In four o'clock flowers, red petals show incomplete dominance over white petals. If two pink flowers are crossed, 50 percent of the flowers will be homozygous, and 25 percent of the flowers will be heterozygous.
Answer:
Exoskeletons provide less mechanical leverage.
Explanation:
There are two types of skeleton in living beings: the endoskeleton (which vertebrates possess, is lined with epithelial tissue and has bones and cartilage) and the exoskeleton, a skeletal structure that is located outside the body of the living being. , is an external skeleton. They are common in invertebrate animals, which have no internal bone structure.
The exoskeleton is a tough but flexible outer layer, not formed by bones, unlike the vertebrate endoskeleton. Its function is mechanical, chemical and biological protection, avoid excessive water loss, muscle support and serves as a connecting point for legs, wings and other appendages. However, this type of skeleton provides less mechanical leverage.
On the other hand, the endoskeleton is the name given to the internal skeleton, which is inside the body. This body structure is mainly seen in vertebrate animals and has the function of supporting and moving the body, as well as protecting some internal organs. Unlike exoskeleton, the endoskeleton provides more mechanical leverage.

Explanation:
Answer:
There are three main measures of central tendency: the mode, the median and the mean. Each of these measures describes a different indication of the typical or central value in the distribution.
Answer:
The intense and constant activity of insulin synthesis explains why pancreatic beta cells possess more rough endoplasmic reticulum and ribosomes than other cells.
Explanation:
Both ribosomes and the rough endoplasmic reticulum are necessary for protein synthesis to occur. In cells whose function is to produce substances, such as glands, the content of these cellular structures is higher in order to fulfill their function.
The pancreatic beta cells, located in the islets of Langerhans, have the function of synthesizing insulin, an endocrine hormone in charge of regulating the glucose content in the blood. <u>Because the beta cells constantly produce insulin, their content of rugged endoplasmic reticulum and ribosomes is high, in order to satisfy the demand for this hormone in the body</u>.
