Explanation:
The differentiated cell has specific transcription factors that are present in the cell and cause specific genes to be transcribed. Option E is the correct answer.
What is cell specification?Cell specification is the process by which a cell determines its fate. After specification, a cell's gene pattern changes. Some genes that are present in euchromatin regions are expressed, and as a result, this cell expresses specific proteins and RNA.
After the zygote is formed, it undergoes a cleavage process to form multiple cells by mitosis. The cells then specify and receive their fate, such as some converting into nervous cells, others into epithelial cells, and still others into blood cells.
This change in structure and function is due to the expression of special genes in DNA. Though all cells have the same genetic content, some genes are present in euchromatin regions and some genes are present in heterochromatin regions. Genes of euchromatin are expressed.
Hence, option E is the correct answer, as the cell produced specific transcription factors.

Bacterial DNA is a double-stranded helix that has to ___________ its strands during replication. The _______ of DNA strands at the replication fork creates twists farther down the helix that need to be ______ by DNA _______. Ciprofloxacin ______ this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Answer:
Bacterial DNA is a double-stranded helix that has to separate its strands during replication. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed by DNA gyrase. Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Explanation:
DNA which stands for deoxyribonucleic acid is the molecules that stores genetic information in most living organisms. For successive reproduction to take place as well as growth to occurs in organisms, the genetic information stored in the DNA must be copied into new cells. This is achieved through the process of DNA replication.
DNA is a double-stranded molecule that is helical in shape. For replication to occur, the double strands has to be separated so that the information stored within can be accessed and then copied. DNA helicases are enzymes which are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed otherwise, the DNA strands will break. The enzyme responsible for relaxation these twists is known as DNA gyrase. Thus, any drug like Ciprofloxacin than inhibits DNA gyrase will block the DNA replication process in bacteria thereby stopping the growth of the bacteria.
Bacterial DNA is a double-stranded helix that has to separate its strands
during replication. The unwinding of DNA strands at the replication fork
creates twists farther down the helix that need to be relaxed by DNA gyrase.
Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the
deadly bacteria from growing.
The antibiotic referred to as Ciprofloxacin acts on the DNA of the bacteria
and it does this by inhibiting the enzyme that is required for DNA
synthesis. This stops replication and the anthrax bacteria from growing and
forming new organisms.

A) Carbon won't be removed from the air.
B) Photosynthesis won't occur.
C) The turtles won't be able to breathe.
D) All of these are correct.

Answer:
The correct answer is - D. All of these are correct.
Explanation:
It is clear that the terrarium is sealed or not, if it is open to the outside environment or not. Considering it sealed and no outer interaction, then if a fake plant to this terrarium then there will be no photosynthesis will take place as there are no green plants to capture the sunlight and make glucose and no way to release oxygen for the other organisms.
If in this no green plants then the removal of CO2 will not be possible. Higher amount of carbon and without oxygen turtles would not be able to survive even though there is food for them.

Answer:
Do you have a list?
Explanation:
Ian is an 18-year-old gymnast training at a private gym with many other male and female gymnasts. he is competing at an advanced level and is likely to make the next Olympic team. Lately, he has found that some of his balance and strength moves on the rings and parallel bars have become more difficult. He has gone through a bit of a growth spurt and gained approximately 5 pounds over the last year. He suspects the weight gain is causing his performance difficulties. He decides to try a weight-loss program that will help him lose weight before his next big competition in 6 weeks. He is not sure how many calories to consume and therefore arbitrarily decides to eat 1,500 calories per day.
1. Which assessments are required to determine whether Ian needs to lose weight?
2. What type of diet and exercise plan would you recommend for Ian?
3. What additional concerns do you have for Ian's health and sport performance?
Answer:
Explanation:
(1.)
Assessments needed to reduce Ian’s body weight:
A weight-loss program should allow the loss of weight should be fat loss, and the increase of weight should be body muscle mass. Weight reduction should be accompanied by an acceptable exercise regimen (both strength and conditioning). A well-balanced diet with sufficient energy (calories), carbohydrates, protein, and fat should be part of every weight-loss regimen. Excessive exercise resulted in weight loss. Using anorexic medications, laxatives, insulin, diet tablets, stimulants, diuretics, dietary products, or any lawful or illicit drugs and/or nicotine should be banned at all levels.
(2)
type of Diet:
Every day, Ian must eat three meals and just a snack. A fiber-rich cereal with skim milk and fresh fruit can be a better way to start the day.
After that, have a bologna sandwich on the whole bread with fruit or a big vegetable-rich salad together with a small turkey sandwich in addition to a cup of skim milk for lunch.
Poultry hen should be served with potatoes (baked), mixed vegetables, and skim milk for dinner. An early workout snack of a small butter muffin or yogurt combined with cereal should also be included.
Exercise Plan:
i) Bodyweight fat recovery can be supported by proper and secure aerobic activity.
ii) The right kind of aerobic exercise is extremely beneficial for weight loss.
3. Gymnastics is a visually appealing discipline that necessitates speed, strength, and coordination. Most high-level gymnasts eat less than the recommended amount of calories and certain nutrients for their age and training load, according to dietary tests. Young gymnasts, in particular, must absorb enough energy and nutrients to satisfy the demands of growth, exercise, performance, and tissue conservation. Poor energy supply, disordered eating habits, and eating disorders are all factors that can damage a gymnast's long and short-term health. Some gymnasts cross the line into extreme, treatable eating disorders by dieting and using infective weight-loss strategies.
In light of these considerations, Ian should pay attention to his health and diet. Ian should limit his consumption of added sugar intake and increase his fiber intake to help him achieve his body fat targets. Gymnasts can consume at least 1.4–1.8 grams of carbohydrates each pound (3–4 g/kg) per day. Increased protein consumption helps to reduce the amount of muscle lost over a weight-loss cycle. Per day, gymnasts can eat 0.8–1.2 g/lb (1.8–2.7 g/kg) of protein.
Ian would be able to shed weight and prevent an eating disorder in this manner.
