When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. glycolysis; dihydroxyacetone phosphate the electron transport system; coenzyme Q glycolysis; fructose-6-phosphate the citric acid cycle; pyruvate the citric acid cycle; acetyl CoA
Answer:
glycolysis; dihydroxyacetone phosphate
When fats are used as an energy source, the glycerol portion enters the glycolysis when it has been converted to dihydroxyacetone phosphate. Thus, the correct option is A.
What is the Glycolysis?Glycolysis may be defined as the process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen.
In order to obtain energy from fats, triglycerides must be broken down into fatty acids and glycerol through hydrolysis. The fatty acids enter to Krebs cycle and are converted into acetyl CoA.
While the glycerol portion enters into glycolysis and is converted into dihydroxyacetone phosphate.
Therefore, the correct option for this question is A.

The process whereby the earth’s life changes over time through changes in genes of populations of organisms in succeeding generations is called____.a. emigration.b. mutation.c. natural selection.d. evolution.e. genetic drift.
Answer:
The correct answer is option : d. evolution.
Explanation:
Change in the heritable traits or characteristics of population of a organism over time by the adaption or changes in genes of such population over successive generation is known as the evolution.
These changes that cause the evolution of the biological population is caused by the process of adaption through natural selection that is the ability of the passing beneficial genes from parent to offspring.
Thus, the correct answer is option D. evolution.

While performing an experiment, it is important to:
a. change the control setup
b. test many different variables at the same time
c. reach a conclusion
d. record observations and measurements
Answer:
D
Explanation:
While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.
What is an experiment?The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.
Hence, while performing an experiment, it is important to record observations and measurements, as in Option d.

When a volcano erupts, tiny particles from which of Earth's spheres are released into the air?
atmosphere
biosphere
geosphere
hydrosphere
When a volcano erupts, tiny particles from the geosphere are released into the air. So, the correct option is C.
What is Volcano?A volcano is a geological formation on the surface of the Earth that develops as magma and volcanic ash build up. During an eruption, lava, ash, and gas can escape through a crater or vent that is generally shaped like a mountain.
Explosive or non-explosive eruptions can have a large negative impact on the environment, causing ash fall, landslides, and lava flows, among other things. Tiny geosphere-derived particles are discharged into the atmosphere during volcanic eruptions.
All areas of volcanism contain compound volcanoes, but these volcanic structures are most common at plate convergence zones, where one tectonic plate plunges beneath another towards the earth's mantle.
Therefore, the correct option is C.

The Peppered moth is white with black spots, which helps it blend in with the bark on beech trees. The burning of coal in Great Britain caused many beech trees to become black with soot. Over time, the Peppered moth became all black in order to blend in with the new bark color. What type of example is this? homeostasis metabolism organization adaptation
Answer:
adaptation
Explanation:
Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.
In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.
Therefore, this is an example of ADAPTATION.

Ultra-high-temperature sterilization effectively reduces microbes that cause spoilage. removes only mesophilic microbes. reduces microbes that cause disease. removes all microbes that cause diseases or spoilage. reduces microbes that cause disease or spoilage.
Answer:
kills all microbes that cause disease or spoilage.
Explanation:
There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.
The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.
These mechanisms are used with surgical instruments, the operating room environment.
The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.
Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.

Watch the video “Teen Stress.” Now, imagine that a friend confides in you that he is going to the doctor because he feels that stress might be affecting his blood pressure. He wants you to help him develop a list of questions to ask the doctor. Come up with five questions for your friend to ask about stress and blood pressure.
Answer:
questions:
Should I or can I eat salty foods?
Do I have to check my pressure immediately?
Do I have to follow a balanced diet?
Is it good to do physical activity?
Do I have to worry about the signs of eye flickering and headache?
Explanation:
Blood pressure is regulated by endogenous mechanisms, although these sometimes fail and it is necessary to take drugs to reduce high blood pressure, an example of which is beta-blockers.
Blood pressure is also regulated by diets based on low sodium consumption, necessary calories and with great contributions of nutrients since cardiac or cardiovascular health is also essential in the face of possible formation of atheroma plaques.
The increase in blood pressure with the appearance of atheroma plaques is very common, and it is also the two most frequent causes of AMI (acute myocardial infarction)
Answer:
1)How much does blood pressure rise because of stress?
2)Are there techniques that I can use to cope with stress?
3)Do these techniques help to reduce blood pressure?
4)Is exercise helpful in reducing blood pressure caused by stress?

Answer:
Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
As shown in the graph, oxygen debt occurs just after the end of exercise because oxygen is consumed at faster rate during exercise that leads to increased respiration and body attempts to replace the used oxygen.
