In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
Technically enzymes but a enzyme is a protein so the answer should be protein
thriving sea
Explanation:
The fossils seen in the rich rock unit suggests that the paleo-environment of the area is a sea bursting with life.
- Fossils are the preserved remains of life found in rock units.
- Fossils can be used to interpret the nature of the past climatic condition in an area.
- Since different organisms have their habitat and the ecosystem which they thrive, their remains should define such an environment.
- Now, we have a collection of marine fossils here.
- The area must have been a marine environment based on this.

Answer:
D. Porine
Explanation:
Mitochondria are double membrane-bound cell organelles. The outer and inner mitochondrial membranes are quite distinct from each other with respect to their structures and functions. The outer mitochondrial membrane is permeable to small molecules and ions. Permeability of the outer mitochondria membrane is mainly due to the presence of integral membrane protein porins which make transmembrane channels to allow the free movement of these substances across the outer membrane.
On the other hand, the inner membrane is quite impermeable to most small molecules and ions including protons as it does not have porins. A substance can cross the inner membrane only through specific transporters. The inner membrane has the components electron transport chain and the ATP synthase.
Answer:
In 1831, Darwin embarked on a voyage aboard a ship of the British Royal Navy, the HMS Beagle, employed as a naturalist. ... Darwin's analysis of the plants and animals he gathered led him to question how species form and change over time. This work convinced him of the insight that he is most famous for—natural selection
