There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.
Answer: A. Environmental drivers plus genetic variation in the population result in natural selection
Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.
There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.

Write the overall reaction for cellular respiration.
Answer: Explanation: Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). ... C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
Explanation:
Answer:
cellular respiration is the process of extracting energy and is explained in 3 steps.
first step: the glucose is broken down in the cytoplasm, which is called glycolysis
second step: the pyruvate molecules are then transported into the mitochondria, the "powerhouse" of the cell
third step: The molecules are transformed chemically when it enters an electron transport chain. This allows the molecules to be turned into ATP.
Once you know this, the chemical reaction is one molecule of glucose (C6H12O6) and six molecules of oxygen (O2) yields six molecules of carbon dioxide (CO2) and six molecules of water (H2O).
C6H12O6 + 6O2 → 6CO2 + 6H2O
this creates ATP
Read this speech given by US Secretary of Defense Chuck Hagel on Veterans Day 2014. What is the purpose of the speech?
Every year, we set aside Veterans Day to honor all the men and women who’ve served our country in uniform. We celebrate veterans from generations past. We welcome a new generation of veterans home from war. And we thank our future veterans, still serving at home and abroad.
They are securing our nation through their engagement across the globe. Some are in West Africa, contributing to the global effort to stop the spread of Ebola. Some are in the Middle East, working closely with our coalition partners in the fight against ISIL. And some are in Afghanistan, where next month the United States will responsibly end the longest war in our history.
For our troops serving around the world today, and those transitioning out of the military, our obligations are only beginning. Taking care of them, and their families, is a sacred responsibility we must always uphold.
Let’s celebrate them by telling their stories. Let’s help those who need it, while supporting their strength and resilience. And let’s honor our veterans by creating new opportunities for them to contribute after their service, so they can continue making a difference in the world.
To all our veterans—thank you. Thank you for everything you’ve done for our country. You’re among the best our nation has to offer. God bless you and your families, and happy Veterans Day.

When you use the same histone protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (5 points) a. The histone protein has fewer basic amino acids than albumin. b. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Answer:
A. The histone protein has fewer basic amino acids than albumin
Note: The question is incomplete. The complete question is given below:
You use the Bradford (coomassie) assay to determine the concentration of a whey protein. You use bovine albumin as your standard. You determine the histone protein concentration to be 3 mg/ml. When you use the same whey protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (2 points) The histone protein has fewer basic amino acids than albumin. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Explanation:
The Bradford assay measures the concentration of proteins in a a protein sample using a color change that occurs from brown to blue when the protein in the sample binds to Coomassie dye. The Coomassie dye specifically binds to basic and aromatic amino acids in the protein. A standard curve is created using absorbance data from samples of proteins of known concentrations. The spectrophotometer is set to read at 595 nm in the Bradford assay as the peak absorbance of Coomassie Blue once bound to proteins occurs at 595 nm.
The higher the concentration of proteins, the higher the color intensity and the higher the absorbance values.
Since when bovine serum albumin was used as standard, the sample protein concentration was lesser than when the protein sample was used as standard, this means that the sample protein binds less to Coomassie dye as a standard thereby giving a higher sample protein concentration than the BSA standard. Therefore, the histone protein has fewer basic amino acids than albumin.

What is a ribososme?Ribosomes, also called Palad granules (after their discoverer George Palade, for their granular structure), are macromolecular machinery found in all cells that perform biological protein synthesis (mRNA translation).Ribosomes join amino acids in an order determined by the codons of the messenger RNA (mRNA) molecule to form a polypeptide chain. Ribosomes are composed of two major components, the large and small ribosomal subunits.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).Ribosomes and related molecules are also known as the translational apparatus.The ribosome is a ribonucleoprotein complex because it is composed of a complex of RNA and protein.Each ribosome is composed of smaller (30S) and larger (50S) building blocks called subunits.

between water molecules. The water molecules join together
through the process of_____
The cohesive forces of water
allows a thin film to form called____. This allows
water striders to be able to walk on top of water.
I NEED HELP NOWW
Answer:
1. Polar 2. Hydrogen bonding 3. Cohesion 4. Surface tension
Explanation:
1. Water is a polar molecules due to the presence of unbalanced charges in its covalent bond.
2. This unbalanced charges causes the molecules to be polar and thus form hydrogen bonds with nearby molecules due to their opposite charges. The hydrogen atom carries the positive charge while the oxygen atom carries the negative charge. The opposing charges thus causes hydrogen and oxygen atoms in nearby molecules to be attracted to each other.
3. This attraction of the water molecules to each other is called cohesion. Cohesion is the force of attraction between similar molecules and this force of attraction is called a cohesive force.
4. Since the water molecules are attracted to each other due to a cohesive force, this cohesive force causes a thin film to form called surface tension. Thus, surface tension is the ability of the surface of a liquid to resist external forces due to cohesive forces in its molecules and thus form a thin film.

Compare the vagina and the anus. How does the fact that the vagina has a mucous membrane lining and the anus does not affect these structures as sexual organs?
Answer:
Explanation:
The mucous membrane lining provides lubrication which allows the vagina to act as a sexual organ. Without this membrane lining, the skin would get dry which would create friction when involved in intercourse. This friction can cause damage such as membrane tearing and even bleeding or burns. The anus does not have the mucous membrane lining like the vagina does which affects it from being an effective sexual organ like the vagina.
