When you wake up a sleep walker, they will be startled, and can have an outburst.
Answer:
The correct answer is D. The outermost layer of a virion fullfills both protection and recognition functions of the virus.
Explanation:
A virion is a single viral particle. In this form the virus is physically isolable but without metabolic activity. Many virions can even be crystallized.
A virion, infecting a single host cell, is capable of producing thousands of descendants using the mechanisms of DNA replication, transcription and translation of the infected cell. This viral multiplication is often sufficient to kill the host cell by breaking it (lysandola).
Nucleic acid gives infectious power to the virion. It is enclosed by a protein wrap called capsid which is always formed by a number of individual proteins, called structural subunits. These subunits, associating in a specific way, form larger complexes called capsomeres. The set of nucleic acid and proteins is called the nucleocapsid of the virus, which can be enclosed by a membrane called pericapside envelope. Viruses without this membrane are called naked. Virus membranes are made up of a lipid bilayer, often associated with virus-specific proteins. The main function of the envelope is to help the virus enter the host cell. The surface glycoprotein serves to identify and bind to the receptor points in the host membrane. The viral envelope is then fused with the cell membrane, allowing the capsid and the viral genome to enter.
A step further down the evolutionary scale is the virino and below it the viroid and the prion; higher up is the virus.
DNA is a polymer that contains deoxyribose and a phosphate backbone. It contains these 4 nitrogenous bases: Adenine, Guanine, Cytosine and Thymine.
RNA on the other hand is a polymer that contains ribose and phosphate backbone. It contains 4 nitrogenous bases of: Adenine, Guanine, Cytosine and Uracil.
Hope that helps a bit.
A Personal Issue is an issue that is then of an individual or also in a relationship causing then a potential conflict or concern. If this will not be resolve or if nothing will be done then it can lead to a big problem then.
Answer:
See explanation below.
Explanation:
Catabolism and anabolism are <u>both biochemical reactions that are part of important process of metabolism.</u>
Anabolic and catabolic pathways 'need each other,' that is, <u>the energy that is produced from catabolism is utilized by anabolism.</u>
Anabolic reactions use <u>simple molecules to build complex molecules</u>, whereas the role of catabolism is <u>to break the large molecules and transform them into smaller ones.</u>
<u>Example of Anabolism</u>
<em>Photosynthesis:</em>
- The reaction between CO2 and H2O to form glucose and oxygen.
<u>Example of Catabolism</u>
<em>Digestion:</em>
- Breaking down of large molecules to produce energy.
