What is the similarity between a pine tree and a daisy?
We can confirm that the similarities between a pine tree and a daisy are that they both contain plant cells and therefore rely on photosynthesis to sustain themselves.
What do these organisms have in common?The first similarity is their classification as plants. Both organisms contain plant cells, along with plant-specific organelle that allows them to complete the functions they rely on. One such function is photosynthesis, a process by which plants turn sunlight into nutrients needed to survive.
Therefore, we can confirm that the similarities between a pine tree and a daisy are that they both contain plant cells and therefore rely on photosynthesis to sustain themselves.

a) Popular sovereignty is defined as a state or a country's government authority that is created by the people and is maintained by the people and is ruled for the people.
b) Separation of powers is basically dividing the government system into branches so that all branch has a specific authority to maintain a balanced system where no one has too much power.
c) Unalienable rights are rights that cannot be taken away from individuals forcefully by other people through any means. (Life, Liberty, Property)
d) Limited government is a system where a government has limited power over the authority they have on itself. A government creates a rule, it follows the rule and the consequences just like all the other people.
#3
Of the above vocabulary, I believe the Separation of powers to be the most important because with less power a government has, the more stable the system becomes. A more balanced government can lead to a country being peaceful and stronger.
#4
Over the course of the Enlightenment Period, philosophers like Hobbes, and Locke observed the change of political governing. Of course, there were disagreements on what kind of system they should establish. But one thing was clear that too much power to one monarch or one system of government, the country is going to see another revolution.
#5
The US. Constitution created a government system called a Democratic system. Incorporating the freedom to the separation of powers, this system works pretty effectively and minimizes the use of the law.

Which Biome?
An ecologist collected climate data from two locations. The graph shows the monthly average
temperatures in the two locations. In Location A, the total yearly precipitation is 273 cm. In location B, the total yearly precipitation is 11 cm. PLS help!
Answer:
More organisms are present on location A.
Explanation:
Due to more yearly precipitation, there is more vegetation present on location A. Due to the presence of this vegetation, more organisms are present because there is more food available for organisms as compared to location B. Due to less precipitation, there is less or no vegetation is present on location B and organisms are present in less number due to harsh environmental conditions and no food availability for organisms.
The biome has location A. Thus, the correct option is A.
What is biodiversity?
Biodiversity is all the different kinds of life living in a particular area like the varity of animals, plants, fungi and microorganisms like bacteria and virus that plays a major role in framing of natural world usually three levels of biodiversity are observed and these are genetic species, and ecosystem diversity.
Biodiversity is very important for the process that's support all life present on earth including human.An ecosystem have each and every organism and the relation between physical environment by which they interact. The function of ecosystem is to satisfy the need of humans by supplying them services and goods from nature.
Ecosystem is the branch of science which deals with the study of relationship between living organisms and natural phenomena. Ecosystem is the system in which both living as well as nonliving organisms are present in a particular location.

Construct a Punnett square for the following cross. A woman who is a colorblind carrier marries a man who is colorblind. What will be the chances of their sons also being colorblind? What will be the possible phenotypes of their daughters?
By colour blindness you mean red-green colour blindness I guess because there are different kinds of colour blindness.
Red-green colour blindness is a s.e.x-linked recessive trait disease, which is encoded on the X chromosome. So following are the result of a cross of colour blind men and carrier women:-
1 normal boy (XY)1 Normal girl (XX)1 Carrier girl (XcX)1 Affected boy (XcY)First cross, by the method of punnet square
Look at pictures now!
Conclusion: there are 50-50 chances of both the result.

Slugs are mostly made of water, and CELLS. Every living thing is made of TONS and TONS of cells. Cells of a slug hold its water. A slug isn't happy if it doesn't have LOTS of water in its cells. If you sprinkle salt on a slug they will shrink and die :(
WHY?? Please include: OSMOSIS, HYPERTONIC, SALT, WATER, AQUAPORIN and CELL MEMBRANES in your response.
Answer:
A slug would shrink and die if you were to sprinkle salt on in because it would cause water to leave the cells of the slug through the aquaporins in the cell membrane. This is because through osmosis water balances itself with the solute to reach equillibrium. When you pour salt on the slug you are making the outside a hypertonic solution that is going to draw out the water in the slug's cells.

Which is true about a valid scientific hypothesis
Glucagon and insulin are described as being part of a negative feedback loop. Describe how these two molecules work together in this kind of a feedback loop to prevent blood glucose levels from getting too high or too low.
When blood glucose levels are too high, Insulin is produced by the Pancreas and binds to receptors in our liver to convert glucose to glycogen where it is stored.
when blood glucose levels are too high, Glucagon is produced by the Pancreas and binds to receptors in our liver to convert glycogen back to glucose to be used by the body.
in each case, blood sugar levels return to normal range. this is called homeostasis.
