Answer:

The answer is B. They have highly folded membranes.

Explanation:

A highly folded structure is advantageous for microscopic organelles such as the mitochondria and the endoplasmic reticulum. These organelles need to produce high amounts of ATP and proteins in a day, respectively.

For the endoplasmic reticulum, with ribosomes attached, it is responsible for the manufacturing, packaging, and transport of specific proteins. Same goes for the mitochondria, which is responsible for energy production and respiration. These processes are so demanding that in order to be more efficient in being productive, the highly folded membranes provide a wider and better surface area for synthesis of proteins or ATP, despite the size of these organelles.

Studentka2010 [4]

Answer:

BB - Dark brown color - (1/4)

Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)

bb - white color - (1/4)

Explanation:

Let the allele for dark brown pigment be represented by "B"

And the let allele for white (no pigment) be represented by "b"

Due to incomplete dominance, the phenotype of heterozygous species would be "light tan"

Genotype of heterozygous female - Bb

Genotype of heterozygous male - Bb

Bb * Bb

BB, Bb, Bb, bb

BB - Dark brown color - (1/4)

Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)

bb - white color - (1/4)

Synchondroses and symphyses are:
hoa [83]

Answer:

cartilaginous joints

Explanation:

The joint system is formed by the joints, which can be defined as the joining region between two or more bones. All bones in the body except the hyoid bone are articulated with at least one other bone. There are several types of joints, among them, the cartilage joints, those that have cartilage between the bones. If this cartilage is hyaline, the joint is called synchondroses; if the cartilage is fibrous, the joint is called symphyses.

The joints are responsible for holding the bones together and allowing the skeleton to move.
