In addition to greenhouse gases, what other evidence do scientists
collect from glaciers that provides information about the climate?
where do we find the most gases in the atmosphere.
Answer: The most gas in the atmosphere is nitrogen, with oxygen second. Argon, an inert gas, is the third most abundant gas in the atmosphere.
Where are most gases found in the atmosphere?
Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

Explanation:
Animals and plants use the chemical energy stored carbohydrates to fuel their own life processes, ultimately breaking down these carbohydrates into carbon dioxide, water, and heat in a process called aerobic respiration. The heat that is released from aerobic respiration dissipates into the environment. From this information, which of the examples of kinetic energy are:______
Answer:
A good example happens during the breakdown of food particles.
Explanation:
The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.
What kinds of characters can you use to create a data matrix for estimating phylogenetic trees?
a. any heritable trait.
b. any morphological trait.
c. any molecular trait.
d. any measurable trait.
Answer: The correct option is A
any heritable trait
Explanation:
This is because phylogenetic tree is a diagram that show or indicate the evolutionary relationships between several organisms from a descent or that have common anscetors which is based on the differences or similarities of there phenotypic traits or physically expressed inheritable traits.
Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.
Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Goats can either be polled or horned. The pulled, or no horn, trait (P) is dominant to the horned (p) trait. Another trait in goats are wattles, which are hair covered structures on their necks. Even though most goats do not have wattles, having wattles (W) is dominant to not having wattles (w). A breeder crosses a polled, wattled male goat with a polled, wattled female goat. Some of the offspring have horns and no wattles. Perform a cross of the parental genotypes to find the phenotypic ratios of the offspring.
Answer:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
Explanation:
Pulled = P, Horned = p
Wattled = W, no wattle = w
Polled, wattle goats = P_W_
Since they produced offspring with horns and no wattles (ppww), it means both parents have the recessive allele for each trait. Hence, they are both heterozygotes with PpWw as genotypes.
PpWw x PpWw
Genotypes ratio of the offspring:
P_W_ - 9/16
P_ww - 3/16
ppW_ - 3/16
ppww - 1/16
Phenotype ratio of the offspring:
Pulled and wattled = 9/16
Pulled and no wattle = 3/16
horned and wattled = 3/16
horned and no wattle = 1/16
(See the attached image for the Punnet's square)
Some alleles of a gene are dominant to others masking the effect this other alleles.
The polled, or no horn, trait (P) is dominant to the horned (p) trait.
Having wattles (W) is dominant to not having wattles (w).
A breeder crosses a polled, wattled male goat with a polled, wattled female goat.
The phenotypic and genotypic ratios would be
Polled and wattled = P_W_ = 9/16Polled with no wattle = P_ww = 3/16horned and wattled = ppW_ = 3/16horned with no wattle = pwpw = 1/16Parent genotype --- polled, wattled male and female goat -- P_W_
As the cross produced offspring with horns and no wattles (ppww), it shows both parents have the recessive allele for each trait.
Hence, they are both heterozygotes with PpWw for the traits.
Parent genotypes: PpWw x PpWw
PW Pw pW pw PW Pw pW pw

Think about the podcast that you listened to in the Lesson 2.01 Introduction. Write a one-paragraph (using complete sentences) description of the experiment that was performed on these two women. Be sure to include the following: Why was the experiment conducted? What was done to the two women in order to conduct the experiment? What conclusions could be made from this experiment? Why do you think that experiments like this are no longer performed?
Explanation:
The experiment was conducted with the purpose of understanding what makes us "who we really are"; our environment or genetics?
The two women, Paula Bernstein and Elyse Schein identical twins were separated from each other at birth and only got to be reunited when they turned age 35.
"It's undeniable that genetics play a huge role," says Paula. This makes us concludes that genetics still play a role in determining who really are.
Such experiments are no longer performed today because there are legal restrictions put in place against such actions, including the ethical issues it created.
Do green leaves absorb the maximum amount of light? If not, what color of leaf would

