Answer
When testing the effect of temperature on pepsin enzyme activity, the results showed that pepsin worked best at the temperature 30 °C. When the temperature decreased to 22 °C, the enzyme activity decreased sharply. Turbot and redfish retained almost half of the activity at low temperatures (5 °C).
Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals.
Answer:
1. Evolution of chromosome number - fusion, deletion
2. gene trafficking - horizontal gene transfer, exon shuffling, birth of new genes
3. birth of new gene - exon shuffling, fusion and fission.
Explanation:
Evolution of chromosome number occurs due to the fusion and deletion of the chromosomes. Chromosome fusion may result in the speciation and isolation that rise the evolution in chromosome number.
Gene trafficking is the case that is arise due to various reasons such as forming new genes, horizontal gene transfer, and exon shuffling. However the birth of the new gene can be also arise by the fission and fusion and exon shuffling.
thus, the correct answer is - 1. Evolution of chromosome number - fusion, deletion
2. gene trafficking - horizontal gene transfer, exon shuffling, birth of new genes
3. birth of new gene - exon shuffling, fusion and fission.
Hey there!
The organisms on Earth do not run out of raw materials because: <span>all raw materials are recycled by various processes in an ecosystem. Which in this, this would be the reason on why we would not run out of our materials, that stuff we always recycle, in all types of ways in our ecosystem.
Hope this helps you bro! :)</span>
<span>Homeostasis Body's tendency to maintain a steady internal state; physiological equilibrium or balance around an optimal set point. [hot=sweat, cold=shivers]
Janice sweating on the treadmill in order for her body to cool off is an example of Homeostasis. Homeostasis is the body's ability to keep a steady internal temperature, state, equilibrium or balance around the ideal set point. This means when you are hot, you sweat to cool the body down and when you are cold your body shivers to help warm it up.</span>
