c. C2H5OH
A common example of a nonelectrolyte is glucose, or C6H12O6. Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
Answer:
A. The lytic lifecycle allows viruses to reproduce more quickly but also kills the host and forces the virus to find a new host cell.
Explanation:
The lytic lifestyle of the viruses (e.g. bacteriophage) can be described through the next steps:
- attachment and injection into the host cell (e.g.bacterial cell)
- synthesis of the early virus proteins which break down host's DNA
- virus uses host's machinery (for the replication, transcription and translation) to produce the rest of its proteins and to form new virus particles.
- host cell burst and many new virus particles are released.
During the lysogenic cycle, virus does not kill the host. It integrated its DNA into host's genome and stays dormant until conditions are optimal for reproduction.
Answer:
sea sponge
Explanation:
everything else is symmetrical, sea sponges are known for being whacky shapes and sizes and are never symmetrical
Answer:
C
Explanation:
because they are pests and can presents risks to humans
Answer:
Fossils are the greatest and simplest evidence of the presence of the organisms that existed many years ago.
Deoxyribo Nucleic Acid (DNA) is called as “coil of life.” According to the Darwin’s theory about 8 percent of human genome is made up from viral DNA which a person has accumulated through infections and diseases.
The case studies helps in figuring out the total evolution of species and organisms.
<u>Explanation:
</u>
<em>Fossil Records
</em>
But now Fossils are the feces and the footprints of the organisms which confirm the presence of an organism which are now extinct or rare to find.
<em>DNA evidence
</em>
DNA of an organism has sequences which mutate over a period of time and results in changes in organism’s genetics which later on evolve into new specie. Hence, the DNAs help to find the ancestors of the organism and also figure out the organism specifically related to. The process of study of evolution is known as Phylogenetics.
<em>Case Studies
</em>
The finch of Galapagos of Darwin’s is one of such example of evolution. The Galapagos Island helped in finding out the evolution occurred when the finches were secluded due to the geographical barriers.
