The theory of evolution can be proved by the comparison of DNA genetic sequences of organisms.
<u>Explanation:</u>
The evolution can be proved by following
- Homologous organs - they are organs that have similar basic structure but perform different functions. example: Human, Bird.
- Analogous organs-they are organs that perform same function but have different structure or basic design. example: Bird and insect.
- Fossils- the remains of dead animals and plants.
Dead organisms get decomposed by microbes, due to the absence of oxygen and moisture some body parts does not decompose.
The soft parts of body gets decomposed hard parts take time to decompose and get covered by sea, at these deep levels the decomposition stops and the hard parts remain preserved called fossils.
Answer:
Because their offspring cannot breed, they are considered separate species.
Members of the same species that produce offspring can continue passing on their genes through their offsprings offspring and so on and so forth

Explanation:
Bile acids are essential for the absorption of fat from the small intestines. ... production of the bile acids that allows for the vital digestion and absorption of the fats, oils and fat soluble vitamins
Plants used in first-generation crosses were called P, or parental generation, plants.Mendel collected the seeds produced by the P plants that resulted from each cross and grew them the following season. These offspring were called the F1, or the first filial (filial = daughter or son), generation.
Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
