Hey there
the answer is
a Archean is a single celled microorganism and has no cell nucleus
and Bacteria <span>constitute a large </span>domain<span> of </span>prokaryotic microorganisms<span>. Typically a few </span>micrometres<span> in length, bacteria have a </span>number of shapes<span>, ranging from </span>spheres<span> to </span>rods<span> and </span><span>spirals</span>
so im going to say D as the answer
Hopes this helps u :)
Answer:
Two adaptations of Darwin's Finches that helped them to survive are:
- Behavioral adaptations to use tools for foraging.
Explanation:
There are fourteen species of Darwin's finches that originated from a single species of ground dwelling seed eating finch.
These Finches occupied different niche in the Galapagos island and were widely studied by Darwin.
These finches are one of the best Examples of Adaptive radiation.
Studies state that during severe drought in Galapagos island most vegetation dried out and a few softer seeds were left.
These few seeds were quickly fed upon by the birds and only dry , hard seeds were left.
Only birds who had large and hard beaks could feed on these hard dry seeds.
To Ensure survival the Finches developed adaptations which resulted in hard and large beaks so that they can feed on those dried hard seed.
Some groups started feeding on insects and got their beaks adapted to capture and kill insects.
Second line of adaptation included changes in behaviour and cognitive intelligence where birds started using tools for foraging.
Answer:
Bubbles are nothing but the oxygen which arise around the green parts of the plant.

The Earth was first considered habitable when we discovered that it was Microbial organisms that started the process. I would go with D.
