The Asian longhorned beetle is native to China and Korea. The beetle is thought to have entered the United States by means of untreated wooden packing crates. The beetle larvae make tunnels and feed on wood of a wide variety of trees like maple, elm, willow, and birch. Infestation by a large number of these beetles can result in the death of the trees.
Which is the best measure that the United States government can take to limit the introduction of more beetles?
Responses:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Prevent growing trees in and around shipyards.
Introduce predators of these beetles from China or Korea.
Require an inspection and treatment of all wooden packing materials before being imported.
Cut all trees that are infected or are at risk of being infested by the beetles.
My first answer would be to inspect all wooden packaging materials before being shipped, since that seems to be the way they are being transported from China and Korea to the United States.
My second answer would be to release predatory species concerning this native beetle species to evacuate or kill of the beetle community in the United States. Although, that could create more problems with more non-native species (of the United States), reasoning the first answer to be the best.
The other answers would most likely be worse, since the extermination of possibly infected trees would just kill the trees, which is something we are trying to stop from happening. If we prevent those trees from growing in/around shipyards, the species could still travel through the packaging if it is brought further onto land or use other modes of transportation. Also, the trees were already growing there in the first place, so then 'preventing' them from growing would just lead back to killing the trees that could be infested.
Answer:
Explanation:
Prevent growing trees in and around shipyards.
Write a clam about how does a Gramma Ray has the most energy
Answer:
Yuh
Explanation:
Because a gamma ray has higher frequency waves, and those high frequency waves contain the most energy. They have short wavelengths but high frequencies, therefore, because of those high frequencies, that is why it contains the most energy among them.
Why are tides on Earth higher than normal during spring tides?
-The Moon cancels out the gravitational pull of the Sun on Earth.
-The Sun comes closer to Earth and increases its pull.
-The Moon comes closer to Earth and increases its pull.
-The Sun combines its gravitational force with that of the Moon on Earth.

Students' food preferences for entrees in the cafeteria at Hazzard County High are presented in the graph. A lunchroom worker might conclude that
A) more students prefer mystery meat over 'other' entree choices.
B) about 26% of the student body would prefer to have pizza at lunch.
C) the majority of students would prefer to have either nachos or mystery meat.
D) only 39% of the students' favorite meal is something other than pizza or nachos.
Eliminate
A lunchroom worker might conclude that the majority of students would prefer to have either nachos or mystery meat. Thus, option C is correct.
What is food waste?
The food is important for the animals as well as plants and other living individuals as it gives them energy when cells use the food in cellular respiration, and based upon the energy most of the work is done, such as body repair, cell division, growth, etc. As the population grows, the rate of food cultivation cannot keep up to feed everyone, so food waste must be avoided so that everyone gets the required amount of food.
In an attempt to save money, the lunchroom staff sent out student questionnaires to see which foods students preferred, and it was found that pizza was the favorite food of about one-third of the students.
Therefore, A lunchroom worker might conclude that the majority of students would prefer to have either nachos or mystery meat. Thus, option C is correct.

How does passive transport come into play in oxygen's journey through our body?
In the alveoli of the lungs, oxygen frequently diffuses from the air into the erythrocytes and blood plasma.
What is passive transport?Diffusion is a form of passive transport where molecules migrate from a high concentration to a low concentration, if you didn't know. Therefore, it follows that the oxygen content of the air must be higher than that of the blood.
Passive membrane transport methods are the most direct. Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.
Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.
Therefore, Passive transport is a term that refers to both osmosis and diffusion. They don't need any power.

Answer:
2
Explanation:
Energy is transferred between organisms in food webs from producers to consumers.
The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants.
Answer: between organisms in food webs from producers to consumers.

A student has two solid blocks that have different masses. The student knows that each block is composed of a pure substance, but she wants to know if the blocks are composed of the same pure substance. Which of these would best show that the blocks are composed of different substances?
A.
Both blocks sink when placed in water.
B.
Both blocks can be scratched by a piece of glass.
C.
One block conducts electricity and the other does not.
D.
One block has a greater volume than the other block.
Answer: I think the answer would be (D) because mass and volume are kinda different and If one has a different volume then it would have a different mass right?
What best describes ribosomes?
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

What do you predict might happen if someone introduced a new species that could eat large amounts of algae at a rapid pace, outcompeting other species already present? Describe what you think might happen, making sure to specify how at least three of the organisms that might be affected and giving a detailed explanation for each organism. Make sure to include in your answer at least one organism that does not eat algae.
Answer:
Small fish, crustaceans, and water-dwelling insects eat algae, so they are going to be affected if an new species is introduced and is water based, also the new species its the algae at a rapid pace, a bunch of organisms will be in danger because some of the organisms eats algae as a primary source of food. If there is something that can make this species go extinct for sometime until it is possible algae can grow as fast as they eat it, then there would be a bunch of sea creatures/organisms affected by this huge change. Not only will the small fish, and other sea creatures/organisms will be affected but it'll also disrupt the ocean food chain, including us human! Because we eat fish, some people depend on algae because if the algae kept getting ate up by this "new" species EVERYTHING else would be also disrupted. Microscopic animals wouldn't have enough food, fish wouldn't have enough oxygen and plants would lose some of the carbon dioxide they need to grow, so these organisms DEPEND on algae for their LIFE!
