Earth's polar regions have cold, dry climates because the Sun's rays are at a
1
low angle, and upper atmospheric air is sinking
2
low angle, and upper atmospheric air is rising
3
high angle, and lower atmospheric air is sinking
4.
high angle, and lower atmospheric air is rising
Answers
Answer:
1. low angle, and upper atmospheric air is sinking
Explanation:
Weather can be defined as the atmospheric conditions of a particular area over a short period of time. Some of the elements of weather are wind, humidity, temperature, air pressure, precipitation and clouds.
Basically, the weather of a particular area or region may change hourly, daily, monthly or even annually.
On the other hand, climate refers to the change in the atmospheric conditions and manifestation of weather in a particular area over a long period of time usually 30 years.
In Science, Earth's polar regions refer to the areas that are typically located between the North Pole and the Artic Circles or South Pole and the Antarctic Circles.
The very cold temperatures found in polar regions causes the air to be very dry and as such there's no much atmospheric moisture; reducing the amount of precipitation (rain, sleet, snow or clouds) drastically.
At higher altitudes (heights above sea level), the angle of incidence of the sun's ray (sunlight) is usually at a low angle striking the tilted surface of the Earth.
Hence, Earth's polar regions have cold, dry climates because the Sun's rays are at a low angle, and upper atmospheric air is sinking, which leads to an increase in the amount of heat received.
Earth's polar regions have cold, dry climates because the Sun's rays are at a low angle, and upper atmospheric air is sinking.
Climate of a Polar RegionThe two most important factors in the climate of an area are temperature and precipitation. The temperature of Polar areas are in negative because the sun's rays strike these areas at very low angles.
Due to very cold temeperature there is no moisture in the air, and hence the air is very dry, this is why the Precipitation in Polar areas is too low. Hence, the polar region have cold, dry climates. Therefore, as per above statment we can say that the correct option is 1. Low angle, and upper atmospheric air is sinking.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answers
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

Let’s think about mutations in the context of selection and evolution. Normally, random mutations are very rare, but this process can be accelerated by using DNA damaging agents. Imagine you are working with yeast. Normally, high levels of salt kill yeast. However, you are conducting a random genetic screen to find salt-tolerant mutants. You use a DNA damaging agent (like EMS, or UV light) to damage the yeast DNA, then look for growth on plates with salt.
a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).
Answers
a. Does putting the yeast on salt cause the beneficial mutation? Why or why not?
When the logarithmic growth of cells is interrupted by exposure to a 0.5 to 2 Molar salt solution the aueous solution consisting of KCl, NH4Cl, NaCl, MgCl2 are basically mutagenic in yeast .
Stationary phase cells are not mutated by the treatment.
b. If you screened your mutagenized yeast cell population on caffeine (another substance that normally kills them), could you find caffeine tolerant ones? (assume there is the potential for genetic resistance to caffeine).
For normal tolerance to caffiene the sty1 and pap 1 pathways are not necessary, but generally only sty1 is activated by mutation hence making yeast sensitive for caffiene.

Answers
Answer:
You eat a hamburger and breath oxygen
Oxygen goes immediately from your lungs to blood vessels to cells.
Food molecules in the hamburger are broken down into glucose in the digestive system.
Oxygen and glucose combine to form carbon dioxide, water, and ATP.
Energy is used by cells in your body to function and grow; you exhale carbon dioxide.
The digestive and respiratory systems work together to provide oxygen and organic compounds to the body, which, through cellular respiration, produce ATP and water and release CO₂. The order is A, D, E, B, C.
Every function in the organism needs the energy to occur.
Different systems work together and are equilibrated to achieve correct functioning.
For instance, the digestive and respiratory systems work together to provide oxygen and organic compounds that are used to produce energy through cellular respiration.
Cellular Respiration processCellular respiration is a process through which cells produce energy by degrading organic compounds.Aerobic cellular respiration depends on the presence of free oxygen, and occurs in the mitochondria.It is a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. GlycolisisRespiration begins with the process of glycolysis, which occurs in the cytoplasm.It does not need oxygen to occur. Glycolysis is the process through which the cell partially decomposes glucose and turns it into pyruvate.
Pyruvate enters the mitochondria matrix and turns into Acetyl CoA.
Krebs CycleIt takes place in the mitochondria matrixAcetyl CoA enters the Krebs cycle through which CO₂ is released and ATP, NADH, and FADH₂ are produced.Oxidative phosphorylationThe process of oxidative phosphorylation is constituted by the electron transporter chain + chemiosmosis.It occurs in the internal mitochondrial membrane. It uses electrons from NADH and FADH₂ to produce ATP and water molecules.
The correct order of events is as follows,
A) You eat a hamburger and breath oxygen
D) Oxygen goes immediately from your lungs to blood vessels to cells.
E) Food molecules in the hamburger are broken down into glucose in the digestive system.
B) Oxygen and glucose combine to form carbon dioxide, water, and ATP.
C) Energy is used by cells in your body to function and grow; you exhale carbon dioxide.

7. Pedialyte is a beverage which contains the same concentration of ions (K , Cl-, and Na ) as found in the plasma. Gatorade and Powerade mimic (although are not identical to) Pedialyte. Therefore, we might expect that consumption of Pedialyte should not significantly alter the osmolarity of the blood. How would you expect the urine production rate in the Pedialyte group to compare to that of the water group
Answers
Answer:
Less urine production.
Explanation:
The urine production rate in the Pedialyte group is lower as compare to that of the water group because the presence of K, Cl-, and Na ions. The precise combination of electrolytes and sugars in Pedialyte helps in restoring fluid levels and the nutrients in the body that are lost through sweating, urinating, or vomiting and diarrhea. We know that the presence of sodium ions regulation water and electrolyte balance in the body so there is less urine produced by taking Pedialyte group.
The urine production rate in the Pedialyte group to compare to that of the water group -
Pedialyte group - decreased
water group - increased.
The rate of urine output is the urine production in a unit of time. The normal range of urine output is 800 to 2,000 milliliters per day if you have a normal fluid intake of about 2 liters per day.
Drinking Pedialyte increases the ion concentration in the plasma that causes hyperosmolarity. This is sensed by the hypothalamus and releases ADH that leads to more fluid absorption in later DCT and collecting tubules that leads to decrease urine output. On the other hand, if you drink water, hypoosmolarity in blood plasma which does not sense by the hypothalamus and does not release ADH, and the urine output is more than the previous case.Thus,
The urine production rate in the Pedialyte group to compare to that of the water group -
Pedialyte group - decreased
water group - increased.

Four scientists observed an area of land that had been cleared of all trees and bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted?
Answers
Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.
