Answer:
C. If spiders evolved first, six legs is the derived trait.
Explanation:
A derived trait is a characteristic that is <u>present in a species but was absent in the common ancestor of this species.</u>
Spiders evolved from a crab-like ancestor and, although crabs are decapods, they possess eight walking legs and two claws. As insects evolved after spiders, the 'new' or derived trait that was absent in the ancestor would be having <u>six legs</u>.
Therefore, in this scenario, Mr. Morales states that <u>spiders evolved before insects</u>, which indicates that <u>the trait of six legs is a derived trait</u> from the last common ancestor, a characteristic that separates arachnids from insects.

Answer:
Gqalpha.
Explanation:
The signalling processing occurs in the brain with the helps of different receptors, proteins and hormones. These receptors determines the taste sensation, visual and hearing sensation as well.
In case of the increase in the level of the diacylglycerol, the Gqalpha trimeric G protein bounds to the GTP. This subunit helps in the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2) to diacyl glycerol (DAG) and inositol trisphosphate (IP3) by activating the enzyme known as phospholipase C.
Thus, the answer is Gqalpha.
Answer:
deoxyribose
Explanation:
A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.
