What is true about low-level radioactive waste?
Select all that apply.
Most states have a low-level radioactive waste disposal site.
Low-level radioactive materials may be incinerated before disposal so they take up less space.
Supplies used in nuclear medicine are considered low-level waste.
Materials that have not been contaminated by radioactive materials are still considered low-level waste if they have been exposed to neutron radiation.
Answer:
Materials that have not been contaminated by radioactive materials are still considered low-level waste if they have been exposed to neutron radiation.

What are the ways to control starfish populations?The Harlequin shrimp is a native of salt water marine environment. It is found near the coral reefs in the Pacific and Indian Oceans. It drives nutrition by eating starfish. They are very skilled in obtaining the starfish as a prey. They firstly eat the tube feet and soft tissues and then the central disk is feeded upon.
They are also called Hymenocera picta scientifically and are majorly habitats to the coral of the Pacific and the Indian oceans. They belong to the phylum Arthropoda and are invertebrates.
They are two inches in length and specifically eats starfishes. Their feeding mechanism enables the population of the starfish to be balanced as starfishes are the primary food source for them.
Therefore, Scavengers living in the coral reef scavengers living in the coral reef clean up algae and decayed matter. Thus, correct answer is B.

A. the data support his hypothesis so he should investigate if the same change happens in the density of solid water
um i edit if give more info
Answer:
A
Explanation:
His hypothesis is that if the temperature of water is increased, so decrease occurs in the density of liquid water because the volume will increase. The data support his hypothesis so now he wants to check the density of water in solid form with the increase in temperature. He will apply high temperature and investigate the changes occurs in volume. If volume increases it means density decreases and vice versa.

What is the greatest source of canton that enters the ocean from the atmosphere ?
Answer:
Carbon is an element that is essential to all life on Earth. Carbon makes up the fats and carbohydrates of our food and is part of the molecules, like DNA and protein, that make up our bodies. Carbon, in the form of carbon dioxide, is even a part of the air we breathe. It is also stored in places like the ocean, rocks, fossil fuels, and plants.
The carbon cycle describes the flow of carbon between each of these places. For example, carbon continually flows in and out of the atmosphere and also living things. As plants photosynthesize, they absorb carbon dioxide from the atmosphere. When plants die, the carbon goes into the soil, and microbes can release the carbon back into the atmosphere through decomposition.
Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis. The ocean is another example of a carbon sink, absorbing a large amount of carbon dioxide from the atmosphere.
Some processes release more carbon dioxide into the atmosphere than they absorb. Any process that uses fossil fuels—such as burning coal to make electricity—releases a lot of carbon into the atmosphere. Raising cattle for food also releases a lot of carbon into the atmosphere. These processes that release carbon into the atmosphere are known as carbon sources.
Ideally, the carbon cycle would keep Earth’s carbon concentrations in balance, moving the carbon from place to place and keeping atmospheric carbon dioxide levels steady. However, the carbon cycle is changing because of human activity. People are releasing more carbon into the atmosphere by using fossil fuels and maintaining large livestock operations. Deforestation is depleting Earth’s supply of carbon sinks. As a result, the amount of carbon in the atmosphere is rising.

A mangrove community in a coastal area contains mangrove trees, mangrove
water snakes, sheepshead, and Roseate spoonbills. Differentiate between this
biological community, Its populations, and its ecosystem. (1 point)
Think about the relationships between populations, communities, and ecosystems.
Answer:
The difference between the trees and the animals is that they both need each other to survive. The biological community needs samples of the communities, ecosystems, and populations. Also, they need more stuff to combat other things.
Explanation:
A mangrove community is one made from the mangroves and links the freshwater to the oceanic water. The community is formed by mangrove water snakes, spearheads and roseate spoonbills.
There exist a relation between the population as the mangrove habit is dominated by the moist and damp environment. The first level of the community is the mangroves. The second level is that of snakes and spearheads. The third is made by the spoonbills. Both animal and plant communities need each other to survive.Learn more about the mangrove community in a coastal area containing mangrove trees.

Which of the following best describes why the disks rose to the surface faster in the more concentrated hydrogen peroxide solutions?
The higher substrate
Hope this helps ^-^ Diamonds is the name Thanks
The best description of the disks rose to the surface faster in the more concentrated hydrogen peroxide solutions, as the higher substrate concentrations in the more concentrated solutions speeded the reaction. The correct option is d.
What is hydrogen peroxide?Hair bleaching, surface cleaning, and tool disinfection are all done using hydrogen peroxide. It is also utilized in gardening and dental hygiene. Knowing that a highly regarded skin treatment may also be used as a household cleanser may be unsettling.
In the higher-concentration hydrogen peroxide solutions, the discs came to the surface more quickly. The reaction was sped up by the greater substrate concentrations in the more concentrated solutions.
Therefore, the correct option is d. The higher substrate concentrations in the more concentrated solutions speeded the reaction.
