What is a Mutualistic relationship?A mutualistic relationship may be defined as a +,+ type of interaction in which both species benefit from the existence of each other. Example includes lichens, mycorrhizae association, coral reefs, etc.
In the question, the Fungi protect the insects from predators and benefit the insects to get survivability, while in return insects spread spores for the fungi and assist them in their reproduction process.
Therefore, both insects and fungi undergo a mutualistic type of relationship through which both species benefit from the existence of each other.

diseases are inherited.
Answer:
Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes. Dominant inheritance occurs when an abnormal gene from one parent causes disease, even though the matching gene from the other parent is normal. The abnormal gene dominates.

Answer:
The correct answer is - these resources take million years to be replenished.
Explanation:
Non-renewable resources are the resources that come from a source that will finish ultimately or run out or can not be replenished in one or more human life cycles. These sources might take million years to replenish.
Most non-renewable resources are fossil fuels, coal, natural gas. Fossil fuels, cols are were formed as the remains of dead plants and animals but takes millions of years to decay, under huge amounts of pressure and heat.

Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one
Answer:
Charakan
Explanation:
The odd one out would be Charakan.
Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).
Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.
Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum, classifying about 480 plants.
Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.
Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.

The microscope is an essential tool in Biology. It provides us with important data on specimens being examined.
The (1) has various magnification (5x, 10x, 12.5x, 15x) which attaches to the body tube. On the other hand, the

magnification of the Objectives. If the eyepiece has a magnification of 10x and the Objective has (9)
then
the specimen's magnification is 400x. In addition, turning the stage knob upward will result to moving the specimen as
seen in the microscope downward while turning the stage knob to the left will move the specimen to the right as seen
under the microscope. Finally, the specimen when seen under the microscope appears (10)
Answer:
The correct answer would be -
1.) objectives
2.) eyepiece
3.) glass slide
4.) coverslip
5.) pencil
6.) mirror
7.) field of view
8.) magnification
9.) 40x
10.) inverted
Explanation:
Objectives of the microscope have magnification (5x, 10x, 12.5x, 15x) which attaches to the body tube. The nosepiece is found between the stage and the eyepiece or ocular lens. Glass slide is the slide where a specimen is placed for the study and covered with a coverslip, bubble should be avoided while placing the coverslip.
Mirrors need to adjust to seeing the field of view by adjusting the light. After computing the magnification there would be a final image of the specimen that would be inverted due to the two lens used here.
Compact Bone is hard and dense but, it is not solid. It is filled with holes and has small canals for blood vessels and nerves.
True
or
not?
The compact bone is hard and dense, but it is not solid; it is filled with holes and has small canals for blood vessels and nerves, which is a true fact as the compact bone is one of the dense bones present in the body.
What is the significance of compact bone?Compact bone is a dense, hard bone tissue that provides structural support and protection to the body, and it is also involved in the storage of minerals, such as calcium, which is important for the strength and density of bones. Haversian canals are present in the compact bone and contain blood vessels, nerves, and other tissues that support the bone.
Hence, compact bone is hard and dense, but it is not solid; it is filled with holes and has small canals for blood vessels and nerves, which is a true fact as the compact bone is one of the dense bones present in the body.

Story #1
Once upon a time, there lived a population of mountain people whose members all had wings but different
types-either bat wings or bird wings. 40% of the population had bat wings and 60% of the population had bird
wings. One day, a storm hit that lasted for several weeks. Those with bat wings were able to fly around and
find food because their wings were water resistant, while those with bird wings were not able to get food
because their feathers were not water resistant and got soaked through. Many of the bird-winged people starved
and did not survive, so their alleles decreased in the gene pool, lowering the frequency of the bird wings in
future generations. Over many generations, the environment had more and more long periods of rain and the
genetic makeup of the population shifted to 10% with bird wings and 90% with bat wings.
What is the trait being described?
What are the variations that exist in this population?
3. How did the event lead to the change in allele frequency?
Alleles?
4. What type of evolutionary mechanism did this story show?
5. Was there an adaptation in this story? If so, identify it.
6. Did the change make the population more or less similar to other populations?
7. Would this increase or decrease reproductive isolation?
Increase or decrease speciation?
8. Did the new population change for the better, worse, or have no effect? Why?
Answer:
The trait being described is the ability to fly in rainy season.
Explanation:
The trait being described is the ability to fly in rainy season. The people with bat wings and people with bird wings are present in the population. The event lead to the change in allele frequency because the population of people with bird wings die due to starvation. Yes, the bat wings were adapted to that environment so they are able to survive. The change make the population less similar to other populations because population of people with bat wings increases as compared to other population. Yes, the new population change for the better of the ecosystem because the population is able to controls the population of other species in the ecosystem.
