The answer is Hominids became more dependent on vision over time and less so on their other senses. <span>This statement is related to the general decrease in the importance of smell and the increasingly significant use of vision. The stereoscopic (three-dimensional) vision and the appropriate perception of the resulting depth enabled the development of visual acuity over time.</span>
The answer is D.
Both mechanical and chemical digestion of food begin in the mouth.
Mechanical digestion involves physically breaking down food into smaller pieces. This happens in the mouth as the food is chewed. Adult humans have 32 specialized teeth which can tear, grind and chew different kinds of food.
Chemical digestion also begins in the mouth. It involves breaking down food into simpler nutrients that can be used by the cells. In the mouth, food is mixed with saliva. Saliva contains an enzyme called salivary amylase that begins the breakdown of carbohydrates. Salivary glands beneath and in back of the tongue secrete the saliva.
Answer:
5. all of the above traits combined
Explanation:
Phylogeny has to do with the study of evolutionary relationships among living organisms based on the premise of the theory of organic evolution that states that all living organisms came from a common ancestor.
Phylogeny incorporates molecular, morphological, anatomical, biochemical and behavioural traits in order to arrive at a phylogenetic tree that represents ancestral lineages.
<em>Hence, the correct option is option 5. </em>
Answer:
A. 100%.
Explanation:
Since both spiders have either AA or aa, every possible combination would result in an Aa genotype. And, because A is dominant to a, they will all display the A trait—be patterned instead of plain.
So it is 100%.
