To protect endangered species from becoming extinct, it’s highly recommended to raise the animals in protected areas such as zoos and wildlife sanctuaries. Although this step could protect them, what challenges do the animals face when these methods are used?
Zoos might help in protecting endangered species from extinction but trapping and keep them in unnatural environment is bad for their health as they limited space to roam around which leads to shorter life expectancy at times.
Challenges of animals in zoo :-Zoos are problematic from ethical point of view. Animals living in unnatural environment shows alteration in their behavior and such conditions may develop serious mental issues in them. Many times staff in wildlife sanctuaries aren't trained this leads to lack of individual treatment of animal. Most of the zoos doesn't really care about animals they use animals for profitable purposes. Zoos might not able to protect endangered species if the conditions are poor there too.

In 1953, Miller and Urey constructed an experiment that attempted to mimic the conditions leading to the formation of biomolecules on early Earth.
Part A: Construct a hypothesis statement that Miller and Urey might have made prior to conducting their experiment. Use an “if, then” format to write your statement. (1 point)
Part B: Describe in detail their experiment. Include what they used to simulate the conditions of early Earth, and what their results were. (3 points)
Answer:
A// If early conditions of primeval earth had ammonia, methane, hydrogen in its atmosphere, then it is possible that amino acids such as glycine, α-alanine, and β-alanine may have been spontaneously formed from chemical reactions spurred by energy from lightning.
Their hypothesis was that the early conditions of primeval earth favored the spontaneous formation of organic molecules, from inorganic precursors, that may have been the origin of life. This theory is called abiogenesis.
B//Miller Urey put methane, ammonia, hydrogen gases in a glass flask and a pool of water at the bottom of the glass flask. The flask was heated moderately to simulate the hot conditions then.

In a series of experiments, Griffith infected mice with nonvirulent R-strain bacteria and highly virulent S-strain bacteria. Heat-killed S bacteria were nonvirulent. However, the nonvirulent heat-killed S bacteria and the nonvirulent R bacteria together produced a virulent mixture. What did this demonstrate?
A. The molecules present on the outside of bacteria determine whether it's virulent or nonvirulent.
B. A transforming principle in the S bacteria allowed the nonvirulent R strain to become virulent.
C. The translation of proteins, carbohydrates, lipids, and DNA is important in determining bacterial virulence.
D. The S-strain bacteria had not been killed completely.
Answer:
The correct answer is B.A transforming principle in the S bacteria allowed the nonvirulent R strain to become virulent.
Explanation:
In the transformation experiments, conducted by Fredrick Griffith in 1928, he observed that heat-killed S-strain bacteria injected into mice did not kill them. When he injected a mixture of heat-killed S and live R-bacteria, the mice died. He concluded that the R-strain bacteria had somehow been transformed by the heat-killed S-strain bacteria. This occurred perhaps due to absorption of some transforming principal or substance by rough type bacteria from heat killed smooth bacteria. It had enabled the R-strain to synthesize a smooth polysaccharide coat and become virulent. This must be due to the transfer of the genetic material. However, the biochemical nature of genetic material was defined not from his experiments.
Answer:
the correct answer is :
B. ( A transforming principle in the S bacteria allowed the nonvirulent R strain to become virulent.)
Explanation:
According to Griffith's experiment, he used two strains of (Streptococcus pneumoniae ) which is bacteria infect mice causing pneumonia.
First strain: type |||-S (Smooth) bacteria, this bacteria is virulent, it has the ability to kill mice because it covers itself with smooth polysaccharide capsule that resist the immune system of mice, and this ability is according to the genetic traits inside its DNA.
Second strain: type ||-R (Rough) bacteria, this bacteria is non-virulent, it doesn't have this protective capsule so the immune system can resist it and it can't kill the mice on their own.
Steps of experiment :
Griffith killed the |||-S. by heat The remains of killed |||-S where added to the ||-R. bacteria He injected the mice with this mixture of ( heat-killed |||-S and ||-R )Observation:
The mice all died, However the virulent |||-S strain bacteria killed by heat
Conclusion:
The DNA of the |||-S strain bacteria survived the heat and transformed to ||-R, this means somehow, type |||-S bacteria still alive inside the type ||-R.This process called transforming principle, that allowed the nonvirulent R strain to become virulent.Animals have a variety of adaptations,including trachea and gills, which allow this key process to occur. Which provides the molecules necessary for cellular respiration and efficient ATP synthesis?
Answer:
Gas exchange
Explanation:
Trachea and gills are part of the respiratory system in organisms. These structures serve in gas exchange. The process of gas exchange removes carbon dioxide and allows oxygen gas to enter the body.
Aerobic cellular respiration is the efficient process of ATP synthesis as it produces the maximum number of ATPs by complete oxidation of nutrients. The process of aerobic cellular respiration needs the presence of oxygen.
Hence, Animals have a variety of adaptations, including trachea and gills, which allow gas exchange to occur. Gas exchange provides the oxygen necessary for cellular respiration and efficient ATP synthesis.

