The appearance of fossils would the the answer.
Although there has been some scientific debate about what fossil strata should mark the beginning of this period, the "International Geological Congress" determined that the Cambrian period was approximately 543 million years ago of which the first appearance in the fossil record of worms that made horizontal burrows was discovered.
Answer:
converted into fat and stored in adipose tissue
Explanation:
When protein is taken in excess amount, because it cannot be stored in the body, it can be broken down to amino acids, which is further used as carbon skeletons to synthesize fats, which is then further stored in the adipose tissues.
When the body is not receiving enough calories from other nutrient sources like carbohydrates and fats, the available protein is the used as energy to meet the body's energy demands, by converting it to fat.
Note that, excess intake of protein can be harmful to the body.
Answer:
Famine.
Explanation:
Famine, a shortage of water or food, will often result in a significant population decrease.
Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.
<h3>
What are skeletal traits?</h3>
- The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
- Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
- Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
- We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).
