Answer: Flowers (and to be more specific), this includes a fruit which may or may not be your regular "fruit".
Explanation: All angiosperms are flowering plants which include a flower and a flower that produces fruit.
A. A web of hyphae hold water near the roots.
O
B. The fungi make and release glucose and other sugars that the roots absorb.
O
C. The fungi may help trees share carbon compounds through their roots.
O
D
. The fungi help anchor plants in the soil.
A and C are the two benefits that the fungi provide the plants: A. A web of hyphae holds water near the roots. C. The fungi may help trees share carbon compounds through their roots.
Fungi are a diverse group of eukaryoticorganisms that include microorganisms such as yeasts and molds, as well as macroscopic fungi such as mushrooms and truffles. They obtain nutrients by breaking down organic matter in their environment and play important roles in nutrient cycling and decomposition.
The hyphae create a network that increases the surface area of the root system, which helps plants to absorb more water and nutrients from the soil. The hyphae also help to retain water near the roots, which is important during periods of drought.
The mutualistic relationship is known as mycorrhiza. Some fungi can even help to connect the roots of different plants, allowing them to share nutrients and resources. This network of connections is called the Wood Wide Web. The fungi can facilitate communication between trees and even help to transfer nutrients and chemical signals between them.

Answer:
b-c
Explanation:
There are many different views on how fungi help trees. Some people even say that trees use them to communicate hormonal signals. So this question has different answers depending on who you ask. But that is what I think is right dont bet on it though.
Gradually as the result of many intermediate steps is my answer because as life on Earth for example started off with simple atoms making molecules, and as the time went past more complex compounds were be produced. And from there later on unicellular organisms started appearing. Nothing in evolution that I know of happens in a short time, at least from the human perspective.
Geographic isolation is the main cause of speciation.
Hybrid organisms always produce sterile offspring.
If a population is spread out over too large area, they may become extinct.
Speciation can only happen when a population has very low genetic diversity.
-----
A population of oak trees is separated by a large canyon. Which of the following is most likely to occur?
The two populations will show cospeciation.
The genetic variation between the two populations will increase.
Natural selection will cause one population to die, and the other to live.
Both populations will stop evolving.
-------
Choose ALL the answers that apply.
Extinction:
only happens above the species level
cannot happen to more than one species at a time
can be caused by habitat destruction
happens when a species or population dies out
-------
Which of the following statements is true?
Gene flow evens out genetic differences between populations.
Genetic drift increases the genetic differences between populations.
Natural selection, mutation, and genetic drift are random events.
The bottleneck effect increases the genetic diversity of a population.
---
A species is endangered if it _____.
no longer exists anywhere on earth
is in danger of becoming extinct
is not native the environment
has high genetic diversity
---
Genetic drift _____.
is a predictable event
increases genetic differences between populations
happens when random events change the genotype of a population
happens when well-adapted organisms survive and reproduce more often than poorly-adapted organisms
Answer: C, If a population is spread out over too large area, they may become extinct.
Answer:
A species is endangered if it is in danger of becoming extinct
