Mutualism when both parties benefit: Could be walking the dog to get exercise while giving the dog exercise. Or washing a pet so the pet is clean and they dont smell bad to you anymore <span />
Answer:
Tall offsprings: 13/25
Short offsprings: 12/25
Explanation:
According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:
13 tall pea offsprings
12 short pea offsprings
This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.
That is;
Tall offsprings: 13/25
Short offsprings: 12/25
In percentage, this can be represented as:
Tall offsprings: 13/25 × 100 = 52%
Short offsprings: 12/25 × 100 = 48%
Answer: D) Cartilaginous
Explanation:
The cartilaginous joints are the joints which allows the movement between the bones. They are of two types that are primary cartilaginous joints and secondary cartilaginous joints.
The primary cartilaginous joints are called as synchondrosis. These joints connect the bones with a hyaline cartilage. These can be found near the ossification centers.
The secondary cartilaginous joints are called as symphysis. These joints connect the bones with hyaline and fibrocartilaginous joints. These are usually found at the midline.
The pubic symphysis is an example of secondary cartilaginous joint. The joint is located between the left and right pubic bones, present in the midline of the body. It can be found above the external genitalia.
