In this activity, students learn about the Human Genome Project. They do an interactive Web activity which simulates the process scientists use to determine the sequence of chromosomal DNA bases. Then they learn how two teams of scientists raced to decode the human genome. Next they explore a stretch of sequenced DNA on the Web to learn about the function of different sections of DNA code. They learn how knowledge of the human genome is being applied to medicine. They also learn about genetic variation among humans and between humans and other species. Finally, they assess what they have learned about the Human Genome Project by playing a game of Jeopardy.

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.

Multiple Choice
Which of the following is typical of aerobic respiration?
decreases a plant’s weight
contains two stages, glycolysis and fermentation
produces methane as a byproduct
produces little energy
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".

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.

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.

How are rivers made ?
Answer:
Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land - meandering - or going around objects such as hills or large rocks.
Explanation:
Hope this helps!
Answer:
A river is created when water moves from higher elevation to lower elevation. It usually goes downhill, and can join with other rivers. The river ends when it flows into an ocean.

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.
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.
