Explain why the jet stream looks so different in picture one and picture two. Please refer to the tutorial to answer this question. Please answer using complete sentences.
Answers
Answer:
Picture one is an illustration of the jet stream on the northern hemisphere during summer. In the tutorial it states, the temperature contrast between cold and warm air masses are smaller, so the jet stream is not that strong only travelling at 50-70 mph. Picture two is an illustration of the jet stream on the northern hemisphere during winter. In the tutorial it states the temperature contrast between cold and warm air masses are greater, so the jet stream is very strong travelling at 90-160 mph.
Explanation:
The northern hemisphere's summer jet stream is depicted in figure one. According to the lesson, because there is little to no temperature difference between the warm and cold air masses, the jet stream only moves at 50 to 70 miles per hour, making it weaker. Picture two shows the northern hemisphere's jet stream during the winter. According to the lesson, because the temperature changes between cold and warm air masses are bigger, the jet stream is very powerful and moves at speeds between 90 and 160 mph.
What is hemisphere?The region of Earth of the Equator is called as the Hemisphere. It contains all or a portion of all five continents (Antarctica, Australia, approximatly 90% of South America, nearly one-third of Africa, and some islands off the continental main island of Asia), all four oceans (the Indian Ocean, South Atlantic, Southern Ocean, and South Pacific Ocean), as well as Nz and the majority of the Pacific Islands in Oceania.
Compared to the Hemisphere, its surface is made up of 80.9 percent water, with 32.7 percent of the planet's landmass. Winter lasts from June to August, while summer lasts from Dec to Feb (inclusive) due to the tilt of the Earth's rotation in relation to the Sun and ecliptic plane (inclusive).
What is temperature?A measure of the typical kinetic energy of the atoms or molecules in a system, temperature is a physical variable that conveys hot and cold. The source of heat, the movement of energy from a hotter body in contact with a colder body, is the expression of thermal energy, which is a component of all matter.
A thermometer is used to measure temperature, which is then calibrated using different temperature scales that historically employed different reference points and thermometric substances for definition. The most popular scales are the Celsius scale, originally known as "centigrade," denoted by °C, the Fahrenheit scale, denoted by °F, and the Kelvin scale, denoted by K, with the latter being mostly used for scientific purposes under norms of the.

True or false? A codon is a group of three bases that can specify more than one amino acid.
Answers
That statement is true
A single codon corresponds to one specific amino acid, making the statement false. The codons for tyrosine are the same in both plants and humans, which is true. The start codon signifies the beginning of translation and also encodes for the amino acid methionine, which is also true.
The statement that a codon can specify more than one amino acid is false. A codon, which is a group of three nitrogen bases in nucleic acids, corresponds to one specific amino acid in the genetic code. There are some instances, known as the wobble effect, where different codons may code for the same amino acid, but a single codon does not encode for multiple amino acids.
The codons that specify tyrosine are indeed the same in both plants and humans, reflecting the virtually universal nature of the genetic code. This fact emphasizes the similarity in the way that different organisms translate RNA sequences into proteins.
Regarding the start codon, the statement is true. The start codon, typically AUG, not only signals the beginning of the protein-coding region but also codes for the amino acid methionine.

Which enzyme breaks the hydrogen bonds during replication?
Answers
The enzyme known as helicase plays a pivotal role in the process of DNA replication by effectively breaking the hydrogen bonds that exist between the two complementary strands of DNA.
Explanation:Helicase, a vital enzyme in DNA replication, assumes the crucial task of unwinding the DNA double helix. Its primary function is to disrupt the hydrogen bonds, which are responsible for holding the two strands of DNA together. As these bonds are severed, the DNA strands separate, providing access to the genetic information they contain. This initial unwinding step is essential for DNA replication to proceed accurately and efficiently.

The enzyme responsible for breaking hydrogen bonds during DNA replication is DNA helicase. It unwinds the double-stranded DNA, separating the strands for replication.
During DNA replication, the enzyme responsible for breaking the hydrogen bonds between the complementary nitrogenous bases is called DNA helicase. DNA helicase plays a crucial role in the unwinding of the double-stranded DNA molecule. It functions by traveling along the DNA double helix, using energy from ATP hydrolysis to separate the two strands by disrupting the hydrogen bonds that hold the base pairs together.
As DNA replication progresses, the leading and lagging strands are exposed, making them accessible for the replication process. DNA polymerases can then synthesize new complementary strands on each of the separated parent strands. This process ensures the accurate duplication of genetic information by unwinding and separating the DNA strands and allowing them to serve as templates for the synthesis of new DNA molecules.

If a pure culture of each bacterium was placed in a tube containing lactose as the only food source, and a chemical indicator changed color after a pH change, what would the tubes look like after the bacteria were incubated?
Answers
Answer: There will be change in the tube in which E.coli will be incubated and there will be no change in the test tube in which Shigella is incubated
Explanation:
Lactose Fermentation Test is done to see which bacteria ferments lactose. pH and color indicator is attached to observe the change. The pH goes slightly down because of formation of Acid and due to this reason a color change is also seen during this test.
As E.coli typically ferments lactose so there will change in color and pH in the test tube incubated with E.coli, while there will be no change in the test tube incubated with Shigella.
Which of the following does not describe a function of aggressive animal behavior?

