If they keep killing sharks, then the shark population will become extinct, I'm not sure if anyone wants to put a stop to it at all. About 100 million sharks are killed by humans every year.
Hope this is going to help you.
The correct answer is C. It is taken in from the air
Explanation:
Carbon dioxide is a gas that exists mainly in the air or atmosphere. Additionally, this chemical compound is required for plants as part of photosynthesis (process to produce energy). In this process, plants take dioxide from the air through the leaves' stomata, which are small spores, use this along with sunlight and water to produce energy, and later release oxygen. According to this, carbon dioxide is taken from the air by plants (option C) while oxygen is given off.
Answer:
Height
Explanation:
Height is polygenic trait which means that is controlled by more than one gene. This is different than Mendelian genetics in which one gene controls one trait-monogenic trait (e.g. flower color). Expressed phenotype of polygenic trairs is mix of all genes that control it (each gene has the same influence on phenotype) and it can express range of possible phenotypes (not only tall ad short but alos something in between).
This type of inheritance is known as polygenic inheritance or quantitative inheritance.
Traits that are also polygenic are skin and hair color, intelligence etc.
