o-na [289]

Answer:

Explanation:

Similar to a guard at the outside of a club, deciding who should be allowed in and who to keep out, the cell membrane is semi-permeable, regulating the movement of substances in and out of the cell with the help of protein channels.

The cell membrane is a double layer of lipids (fats) and proteins that surround a cell and separates the cytoplasm/ organelles from its surrounding environment.

Using data from the table above, select the best explanation for why that cell will be able to eliminate waste most efficiently?
fomenos
The correct option is this: CELL 2 WILL THE ONE THAT WILL BE ABLE TO ELIMINATE WASTES MOST EFFICIENTLY. This is because it has the highest surface area to volume ratio which facilitates the exchange of materials between a cell and its environment.
The rate of diffusion of materials into and out of the cell depends on the surface area to volume ratio of the cell. The higher this ratio, the higher the rate of diffusion.

Study these diagrams. The dots represent valence electrons orbiting the nucleus of an atom. Which diagram shows the valence elec
steposvetlana [31]
In the picture attached to this question, the two diagrams above did not show very well but I believe that the first diagram contain four dots, which means that the correct option is A.
Carbon has six electrons, that is why 6 is its atomic number is 6 . In writing electronic configuration, two electrons are usually placed in the most inner shell while the other shells will have 8 electrons each. In the case of carbon which has 6 electrons, only four will remain after 2 electron has been put in its inner shell. Therefore the number of electron in its outermost shell will be four.

Use the picture to tell if it is accurate , precise , or both?
Anton [14]

Answer:

Accurate - Yes

Precise - Yes

Explanation:

Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.

Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.

Note that, a measurement may be accurate but not precise or be precise but not accurate.

In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.

Therefore, the measurements are both precise and accurate.
