What characteristic of viruses distinguishes them from cells?
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.
how is energy lost from from an ecosystem?
Answer:
Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.
How does the CONTROL GROUP setup in an experiment differ from the other setups in the same experiment?
Answer:
the control is constant and doesnt change where as the other variables would be changing
Explanation:
Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.
Remember:
• Materials that mealworms use (arrows going in) are reactants in chemical changes
• Materials that mealworm produce (arrows going out) are products of chemical changes
When mealworms eat, chemical changes take place inside the mealworms. Chemical changes rearrange atoms. Bonds are broken in reactants. And new bonds are formed in the products.
Evidence of a chemical reaction includes a color or temperature change. Evidence of a chemical reaction can also be a gas or solid product made.
I think when a mealworm takes in_____
Level 4 responses should show potato/food arrows entering the mealworm, feces (and possibly urine) arrows leaving the mealworm and CO2 arrows leaving the mealworm.
Level 2 or 3 responses may show a variety of forms of matter without focusing specifically on molecules containing carbon atoms.
Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.
Level 4 responses should describe chemical energy moving from the potato into the mealworm and possibly chemical energy in the feces leaving the mealworm.

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.

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.

Answer:
Volcanoes are created over approximately 10,000-500,000 years by thousands of eruptions -- each lava flow covering the one before it. In the case of oceanic island volcanoes, lava erupts first from fissures, or cracks, on the deep ocean floor. The flows continue to build up and finally an island emerges from the sea.

Answer:
b A moveable moveable joint joint that that allows allows back back and and forth forth movementmovement
Explanation:
A moveable joint that allows back and forth movement. Therefore, the correct option is B.
What is moveable joint?A synovial joint, commonly referred to as a movable joint, allows for a variety of motion between bones. Limbs and other areas of the body that require movement have movable joints.
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.
Therefore, the correct option is B.

Which organism turns nitrogen back into nitrogen gas?
A. denitrifying bacteria
B. nitrogen fixing bacteria
C. decomposers
D. nitrifying bacteria
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.

The form of cellular transport that expends the cell's energy is known as… *
Assisted transport
Passive transport
Active transport
Facilitated transport
Answer:
C- active transport
Explanation:
Because energy is required in this process, it is known as 'active' transport. Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. Active transport often takes place in the internal lining of the small intestine.
Answer: C. Active transport. In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement. Please mark brainliest!
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?
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.
