Answer:
They are in a parasitic relationship with plants.
Explanation:
Mycorrhizae is a fungus root that has a mutually beneficial relationship with roots of the plants and not a parasitic relationship.
Mycorrhizae colonize soil and disperse its thick-walled spores produced on the extra-radicular hyphae. Mycorrhizae are important in natural systems and agriculture as it helps in the regulation of exchange of nutrients and sugar between fungus and plant.
Hence, the correct answers are "They are in a parasitic relationship with plants."

How do scientists say the melting ice can contribute to disease occurrence? Also example
Answer:
In the melting of icebergs, icebergs could potentially contain long-dormant bacteria and viruses. Those viruses trapped in ice and permafrost for centuries, can be reactivated. That means melting those ice could potentially open a Pandora's box of diseases. Including some that have caused global epidemics in the distant past.
Example: babesiosis
As of regular ice. The freezing of bacteria in water isn't just an old practice and ice from unclean sources could also contain disease, when melted and ingested or touched this ice as well could transmit disease not so long-dormant, however still unpleasant.
Example: AIDS

Describe the net movement of water when a dialysis bag containing a 0.2 M sucrose solution is placed into distilled water, which contains no solutes.
a. There will be no movement of water.
b. Water will move into the bag.
c. Water will move into the beaker.
d. There will be no net movement of water.
Answer:
b
Explanation:
The correct answer would be that water will move into the bag.
The 0.2 M sucrose solution in the dialysis bad has a lesser water potential when compared to the distilled water that has no solutes. By law, water moves from the region of higher water potential to the region of lower water potential. The dialysis bag will, hence, act as a semi-permeable membrane and allow water into the bad from the surrounding distilled water.
The correct option is b.

Which statement describes competition within a population?
Several killer whales migrate to a new location.
Two male sea horses fight to win over a female.
Several elk travel together to find and share water.
Different kinds of garden plants take in water from the soil.
Answer:
I think its B if I'm wrong I'm sorry
Two male sea horses fight to win over a female describes the competition within a population. So, the correct option is B.
What is Competition?Competition is defined as an interaction between organisms or species in which both require a resource in limited supply that reduces the fitness of both organisms because the presence of one of the organisms always consumes the available resource which reduces the quantity.
Competition is defined as the fight between different organisms by limited resources. Some examples of interspecific competition between lions and leopards that vie for the same prey and interspecific competition between rice fields with weeds growing in the field, two male seahorses fighting to win over a female.
Thus, the correct option is B.

Which compares the problems associated with radioactive waste created from generating electricity using fusion reactions to waste created from generating electricity using fission reactions?
A. The radioactive waste from fusion reactions becomes less hazardous much sooner than the waste from fission reactions.
B. The radioactive waste from fission reactions becomes less hazardous much sooner than the waste from fusion reactions.
C. Although their radioactive wastes are hazardous for the same period of time, fusion reactions produce less waste than fission reactions.
D. Although their radioactive wastes are hazardous for the same period of time, fission reactions produce less waste than fusion reactions.
Radioactive waste from fusion reactions becomes less hazardous much sooner than waste from fission reactions, nuclear fusion is much safer than fission because it leaves no radioactive waste behind.
What is the difference between the two reactions?Both processes are natural, but they can also be done in a laboratory. While fusion occurs when two atoms are "crushed" to form a single atom of a new element, fission consists of the splitting of an atomic nucleus.
With this information, we can conclude that Radioactive waste from fusion reactions becomes less hazardous much sooner than waste from fission reactions, nuclear fusion is much safer than fission because it leaves no radioactive waste behind.

Birds display a wide variety of courtship behaviors. Which behavior is also a territorial behavior?(1 point)
creating a bower (arch) with interesting objects and defending it from rival males
flashing feathers to show their health and grooming abilities
dancing and calling on a lek (communal ground) with other males, competing for female attention
singing a particular song to help potential mates hear them
Answer: The correct answer is "creating a bower (arch) with interesting objects and defending it from rival mates".
Explanation:
Just took the quiz.
creating a bower (arch) with interesting objects and defending it from rival males is a territorial behavior.
What is Territorial behavior?Any defended area is referred to as a "territory," and most birds are territorial (in the sense that they defend some area, even if it's merely a nest site), at least for a portion of the year.
When a territory is defended, the "owner" has access to one or more resources (or access to resources of higher quality) than they otherwise would. According to what resource (or resources) is (are) being protected, territories can be categorized.
Type A territory, or the area where mating, nesting, and feeding take place (such as courtship, mating, nesting, & foraging).
Therefore, creating a bower (arch) with interesting objects and defending it from rival males is a territorial behavior.

Which molecule in Diagram 11 is used to transport energy to other parts of the plant?
Answer:
The answer is Sugars, or sugar molecules!
Explanation:
The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap.
The molecule is Sugar ,transported principally as Sucrose, but originally as Glucose after photosynthesis and stored as starch in plants.
The sucrose is transported in the Phloem( one of the vascular tissues, the second is the xylem. They are located adjacent o each other.)The process of transportation is called, Pressure Flow Model. The process of moving the sugar through the plants is called Translocation.
There are two regions during transport of sugar in translocation. The source where the sugar is produced, that is the green leaves, and the sink where the sugar is metabolized.
Therefore the high concentration of the sugar at the source([plant leaves) increases the solute potential of the cell in the phloem of the leaves. This set up a gradients that draw water from the adjacent xylem into the phloem by osmosis.
The water influx increases the pressure potential of the phloem sap, and which makes the phloem turgid. The creates turgor pressure because of the increases of the phloem sap (containing sugar).The pressure leads to the bulk transport of the sap contain sugar (translocation) from the source( leaves) to the Sink.
At the sink, the sugar is withdraw . Thus the solute potential rises,(with a drop in pressure potential) and water return by osmosis back to the xylem for the process to continue with another transport.

byun walked 15 blocks in 25 minutes what was his average speed
Answer:
[tex]\frac{3}{5}[/tex]blocks/minutes
Explanation:
Given parameters:
Number of blocks walked = 15blocks
Time taken for the walk = 25minutes
Unknown:
Average speed = ?
Solution:
In this scenario, the average speed is the rate of walking the blocks per unit of time;
Average speed = [tex]\frac{number of blocks}{time}[/tex]
Input the parameters and solve;
Average speed = [tex]\frac{15}{25}[/tex]blocks/minutes
Average speed = [tex]\frac{3}{5}[/tex]blocks/minutes
Genes A and B are neutral. A weakly beneficial mutation arises in the population. This mutation is 100 base pairs away from Gene A and 1000 base pairs away from Gene B. If this mutation were to go to fixation within the population, which gene would be more likely to go to fixation and what is the term for this process? Is there any reason to suspect that one or both of these genes may not go to fixation? Why or why not?
Answer:
Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.
Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close will have a few recombination events and are strongly bounded.
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be.
Genes that express 50% of recombination frequency or more are not linked genes.
To analyze the recombination frequency, we have to know that
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.
And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.
1,000,000 base pairs ------------------ 1% recombination frequency
1000 base pairs -----------------------X = 0.001% recombination frequency
100 base pairs ------------------------ X = 0.0001% recombination frequency
According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.
