Answer: Fossils of limb structures provide evidence that ancient and modern tetrapods are related because it backs up the fact that both ancient and modern tetrapods follow the one bone two bone many bone digit pattern. It suggests to how modern and ancient tetrapods have the ancestry which come from early tetrapods.
Hope this helps.... Stay safe and have a great weekend!!!!!! :D
Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.
A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results.

The answer to this question would be: <span>proceed through the trachea, bronchi, and then bronchioles.
After going pass the oropharynx the air will be going to trachea, </span>bronchi, bronchioles and will end in the alveolus. In alveolus, the oxygen from the air will diffuse to the blood while carbon dioxide will diffuse to the alveolus. The carbon dioxide is going out of the lungs when doing expiration.
