Daniel was a prophet of God both to God's captive people and to all of the following gentile kings except:
Nebuchadnezzar
Darius
Xerxes
Belshazzar
Daniel was a prophet of God both to God's captive people and to all of the following gentile kings such as Nebuchadnezzar, Darius, and Belshazzar except Xerxes. Thus, the correct option is C.
Who was Daniel?Daniel is the main character of the Book of Hebrew Bible. According to the Hebrew Bible, Daniel was a noble Jewish of the Jerusalem, who was taken into captivity by the Nebuchadnezzar II of Babylon, who later serves the king and his successors with loyalty and ability until the time of the Persian king Cyrus, all the while remaining true to the God of Israel.
The consensus of one of the most modern scholars is that Daniel is not a historical figure according to the Bible and that the book is a cryptic allusion to the reign of the 2nd century BCE Hellenistic king Antiochus IV Epiphanes.
Daniel was a prophet of God and all the gentile kings like Nebuchadnezzar, Darius, and Belshazzar except Xerxes.
Therefore, the correct option is C.

Many Learners Perform Well In Grade 12 But still not accepted into Universities.Explain Two Reasons For This
Answer:
1. Confusion
2. Financial issue
Explanation:
1. The reason I say this is that many of them are not really sure about what they want they want to do in their later future making them a little confused on what to do.
2. It is a common issue which has taken away so many bright minds away from their future in helping the world and their individual community to prosper in different ways.
The reason why many students from grade 12 are not accepted in universities is that they may not be ready to pursue a given career or their parents may not be able to afford it.
Why are grade 12 students not accepted in universities?In the whole of North America, grade 12 is the senior class or the highest class in high school.
Some grade 12 students may not be admitted into university even though they performed well because;
Some of the students who have finished well in grade 12 do not yet have clear cut career orientations.Also, some of them may not have parents that can afford to send them to the university.Hence, a good performance in grade 12 do not guarantee university admission.

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).

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.

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.

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.
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.

1. which of the following organisms is not a strepsirrhines?
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.

Explanation:
Your first assignment is to provide information to the firm BigMoney Inc., a chemical producer in Kansas interested in using microbes to clean toxic spills (bioremediation). BigMoney Inc. has had a major spill of inorganic S that contaminated the soil around their plant. Scientists at BigMoney have developed mechanisms for removing H2S from soil, but have not found one for S. They want to know on a strictly theoretical basis (regardless of whether bacteria exist in nature that actually do these specific reactions) if there are any types of bacteria that could use S to give rise to H2S. (7 points total)
S ? H2S (-0.274)
a) is this an oxidation or reduction?
b) is S serving as an electron acceptor or donor?
c) Which of the following metabolisms (aerobic respiration, anaerobic respiration, aerobic chemolithotrophy and anaerobic chemolithotrophy) could be used to carry out this reaction? You can assume the reaction given above is either the initial oxidation reaction or the final reduction reaction. You must think about whether each of these metabolisms can oxidize or reduce inorganic materials. Remember, think strictly theoretically. Note, you must indicate ALL metabolisms that could be used. (1 point)
d) For each of the metabolisms that could be used, describe exactly how H2S will be formed providing the following information: (5 points)
Is the initial electron donor (from where are the electrons being taken) organic or inorganic?
Which of the pathways discussed in class (glycolysis, TCA, electron transport chain, chemolithotrophy, photosynthesis, and fermentation) will be used to get the electrons?
Is the final electron acceptor oxygen or not oxygen, and is it organic or inorganic?
Please provide a specific example of a half reaction (either initial oxidation or final reduction) that would work with the half reaction provided in this scenario, and briefly describe why it was chosen. Hint: your answer must consider the reduction potential of the electron acceptor compared to that of the electron donor and the half equation given must be either the donating or accepting reaction. Note: you may assume other molecules, both organic and inorganic, are present in the soil.
