Answer:
Intron is essential for coding of proteins and hence it is present in the mRNA of Eukaryotes
Explanation:
Intron are important for coding proteins. In eukaryotic cell, the mRNA has introns and these introns are removed by encoding proteins from mRNA with a right sequence. Thus, introns are essential to encode DNA, RNA, protein etc, and they take partly important roles during encoding of mRNA to higher forms of molecules.

How does RNA polymerase know where to start and stop making a strand of RNA?
Answer:
Each gene has a beginning and an end. At the beginning of each gene is a similar sequence that tells the RNA polymerase to start working. The same is true at the end of each gene where a specific sequence tells the RNA polymerase to stop transcription

Land plants evolved long before any animals appeared on Earth. When they came onto land, they needed ways to keep from losing water, to reach the sun, and to produce oxygen. They started to convert the atmosphere from carbon dioxide to oxygen. Which of these is believed to be the common ancestor of land plants?
A. oak trees, because they are the dominant species in many areas
B. rose bushes, because they produce a sweet-smelling aroma

What is metamorphosis?? Hlw guys gøød Evening....
Answer:
a big change in a insect is called a metamorphosis
Example
tadpole will turn into frog= big change
[ METAMORPHOSIS ]
Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
Metamorphosis is divided into two types, namely:

Which courses should Don take in high school if he wants to pursue a degree and career in molecular biology? O anatomy and neurobiology O immunology and genetics O history and communications O physics and trigonometry
Answer:
anatomy and neurobiology
Explanation:
Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.
Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.
A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.
You place a cell in a solution that contains 12 more water molecules than the inside of the cell. How will you know when the cell reaches equilibrium?
Answer:
B
Explanation:
the water molecules will stop moving across the
cell membrane because the cell membrane has
the same amount of water as in the solution.
This process is called osmosis

Where does haemoglobin become oxyhaemoglobin?
Answer:
Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs.

1. What is the major goal of cellular respiration?
A.Reduce NAD+
B.Supply cell with fixed carbon
C.Produce ATP
D.Generate 02
Answer:
The primary “goal” of Cellular Respiration is to harvest energy from glucose and other energy-rich carbon- based molecules and use it to make ATP, which is the universal energy molecule.
 Which statement about the cells of organisms is accurate?

Materials are able to move across a cell membrane through one of two methods: active transport or passive transport. What is the difference between the two?
A
Active transport requires the cell to form vesicles, while passive transport requires the use of membrane pumps.
B
Active transport requires the cell to expend energy, while passive transport does not.
C
Active transport is the only form of transport that requires the use of protein carriers.
D
Passive transport is the only form of transport that requires the use of protein carriers.
Answer:
(B) Active transport requires the cell to expend energy, while passive transport does not

How did the CT enterography and the technetium scan lead to the correct diagnosis?
Answer: hope it helps..
Explanation: CT enterography is a new non-invasive imaging technique that offers superior small bowel visualisation compared with standard abdomino-pelvic CT, and provides complementary diagnostic information to capsule endoscopy and MRI enterography. CT enterography is well tolerated by patients and enables accurate, efficient assessment of pathology arising from the small bowel wall or surrounding organs. This article reviews the clinical role of CT enterography, and offers practical tips for optimising technique and accurate interpretation.
