Fat has more than twice as many calories per gram as carbohydrates and proteins. A gram of fat has about 9 calories, while a gram of carbohydrate or protein has about 4 calories. In other words, you could eat twice as much carbohydrates or proteins as fat for the same amount of calories.
Answer:
All of the above.
Explanation:
To avoid an incident of a high-risk earthquake, the buildings must be shock-proof. Several steps are available:
- Implement new technologies for reinforcing new construction
-
- Build roads, bridges, and buildings near hills and fault lines
-
- Erect buildings close together using minimal construction materials
-
- Survey the ground to learn about its composition and stability
-
- Avoid entering or remodeling any structure older than 15 years
Answer:
Answer No 1:
The earliest evidence for the occurrence of viruses was the discovery of an infectious agent in the sap of a tobacco plant. Experiments were set with different filters from which bacteria could pass but viruses being even smaller than bacteria could not pass.
Viruses were difficult to study because they are very small and couldn't be seen even under a microscope.
Answer No 2:
Wendell Stanley made his studies on the tobacco mosaic virus (TMV). Wendell Stanley developed techniques and crystallized this virus. At that time, it was known that even a very simple cell does not undergo crytallization. Hence, Wendell Stanley got to known that this structure is some infectious agent which has the ability of crystallization.
Answer No 3:
The four forms of viral genomes are:
- double-stranded DNA
- single-stranded DNA
- double-stranded RNA
- single-stranded RNA.
Answer No 4:
The capsid can be described as proteins which make up a shell to enclose the genome of a virus. Capsomeres can be described as the protein sub-units from which a capsid is made. The shapes of a capsid can be characterized into
- rod-shaped: helical viruses, or inside spherical viruses
.
- icosohedral: icosohedral viruses or the heads of bacteriophages.
Answer No 5:
The components of a viral envelope involve phospholipids and membrane proteins and proteins and glycoproteins. The phospholipids and membrane proteins are derived from the host cell. The proteins and glycoproteins are of the viral origin.
Answer:
Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of <u><em> Bioremediation. </em></u>
To rid an area of mosquitoes, biologists introduced a species of fish into bodies of water that feed on the mosquito larvae. This method is an example of <em>Biological Augmentation.</em>
Explanation:
Bioremediation can be described as a process which uses plants or microorganisms to detoxify contaminants that are present in an area. The enzymes of a plant or animal tend to break down the contaminants and hence, we can make an area rid of contaminants in this way.
Biological augmentation can be described as a method by which organisms such as bacteria are introduced in an area to get rid of wastes.
The human body strives to maintain homeostasis, the state of balance between internal and external change.
