Answer:
Small nonpolar molecules, such as O2(oxygen) and CO2(carbon dioxide)
Explanation:
Oxygen and carbon dioxide are soluble in the lipid bilayer (mostly because oxygen and carbon dioxide are lipids) and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O(water), also can diffuse through membranes but will have a hard time doing so, but larger uncharged polar molecules, such as glucose(carbohydrates), cannot.
Hope this helps! Brainliest?? Anyways have a great day my loves <3
As photosynthetic organisms, plants take up atmospheric CO2, chemically reducing the carbon. This represents not only an acquisition of stored chemical energy for the plant, but also provides the carbon skeletons for the organic molecules that make up a plants' structure.
Answer:
The correct answer is recall and interviewer bias.
Explanation:
Case-control study is a form of a retrospective study. In this, information is gathered from the past. As the data is collected from the past, it is subjected to memory bias, that is, also called recall bias. In the given case, interviewer bias can also take place because of the differences in the collection of data, interpretation, and procedures by the interviewers. The diagnostic and length bias generally takes place in a cohort study.
wait i may be dum but it sounds like your stating something rather then asking.. could you maybe reword the question?
<u>Answer</u>: Advances in molecular technology
<u>Explanation</u>:
- Earlier the phylogenetic relationship among organisms was established based on the physical features and behaviour of the organisms.
- With the advancement in molecular technology newer tools were developed which allowed to derive the relatedness among the organisms based on their genomic sequences (i.e. molecular characters).
So, <em>the relatedness among organisms has been revised based on the advances in molecular technology.</em>
