1) Cetacea gives live birth to a very small number of offspring at one time and invest a great
amount of energy in parenting. Most fish, however, reproduce hundreds at one time and spend
very little time in parenting. Discuss the advantages and disadvantages of both methods.
There are two condition: -
1. Less offspring, and more parenting
2. More offspring and less parenting
Less children and more parenting have the advantage of requiring less energy for reproduction and more for parenting, which eliminates the possibility of infant death. The drawback is that this results in a relatively small number of progeny, who may be eliminated by the environment, enemies, or predators, causing disruption in population.
The benefit of having more children and doing less parenting is that there will be a huge amount of children generated who are capable of reproducing, which will ultimately lead to population expansion. The drawback of this situation is that there is no guarantee of survival because of the possibility of encountering predators, natural disasters, or other challenges.

Imagine you are exploring a new planet and discover a plant-like organism which does not have chloroplasts. Which of the
following statements would be TRUE about the organism?
O It may not be capable of photosynthesis.
O It still has all the appropriate organelles to photosynthesize like an earth-based plant.
O It uses different wavelengths to photosynthesize than earth-based plants.
O It does not store energy as glucose
Chlorophyll, a pigment found in chloroplasts, is what allows plants to prepare food through photosynthesis. There would not have been any plant life if there were no chloroplasts.
Chlorophyll, which is found in chloroplasts, traps light and aids in photosynthesis. Without chlorophyll, there would be no food, which would mean no life. We wouldn't have food if plants lacked chloroplasts since they couldn't use the sun's energy to stay alive. On the other hand, mammals would not have enough cellular energy and would not be able to exist without mitochondria. The process of photosynthesis is carried out by some plants that lack chloroplasts.

Please answer the following questions based on the titration curve:
1. From the plot, determine the number and types of titratable groups for the unknown amino acid.
2. Determine best you can the experimental pKa values for each titratable group from the plot
3. Determine best you can the molecular weight of your unknown amino acid from data obtained from
your plot.
4. Calculate the isoelectric point of your sample. a) What is the definition of isoelectric point? b)
Where would you find the isoelectric point on a titration curve?
5. What is the identity of your unknown amino acid? Justify your conclusion by comparing the
observed molecular weight and pKa values to those for all of the amino acid
Titration is a useful tool in the determination of amino acid side chains and the ionizable groups. There are two titratable groups for the unknown amino acid. These are α-COOH and α-NH₃⁺. The experimental pKa values for the groups are- pK₁ = 2.35 for α-COOH and pK₂ = 9.78 for α-NH₃⁺.
What is Isoelectric point?Amino acids are the organic compounds that contain both amino and carboxylic acid functional groups. Isoelectric point (pI) is the pH at which the net charge on an amino acid is zero. The isoelectric point of the given amino acid can be calculated by the formula:
pI = (pK1+pK2)/2 = (2.35+9.78)/2 = 6.065
Isoelectric point will be in the middle part of the curve in the buffer region. Buffer region is the section of curve between the initial point and the equivalence point.
The unknown acid would be glycine. The curve gas two dissociation steps- loss of H⁺ from the carboxyl group at low pKa value and gain of H⁺ by the amino group at high pKa value.

A. Recognize a problem
B. Form a hypothesis
C. Test the hypothesis with an experiment
D. Draw Conclusion
The correct answer is B. Form a hypothesis.
Since at least the 17th century, the scientific method has guided the growth of science. It is an empirical approach to information acquisition (with notable practitioners in previous centuries). Given that cognitive presumptions might skew how one understands the observation, it requires careful observation and the use of strong skepticism regarding what is observed. It entails developing hypotheses through induction based on these observations, statistically evaluating deductions taken from the hypotheses using experimental data, and then modifying (or removing) the hypotheses depending on the experimental results. These are scientific method principles, as opposed to a predetermined set of processes that apply to all scientific endeavors. An educated prediction as to what will occur throughout your experiment serves as the hypothesis.Variables will be used in your experiment.Therefore, the correct answer is B.

Describe how a hypothesis and a design are similar.
A hypothesis outlines your expectations for the results of your investigation. It is a speculative, untested response to your research question. You might need to develop a number of hypotheses for some research projects that speak to various facets of your research issue.
A hypothesis should be founded on accepted ideas and body of information; it shouldn't just be a wild guess. Additionally, it must be testable so that you can use scientific research techniques to either confirm or disprove it (such as experiments, observations and statistical analysis of data). A relationship between two or more variables is proposed by a hypothesis. Anything the researcher modifies or controls is referred to as an independent variable. An observation or measurement made by the researcher is a dependent variable.

Antibodies are a Y-shaped protein that are secreted by the immune system to identify and neutralize pathogens in vertebrates. Antibodies have an antigen binding site that allows for binding to surface proteins found on a specific pathogen, called antigens. All cells have identifying protein markers on the surface that specify whether it’s foreign or a part of the same organism. Some pathogens have the ability to alter their antigens, preventing antibodies from identifying them.
Which of the following arguments is BEST supported by this information?
A
The shape of an antigen allows for antibodies to identify the cell, indicating that the shape of the protein provides specificity.
B
The binding site of an antibody can be altered to accommodate more pathogens.

Dormancy is the period during which the organism's metabolism decreases to conserve energy. Hibernation is a type of dormancy expressed by animals. This adaptation is Hibernation.
What are dormancy and hibernation?
Dormancy is a period in the metabolism of different organisms, in which their growth, development, and physical activity get suspended for some time. The reduction in all metabolic activities allows the organism to conserve its energy.
Dormancy is closely related to environmental conditions and is considered an adaptation mechanism by which organisms respond to extreme conditions.
Hibernation is a type of dormancy, in which animals progressively decrease their metabolic rates, and body temperature is held a few degrees over the ambient temperature. During hibernation, all functions are reduced: cardiac rithm, respiration, renal function, etcetera.
Frogs, snakes, and lizards, among other cold-blooded animals, need to go through dormancy to survive extremely cold temperatures.
Notice that the dormancy term is commonly used in seeds when referring to the period before they germinate and the new plant emerges. This is another type of dormancy that relates especially to plants.
This type of adaptation is Hibernation (or animal Dormancy).
