ella [17]

Answer:

C. Phenotypes

Explanation:

Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.

Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.

So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.

Hence, the correct option is "C. phenotypes".

Why do you think some bones, such as the humerus and femur, have rounded ends? Why do you think other bones, such as the vertebr
alekssr [168]

Answer:

1. Their rounded shape allow them to joint properly with other bones, permitting a softer, better motion.

2. Provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.

Explanation:

The bone is a <u>connective tissue composed of specialized cells, a mineral-salt matrix, and collagen fibers</u>. The main functions of the bones are <em>organ protection, structure, red and white blood cell production and support.</em>

There are different types of bones:

  • Long
  • Short
  • Flat
  • Sesamoid
  • Irregular
  • Sutural

Some bones, such as the humerus and femur, are characterized by their rounded ends, also known as <em>epiphyses </em><em>(epiphysis - singular)</em>. The reason behind epiphyses is joint function. These bones are long bones, and their rounded shape allow them to ajoint properly with other bones, permitting a softer, better motion.

On the other hand, flat bones, such as vertebrae and carpals, provide protection for specific organs and their shape provides a broad surface for the proper attachment of muscles.
