Key points. Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
1. cell
2. tissue
3. organ
4. organ system
5. organism
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

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.
Answers
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.

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.

The most basic definition of cellular respiration is that it is cells breaking down food to make energy. True or false?
Answers
Answer:
True
Explanation:
In cells, energy is obtained from food through the process of cellular respiration. In mitochondria, this occurs through aerobic respiration- here, cells breakdown sugars like glucose into carbon dioxide and water and energy in the form of ATP or adenosine triphosphate.
In cellular aerobic respiration:
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

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
Answers
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.

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.
Answers
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

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?
Answers
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.
