Answer:
QWERTY
Explanation:
The table shows the energy that is stored in three types of organic molecules. Energy Storage in Humans A 4-column table with 3 rows. Column 1 is unlabeled with entries Free Glucose in Blood, Glycogen, Lipids (Fats). Column 2 is labeled K cal per Gram with entries 4, 4, 9. Column 3 is labeled Energy Storage (k cal) with entries 40, 600 to 1600, 10,000. Column 4 is labeled Life Support Time with entries Few minutes, 1 day, 30 to 40 days. What is the best conclusion based on this data? Blood is a primary location for energy storage. Fat molecules contain more energy-containing bonds than simple sugars. A gram of glycogen has twice as much energy as a gram of fat. The human body stores approximately 1,000 kcal of glucose.
Answer:
B or Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
The BEST conclusion based on this data is fat molecules contain more energy-containing bonds than simple sugar.
Both glucose and fats are macronutrients that store energy in their chemical bonds.Carbohydrates are polymers composed of monomers or 'sugar molecules' called monosaccharides. Glucose is a simple sugar (i.e., it is a monosaccharide).Lipids (fats) are polymers composed of fatty acids and glycerol.According to data, free glucose contains four (4) Kcal per gram; whereas lipids (fats) contain nine (9) Kcal per gram.In conclusion, the BEST conclusion based on this data is fat molecules contain more energy-containing bonds than simple sugar.

Purple flowers are dominant over the white flowers. The parent generation includes two heterozygous parents. What are the possible phenotypes of these parent offspring
Answer:
Purple and white-flowered individuals.
Explanation:
First, let P represents the allele for purple flower trait and p for white flower trait. PP and Pp would be purple and pp would be white flower individuals.
The parents are two heterozygous individuals, Pp.
Pp x Pp
offspring: PP Pp Pp pp
PP and Pp = purple
pp = white.
Hence, the possible phenotypes of offspring from two heterozygous parents are purple and white-flowered individuals.

Soo-Jung used the subtraction property of equality to solve an equation for y. Which equation could be the one that Soo-Jung solved? 4 y = 12 StartFraction y Over 4 EndFraction = 12 2 (4 y) = 12 y + 4 = 12
Explanation:
Option 1.
4y=12
Dividing 4 both sides
y=3
Division property should be used.
Option 2.
[tex]\dfrac{y}{4}=12[/tex]
Cross multiplying each other,
y=12(4)
y=48
Option 3.
2(4y)=12
Opening bracktet in LHS
8y=12
Dividing both sides by 8 i.e.
[tex]y=\dfrac{12}{8}\\\\y=\dfrac{3}{2}[/tex]
Division property is used.
Option 4.
y+4=12
Subtracting both sides by 4 i.e.
Y+4-4=12-4
y=8
Subtraction property is used.
It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.

What type of rock (granitic or basaltic) would be more likely to contain the mineral quartz Why?
Answer:
I think granitic rock would contain more mineral quartz.
Explanation:
Because the magma cools slowly, crystals of different minerals have time to grow. Molecules in the lava do not have time to arrange themselves to form large crystals. Extrusive rocks have crystals that are too small to see without magnification. A common example of an extrusive igneous rock is basalt.
True or false A hypotheses has been tested many times by different independent researchers but a theory has not
Answer:
true
Explanation:
yea a theory has not tested hypothesis
Answer:
Testing a hypothesis can lead to one of two things: the hypothesis is confirmed or the hypothesis is rejected, meaning it either has to be changed or a new hypothesis has to be created. This must happen if the experiments repeatedly and clearly show that their hypothesis is wrong. It doesn’t matter how elegant or supported a theory is—if it can be disproven once, it can’t be considered a law of nature. Experimentation is the supreme rule in the scientific method, and if an experiment shows that the hypothesis isn’t true, it trumps all previous experiments that supported it. These experiments sometimes directly test the theory, while other times they test the theory indirectly via logic and math. The scientific method requires that all theories have to be testable in some way—those that can’t are not considered scientific theories.

