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.

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 force creates the tides?
A. Solar Flares
B. Neptune’s gravitational force
C. Sun’s gravitational force
D. Moon’s gravitational force
Answer:
D.Moon's gravitational force.
Answer:
D) Moons gravitational force
Explanation:
Gravity and inertia act in opposition on the Earth's oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean's waters toward it, creating one bulge.
Therefore saying, the moons gravitational force.

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.

Can you explain why DNA must be replicated before mitosis and the role of helicase in DNA replication
Answer:
1. dna needs to be replicated before mitosis so that the parent cell has the same amount of genetic material as the parent cell once it has split.
2. helicase is an enzyme that is so dna can unwind.
Explanation:
the explanation is in the answer.
I hope this helps!
Answer:
DNA must be replicated before mitosis so that both identical daughter cells contain the same amount of genetic material as the parent cell once it has split in two. Helicase is an enzyme necessary at the initiation of DNA replication to unwind/unzip the DNA so that this process may begin.
Sarah is finishing a model drawing of a cell. She adds a membrane to the nucleus on her model. The nucleus of a cell has a membrane that isolates
material inside of it from the rest of the cell. Why does the nucleus need a membrane?
A.
The membrane helps the nucleus to create energy for the cell.
B.
The membrane helps the nucleus to create proteins for the cell.
C.
The membranes helps the nucleus to remove waste from the cell.
D.
The membrane helps the nucleus protect genetic material for the cell.
Answer:
C
Explanation:
a nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials such as nucleic acids and proteins, between the nucleus and the cytoplasm .

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.

D. It falls as melted snow and is caught on the grass.
E. it falls like a light rain and is caught on the grass.

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.

1. How will photosynthesis affect the dissolved oxygen levels in the
water?
Answer:
Vegetation- riparian vegetation directly affects dissolved oxygen by releasing oxygen into the water during photosynthesis. It indirectly affects dissolved oxygen concentrations because vegetation shading a stream may decrease water temperatures, and as temperature decreases dissolved, oxygen increases.
Hope this is fine for youHow 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.
