Lichens are not single organisms, but algae and fungi that function together. The algae use photosynthesis to make food for both organisms. The fungi produce digestive chemicals and absorb nutrients for both organisms.
How does the biological activity of lichens cause weathering in rocks?
Answer options with 4 options
A.
Lichens cause friction as they grow, which weathers the rocks.
B.
Lichens produce chemicals, which dissolve and weather the rocks.
C.
Lichens take in water, which freezes in cracks and weathers the rocks.
D.
Lichens absorb heat during photosynthesis, which weathers the rocks.
Answer:
The correct answer is B
Lichens produce chemicals which dissolve and weather rocks

A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.
The correct answer is:
Option C. have a complementary shape to the substrate.
This can be explained as:
If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.Activation energy is the minimum amount of energy needed for the reaction.If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.Therefore, the active site should have a complementary shape to the substrate.

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!
Answer:
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.
However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.
Help I need to turn this in asap
Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.

What organism are tertiary (3rd level) consumers
Answer:
Third-level consumers are any organisms big enough to obtain energy by feeding off lower-level consumers. These are also called tertiary consumers. For example, in a forest ecosystem, snakes eat toads. Heron and large fish, such as bass and walleye, consume smaller fish, frogs and crayfish.
Explanation:
Answer:
The larger fishes like tuna, barracuda, jellyfish, dolphins, seals, sea lions, turtles, sharks, and whales are tertiary consumers Explanation: They feed on the primary producers like phytoplankton and zooplankton, as well as secondary consumers like fish, jellyfish, as well as crustaceans.

two glass tubes are placed in water one of them has very concentrated sucrose solution while the other has a concentrated sucrose solution after an hour what will happen to the liquid levels in the glass
Answer:
The liquid levels in the solution will become more dilute (have more water) due to Osmosis.
Explanation:
This is because Osmosis moves down a concentration gradient so the water outside the solution will become more concentrated and the solution will become more dilute.
How are stem cells nurtured to form a tissue/organ?
Answer:
Stem cells have the capacity to proliferate and to differentiate into relatively mature cells of various types. Embryonic stem cells can become any organ in the body and do so when implanted into a blastocyst. In principle, then embryonic stem cells could be used to replace any organ in the body.
