Answer:
B. It releases its energy quickly in a single reaction.
Explanation:
Adenosine triphosphate (ATP) is an energy carrying molecule in living systems while Glucose is an organic molecule (carbohydrate) that stores a high amount of energy. Glucose is a monosaccharide and the smallest unit of carbohydrate-containing foods we eat. Chemical energy is stored in the chemical bonds that hold the glucose molecule.
However, during the process of cellular respiration, energy stored in glucose molecule is broken down and transferred to ATP, which stores energy between the phosphate bonds of its molecule. The energy in ATP is released to perform cellular activities when the phosphate bond of the last phosphate molecule is broken.
Although the glucose molecule stores way more energy than ATP molecule, the ATP molecule releases its energy quickly in a single reaction. This makes energy readily available for cellular functions. This property of ATP makes it an active energy source over glucose.
Answer:
B. It releases its energy quickly in a single reaction.
Explanation:
Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. How would you conduct your investigation? In your answer, explain your independent and dependent variable?
Answer:
The student has observed that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow at a faster rate than they grow in plain soil.

To celebrate her recent weight loss, Lisa’s friends decide to take her out for a healthy dinner. Lisa doesn’t drink alcohol because she knows the empty calories will contribute to weight gain. One girlfriend at the dinner has four margaritas and an extra shot of tequila before the food arrives. Is this friend’s behavior considered binge drinking?
Answer:
Yes
Explanation:
In the scenario being described in the question it can be said that Yes, the friend's behavior would be considered binge drinking. This is due to the fact that consuming four drinks or more for women is considered binge drinking, and she had 5. Binge Drinking is defined as when a pattern of drinking that brings a person's blood alcohol concentration (BAC) to 0.08 g/dl or above, which for men is 5 or more drinks, and for women it is 4 or more drinks in less than 2 hours.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.

Which of the following is false? Unselected Under normal conditions, blood PO2 affects breathing only indirectly. Unselected Changes in arterial pH resulting from CO2 retention or metabolic factors act through the peripheral chemoreceptors. Unselected When arterial PO2 falls below 60 mm Hg, it becomes the major stimulus for respiration. Unselected Oxygen levels are the primary stimulant of respiration.
Answer:
The sentence that says: Blood PO2 affects respiration only indirectly, IT IS FALSE, since the partial pressure of oxygen gas together with carbon dioxide are factors that DIRECTLY affect respiration.
The sentence that says: Unselected changes in arterial pH as a result of CO2 retention or metabolic factors act through peripheral chemoreceptors. It is FALSE, since the central chemoreceptors together with the peripheral ones can detect the metabolic acidosis generated by the CO2 retention, this is how the CNS receptors capture the CO2 that crosses the blood-brain barrier and stimulates hyperventilation to compensate for this phenomenon and increase the plasma concentrations of partial oxygen pressures.
The sentence that says: in selecting When arterial PO2 falls below 60 mm Hg, it becomes the main stimulus for breathing, IT IS FALSE, since it not only encourages ventilation to promote oxygenation but also activates the renin-angiotensin-aldosterone in order to recover blood volume and thus achieve adequate blood pressure.
In addition, hypovolemia triggers tachycardia and weakening symptoms, which is why the drop in blood pressure is not the main stimulus for breathing.
Explanation:
Breathing is promoted by muscle contraction, medium and high temperatures (that is, in hot or hot climates), partial concentrations of oxygen and carbon dioxide both in the atmosphere and in our blood, and in situations of systemic imbalances such as metabolic acidosis or alkalosis.
When does the separation of sister chromatids occur? A. Meiosis 1 B. Meiosis 2 C. Before Meiosis D. After Meiosis

Q. 35 One treatment for high blood pressure is taking diuretics that prevent the kidney collecting ducts from reabsorbing water. How would diuretics reduce blood pressure? By increasing blood volume By decreasing blood volume By increasing heart rate By decreasing heart rate
The diuretics will increase the volume of urine. That means more water is taken from the blood and excreted. According to Boyle's law, the volume is proportional to the pressure(p1v1=p2v2). It means that if we decrease the volume of blood we also decrease the pressure.
That means second option
Which of these must exist for natural selection to cause change ?
Answer:
The answer is A.
Explanation:
How do the frequencies of the waves compare?
O Wave A has a lower frequency because it has a
smaller amplitude.
O Wave A has a higher frequency because it has a
shorter wavelength.
The waves have the same frequency because they
have the same wavelength.
O The waves have the same frequency because they
have the same amplitude.
Answer:
O. Wave A has a higher frequency because it has a shorter wavelength.
Explanation:
Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
Answer: B.
Explanation: Wave A has a lower frequency because it has a longer wavelength.

Predict what would happen if we had no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body.
Answer:
If there was no system of lymphatic vessels, there would be no drainage of excess fluid from the tissues and the lymphatic fluid would accumulate in the tissues, causing them to swell.
Explanation:
The lymphatic vessel is made up of tiny vessels that are closed at one end and can be found in the spaces in the cells, except the central nervous system and the non-vascular tissues.
The main function of the lymphatic vessel is to move lymph which is a fluid that contains infection-fighting white blood cells to every part of the body.
So, if there was no system of lymphatic vessels, and tissue fluid was moved directly back into the circulatory system throughout the body. the lymphatic fluid would accumulate in the tissues, causing them to swell.