Answer:
Introduction
Cellular respiration is one of the most elegant, majestic, and fascinating metabolic pathways on earth. At the same time, it’s also one of the most complicated. When I learned about it for the first time, I felt like I had tripped and fallen into a can of organic-chemistry-flavored alphabet soup!
Luckily, cellular respiration is not so scary once you get to know it. Let's start by looking at cellular respiration at a high level, walking through the four major stages and tracing how they connect up to one another.
Steps of cellular respiration
Overview of the steps of cellular respiration.
1. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made. These reactions take place in the cytosol.
2. Pyruvate oxidation. Pyruvate travels into the mitochondrial matrix and is converted to a two-carbon molecule bound to coenzyme A, called acetyl CoA. Carbon dioxide is released and NADH is made.
3. Citric acid cycle. The acetyl CoA combines with a four-carbon molecule and goes through a cycle of reactions, ultimately regenerating the four-carbon starting molecule. ATP (or, in some cases, GTP), NADH, and FADH_2 are made, and carbon dioxide is released. These reactions take place in the mitochondrial matrix.
4. Oxidative phosphorylation. The NADH and FADH_2 produced in other steps deposit their electrons in the electron transport chain in the inner mitochondrial membrane. As electrons move down the chain, energy is released and used to pump protons out of the matrix and into the intermembrane space, forming a gradient. The protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain by electron carriers \text{NAD}^+NAD

Explanation:
Central Asia is where middle-Eastern Islamic culture meets Russian Soviet culture. The countries of Central Asia were once the center of multiple nomadic empires and tribes, including the Scythians, Mongols, and Turks. This had a big influence on the traditions and cultures of many Central Asian countries to this day.
Why is Glycolysis also known as Alcoholic or lactic acid Fermentation?
Answer:
In lactic acid fermentation, pyruvate from glycolysis changes to lactic acid. This type of fermentation is carried out by the bacteria in yogurt, and by your own muscle cells. In alcoholic fermentation, pyruvate changes to alcohol and carbon dioxide. This type of fermentation is carried out by yeasts and some bacteria.

Mutations result in changes to genotype that can result in changes in phenotype. Explain how a mutation causes a change in the genotype of an organism AND may result in a change in the phenotype of an organism.
Answer:
A mutation can alter the structure/function of a particular protein, thereby also altering the phenotype resulting from this new variant
Explanation:
A mutation can be defined as a genetic change in the genome of an organism. Some mutations are capable of modifying the expression and/or structure of the proteins, while other mutations (known as silent mutations) have no effect on the resulting proteins. When mutations occur within the gene region encoding a protein (i.e., exons), they are potentially capable of producing a faulty protein. For example, a mutation can alter the Open Reading Frame (ORF) of the resulting protein, thereby inactivating it. The mutations that alter the structure and/or function of the protein can also alter the resulting phenotype associated with the expression of this protein. For example, a mutation within a gene that encodes a key enzyme can potentially alter the binding site of the protein, so the resulting mutated enzyme cannot bind to the substrate anymore. In consequence, this mutation alters the phenotype of the individual who is not more able to carry out the metabolic reaction catalyzed by the faulty enzyme.

John Terborgh, tropical ecologist at Duke University, asserts that in order to save tropical forests, citizens of industrial nations are going to have to pay developing countries. Do you agree
Answer:
I do agree
Explanation:
As a personal opinion, I do agree with this statement. Citizens of developing countries use these rain forests for many reasons. One of which is for survival they cut down and use what they need in order to gather the resources that they need and build their habitats. This goes slowly destroying the rainforests. The other reason is that these citizens many times sell the rights to the rainforest land to mining companies that ultimately destroy the rainforest for its resources. The only way to prevent both of these from happening is by paying these developing countries to protect the rainforest instead of profiting from it.
in what ways can overpopulation be beneficial to differential reproductive success?
Answer:
Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.
Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.
