What do all vectors and scalars have?

Biology
1 answer:
gogolik [260]3 years ago
6 0

Answer:

D. magnitude

Explanation:

Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.

A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."

Both scalars and vectors have magnitude.

The epiglottis is pushed downward and the larynx is lifted up to meet it when we swallow. True False
Alex17521 [72]

Answer:

The correct answer is true.

Explanation:

Swallowing of food is the process of passing the food from the mouth to the stomach through the way of the throat (pharynx) and esophagus. This process takes place in three stages:  oral, pharyngeal, and esophageal stages  

During the pharyngeal stage, epiglottis which is a leaf-shaped flap of cartilage located at top of the larynx (a muscular organ forming voice box) perform functions in response to the swallowed food as the larynx lift up or rises inside the neck to close the epiglottis while the epiglottis moves downward to cover it, providing more airway protection.

Thus, true is the correct answer.

Formation of an RNA hairpin cannot be the sole factor in the termination of transcription in prokaryotes. Explain why.
Bas_tet [7]

Answer:

As the transcription process proceeds, a variety of secondary structures forms by the nascent RNA. t takes place due to the fact that portions of the transcript as complementary base pairs form.

The transcript could be pause but terminate, the hairpin loop causes RNA Pol to pause. There are two different ways to terminate transcription in prokaryotes

- intrinsic termination: in this no external factors required

- Rho protein termination: binds to end of msg and moves along by ATP hydrolysis to catch up (rho is faster)

Based on the current research progress, in the future, in which direction might liposomes break through in the field of food?
Darya [45]

Answer:

1) Through the intersection with physical chemistry, microbiology, pharmacokinetics and other disciplines, the relationship between food grade liposomes and other components, liposome structure and functional characteristics is established, which brings new opportunities for the development of more and newer food delivery systems.

2) To study the structural integrity and release kinetics of food grade liposomes in gastrointestinal tract digestion of different populations, overcome the technical bottleneck of liposomes, and provide technical guidance for targeted release and controlled release of liposomes.