B. Aggressive behavior leads to fights that allow strong animals kill off weaker members of the species.
C. Aggressive behavior is displayed to establish hierarchy without violence.
D. Aggressive behavior is displayed to determine who is allowed to mate
Answers
Answer:
C
Explanation:
Aggressive behaviour is a act of violence not without it
Answer:
The correct answer is option C.
Explanation:
Aggressive behaviour is a type of behaviour which is widespread in the animal kingdom. Animals display this behaviour by expressing it in the form of anger and violence.
Animals use this behaviour mostly to establish its dominant nature in front of the opponent in the competition. This allows animals to either kill an animal in a fight (violence) or establish territorial boundaries and some species compete to mate with the female individual.
Thus, option C is the correct answer.

Your supervisor asks you to set up a pure culture of a bacterial species he is researching. He tells you that this species is a fastidious, halophilic, gram-positive mesophile that does not have catalase or superoxide dismutase. What type of culture medium and environmental factors must you use to grow this organism?
Answers
Answer:
This bacterial species needs to be grown in a nutrient agar of high salt (NaCl) concentration. It needs to be incubated at moderate temperature of between 20°C and 45°C. This species needs to be kept in an oxygen free environment, a sealed jar containing an oxygen- free gas mixture.
Explanation:
Fastidious: indicates that the bacterial species requires special nutrients and specific environmental conditions to grow.Halophilic: refers to "salt- loving" bacteria, who thrive in conditions with high salt concentrations.Gram -positive: indicates that the bacterium tested positive in the Gram stain test. Mesophile: indicates that the optimum temperature fro the bacteria to grow in is between 20°C and 45°C.This species does not have catalase or superoxide dismutase which indicates that this is an obligate anaerobe because both of these enzymes are required for aerobic respiration. This species cannot be exposed to oxygen.Tall height is dominant to short height in pea plants. You have a tall pea plant that you cross with a short pea plant.

Answers
Answer:
The tall parent was heterozygous
Explanation:
If tall height is dominant to short height the only genotype possible for short height is hh, while there are two possible genotypes for tall height, Hh and HH. When HH is crossed with hh all the offspring are Hh, but if Hh is crossed with hh, a quarter of the offspring is HH, a quarter is hh and half is Hh. If the tall pea plants were HH there would only be tall offspring, but because there are some short offspring we know that the tall pea plants must have a genotype of Hh.

B. More liquid is transported by the body to the skin for insulation.
C. Sebaceous glands secrete more sebum.
D. Blood vessels in the skin expand
Answers
Answer:
A. Blood vessels in the skin narrow and contract.
Explanation:
If we will step outside without a coat on a snowy day then our blood vessels in the skin will become narrow and contract. It is a mechanism to conserve heat within our body in cold weather. If the blood vessels in the skin will become narrow and contract then less blood will flow in the blood vessels, this phenomenon is known as vasoconstriction. The blood of our body is warm but the exposure to the cold weather will cause the heat of the blood to dissipate into the environment. But constricted blood vessels will have less blood and hence heat loss is minimized which keeps the internal temperature of the body as normal even if outside environment is cold.
Answer:
A. Blood vessels in the skin narrow and contract.

C. greater than the oxygen combined with hemoglobin
D. only about 1.5% of the oxygen carried in dissolved form
Answers
Answer:
D. only about 1.5% of the oxygen carried in dissolved form is correct answer.
Explanation:
Plasma is a component of blood, it has many functions in our body like fighting against diseases, clotting the blood.
In the plasma, the quantity of oxygen in solution is about 1.5% of the oxygen carried in dissolved form and 98.5% of the oxygen is bound to hemoglobin.
Thus option (D) only about 1.5% of the oxygen carried in dissolved form is correct.
In the plasma, only 1.5% of the oxygen is carried in dissolved form. Most oxygen is carried by hemoglobin in red blood cells.
Explanation:In the plasma, the quantity of oxygen in solution is generally quite small. The correct answer is D. only about 1.5% of the oxygen carried is in dissolved form. Most of the oxygen in the blood is actually carried by hemoglobin, a protein found in red blood cells. Hemoglobin binds to oxygen in areas of high oxygen concentration, such as in the lungs, and releases it in areas of lower concentration, such as in the body's tissues. Only a small fraction of the oxygen — about 1.5% — is dissolved directly into the plasma.

"Some sympathetic preganglionic fibers stimulate the adrenal medulla to release norepinephrine and epinephrine into the blood, producing what is commonly called a "surge of adrenaline." True False
Answers
Answer:
True
Explanation:
Epinephrine and norepinephrine are the hormones secreted by the adrenal medulla and are also called adrenaline and noradrenaline, respectively. During stress conditions, the hypothalamus stimulates the preganglionic neurons of sympathetic division.
These preganglionic neurons stimulate the chromaffin cells to secrete epinephrine and norepinephrine to prepare the body for fight or flight response. The increased level of epinephrine and norepinephrine hormones in the blood is called “surge of adrenaline”
True, the activation of sympathetic preganglionic fibers leads to the adrenal medulla releasing epinephrine and norepinephrine, initiating the fight-or-flight response.
Explanation:The statement you're asking about is true. Some sympathetic preganglionic fibers, upon activation, stimulate the adrenal medulla to release epinephrine (often referred to as adrenaline) and norepinephrine (noradrenaline) into the bloodstream. This response is part of the fight-or-flight response, which prepares the body to face or escape from potential threats. The sympathetic nervous system triggers this response, which originates from neural impulses in the hypothalamus in reaction to stress. When these neurotransmitters are released into the blood, they cause physiological changes such as increased heart rate, increased blood pressure, and elevated blood sugar levels to support the body's need for immediate energy and heightened awareness.
