Answers

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

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

Answers

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.

Explanation:

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.

Answers

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 =  1/16

Parent 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

                PW         Pw          pW         pw

    PW    PPWW    PPWw     PpWW   PpWw

    Pw     PPWw    PPww      PpWw   Ppww

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.

Answers

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.

In 3–5 sentences, compare and contrast the flow of matter and energy in each

trophic level for land-based ecosystems and marine ecosystems. How and why

are they similar, and how and why are they different? (4 points)

Answers

Answer:There is a fundamental difference in the way energy and matter flows through an ecosystem.Matter flows through the ecosystem in the form of the non-living nutrients essential to living organisms. When a living organism dies, nutrients are released back into the soil. These nutrients then are absorbed by plants, which are eaten by the herbivores. Matter, once again, is passed on. The herbivore is eaten by a carnivore (and matter is yet again transferred therein). Ultimately, when the carnivore dies, matter is returned back to the soil by the decomposers and the cycle repeats. So you see, matter is recycled in the ecosystem.Unlike matter, energy is not recycled through the system. A part of the energy is lost at each stage.

in what ways can overpopulation be beneficial to differential reproductive success?

Answers

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.
