The energy required for organisms to respond to the environment comes from:.

Answers

The energy required for organisms to respond to the environment comes from the sun.

What is the importance of the Sun in the ecosystem?

Light energy, which also comes from the Sun, is essential for photosynthesis, a process in which green vegetables transform carbon dioxide and water into glucose, lipids, proteins, vitamins, nucleic acids, releasing oxygen into the atmosphere.

The sun is the basis of life, because if we analyze the food chain, its base comes from the photosynthetic beings that provide food for this chain to occur.

write 7 differences between cell and virus.​

Answers

Hey there! Here are 7 differences between a cell and a virus:

A cell is a significant structural and functional unit of all living organisms. Instead, a virus is an infectious agent that is considered non-living. The cell is a living component, unlike a virus that is a parasite. Cells are present in a living form, on the other hand, the virus is present in both living and non-livingA virus doesn’t contain any kind of cytoplasm, cell wall, cell membrane, ribosome or mitochondrion, whereas a cell contains all of these (depending on what kind of cell it is). Many viruses do not even have a membrane, often formed of only a protein capsid containing the DNA or RNA based genome. Cells can exist independently like bacteria or can be as a part of larger organisms like our own cells in the body. Viruses on the other hand are non-living infectious particles that are dependant on a living host to reproduce.Cells reproduce through binary fission and mitosis or meiosis. When a virus replicates, it uses lytic fission to do itVirus particles are slightly smaller than a cell.

what does it mean when a plant photosynthesizes at maximum speed?

Answers

Answer:

High stomatal conductance

Explanation:

Plants with a high photosynthetic capacity have a high stomatal conductance, in the absence of environmental stress (Reich et al., 1999, 1997). This enables plants with a high photosynthetic capacity to gain carbon rapidly, at the cost of high rates of water loss.

how has climate change over geological time and how may it change in the future?

Answers

Answer:

Climate has generally changed from warm to cool globally mostly because of glaciers. Our climate can be changed in the future by the glaciers, also. Think about it this way, glaciers in the south pole melt, and the sea levels rise. Wind currents shift the glaciers and ice shelves, so they break. This will cause the world to overheat, and sea levels to rise. That's how our climate has and will change over time.

the owl in this diagram is considered to be a
carnivore
scavenger
omnivore

Answers

Answer: carnivore

Explanation:

To answer this question, we need to define the given answers and look at what the owl eats via the diagram. Then we will decide what the owl is considered to be.

Here are simple definitions for the given answers:

       Carnivore: eats only animals

       Scavenger: eats dead organisms

       Omnivore: eats both plants and animals

       Herbivore: eats only plants

Next, we will look at what the owl eats via the diagram. See attached. The owl eats frogs, snakes, squirrels, rabbits, and mice (these might not be the exact animals, I am assuming based on the picture). All of these are animals that appear to be alive, meaning the owl is a carnivore.

Answers

Answer:

number 3 is the central vacuole and its  large, membrane-bound organelles found in plant cells that act as a storage space for water and other molecules in the cell

Explanation:

Answer:

3. Vacuole

Explanation:

Plant vacuole is a membrane (tonoplast) bound space which contains sap, water, excretory products and other materials (which are not useful for plants).



It occupies 90% of the volume of the plant cell.

Tonoplast, in plants facilitates transport of ion into the vacuole (against the concentration gradient) which causes higher ionic concentration in vacuole than in the cytoplasm.

Some other points:-

 Amoeba have contractile vacuole for osmoregulation and excretory purposes.

Some protists develop food vacuoles by engulfing food particles.

The carbon in the plants and the rabbit is :  Moving in and out simultaneously

The carbon cycle

The carbon cycle explains  the reusing of carbon atoms which enters the earth from the atmospheres and its movement back to the atmosphere ( reuse ).

As the rabbit eats from the leafy plant the carbon it absorbs from the consumption of the plants enters into the atmosphere simultaneously. while as the leafy plants loses its carbon to the rabbit, carbon is added to the leafy plants from the atmosphere.

A) Cities near the coast are near large bodies of water which can
absorb heat during hot periods.
Cities near the coast are near large bodies of water which can
release absorbed heat during cooler times.
B) The temperatures near the coast are more stable than those that
are inland.
C) The temperatures in the inland cities are more stable.
There is more of a variation in temperatures in cities that are
further inland.
D)There is more of a variation in temperatures in cities that are on
the coast.

Answers

There is more of a variation in temperatures in cities that are on the coast is ability of water to absorb and release heat. Thus, the correct option is D.

Why are the most extreme temperatures experienced inland away from the coast?

Because rock and soil have a smaller heat capacity than water, temperature variance is greater in inland places. As a result, land areas lose and absorb heat at a far faster rate than coastal areas.

Because rock and soil have a smaller heat capacity than water, temperature variance is greater in inland places. As a result, land areas lose and absorb heat at a far faster rate than coastal areas.
