Answer:
d. Pluripotency markers
Explanation:
Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.

Answer:
1. DNA identification by PCR
2. Forensic entomology
Explanation:
Polymerase Chain Reaction (PCR) is the most widely used technique in molecular biology to identify DNA samples, and it is a method regularly used in criminal cases. The PCR technique enables the amplification of specific genome regions by using a set of oligonucleotides (primers) that pair with the sequence of interest and a Taq polymerase that synthesizes DNA copies that are specific of the person to be identified. PCR reaction consists of several rounds of amplification in order to obtain sufficient DNA product to visualize it.
Forensic entomology is used in criminology to determine the time period between the discovery of a human body and the time that colonization by insects occurred, thereby providing an estimation of the post-mortem interval in human bodies. In addition, this technique can be used in abuse and other types of criminal cases because insect colonization also provides useful information about the nature of the decomposition processes in one crime scene.
Answer:
The DNA fingerprinting technique and development and comparison of physical fingerprints can be the methods used for the purpose of solving crimes and identification of missing person.
The DNA fingerprinting can be done from the physical evidences such as blood, sweat, hair, tissues, teeth and other material obtain at crime scene. These can be compared with the suspects, victim and missing persons so as to establish their identity.
The physical fingerprints can be developed on the scene of crime and compared with the requested specimen from suspect, victim and the missing person or in case of impersonation to establish the desired identity

Dependent variables and independent variables in an experiment are defined as the terms of cause and effect.
The variables are:
- The dependent variable is the concentrated lactic acid and NAD+.
- Control is the response of NAD+ and lactic acid in the absence of vitamin treatment.
In the given experiment, the dependent variable is the concentrated lactic acid and that of NAD+, whereas the control is the response of NAD+ and lactic acid in the absence of vitamin treatment.
The given experiment is about respiration in which the electrons from glycolysis and Krebs cycle are transmitted to the electron transport chain. In the electron transport chain, reduction of NAD+ into NADH takes place.
Thus, the variables in an experiment are used to study the hypothesize the results.
To know more about variables, refer to the following link:
Answer:
(a).concentrated lactic acid and that of NAD+.
(b).use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
Explanation:
To understand this question and be able to solve this question efficiently we have to understand the concept of "respiration''. But, the short and the most simple answer to the question above can be found in the first statement of the question.
The electron transport chain include the cycle that occurs during glycolysis, fermentation and the transformation of NAD+ to form NADH and vice versa.
In the research, the dependent variable is the concentrated lactic acid and that of NAD+.
In order to increase the validity of the experiment, the Researcher can make use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.

Common characteristics supporting the idea that the first land plants were related to green algae include All of the above. Thus, option "D" is correct.
Which algae is responsible for main supply of oxygen in the atmosphere?
The Green algae are responsible for the main supply of oxygen in the atmosphere. There are tiny organisms called cyanobacteria (or blue-green algae) which photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.
The waste product of cyanobacteria is the oxygen of the atmosphere.
Thus, option "D" is correct.

Which detail from the passage creates the most suspense for the reader?
“Minos, king of Crete, had made war upon Athens.”
“He had laid waste the fields and gardens round about Athens.”
“Then Aegeus, the king of Athens . . . went out to see King Minos and to treat with him.”
Answers
It is likely that the detail that creates the most suspense for the reader is "He [Minos] king of Crete, had made war upon Athens.”
What was the confrontation between Minos and Athenian ruler?
It is likely that the detail that creates the most suspense for the reader is "He [Minos] had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town."
This detail implies that the confrontation between Minos and the Athenian rulers will be violent and destructive, and the reader may be left wondering what will happen as a result. Additionally, the fact that Minos has already laid waste to the surrounding area and burned the merchant vessels in the harbor suggests that he is a formidable and potentially dangerous opponent, further increasing the suspense for the reader.
