<u>Answer:</u>
Yes,We live in the Cenozoic era, and scientists know more about this era and epochs.
<u>Explanation:</u>
This is because the cenozoic period is one of the three main periods of earth's history which began about 66-million years ago, lasting to the present. It is the latest or the current era of life. In this era, the rock layers are preserved more and destroyed in much lesser degree as compared to previous eras.
The Cenozoic Age is often recognized as the Mammals age because many species of large animals have been annihilated, enabling the preservation and proliferation of smaller creatures as their hunters no longer existed.
Skin cells are made of proteins, water, and fat. But brain cells are only made up of amino acids, which ca make protein.<span />

DNA microarrays allow scientists to determine the genotype of a chunk of our genome and also measure the how the genes in that chunk are expressed. Using this technique has been essential in isolating genes that predispose people to cancers, and therefore allowing physicians to preemptively identify and monitor at-risk individuals. For instance, the genes BRCA1, BRCA2, and PALB2 have all been identified (using DNA microarrays) and linked to breast cancer. Knowing this allows individuals to seek out testing and take appropriate measures to prevent cancer/monitor the possible onset of cancer, which has proven to be life-saving.
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.
