<h3>Answer:Bronchi occur before the bronchioles and bronchioles give rise to alveoli. Bronchi are surrounded by cartilaginous layer. Bronchi are involved in the conduction of air to the bottom part of the respiratory passageway. Bronchioles conduct air, and they are also involved in the gas exchange as alveoli.</h3>

Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentca
postnew [5]

Answer:

can lead to natural selection

Explanation:

<h2></h2><h2>Unequal reproductive success<em> _can lead to natural selection_____.</em></h2>

This is because if there is unequal reproductive success then one of the organisms is <em>better suited for reproducing, surviving, and passing down their genes to their offspring</em> rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where <em>i</em><u><em>ndividuals better suited for their environment produce more and have better survivality. </em></u>

So overtime, the organism which is weaker  (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in  a way "<u>Nature selected"</u><u> </u>the better fit organism.

Why do you think people like Ben Saunders explore extreme environments? Do you think you’d like to explore an extreme environmen
adell [148]

One major reason for exploring extreme environments is to find new resources. An example of a resource is the search for a new antibiotic. Extreme environments have rare species endemic to the regions which can offer different insights from the normative environment we are used to.

No, I would not. This is because the risk of death is higher in an extreme environment. Example of these risks are deadly diseases or harsh climate. The body may be unable to adjust to the extreme environment hence may be unable to restore homoeostasis;  such as in restoring body heat in extremely cold environments hence leading to hypothermia.

What is the endosymbiotic hypothesis?
stepan [7]

Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.

Explanation:

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
