Answer:
Functions of the bones in the human body:
Support, protection, movement, mineral homeostasis
Explanation:
- Support: the bones provide a rigid support frame for muscles and soft tissues.
- Protection: the bones form several cavities that protect the internal organs from possible trauma. For example, the skull protects the brain against blows, and the rib cage, formed by ribs and sternum protects the lungs and heart.
- Movement: thanks to the muscles that are inserted into the bones through the tendons and their synchronized contraction, movement occurs.
- Mineral homeostasis: the bone tissue stores a series of minerals, especially calcium and phosphorus, necessary for muscle contraction and many other functions. When necessary, the bone releases these minerals in the blood that distributes them to other parts of the body.
Answer:
B
Explanation:
B is the most likely consequence because of the following facts we are told:
- After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees
- Adult apple maggots will only mate on the type of tree on which they were born.
This provides a geographical isolation (because they are feeding and laying eggs on separate trees) and reproductive isolation (because they will only mate on the type of tree on which they are born).
These two factors increase the chances that apple maggots feeding on apple trees will only encounter those who have mated on the same tree, and continue to mate this way. Over time, the populations (i.e. apple tree vs hawthorn tree) will intermix less and less. This will mean the genetic pool will become distinct, and natural selection will be acting differently (different habitats and different genes), encouraging speciation.
Jupiter is correct for this problem
The answer is; electron microscope
This microscope has the highest resolution than the other hence able to view smaller molecules. The reason for its high resolution is because it uses a beam of electrons to view its specimen. A beam of electrons has a shorter wavelength (in order of 1000s of magnitude) compared to visible light. Therefore, this microscope is able to view the structure of DNA and proteins.