There is a liquid capsule inside a cup full of liquid. The cup full of liquid has salt in it and the liquid capsule has no salt in it. In which direction will the solvent flow? A. The salt does not have to move B. From the capsule to the larger cup C. Equally between the capsule and the cup D. From the larger cup to the capsule
Because of permeation, the salt will flow equally between the capsule and the larger cup in its quantity.
Hope this helps!
Answer:
The correct answer will be option- D.
Explanation:
The movement of solute, as well as solvent particles, depends on the concentration gradient of solute particles. The permeability of the membrane allows the movement of solute particles from higher concentration to lower concentration through osmosis.
In the given question, the capsule contains low solute concentration while cup water contains high solute concentration. As the solute particles move from the low concentration (capsule) to high concentration (cup water) therefore the water will move from the cup water to the capsule.
Thus, option-D is the correct answer.

What's the waste product of electrons and pyruvate combining in fermentation?
Answer:
Lactate
Explanation:
Under the conditions of oxygen scarcity, pyruvate does not enter the Kreb's cycle in the form of acetyl CoA. Rather pyruvate is reduced into lactate by accepting the electrons from NADH. Reduction of pyruvate and oxidation of NADH form lactate and NAD+. The process is called lactic acid fermentation.
Here, the NAD+ enter the glycolysis to continue the energy production while lactate is a waste product.
The function of the ciliary escalator is to
The ciliary escalator removes foreign particles and mucus from the respiratory system.
It is a respiratory tract process that aids in the removal of inhaled particles and mucus from the airways.
The ciliary escalator is made up of cilia, which are small hair-like structures that line the respiratory epithelium.
The cilia beat in unison, resulting in a wave-like action. Mucus, trapped particles, and bacteria are moved upward, away from the lungs, by this action.
Thus, by promoting the evacuation of undesirable particles and mucus, the ciliary escalator plays an important function in maintaining the cleanliness and health of the respiratory system.

What type of bonds link individual amino acids together?
Answer:
peptide bonds
Explanation:
Amino acids are linked together by peptide bonds. A peptide bond is formed in a condensation reaction between the amine (-NH2) and carboxyl (-COOH) groups of two amino acids, releasing a molecule of water. This process repeats to form a protein.
Explanation:Amino acids are linked together through particular types of bonds known as peptide bonds. In the process of protein formation, each amino acid is brought together with the next through a successive series of these bonds. Essentially, the amine group (-NH2) of one amino acid and the carboxyl group (-COOH) of a second amino acid gets connected in a condensation reaction and forms a peptide bond. In this process, a molecule of water is released.
Example
For example, if you are trying to link the amino acid glycine with another amino acid, like alanine, a peptide bond would form between the carboxyl group of glycine and the amine group of alanine. This results in the creation of a short protein chain or peptide.
