How does this equation represent the law of conservation of energy—that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
Answer:
Energy from the sun goes into making the sugar molecule. This energy is released to make ATP and heat.
Explanation:
6Co2+6H20->C6H12O6(glucose)+6O2(oxygen)
The sugar molecule is created by solar energy. This energy is discharged to produce heat and ATP.
What is the law of conservation of energy?
According to the rule of conservation of energy, energy can only be transformed from one form of energy to another and cannot be generated or destroyed.
This indicates that unless energy is introduced from the outside, a system always has the same quantity of energy. In the situation of non-conservative forces, when energy is changed from mechanical energy to thermal energy yet the overall energy does not change, this is especially perplexing. Energy must be changed from one form to another in order to be used.
In photosynthesis,
6CO + 6H₂O → C₆H₁₂O₆ + 6O₂
Sunlight is used for the light energy required to produce the sugar molecule.
Therefore, the law of conservation of energy is applicable in photosynthesis as energy from the sun is utilized by all living organisms.

Answer: See explanation
Explanation:
a. A social psychologist spends the afternoon at the mall and unobtrusively records how teenagers act in groups.
This is an observation. This is because the social psychologist is gathering data about the behavior of the teenagers and recording it.
b. A positive psychologist measures the relationship between spirituality and happiness.
This is a correlational study as the relationship between two variables are being measured.
c. A health psychologist randomly assigns people to meditate in the morning, at night, or not at all. After eight weeks, people rate their overall moods.
This is an experiment. Here, the independent variable is manipulated and its effect is tested on the dependent variable.
d. A cognitive psychologist sends out a questionnaire to all incoming students to determine their computer skills.
This is a self-report survey. A survey is referred to as a self-report that is used for research purposes as information regarding people are collected.

Answer:
2.) However, after a certain temperature (about 45°C) the bonds within the enzyme molecule that keep its shape, begin to vibrate so violently that they break. This results in the enzyme losing its shape, including the active site's shape. This is called denaturation. As the substrate can no longer fit into the active site, the activity of the enzyme dramatically decreases. Once all the enzyme molecules are denatured, the enzyme activity will completely cease.
Explanation:
Enzymes are organic catalysts which speed up the rate of chemical reactions. Since most enzymes are proteins, they have specific structures which relates to their catalytic abilities.
When heat above the optimal temperature of activity (about 45°C and above) is applied to an enzyme, the structural integrity of the enzyme molecules are compromised. The various quaternary, tertiary, secondary and structures of the protein are destroyed. This also results in the shape of the active site of the enzyme to be distorted. As a result, substrate cannot bind and the enzyme loses its activity.

Which best explains why water boils in a pot sitting over fire?
Heat energy is created from the thermal energy in the air.
Heat energy is transferred from the water to the fire.
Thermal energy from the fire moves to the water in the form of heat.
Thermal energy from the surrounding air moves to the water.
Answer: Thermal energy from the fire moves to the water in the form of heat.
Because according to second law of thermodynamic, heat flows from higher to lower temperature region. Heat is the transfer of energy from an object at higher temperature to an object at a lower temperature. so energy flows from warmer to colder objects

Umm whats the question?
To maintain turgor pressure (the main pressure of the cell contents against the cell wall), cells in both the leaves and stems of most non-woody or herbaceous plants contain
Answer:
They contain a vacuole
(I think what the question is asking for)
Explanation:
The vacuole is what takes up most of the plant cell's mass. It stores water so when you have high turgor pressure, the vacuole presses against the cell wall while when the turgor pressure is low, the vacuole is shrunken.
Hope this helps with your question!

A garden supply company has an advertisement selling beneficial bacteria. They claim that the bacteria will help gardeners grow better gardens because of better soil. What can some bacteria do for soil?
increase clay content
provide water
slow down weathering
improve fertility
Answer:
D. improve fertility
Explanation:
A garden supply company has an advertisement selling beneficial bacteria. They claim that the bacteria will help gardeners grow better gardens because of better soil.
This claim is simply based on the premise or fact that some bacterias can improve fertility of the soil.
Some species of bacterias are living microorganisms that are capable of decomposing organic matter into nitrogen, carbon and other nutrients, which are then released into the soil in a plant available form when in excess and this cycle continues with reproduction of new bacterias.
Some examples of these bacterias are Klebsiella, Anabaenopsis, Beijerinckia, Azotobacter, Clostridium, Anabaena, Nostoc, Bacillus etc.
You have come into possession of a plant with lavender flowers. Knowing that the plant is self-pollinating, you harvest its seeds and plant them. Of the 106 plants that grow from these seeds, 31 have white flowers. Using a Punnett square, draw conclusions about the nature of the allele of lavender flowers.
Answer:
The correct answer is - heterozygous for lavender flowers (Ll)
Explanation:
As it is given that out of the 106 plants, 31 had white flowers which are approximately 3:1 or one-fourth, of the plants. It suggests that white flowers have recessive alleles (ll).
So, the color flower would be dominant for both allele LL or heterzygous Ll and the Punnett square should show the self-pollination
L l
L LL Ll
l Ll ll
It shows that the ratio of 3:1 is possible when there is a heterozygous condition of the flower allele present.

Explanation:
Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism.

Candice is examining a cell under a microscope. She has identified a cell wall, a nucleus, and chloroplast. What type of organism does this cell most likely belong to.
1.plant
2.fungus
3.animal
4.bacterium
Answer:
1. Plant
Explanation:
Only a plant has a cell wall, chloroplast, and nucleus. Since eukaryotes are the only ones with a nucleus, that cancels out bacteria and fungi. Since there is a chloroplast, you can tell that the cell has to be one of an autotroph which gives you plant.
A botanist has recently developed an enzyme called NoGro. This enzyme acts as an
herbicide by preventing cell growth in the leaves of a certain species of tree that is an
invasive plant species in Florida. The botanist wants to test the effects of temperature
on NoGro so that NoGro can be applied to the invasive tree under optimal
conditions on Florida farms. After looking into the background of the study, you
discover that the botanist performing this investigation is being paid by a company
that will make a lot of money if NoGro proves to be useful at eradicating the invasive
tree. How might this affect your view of the research in this experiment?
Answer:
results could be biased and therefore they are not reliable
Explanation:
A conflict of interest is generated when the authors of a given study have any type of interest that could influence their judgments, results and/or conclusions. These conflicts of interest include any relevant financial relationships, personal, religious, political or intellectual interests. To solve this situation, peer-reviewed, well-reputed journals generally include a conflict of interest statement where authors declare all interests that might be perceived as conflicting.
