Explanation:
Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules is immunoglobulin G (IgG). Two heavy chains and two light chains form one IgG molecule. Classify each statement as describing the heavy chains, light chains, or both chains of IgG
a. form the antigen-binding site
b. contain multiple variable domains
c. are found in the Fab fragment
d. are found in the FC fragment
e. contain only one constant domain
f. contain multiple constant domains
g. contain only one variable domain
Answer and Explanation:
a. form the antigen-binding site ⇒ both chains
The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.
b. contain multiple variable domains ⇒ none
Both chains - light and heavy - contain only one variable domain (VL and VH).
c. are found in the Fab fragment ⇒ both chains
The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.
d. are found in the FC fragment ⇒ heavy chains
The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.
e. contain only one constant domain ⇒ light chains
Each light chain contains one variable domain (VL) and one constant domain (CL).
f. contain multiple constant domains ⇒ heavy chains
Each heavy chain contains three constant domains: CH¹, CH² and CH³.
g. contain only one variable domain ⇒ both chains
Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.

The California Mussel ( Mytilus californianus ) is the natural prey of the shore crab ( Carcinus maenas ). Study the graph above. Why would a crab adapt to having larger claws according to the graph?
a. Larger claws would help the crab camouflage in the rocks so the mussels won’t see them.
b. Larger claws would help the crab swim fast in a rough current toward where the mussels are hiding.
c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
d. Larger claws would scare away the mussels with thicker shells causing the crabs to choose a new food source.
Answer:
The correct answer is - c. Larger claws would help the crab crack open the shells of the mussels so the crab can eat them.
Explanation:
The graph (attached) states that the two variables size of claws of the crabs depends on the thickness of the shell of mussels. With the increase in the thickness of the shell of the mussels the size of the claws of crabs also increases and becomes larger.
The most likely explanation of this change would be adapting according to the change in the shell of the crab as they require to crack their shell to eat them as mussels are the primary food source of these crabs.

Dr Mano is a researcher who thinks that the poor performance of the students at his school is due to excessive alcohol intake. What scientific steps can he take to best study his assumptions
Answer:
to design an experiment aimed at testing the null hypothesis. Finally, it is required to apply a statistical measure in order to reject or accept the null hypothesis
Explanations:
The scientific method consists in the first place in posing a question that can be used to explain an observation from the real world. This question needs to be subsequently explained by a working hypothesis. In this case, the working hypothesis may be "the poor performance of the students is associated with alcohol intake". Then, it is required to design an experiment in order to confirm or reject the null hypothesis. In this case, the null hypothesis would state that there is no relationship between both groups. The further experiment would consist of testing the performance of the students that consume alcohol versus students that don't consume alcohol. Finally, the results obtained from the experiment must be analyzed by using a statistical measure such as, for example, the p-value, which enables to accept/reject the null hypothesis by assessing the significance level of the results.
According to the endosymbiotic theory, large prokaryotic cells may have
engulfed smaller prokaryotic cells over 1.5 billion years ago. If the smaller
cells survived, the larger cells may have eventually evolved into eukaryotic
cells.
How would you describe the relationship between the original prokaryotic
cells?
A. Specialized cells in a single organism
B. Predator-prey
C. Parent-offspring
D. Parasite-host
Answer: b
Explanation:
Predator-prey is the kind of relationship the original prokaryotic cell have.
This theory explains the origin of eukaryotic cells from prokaryotic cells.Mitochondria and chloroplast are the leading example that support the theory.What is endosymbiotic theory?It states that eukaryotes arose as a result of a fusion of archean cells with bacteria.The archean engulfed but do not eat an ancient, aerobic bacterial cell.To know more about Evolution theories here

Explain this diagram?????????
Answer:
the diagram explains the process of DNA digestion and DNA ligation, which is usually used in molecular cloning techniques
Explanation:
Molecular cloning can be defined as the process used to synthesize multiple copies of a particular DNA fragment. Molecular cloning requires the insertion of a foreign DNA fragment into an appropriate vector (e.g., a plasmid) through the action of specific enzymes that serve to cut and ligate DNA fragments. DNA digestion and DNA ligation use specific restriction enzymes and DNA ligases, respectively, in order to insert the foreign DNA fragment. For this purpose, restriction enzymes that generate single-stranded overhangs are preferred to create sticky ends which bind by complementary base pairing. Subsequently, a DNA ligase enzyme joins the DNA fragments together in order to create recombinant DNA molecules. DNA Ligation is often achieved by using a specific T4 DNA ligase, while there are many restriction enzymes that generate sticky-ends (e.g., BamHI, EcoRI, BaI228I, etc).

Which option identifies the kind of food represented in the following scenario?
The Bergman family has orchards all around town and they sell their fruit to several grocery stores and carryouts in the region.
packaged and processed
ready-to-eat
processed to preserve
minimally processed
Answer:
Minimally processed
Explanation:
Foods are said to be minimally processed when they undergo a little treatment so as to preserve them. These treatments might involve the application of heat, drying, and refrigeration so as to preserve them before consumption. Most fresh-cut fruits, vegetables, grains, legumes, dairy products, etc., fall under this range.
These kind of foods still contain a good amount of their nutrients as their original content are not lost due to excessive processing.
1.Explain the nature of social science in contrast with the nature of natural science ?
2. What are the social sciences and why is it important to study the fuctioning of human society?
Answer:
1-One of the major differences between the two is that humanities involve a more critical and analytical approach whereas social sciences deal with more of a scientific approach. ... As there is a scientific approach to social sciences, it is considered to be a branch of study in between humanities and natural sciences.
2-Social science examines the relationships between individuals and societies, as well as the development and operation of societies, rather than studying the physical world. These academic disciplines rely more heavily on interpretation and qualitative research methodologies. ... Political science.
Sociology.The societal behavior is studied and analyzed to achieve broad goals. Social research also contributes to societal development by increasing creativity and innovation. The new idea leads to the up-gradation of society. Focusing on research enhances the knowledge thereby giving more power to the society.

Explain the feedback mechanisms that control ventilation and circulation to include
the pacemaker of the heart.
It should be noted that the homeostatic feedback mechanisms that are important to regulate the ventilatory pattern of respiration involves the medulla and the pons.
Homeostatic feedback mechanisms.The pons are divided into two groups. Firstly, the pneumotaxic center sends signals that inhibit inspiration as it limits the activity of the phrenic nerve. Due to this, the signals of the apneustic center and the tidal volume decreases.
Secondly, the apneustic center signals inspiration for deep and long breaths and controls the intensity of breathing. The stretch receptors of the pulmonary muscles inhibit the apneustic center, therefore, it increases tidal volume.
Also, the medulla has two functional regions as well which are the ventral respiratory compartment, that stimulates expiratory movements, and the dorsal respiratory region that triggers inspiratory movements.
