7. Heat tolerance in flies is a heritable trait. The variation in heat tolerance across a population of flies can be measured by subjecting groups of 100 flies to different temperatures and measuring the percentage of flies that survive. The following graph shows the distribution of heat tolerance across one species of fly living in hot desert regions of Africa. Predict what will happen to the size of this population and its allele frequency if a massive heat wave descends on the area in the future, bringing daily temperatures to 42°C and lasting several months of time.
Answers
All flies that can't tolerate 42°F will die. Only high-temperature-tolerant alleles are handed down.
'This is further explained below.
What are alleles?Generally, One of two or more variants of a DNA sequence (either a single base or a segment of bases) at a specific position within the genome is known as an allele.
In conclusion, All of the flies in the population that are unable to withstand temperatures higher than 42 degrees Fahrenheit will perish. Only those alleles that are responsible for high-temperature tolerance will be passed down to subsequent generations.
The populace will get used to the heat.
The survival curve will begin to ascend after a few months have passed.

What is structure and function?The structure of a biological organism refers to the arrangement or organization of parts to form an organ, system, or living thing.
The structure of an organism determines the adaptation and survival of that organism in its natural environment because these structures perform functions that are germane to its survival.

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
Answers
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.

Describe how a hypothesis and a design are similar.
Answers
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.
C
Antibodies must be a complex protein because it is only found in vertebrates.

I need a short answer. Please hurry up
Answers
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).

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.

Answers
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.
