Describe the difference between fruit sugars and food sugars
timama [110]

Answer:

An advantage of using sports drinks for fluid replacement during exercise is that:
satela [25.4K]

An advantage of using sports drinks for fluid replacement during exercise is that:

c. they have a pleasant taste which encourages consumption.

Explanation:

  • If you are doing moderate exercise in a very hot environment, you may also lose electrolytes that can't be replaced by drinking water alone.
  • Sports drinks can help replenish electrolytes lost during exercise, and because they contain sugar, they can also give you a boost of energy to help you get through a workout
  • The best bet for rehydration is to consume a low-cal beverage that contains electrolytes such as sodium and potassium.
  • Good choices include sports drinks (go low-cal if your workout), try coconut water, or water with a slice of fruit. The refreshing hint of flavor may drive you to drink more
  • During exercise, the main way the body maintains optimal body temperature is by sweating. Heat is removed from the body when beads of sweat on the skin evaporate, resulting in a loss of body fluid.

All cells share the following common components except
Monica [59]

Answer:

All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.



Figure 1. This figure shows the generalized structure of a prokaryotic cell.

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.

Eukaryotic Cells

In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.

A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions.

Cell Size

At 0.1–5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 µm (Figure 2). The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell. Similarly, any wastes produced within a prokaryotic cell can quickly move out. However, larger eukaryotic cells have evolved different structural adaptations to enhance cellular transport. Indeed, the large size of these cells would not be possible without these adaptations. In general, cell size is limited because volume increases much more quickly than does cell surface area. As a cell becomes larger, it becomes more and more difficult for the cell to acquire sufficient materials to support the processes inside the cell, because the relative size of the surface area across which materials must be transported declines.



Figure 2. This figure shows the relative sizes of different kinds of cells and cellular components. An adult human is shown for comparison.

IN SUMMARY: COMPARING PROKARYOTIC AND EUKARYOTIC CELLS

Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. Eukaryotic cells tend to be 10 to 100 times the size of prokaryotic cells.

Healthcare workers analyze data in the form of tables and charts in order to
BARSIC [14]

Answer:

Healthcare workers analyze data in the form of tables and charts in order to analyze health care results.

Explanation:

To analyze any kind of data, it is important that the data is fully set in the form of tables, graphs, chart etc so that we can analyze it. Just noting random numbers or data and not organizing it will not help in analyzing the data and it would be a waste. A data that is organized is easier to read and understand. It tells about the progress of a patient. Even record keeping data in an organized manner helps the health care workers to easily reach them at the time of need or when a similar patient arises.
