If two parents have dark hair, the child will most likely have dark hair.
If one has light and the other dark, the child has a 75% chance of having dark hair or a dark-dominated mix because the gene for dark hair is dominant.
If two parents have light hair, the child will most likely have light hair.
Of course, it gets a lot more complicated than this, the genes of the child's grandparents and great grandparents could be carried by the parents as well. So if the parents have dark hair but they each have a parent with light hair, the light hair gene will be carried by them and could be passed on to the child. That's how it is with genetic disorders, such as Systic Fibrosis or Sickle Cell Anemia.
Answer:
The processes that occur in the rocks and allow the formation of the fossils are the compaction and cementation of sediments.
Explanation:
Fossils are organic remains belonging to living organisms - animals or plants - that are deposited in the soil. In the course of time, rock sediments cover them until they are buried in the ground.
The process of fossil formation is due to the processes of compaction and cementation of the sediments.
- <u>Sedimentary compaction </u>consists of the lower layers of sediment being pressed by the upper layers that accumulate progressively, causing their thickness to decrease.
- <u>Cementation</u> occurs as a result of the loss of water through the sedimentary stratum, so the compacted fragments are joined, because the substances contained in the rocks contribute to the adhesion of the fragments to each other.
Fossils are usually found in sedimentary rock, which favors the process of conservation of these remains.

The tumor is growing and the tumor cells are distructive by damaging his brain and soon he will start to loose some function as memory or speech. The tumor must be under a radion treatment or removed imediatelly if that is possible.
Answer:
The correct answer is option D, that is, 2,4,6,1,5,3.
Explanation:
With the approaching of sound waves, ear pinna mediates it towards the external auditory canal, this makes sound waves to reach the tympanic membrane. This results in the vibration of the tympanic membrane, and as the malleus, that is, the first ear ossicle, which is attached to the tympanic membrane gets displaced.
This movement of the malleus further moves the stapes and the incus. As the footplate of the stapes is associated with the oval window, the movement of the oval window takes place. This movement of the oval window creates pressure waves in the vestibular duct's perilymph. The movement of these pressure waves takes place from the Oval window to the Round window.
At the time of this movement, the pressure wave distorts the basilar membrane on its path to the round window, resulting in the vibration of the basilar membrane and the hair cells situated in the membrane against the tectorial membrane.
The stimulation of the sensory neurons takes place in the vestibulocochlear nerve's cochlear branch due to the displacement of the stereocilia. Post this, information reaches the auditory cortex in the temporal lobe's superior temporal gyrus, and hearing takes place.
