Compasses always point north. The magnetic pin in the compass aligns with the top of the planet's magnetic field and points in that direction. A broken compass points east.
Why does a broken compass points east?A strong magnetic field nearby may be the reason a compass points East. A compass may point in that direction if anything has a stronger magnetic attraction than the planet's magnetic field. Power lines, huge batteries, and magnetic metals like iron can cause interference. Their electromagnetic fields decrease quickly with distance.
A compass may point east if the needle's free movement is hindered. Compass needles are free-floating. It can't face North if it's damaged, bent, or blocked by debris. This may explain why the compass needle won't turn.

Living things... oh yes.
The answer here would be "has a heart". Every living thing doesn't necessarily have a heart. Trees and plants do not have hearts, yet they are alive. (Some scientists believe that plants have pulses, though. No heart, but a pulse! Odd, isn't it?)

Your friend shows you the image below and claims that it shows the process of mitosis. why is he or she wrong? (3 reasons)
Answer:
1. The cell splits itself twice
2. 4 resulting sperm cells are made
3. Only half of the DNA is kept per cell
Explanation:
Mitosis only has one diving phase that occurs only on body cells, which makes it have 2 daughter cells. This, on the other hand, has 4 daughter cells. If you notice, after the third set of bubbles, the genome(DNA) is split among 4 cells.
Determine how the sugar in the water affects the petal loss.
Write a sentence that states what you found out about the scientific question you just investigated. Provide enough detail so that a friend who did not do the experiment could learn from your description.
Answer: When you add sugar to your plant's water supply, it changes the ability of the plants to absorb water. In some instances this is helpful such as when the plants are dying off, but in other cases this will damage the plants when the plant is already functioning properly.

5. Read the following passage.
A small amount of oil can be used to produce a large amount of energy. Because of this, oil has changed the way we live. Our cities are built for cars, which run on oil in the form of gasoline. People have grown used to the idea of being able to hop in their car and drive anywhere they want, for a relatively low price. And our country has a large network of gas stations already in place to make this possible.
However, there is only so much oil underground. Once we have taken all the oil from underground, it will not be replaced. As oil starts to run out, the price will keep increasing. Also, oil releases greenhouse gases when burned, but that is not the only effect it has on the environment. Drilling for oil is a difficult process and can cause environmental damage. In the drilling area, organisms can lose their homes or be killed. Oil is also drilled offshore, which means it is drilled from the ocean floor. This can cause problems for marine life. One of the worst outcomes is when oil is spilled into the ocean, because this is very difficult or even impossible to clean.
a) Based on this passage, what are the pros and cons of using oil? (2 points)
Think about the good and bad things that the passage mentions.
b) How might society affect science when it comes to developing oil-based technology? (1 point)
Think about concerns or needs people may have.

Answer: It could be B. or C. I would go with B because it mentions the guard cells
Explanation:
Stomata are composed of two guard cells. These cells have walls that are thicker on the inner side than on the outer side. This unequal thickening of the paired guard cells causes the stomata to open when they take up water and close when they lose water.

B
Explanation:
As the Colorado River carved the Grand Canyon, the land was split and the sides of the canyon grew farther apart. The population of Abert's squirrels in the area was separated by the widening canyon. Over time, scientists noted differences in the two separate populations, including the color of their fur, their size, and their foraging and feeding behaviors. What will happen to the groups of squirrels if they remain separated? How does this relate to genetic variation?
The canyon became a geographic barrier separating the forests and squirrels on each rim. One population of squirrels had become two separate populations that could no longer reproduce. According to National Geographic, this type of speciation is allopatric speciation.

Plant pollen travels from the stamen to the stigma. Which step comes next in the pollination process?
Answer:
the next step would be germination.
Explanation:
Step 1: Pollination
In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.
Step 2: Germination
Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.
Step 3: Penetration of the Ovule
The pollen tubes penetrate the ovule, which contains the female gametes.
Step 4: Fertilization
Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.
Answer:
When a pollen grain moves from the anther (male part) of a flower to the stigma (female part), pollination happens. This is the first step in a process that produces seeds, fruits, and the next generation of plants. The stalk holds the anther and attaches it to the flower. The enlarged basal portion of the pistil where ovules are produced.
Explanation:
When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants.

Can somebody please label the parts of the frog?
Answer: As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk (see Vertebrates). The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom.

In a paragraph (at least 6 sentences)- Introduce Water Striders and tell how they are able to walk on water by explaining the relationship between hydrogen bonding, cohesion, surface tension, and buoyancy.
Answer:
Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water.
Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight. The legs of a water strider are long and slender, allowing the weight of the water strider body to be distributed over a large surface area. The legs are strong, but have flexibility that allows the water striders to keep their weight evenly distributed and flow with the water movement. Hydrofuge hairs line the body surface of the water strider.
