If the producers were removed, there will be no species introducing energy in the ecosystem. As the producers are responsible for obtaining energy from the sun or chemical sources in the first trophic level and the consumers need this energy (that's why they feed on the producers and on other consumers that have already feed on the producers' energy), without this energy the entire ecosystem would be affected, as the amount of energy in all of the trophic levels would continuously reduce untill there were no more energy for them to acquire and they wouldn't survive.
On the other hand, the decomposers are responsible for returning to the soil/air/water the nutrients that were used by the species after the individuals are dead. Without them, the soil, the air and the water would be lacking nutrients, and the living individuals would have problems as they need those nutrients to keep the flow of energy through the ecosystem.

Draw comic strip should include an example of transcription (DNA to mRNA) and an example of translation (mRNA to amino acid, and include tRNA) as well as the location of both in the cell.
Answers
We have to consider that the DNA is first transcribed into pre mRNA in the nucleus of the cell by the RNA polymerase. After this process, the non-coding fragments (introns) of the molecule are spliced by ribonucleoproteins (snRNP). Eventually, each end of the pre mRNA is modified, being a modified nucleotide named CAP joined to the 5' end, and a polyA (poly Adenine) tail at the 3' end before the now matured mRNA gets out of the nucleus to the cytoplasm.
At this point, the mRNA will be recognized by ribosomes, which will synthesize each group of three nucleotides (codons) into amino acids in a process called translation, by the action of tRNA, and finally joined into a new protein.
Note that A, P, and E are sites of the ribosomes, being A the position where first arrives the mRNA.

Which shows the correct path that energy flows through an ecosystem?A. Sun -> producers -> primary consumers -> carnivores -> decomposersB. Producers -> carnivores -> decomposers -> primary consumersC. Sun -> primary consumers -> producers -> decomposers -> carnivores
Answers
The energy from the sun is captured by plants through photosynthesis, a process in which the plants will produce their own food, what gives them the status of producers. Those producers then are eaten by consumers that eat plants, which are called primary consumers. The primary consumers can be, for example, small animals, which will be eaten then by larger animals, called carnivores because they consume meat. The carnivores will, at some point, die and decompose, and their energy will be then consumed by decomposers.
Therefore, the correct answer is A. Sun -> producers -> primary consumers -> carnivores -> decomposers.
Answer: A. Sun -> producers -> primary consumers -> carnivores -> decomposers.

A. Female condoms
B. Male condoms
C. Copper containing intrauterine device
D. Progesterone containing intrauterine device
E. Combined oral contraceptives
Answers
Answer:
E. combined oral contraceptives
Explanation:
Oral contraceptives will decrease a woman's risk of developing ovarian and endometrial cancer. The earlier, higher dose oral contraceptive pills have been linked to a slight increase in breast cancer, but not the most recent lower dose pills. Women who use oral contraceptive pills have a slightly higher risk of developing cervical intraepithelial neoplasia, but their risk of developing PID, endometriosis, benign breast changes and ectopic pregnancy are reduced. Both hypertension and thromboembolic disorders can be a potential side effect from using oral contraceptive pills. Condoms and intrauterine devices will not lower her risk of ovarian cancer.

Which of the following statements about diffusion is FALSE?
Question 39 options:
smaller surface area of the cell membrane increases the diffusion rate
small molecules travel much faster than larger molecules
a higher concentration gradient increase the diffusion rate
higher temperatures allow for molecules to move quickly across the cell membrane
Answers
Answer:
smaller surface area of the cell membrane increases the diffusion rate
Explanation:
Diffusion is the process by which molecules move from a region of high concentration to a region of low concentration until there is an even distribution. The rate at which diffusion occurs is dependent on certain factors as follows:
- Temperature: An increase in temperature increases the rate of diffusion because there is an increase in the kinetic energy of the molecules in response to temperature.
- Surface area of the cell: A cell with large surface area undergoes diffusion at a higher rate than a cell with small surface area.
- Concentration gradient: The difference in concentration of the molecule on each side of the membrane is the CONCENTRATION GRADIENT, which when increased also increases the rate of diffusion.
- Size of molecules: small molecules tend to travel faster than larger ones, hence, they diffuse faster.

A mutation of the proteolytic enzyme Trypsin (described in Section 6.1) results in a stable covalent bond between one of the catalytic amino acids of the protease and its protein substrate. Which of the following are probably true?
a. The enzyme would become inactive.
b. The enzyme and substrate would be stuck together.
c. The delta-G of the proteolysis reaction would change.
d. The rate of the catalyzed reaction would increase.
Answers
Answer:
b. The enzyme and substrate would be stuck together.
Explanation:
Enzymes are proteins whose active site binds to specific chemical reactants (i.e., substrates), thereby forming a complex that is similar to the interaction between a lock and its key. This active complex lowers the energy of the reaction and promotes a conformational change in the substrate to break down it into multiple products. When the enzyme contains mutations in its active site, the ability to bind the substrate is altered. In this case, the enzymatic reaction can't occur because the interaction enzyme-substrate doesn't produce an active complex.
In the process of mutation of a proteolytic enzyme, the enzyme and the substrate would be stuck together.
What is the process of mutation of a proteolytic enzyme?The process of mutation of a proteolytic enzyme is a ubiquitous and permanent post-translational alteration that involves the restricted and highly selective hydrolysis of a protein's peptide and isopeptide bonds by a protease.
We know that enzymes are proteins that have an activation site that binds to certain chemical reactant molecules (e.g substrates), generating a complex akin to the interaction of a lock and its key.
This active complex decreases the reaction's energy and induces a conformational shift in the chemical reactant molecule (substrate), therefore allowing it to be broken down into numerous products.
The capacity of the enzyme to interact with the substrate is changed and altered when it has mutations in its activation site.
Therefore, this enzymatic reaction cannot take place in this scenario due to the fact that the enzyme-substrate contact does not form an active complex.

Explain the reciprocal relationship between human society and limiting factors.
Answers
Answer:
A limiting factor is a situation or condition that determines the speed or growth of a certain biological or social process, due to the fact that only a limited amount of it is available.
Therefore, a limiting factor is one that places a limit on the development of a certain characteristic within society. A clear example within biology is the lack of drinking water sources, which is a limiting factor for the development of population settlements, as occurs in the Sahara.
Thus, the existence of limiting factors puts a brake on the unrestricted development of human society, conditioning its development to the adaptation of individuals to the natural conditions of the environment.
Possible Answer:
Human society makes modifications to the environment to suit its needs. Humans can live in large numbers in harsh environments that do not necessarily support the population because of these modifications. Humans cannot, however, change the fact that they are affected by limiting factors. They can change the limiting factors in a specific area, but are still influenced by limiting factors in a larger area, either by region, or globally. Food, water, and energy supplies are limited and will only support a certain human population size. If the human population exceeds this size than disease, famine, and other limiting factors will naturally limit the population size.
