Which statement best describes the relationship between the bending of a ray of light and a black hole?
When light disappears, it causes a black hole to come into existence.
A ray of light has gravity that will cause a black hole to move toward it.
Gravity from a black hole will pull a ray of light and cause its path to change.
A black hole’s gravity can cause a ray of light to gain gravity and attract objects.

Some fungi and insects benefit each other; the fungi protect the insects from predators and the insects spread spores for the fungi. This is an example of a mutualistic relationship.
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.

Explanation:
How many sperm cells are formed from an original cell in a Drosophila fruit fly at the conclusion of meiosis?
O A. two haploid sperm cells
O
B. two diploid sperm cells
O C. four haploid sperm cells
D. four diploid sperm cells
Answer:
Answer: Four sperm cells.
Explanation:
Explanation: Meiosis is is a cell division process that generates four haploid cells (gametes) from a single diploid germline cell.
In the drosophila fruit fly, four haploid sperm cells are produced from a single original parent cell. The germ cells undergo meiosis to form gametes. Thus, the correct option is C.
What is Meiosis?Meiosis is the reductional division through which four daughter cells are produced from a single parent cell. The gametes are produced from meiosis. The gametes produced from a diploid cell are haploid in the number of chromosomes in cells. Both male and female gametes undergo fertilization to form diploid zygote.
Meiosis is divided into two parts- Meiosis I and Meiosis II. Both the parts comprises of four phases- Prophase, Metaphase, Anaphase, and Telophase. The chromatids undergo crossing over with non-sister chromatids to form recombination in cells.
Therefore, the correct option is C.

Explain the mechanisms by which sex-linked
diseases are inherited.
Answer:

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.

There are different ranges in temperature. Why is this change different is because this shift in temperature is happening more quickly.
Why are temperature around the world different?There are a lot of factors affecting temperature such has latitude. Most times, the places closer to the Earth's equator are said to be far warmer than those near to the poles.
The recent rise in temperature is said to be due to a new forcing. here, the greenhouse gas emissions from human activity, is said to have driven atmospheric CO2 to its highest level.

How is water formed during the electron transport chain
Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.

What relationship exist between amino acid and protein?
Explanation:
When connected together by series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on other interactions (dashed lines) between its amino acid side chains.
Amino acids are the subunits or monomers of proteins i.e. proteins are made up of amino acids.
WHAT ARE PROTEINS?
Proteins are one of the four major biological molecules in nature. Proteins are polymeric compounds made up of long chains of structures called AMINO ACIDS. Amino acids come together in a chemical reaction called CONDENSATION REACTION to form complex protein molecules. Each amino acid is linked to one another by a covalent bond called PEPTIDE BOND. Peptide bond is a kind of covalent bond that links two amino acids together. It forms between the amino group (-NH2) of one amino acid and carboxyl group (-COO) of anotherHence, amino acids are monomeric units of protein molecules.

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.

Which of the following environmental factors would positively influence the survival and reproduction of only light peppered moths?
A.
A forest fire that burns down the trees.
B.
Laws that improve air quality and restrict pollution.
C.
Increasing the number of factories that burn coal into the air.
D.
A disease that infects the light peppered moths and not the dark.
Answer:
The correct answer is - option B. laws that improve air quality and restrict pollution.
Explanation:
The dark peppered moths were the adaption of the light peppered moths due to the change in the environmental condition of increased pollution that made tree bark dark in color and allows birds to easily prey on the light peppered moths.
This leads to natural selection and light moths become dark but the after Clean Air Act was that there was less pollution then there is less soot in the air, so trees were less black which result in the Light-colored moths would increase, and dark-colored moths would decrease.
