Remember:
• Materials that mealworms use (arrows going in) are reactants in chemical changes

Alchemy is the process of trying to turn non-gold metals into gold. It was practiced hundreds of years ago by scientists who believed that with the right amounts of heat or chemical reactions, they could make gold. After years of experiments and observations, gold was never produced. Which best describes the practice of alchemy? Alchemy was scientific, because scientists practiced it. Alchemy was scientific, because it included observations and experiments. Alchemy was pseudoscientific, because beliefs came before any observations of success. Alchemy was pseudoscientific, because some successful experiments inspired others.

Answer:
Alchemy was scientific, because it included observations and experiments
Explanation:
Scientific research is one that is done through a series not steps or methods. Observation and experiments are part of the steps in a scientific research.
Scientific research is done through investigation of various theories of science as well as formulating hypothesis. Scientists do not just resort to picking random answers concerning the phenomenons around us. They carry out investigations, observations, and would also formulate potential explanations for what is on ground, carry out experiments and then analyze their results to know if they are right or wrong.
Since the question says observation and experiments were done it is scientific

Why do some croplands suffer from excessive soil salinity?
Answers
Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. It can also come about through artificial processes such as irrigation and road salt. Soil salinity can be reversed, but it takes time and is expensive. Solutions include improving the efficiency of irrigation channels, capturing and treating salty drainage water, setting up desalting plants, and increasing the amount of water that gets into aquifers. Mulches to save water can also be applied to crops. Salinity becomes a problem when enough salts accumulate in the root zone to negatively affect plant growth. Excess salts in the root zone hinder plant roots from withdrawing water from surrounding soil. This lowers the amount of water available to the plant, regardless of the amount of water actually in the root zone. If the level of salts in the soil water is too high, water may flow from the plant roots back into the soil. This results in dehydration of the plant, causing yield decline or even death of the plant. Crop yield losses may occur even though the effects of salinity may not be obvious. The excessive use of water for irrigation in dry climates, with heavy soils, causes salt accumulation because they are not washed out by rainfall. ... The practice of waterlogging without adequate drainage has also become a serious cause of soil salinization.

What characteristic of viruses distinguishes them from cells?
Answers
Answer: Viruses, although not living things, do show some characteristics that they are living. Because they can't reproduce by themselves (without a host), viruses are not considered living. They are made of proteins and glycoproteins like cells are. They contain genetic information needed to produce more viruses in the form of DNA or RNA.
They are acellular, that is, they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.
Study Finds Aardvarks Suffering as African Climate Heats Up
Little is known about Africa's elusive aardvarks, but new research says they are vulnerable to climate change like many other species.
Hotter temperatures are taking their toll on the aardvark, whose diet of ants and termites is becoming scarcer in some areas because of reduced rainfall.
Drought in the Kalahari Desert killed five out of six aardvarks that were being monitored for a year, as well as 11 others in the area.
The aardvarks' body temperatures plummeted during the night because they were not getting enough energy from diminished food sources. They tried to conserve energy by looking for insects
during the warmer daytime, but their efforts to adapt could not save them
Researchers said some birds, reptiles and other animals use aardvark burrows to escape extreme temperatures, reproduce, and hide from predators. They could have fewer refuges available ir
aardvark populations shrink because of rising temperatures, they said.
The aardvark, which lives in many parts of sub-Saharan Africa, is identified as an animal of "least concern on an international "red list of threatened species. There are no indications that the
population is changing significantly in southern Africa, though it is speculated that numbers may be declining elsewhere because of habitat destruction, the bushmeat trade and other factors.

The claim of an author simply refers to what the author is trying to point out. Here, the claim of the author is that aardvarks are a keystone species and their decline could have a trophic cascade effect on the ecosystem.
The author stated that aardvarks are vulnerable to climate change like many other species and this could lead to their reduction. Some birds, reptiles and other animals use aardvark burrows to escape extreme temperatures, reproduce, and hide from predators. Therefore, the reduction of aardvarks will have a negative effect on the population of such animals.

They are a keystone species, aardvarks' extinction might cause an ecosystem-wide cascade of trophic levels. The correct option is B.
Thus, An author's claim simply refers to what the author is attempting to make a point about. Aardvarks are a keystone species, according to the author, and their extinction could have a negative trophic cascade effect on the environment.
According to the author, aardvarks, like many other species, are susceptible to climate change, which could result in a decline in their population.
Aardvark burrows are used by some birds, reptiles, and other creatures as a refuge from harsh weather, a place to mate, and a place to hide from raptors. Aardvark populations will therefore be negatively impacted by the decline in aardvarks.
Thus, They are a keystone species, aardvarks' extinction might cause an ecosystem-wide cascade of trophic levels. The correct option is B.

Biofuels are fuels derived directly from living matter. Read this article about a scientist who discovered how one bacterium can transform plants into usable energy. Then answer the following questions. Today, many people read only the headlines of news stories instead of taking time to read the entire article. This habit can lead to misconceptions about the actual story. What misconceptions could someone have by reading just the headline of this article? How are these misconceptions clarified if the entire article is read?
Answers
Answer:
The headline suggests that using bacteria to turn plants into biofuel is a simple process. But reading the article reveals that there were many different types of scientists involved in the process. Also, the headline gives the misconception that this process is so simple that it’s ready to be used. But the last paragraph of the article states that this process has only been done on a small scale, and transforming the process for the entire industry would likely be quite difficult.

These joints have a synovial membrane that secretes synovial fluid, and they are enclosed in a capsule of connective tissue. This fluid helps lubricate the joint and lower friction as the bones move in closer proximity to each other.
Ball-and-socket joints, pivot joints, saddle joints and gliding joints are some examples of movable joints. Different types and ranges of motion are possible with each type of joint.

Which organism turns nitrogen back into nitrogen gas?
A. denitrifying bacteria
B. nitrogen fixing bacteria
C. decomposers
D. nitrifying bacteria
Answers
Answer:
b
Explanation:
part of the nitrogen cycle
Denitrifying bacteria turns nitrogen back into nitrogen gas. The correct option is A.
What is nitrogen fixation?Any natural or artificial process called nitrogen fixation causes free nitrogen, a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites.
Chemically, nitrogen fixation transforms atmospheric nitrogen into ammonia, which is ingested by living things.
In essence, nitrogen fixation transforms atmospheric nitrogen into a form that plants can use more easily.
Nitrate is transformed back into nitrogen gas by denitrifying bacteria, which then reenters the atmosphere. Runoff and fertilizer-related nitrogen enters the ocean, where it interacts with marine food webs.
Thus, the correct option is A.
