Fossae are holes or depressions in the bones that are usually found on the end of the long bones. Fossae are good indications that a bone was connected or articulated with another bone. Therefore, if a scientist has found a fossa on a bone he or she could conclude that the bone was joined with another bone in the skeleton at the place of the found fossa.
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.

Explanation:
To decode which amino acids will be encoded by the sequence, first the strand must be translated. Remember G pairs with C and T (replaced with an U) with A.
With the translated strand once, use the amino acids decoder chart, and separate the strand in codons. For each codon follow the left column for the first letter, the top column for the second, and the right column for the third.
Answer: The steps are made of nitrogenous bases; deoxyribose sugars linked with phosphates.
Explanation: The rungs of the DNA are made of nitogenous bases (The nitrogenous bases are adenine (A), thymine (T), guanine (G) and cytosine (C) ) they are held together by weak hydrogen bonds.
The railings of the DNA are made of deoxyribose sugars which are alternating with phosphates. This part of the molecule is referred to as the "backbone".
Answer:
that carnivorous plants will invest more energy in nutrient uptake from the soil and less energy in prey capture whenever possible.
