When Polypeptides join together, they form protein. The term Polypeptide chain is used to define the combination of Polypeptides. They are joined together by the peptide bonds. These Polypeptides are chains of amino acids. When one or more Polypeptide chains joined together, that is the time when Protein was born. As we all know, protein is very essential to our body. Because protein helps our body to function well. Protein makes our cells function properly. Can you imagine our body without protein? Thanks to Polypeptides chains that are joined together to form Protein so our body can function well. </span>
Number 4 is not part of the cell theory
The correct answer is B. Meet current and future resource needs.
Explanation:
Sustainability implies an equilibrium between the natural resources available and the resources humanity requires. This equilibrium is reached when the natural resources extracted from nature are enough to satisfy human needs without depleting the resources or causing these are not available in the future. In this context, the goal of sustainable development is to make sure now and in the future resource needs are meet (option B). Moreover, this is possible through actions such as recycling, reducing deforestation, creating environment-friendly technologies, among others that reduce the depletion of resources or preserve the environment.
Answer:
See the answer below
Explanation:
<em>The light microscope uses visible light to produce images of objects on its slide while the electron microscope uses beams of electrons to project the image of specimens. Color is a property of photons of light, hence, the light microscope is able to produce images of specimens in their natural colors </em>
<em>The areas of the specimen on an electron microscope in which the beams of electron pass through usually appear white while other areas appear black. Hence, the electron microscopes can only produce grayscale images of specimens unless a false color is added to make the images visually appealing.</em>
