Answer:

According to the image, the approximate QT interval is 0.4 seconds.

Explanation:

The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.

Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.

In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:

0.04 seconds X 10 mm = 0.4 seconds.

Then, the estimated QT interval is 0.4 seconds.

first, drag the labels of group 1 to their respective targets to identify the types of sugars and the type of reaction shown.

Tasya [4]

drag the labels of group 1 to their respective targets to identify the types of sugars and the type of reaction shown .Disaccharide is created when a monosaccharide undergoes a dehydration event (loses water).

nomenclature and structures

The word "carbohydrate" refers to the majority of simple carbohydrates, which have the general elemental composition Cx(H2O)y. It is derived from the German "kohlenhydrate" and the related French "hydrate de carbone." According to the following imbalanced equation, their composition is related to the fact that they are created by photosynthesis from carbon dioxide and water:

Sugar + O2 + CO2 + H2O

The vast majority of naturally occurring carbohydrates present in living things, however, do not have the straightforward empirical formula Cx(H2O)y. Instead, the majority of naturally occurring carbohydrates are composed of oligomers (oligosaccharides or polymers (polysaccharides [Chapter 4]) by combining sugars with the other components of other molecules monosaccharide.

What modifies and transports proteins?

Alexandra [31]

Answer: The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER. It is also involved in the transport of lipids around the cell. Pieces of the Golgi membrane pinch off to form vesicles that transport molecules around the cell.
