The most significant relic of this species is an upper femur that reveals indications of bone development typical of a biped, indicating that Orrorin tugenensis individuals likely walked upright on two legs while simultaneously climbing trees.
A hypothetical early Hominin species called Orrorin tugenensis was identified in 2000 and is thought to have existed between 6.1 and 5.7 million years ago. How Orrorin is connected to contemporary humans is unknown. Although this remains the most popular theory of human evolution as of 2012, its discovery was used to refute the idea that australopithecines are human forebears. The name of the only classified species, O. tugenensis, comes from the Tugen Hills in Kenya, where the first fossil was discovered in 2000. The name of the genus Orrorin (plural Orroriek) means "original man" in Tugen. Twenty fossils of the species have been discovered as of 2007.

Answer:
As far as I know, pollination is the most common way for flowering plants to reproduce.
Answer: Mutations in genetic code occurs when DNA is being duplicated.Any changes in the base pairs leads to mutations by trasition or transversion. Change in amino acid leads to change in sequence and thus, mutation. This si carried on to new generation, if it takes place in germ cells.
Explanation:
Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products.

Answer:
*furiously writes F until there was a true statement*
8. F (isotonic is where water diffuses in and out of the cell in equal rates to which it could move back and forth)
D.F (hypertonic solution is where the water will diffuse out from the cell as hypertonic solution's concentration is higher than the concentration of solute within the cell)
c.F (" but the water should be diffuse into the cell)
d.F (osmosis only related to water)
e.T (carrier proteins has the ability—it changes its shape to allow the molecules to pass through to the other side of the plasma membrane)
f. F (cuz facilitated diffusion issa passive transport and a passive transport must be going down the gradient aka from high to lower concentration)
