Answer: O polar covalent bonds because oxygen is more electronegative than hydrogen
Explanation:
In the water molecule the two hydrogen atoms and one oxygen atoms forms the chemical structure in this the covalent bond is formed between hydrogen and oxygen and this is formed due to sharing of electrons between hydrogen and oxygen and oxygen being electronegative requires two electrons to complete its valency which are provided by two electrons each from one hydrogen and the O polar covalent bond is formed by this way.
Answer: The structure is chloroplast.
Explanation: Photoautotrophs are organisms that can synthesize food using light energy and carbon dioxide via photosynthesis.
Photoautotroph is a combination of two words: photo which means light and autotroph which means an organism that can manufacture its own food.
A photoautotroph manufactures its own food in a process known as photosynthesis. Photosynthesis is a process by which plants manufacture organic foods such as glucose using light energy, carbon dioxide and water. This process takes place in the chloroplast. A chloroplast is an organelle found in plant cells that contains chlorophyll which is the pigment that absorbs the light used in photosynthesis.
<u>ANSWER:</u>
"Publish experiment results only if they agree with current theories or public opinion" is an example of society which expects to follow ethical practices and meet many ethical standards. .
<u>EXPLANATION:</u>
- It is important for researchers to ensure that they conduct experiments on the basis of true and desirable data so that the results of the experiment can be accurate.
- Research ethics also require that experiments be undertaken only under favorable conditions and not under all circumstances.
- Sometimes, it is required not to conduct experiments and therefore researchers must refrain from the same.
- It is also essential as per research ethics for researchers to analyse data correctly and investigate all events and not only events that impact the lives and livelihood of people.
- Researchers need to conduct their experiments without any bias.
