Answer:
hypha
mycelium
fruiting body
spores
Explanation:
<em>A typical fungi thallus includes many filamentous hypha that combine to form mycelium that grows underground, and produce a fruiting body reproductive structure that produce spores that disperse on the wind to new habitat.</em>
Fungi body are generally made up of hypha, a network of which forms the mycelium. The mycelium grows underground within the substrate and occasionally bring out fruiting bodies which bear the sporangium containing the spores. The spores act as agent of dispersal and are used to form new organisms when the conditions are right.
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.
Answer:
A (-7)/(1)
Explanation:
(-7)/(-1) would be a positive 7.
7/1 would be a positive 7.
(-7)/(0) would be 0.
Answer:
d. All of the above exemplify the difference between a population and an individual.
Explanation:
A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.
These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.
