The leading edge of the Arctic air mass in Figure 2 reached Texas. At 14Z, the front had just pushed through the southernmost city of Brownsville, TX where a cold front curved westward into Mexico, with bitterly cold air north (behind) of the front. (Option C).
What is Artic Air Mass?
Because the Arctic air mass is extremely cold and dry, it creates the Cold Front. Arctic air masses, are extremely frigid due to their origin in the Arctic or Antarctic regions. Polar air masses, are not as frigid as Arctic air masses since they originate at higher land and sea latitudes.
What are the traits of Artic Air Mass?An arctic maritime air mass has comparable properties to a polar maritime air mass, but the air is colder and less moist due to the shorter sea track.
Arctic air is uncommon in the summer, but when it does arrive, it can bring heavy rain or thunderstorms as well as very low temperatures.

Arrange these statements into the most appropriate order, reflecting what happens following initiation of the Valsalva maneuver:
1. Decrease in venous return lowers left ventricular stroke volume and arterial blood pressure.
2. Initial increase in left ventricular stroke volume raises systemic blood pressure.
3. Initial increase in left ventricular volume results in increase in left ventricular stroke volume. 4. Intrathoracic pressure is raised by expiring against a closed glottis.
5. Raised intrathoracic pressure decreases venous return to the right atrium from the systemic circulation.
6. Raised intrathoracic pressure initially increases venous return to the left atrium from the lungs. 7. Raised systemic blood pressure reflexively decreases heart rate.
8. This results in peripheral vasoconstriction and increasing heart rate.
Answers
1. When Valsalva maneuvre is done, then intrathoracic pressure is increased as the expiration is done forcibly against the closed glottis.
2. Raised intrathoracic pressure compresses the lungs and blood to left atrium is increased. Left atrium sends this blood to the left ventricle.
3. When blood is increased in left ventricle, it will contract more efficiently causing more stroke volume and cardiac output.
4. More cardiac output increases the systolic blood pressure.
5. Intrathoracic pressure is increased which further compresses the vena cava and venous return to right atrium is decreased.
6. Decrease in venous return means less blood will go to the left ventricle. Left preload causes less contraction and stroke volume is reduced. Cardiac output reduces.
7. To compensate for decreased cardiac output, the vessels undergo vasoconstriction and the heart rate is also increased.
8. The raised systolic blood pressure reflexively decrease the raised heart rate and heart rate becomes Normal.
Intrathoracic pressure influences venous go back and therefore cardiac output and arterial pressure. Inspiration drops intrathoracic stress, dilates the thoracic vena cava, and acutely decreases atrial filling. Cardiac output falls, and therefore arterial stress falls.
High quality-pressure air flow increases intrathoracic stress. when you consider that diaphragmatic descent will increase intra-belly strain, the decrease inside the strain gradient for venous return is much less than would in any other case occur if the only exchange have been an boom in proper atrial stress.

Answers
The unit of measurement which would be most likely used to measure the length and width of shoes and window curtains is referred to as centimeter.
What is Measurement?Measurement is commonly used and it is used to determine how big or small an object or body is and can be measured using various units depending on the parameter involved.
Measurement of the length and width of shoes and window curtains involves the use of tape rule which has standard readings for inches and centimeters and the objects involved aren't too small or too big in terms of their various sizes. Centimeter as a unit also is in the medium form which makes an easy match.
This is therefore the reason why centimeter will be most likely used so as to get more accurate readings and results and is therefore the most appropriate choice.

Describe how plants leaves are adapted for obtaining carbon dioxide for photosynthesis.
Answers
For gas exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which allow carbon dioxide to enter the leaf and oxygen to exit, they are well equipped for photosynthesis.
The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
The main purpose of photosynthesis is to transform solar energy into chemical energy, which is then stored for later use. This mechanism primarily provides energy to the planet's life systems.
The C3, C4, and CAM pathways are the three basic categories of photosynthetic pathways. They all use the Calvin cycle to convert CO2 into sugars, but each pathway does so in a somewhat different way.

