes, resulting in big convective cells of atmospheric circulation: Hardley cell, Ferrel cell, and Polar cell.

A convective cell is the movement of the humid air among different latitudes. Air moves from higher latitudes to lower latitudes, getting warm, getting less dense, and ascending. As the air gets higher in altitude, it´s density and pressure decrease, so the air tends to expand with elevation in response to the reduced pressure. Gases in expansion experiment adiabatic cooling, losing caloric energy as their molecules move getting farther away from each other. As the air gets higher, it gets colder, and hence, denser. The result is that descends again. Humidity gets denser and precipitates.

• Rain is controlled by temperature on the earth´s surface, atmospheric global air circulation, the position of the mountains and oceans, closure to the oceans.

• There are different kinds of precipitations according to their origin.

i. Convective precipitation: These are the most typical ones. Air gets warmer and less dense, elevating in altitude with humidity. On the way, it starts to get colder, and the humidity condenses, resulting in precipitation. Depending o the degree of condensation, the precipitation might be in a liquid state (rain), semisolid-state (snow), or solid-state (hail).

ii. Frontal Precipitations: They occur when a polar front coming from higher latitudes collide with a warm front coming from lower latitudes, resulting in a strong rain. This is typical of grasslands or temperate forests (approximately 40 º latitude)

iii. Orographic Precipitations: They occur when humid wind ascends by a mountain range, causing its adiabatic cooling, condensing the humidity, and precipitating.

natta225 [31]

Variable is the object where the observation will either influence or receive the effect from the other object or variable. Hence, variables divided into two distinct parts in a study or traditionally an experimental study which is the independent variable and the dependent variable. The independent variable is the variable that can stand for itself until it affects the dependent variable, which is the variable that was influenced by the independent variable.

IV: Gender of the alligator
DV: Temperature at which the alligator mother will need to supply.

A population of horses has individuals that are either gray or chestnut colored. The gray color allele, G, is dominant over the

Dahasolnce [82]

We solve the problem using the Hardy-Wineberg equation.

We have the frequency for gray trait as p = = 0.8

∴ p² = 0.64

64 % of the horses are homozygous for the gray trait.

Solving for the frequency of white chestnut trait by using the fact that,

p + q = 1

∴ q = 1 - p = 1 - 0.8 = 0.2

Now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous gray trait,

∴ 2pq = 2 x 0.8 x 0.2 = 0.32

Therefore, in a population of 100 horses, 32% are heterozygous for gray trait.

Hence the total number of gray horses in a population of 100 will be,

32 (heterozygous gray horses) + 64 (homozygous gray horses) = 96 (gray horses)

Hence, 96% of the horses are gray in color.

Other birds of prey produce pellets as well, and the contents are dictated by where the bird lives. 1. What would you expect to

a_sh-v [17]

Answer:

crab shells, fish scales, and fish bones might be found. And pieces of trash like chip paper, rubber bands, and tin foil.

Explanation:

Pellet can be described as a compressed mass of a substance, which is usually have round shape and small size.

it is understood that the pellet is formed when the birds catches the prey and swallow it in large chunks . Then, they digest the parts of the prey that are digestible, which goes down their esophagus, then through their proventriculus , and finally into the gizzard. The parts that are not digestible form a pellet.

It should be noted that the pellet is stored for several hours, after which it is regurgitated.
