Oct4 is an embryonic stem cell specific transcription factor. ESCs grown in petri dishes are fed media that contain basic fibroblast growth factor (bFGF) which keeps the ESCs undifferentiated. They examine Oct4 mRNA levels in human ESCs (hESCs), hESCs with exogenous miR-223 (micro RNA 223), hESCs with exogenous miR-223 that do not have bFGF in the media, and hESCs without bFGF but with miR-223 inhibitor.Which technique would allow for measurement of Oct4 mRNA levels
Answers
Answer:
You can use the quantitative Reverse Transcription Polymerase Chain Reaction PCR (RT-qPCR) method in order to analyze the Oct4 mRNA level.
Explanation:
RT-PCR is the gold standard technique to analyze the expression levels of one particular messenger RNA (mRNA) molecule. In this technique, the total RNA is firstly extracted and transcribed into complementary DNA (cDNA). Subsequently, the gene sequence of interest is then amplified in a standard PCR technique that uses as control one or more genes in order to measure the relative expression levels of the target mRNA, in this case, for example, the Oct4 mRNA.

Describe how the components of a meal containing fried fish and toast bread will be processed as they move through the digestive system of man
Answers
Answer:
Explanation:
When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:
1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.
2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.
3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.
4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.
5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.
6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.
Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

A botanist scrapes off a flower of one plant and then uses it to pollinate the flower of another plant. What can be scientifically concluded about their offspring
Answers
The offspring resulting from pollinating a flower of one plant with the scraped-off flower of another plant will be genetically distinct from their parent (option c) .
When a botanist scrapes off a flower from one plant, it collects the pollen from that flower.
The botanist then uses the collected pollen to pollinate the flower of another plant, transferring the genetic material from one plant to another.
Pollination is the process by which pollen grains are transferred from the male reproductive organ (stamen) to the female reproductive organ (pistil) of a flower.
During pollination, the pollen carries the genetic information (DNA) of the plant it came from.
When the pollen reaches the stigma of the second plant's flower, it fertilizes the ovules and initiates the formation of seeds.
The seeds that develop from this cross-pollination will contain a combination of genetic material from both parent plants.
Due to the mixing of genetic material, the offspring will be genetically distinct from either parent.
The specific characteristics of the offspring will depend on the traits inherited from each parent.
Genetic recombination and variation occur during sexual reproduction, resulting in offspring that exhibit a range of genetic traits.
Therefore, based on the process of sexual reproduction and genetic mixing through pollination, it can be concluded that the offspring will be genetically distinct from their parent.