Mini Case
16. Marc, a first-year college student, starts out on a
backpacking trip in southern New Mexico. It is September,
so the daytime temperatures are quite high, and the
desert air is very dry. He has a portable water filter to treat
river and stream water that he finds on his planned route
through the Gila wilderness. On the second day of his
week-long trip, Marc's water filter breaks. He is afraid of
contracting giardiasis (a protozoal disease spread through
water contaminated by animal feces), so he drinks only the
small amount of water that he can boil on his camp stove
at night. By the fifth night, Marc is feeling weak and thirsty,
and starts to hike out. He makes it to a local highway
and collapses. A passing motorist calls 911 for an
ambulance.
Apply Your Knowledge
a. Given that Marc has sweated a lot, and that sweating
causes the loss of more water than solutes, what has
happened to the solute concentration of Marc's blood
as a result of his dehydration?
b. From the solute concentration of Marc's blood, what
is likely to be happening to his body cells that are in
contact with his blood and related fluids (e.g., lymph
and cerebral spinal fluid)?
c. The paramedics have three saline solutions available.
The first is a "normal" isotonic saline solution (0.9%
NaCl), the second is a hypertonic saline solution
(3% NaCl), and the third is a "half normal" saline
solution (0.45% NaCl). Which one would you use to
treat Marc? Why?
Answers
a) Marc's blood now has a higher solute concentration than usual since he has lost more water than solutes. b) Marc's blood has a greater than usual solute concentration, which means that any cells in touch with it are probably osmotically losing water and starting to shrink.
c) Marc has to have his blood volume increased and his present solute concentration lowered (back to a normal concentration). Therefore, the "half normal" saline is most likely your best option. It will increase volume, but when mixed with his concentrated blood, its solute concentration will revert to normal because it is less concentrated than usual.
The amount of a solute per unit volume of a solution, or the concentration of a chemical species in a solution, is expressed as a solute's molar concentration. The most common unit used in chemistry to express molarity is the number of moles per liter, represented by the unit sign mol/L or mol/dm3 in SI units.
The thing that dissolves in a solution is referred to as a solute. In fluid solutions, the solvent is more prevalent than the solute. A chemical solution's concentration is a measurement of the solute content in relation to the solvent content.

Humans have an omnivorous diet. Suggest how the human digestive system is adapted
to break down the different types of food that humans eat.
Answers
Human beings are omnivores.
The term "omnivores" refers to generalized feeding i.e., they can consume both plants and meat. They have specialized adaptations for gathering, eating, and processing food that contains both plant protein and animal protein. McArdle goes on to say that omnivores are primarily "opportunistic" feeders that take advantage of food opportunities in order to survive. They exhibit more universal physiological and anatomical characteristics. One such feature is the human dentition (set of teeth). It proves that the human diet is by nature omnivorous and not herbivorous given the presence of canine teeth for tearing flesh and molars for grinding and chewing. Our digestive system is shorter than that of a herbivore and longer than that of a carnivorous animal. A characteristic of omnivores is this. Vegetation requires a longer digestive system as that of herbivores to be fully digest than plant based diet. Meat is however, easily broken down. Nevertheless, consuming animal protein is not necessary for humans. It's up to you what you do.Hence, human dentition and length of the digestive tract are examples that suggest that humans are adapted to have an omnivorous diet.

A population has the following genotype frequencies: AA = 15%, Aa = 35%, aa = 50%.
What is the frequency of the A allele?
What is the frequency of the a allele?
Answers
Remember these two equations,
[tex]p + q = 1[/tex]
[tex]p^{2} +2pq+q^{2} =1\\[/tex]
where,
[tex]p[/tex] = frequency of the population's dominant (A) allele
[tex]q[/tex] = frequency of the population's the recessive (a) allele
[tex]p^{2}[/tex] = percent of homozygous dominant (AA) individuals
[tex]q^{2}[/tex] = percent of homozygous recessive (aa) individuals
[tex]2pq[/tex] = percent of heterozygous (Aa) individuals
As given in the question,
the frequency of the "AA" genotype = 35% the frequency of the "aa" genotype = 50%Therefore, the frequency of "A" allele is,
AA = 35% which means that [tex]p^{2}[/tex] = 0.35, by definition.
If [tex]p^{2} = 0.35[/tex] , then [tex]p =\sqrt{0.35} = 0.59[/tex], again by definition. Since p equals the frequency of the A allele, then the frequency of A allele is 59%.
And, the frequency of the "a" allele is,
Since p = 0.59, and p + q = 1, then q = 0.41;
The frequency of a allele is by definition equal to q.
[tex]q = 1- p\\ q = 0.41[/tex]
So, the frequency of the "a" allele is 41%.
Hence the correct answer is, A = 59% and a = 41%.
