Answer:
When a substrate is added in water, the enzyme will cause the substrate to dissolve in water. Increase in temperature will cause better functioning of the enzyme and more solute to be dissolved until an optimum temperature. Optimum temperature can be described as the temperature at which the activity of the enzyme is highest.
After optimum temperature is reached, the enzyme will get denatured and the substrate will no longer be able to dissolve in water.
<span>Answer: “Comparing the mitochondrial DNA between different eukaryotes to see how closely they are related.”</span>
The endosymbiotic theory focuses on the origin of two eukaryotic organelles that have bacteria characteristics (mitochondria in animals and chloroplasts in plants). These two are s are believed to have developed from symbiotic bacteria.
<span>In designing an experiment that would support the endosymbiotic theory, the statement that would provide the best evidence is comparing mitochondrial DNA between different eukaryotes to see how closely they are related.</span>
Answer:
lysogenic
Explanation:
Phages can generate the lytic cycle or the lysogenic cycle, although very few are able to carry out both. If lysis is carried out, lysogeny cannot be carried out and vice versa. In the lytic cycle, phage host cells are lysed (destroyed) after replication and encapsulation of viral particles, so that new viruses are free to carry out a new infection.
On the contrary, in the lysogenic cycle there is no immediate lysis of the cell. The phage genome can be integrated into the chromosomal DNA of the host bacterium, replicating at the same time as the bacterium does, or it can remain stable in the form of a plasmid, independently replicating bacterial replication. In any case, the phage genome will be transmitted to the entire progeny of the originally infected bacteria. The phage is thus in a state of latency until the conditions of the environment are deteriorated: decrease of nutrients, increase of mutagenic agents, etc. At this time, endogenous phage or phage are activated and give rise to the lytic cycle that ends with cell lysis.
It is important in determining whether injuries/death was an accident or purposeful, and if purposeful, who, how and why did someone do it. They determine the weapon through the ligature marks left, the shape, force and impact of the injury, the location of the injury, and by analysing any fragments and trace evidence left on the wound
