Answer:
D. all of these
Explanation:
The reason is because all of the above are TRUE.
A. The plant may compete with other plants for light.
It feels like Plants and Trees are just stuff growing, but they actually compete with other plants, some don't do that much, but some do that, so that new plant may do it to get more light and might put more shade on other plants, which is dangerous for other plants.
B. The plant may become another food source for animals.
This is pretty normal, I mean, the thing here is that any plant is vulnerable to being eaten by an animal.
C. The plant may be poisonous and harmful to animals.
Yeah, like in choice B, the same thing, the plants are always Vulnerable to be eaten by hungry animals, and if an animal eats it... then it might get a disease or might just die.
So if these are all correct, then the answer HAS to be D. All of these
Answer:
D. All of these
(P.S. I got it right on Study Island)

13. Give one use for ethyne.
Answer:
Ethyne is useful for artificial ripening and preservation of fruits. It is useful in acetylene lamps to generate light. Ethyne is used to prepare various organic compounds. It is also useful to manufacture important organic compounds like acetic acid, acetaldehyde, ethyl alcohol and polymers like PVC, etc.
Explanation:
Since ethyne burns with a very hot flame, one of its most notable applications is in oxyacetylene gas welding and oxyacetylene gas cutting. When ethyne is subjected to combustion with oxygen, the flame created is known to have a temperature of roughly 3600 Kelvin.

Based on the graph, it can be concluded that the isotope which is most likely to be found with 6.25% of its original amount in 6 billion years is
Uranium-238
Thorium-235
Potassium-40
Rubidium-87
Potassium is most likely to be found with 6.25% of its original amount in 6 billion years because the half life of Potassium-40 is 1-1.5 billion years in graph. Thus the correct option is C.
If it half in 1 to1.5 billion years = 50% gain
1-1.5 billion years = 25%. gain
If we do that 2 more times we will get 12.5% and then 6.25% gain.
What is half life?
Half life is defined as the time required for half of the atoms of a radioactive substance to become disintegrated.
Our estimate is about 1-1.5 billion years so repeating that about 4 times we get around 4-6 billion years for it to gain 6.25%. From this it can be concluded that Potassium-40 as since it comes the closest to remaining at 6.25% its original amount after approximately 6 billion years.

Compared to many other liquids, water has a high heat of vaporization, which means a relatively large amount of heat must be added to the water before the water molecules are moving fast enough to escape the surface as a gas. Which of the following explains why water has a high heat of vaporization?
A Adding heat to the water causes the molecules to move around, and the motion keeps pushing them back below the waters surface
B As water molecules heat up they tend to form more hydrogen bonds with each other, making it difficult for any of the molecules to vaporize.
C Water molecules have a relatively high molecular weight compared to other molecules, so more energy is needed for the water molecules to vaporize.
D Enough heat must be added to water molecules' hydrogen bonds to break the bonds and provide the molecules enough energy to escape the surface..
Answer:
D
Explanation:
Water has a fairly high specific heat, which means that enough heat must be added to it to break the hydrogen bonds between the molecules, allowing them to move freely from each other and escape the water's surface.
Sulfates are considered secondary pollutants because.
Sulfates are considered secondary pollutants because they result from the transformation of primary pollutants.
Reason: Primary pollutants are pollutants emitted directly into the environment while secondary pollutants are emitted after they are formed in the atmosphere.

b. Write a simple word equation to show how NPP is derived from GPP :
The net primary productivity (NPP) and the gross primary productivity (GPP) are related such that: NPP = GPP - Respiration
What is NPP?NPP refers to the net primary productivity of ecosystems. It is the amount of sugar made from photosynthesis when the amount of sugar burned during respiration has been deducted.
The total amount of sugar made during photosynthesis is the Gross Primary Productivity (GPP). This amount does not include the amount of sugar burned by respiration.
Thus, the equation relating the 3 variables would be:
NPP = GPP - Respiration

A fossil of a new primate species is discovered. scientists find evidence that members of this species traveled long distances without putting their hands down on the ground and used tools. which trait would the fossil most likely have? a foramen magnum at the back of the skull a curve in the lumbar region of the spine a femur angled outward an opposable big toe
The trait would the fossil most likely have is a curve in the lumber region of the spine.
What is the concept of fossil?Fossils are remains or traces of animals and plants preserved in rocks. Remains are parts of an animal (eg bones, teeth, scales) or plant (eg trunks) and traces are evidence of its existence or activities (eg footprints).
From the fossils it is possible to see the evolutions that the animals suffered in this case it was a curve in the lumber region of the spine.

3. What would be an example of deposition?
Answer:
frost
Explanation:
Frost is the deposition of water vapour from humid air or air containing water vapour on to a solid surface. Solid frost is formed when a surface, for example a leaf, is at a temperature lower than the freezing point of water and the surrounding air is humid.
In sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf.

Seafood watch has made several unsustainable fishing practices illegal, is a true statement.
What is a Seafood watch?Seafood Watch is a program sponsored by the Monterrey Bay Aquarium; recommendations for which seafood to buy or avoid; consumers and businesses to become advocates for "ocean-friendly".
Seafood Watch has had an immense influence on decisions regarding illegal fishing practices and has helped design sustainable seafood environments due to their lists of seafood that should be eaten without worries.

#SPJ4
Answer:
False.
Explanation:
Just took the test. Also... It is false because Seafood Watch is not a legal authority and does not have the power to make fishing practices illegal. Seafood Watch is a program run by the Monterey Bay Aquarium that provides recommendations and guidance on sustainable seafood choices based on scientific assessments of fisheries and aquaculture practices. It aims to inform consumers and promote sustainable fishing practices but does not have legal authority to enforce regulations or make fishing practices illegal. That responsibility lies with governmental bodies and regulatory authorities.