In a coal-burning power plant, the coal is an example of a system _____.
A. Product
B. Throughout
C. Output
D. Model
E. Input
In a coal-burning power plant, the coal is an example of an Input System. So, the correct option is (E).
What is Coal burning power plant?Coal-burning power plants are defined as those plants that produce electricity by burning coal in boilers to generate steam. The steam produced under extreme pressure flows into a turbine, which spins a generator to create electricity, then it cools, condenses back into water and returns to the boiler to start the process.
About 50% of coal is used as the primary fuel for power generation. The main function of a coal fired thermal power plant is to convert the energy available in the coal into electricity where as power plants work by using multiple stages to convert the stored energy coal for usable electricity which is an example of input system.
Thus, In a coal-burning power plant, the coal is an example of an Input System. So, the correct option is (E).

How can Scientific beliefs be used incorrectly to fool people into thinking they are Scientifically founded
Answer:
Is really common that all the studies and scientific advances that we find today, born as an idea or hypothesis (that in a lot of cases is not the same as the end result).
So for example, suppose that a group of scientists is trying to find a cure to a certain disease, and they think that they may have found it, but there are not enough tests (for example they may try it in rats, but not in humans yet)
As the group starts to find results, they may share them (especially if they are positive), and here is when a given communicator/periodic takes this information and makes a claim like "Group of scientist finally finds the cure for...."
So in this case the media is using the fact that a group of scientists "thinks" something as a valid claim to affirm something.
There is also the case where a scientist says something (That has logic and scientific value only in context) and then the media uses some part of the scientist's statement out of context in order to affirm a given idea.

A farmer uses triazine herbicide to control pigweed in his field. For the first few years, the triazine works well and almost all the pigweed dies; but after several years, the farmer sees more and more pigweed. Which of these statements explains why the pigweed re-appeared?A) Natural selection caused the pigweed to mutate, creating a new triazine-resistant species. B) The herbicide company lost its triazine formula and started selling poor-quality triazine. C) Triazine-resistant pigweed has less efficient photosynthesis metabolism. D) Only triazine-resistant weeds survived and reproduced, so each year more pigweed was triazine-resistant.
Answer:
A) Natural selection caused the pigweed to mutate, creating a new triazine-resistant species.
Explanation:
Due to constant use of triazine, the weed will build resistance to it over time unlocking the herbicides codes and making it ineffective.
Natural selection will play out allowing this weeds to bring about a sudden change in their genome that will become resistance, this resistance breed is what will then be produced over time because mutation is heritable and the herbicide then becomes ineffective and the weed continues to multiply and increase in volume.
Why the bass and crayfish benefit from an increased level of phosphate, initially, but then die off
Answer:
Increased levels of phosphate are beneficial to phytoplankton and aquatic plants. In the short-run, this means increased micronutrients for herbivorous and omnivorous fish.
The phosphate, however, reacts with the water to reduce the oxygen levels obtainable in the water. Without oxygen, the fishes die off.
It is not unusual to find that with increased phosphate in water, healthy fishes begin to die off without any other plausible explanation.
The solution is to clean the water or treat it with solutions that impact positively whilst reducing the phosphate levels.

Maria’s father started a fire in the fireplace. He crumpled some paper, lit a match, and soon the logs in the fireplace were burning. In the case, the stored chemical energy in the logs was changed into
Answer:
The options are
A) electrical energy.
B) mechanical motion.
C) heat and light energy.
D) electrical and heat energy.
The answer is C) heat and light energy.
Explanation:
Chemical energy in the wood is lit up by fire and a burning process begins to occur. Burning involves a substance being consumed by fire and fire aids in the conversion of some forms of energy to mainly light energy as a result of the burning flames and also to heat energy as a result of the high temperature in the form of heat which the fire brings into play.
This validates the stored chemical energy in the logs being changed into light and heat energy.
Two species of pine tree are very similar to each other. The pine trees are very different from a species of palm tree. Which statement best describes the characteristics of these trees?
Answer:
This question lacks options; the options are:
A). All of the tree species have the same number of characteristics in common.
B). The two species of pine trees have fewer characteristics in common than the pine trees and the palm trees.
C). The two species of pine trees have more characteristics in common than the pine trees and the palm trees.
D). None of the tree species have any characteristics in common
The correct answer is C.
Explanation:
Living organisms are of numerous and different species. In the order of classification of living organisms, species is the most exclusive and also represents the smallest. However, an organism can have different species on the basis of shared or common characteristics.
Two species are said to be similar if they share or have more characteristics in common. Likewise, different species have less characteristics in common. Hence, in the case of two pine tree species, which are very similar to each other but very different from a species of palm tree. This implies that the two pine tree species have more characteristics in common than they do with the palm tree species.
