Answer:
antibiotics are useless against viral infections this is because viruses are so simple that they use their host cells to perform their activities for them. so antiviral drugs work differently to antibiotics by interfering with the viral enzymes instead
Answer:
<em>Organisms that are eaten by the mayfly will increase.</em>
<em>Organisms that eat mayfly will decrease at first.</em>
<em>Organisms that eat mayfly would consume more of other organisms in their diet</em>
Explanation:
her get killed or they will migrate from the stream that is polluted. The population of the organisms on which the mayfly larva fed would increase as it will have a lesser number of predators now.
On the other hand, the organisms which fed on the mayfly would decrease at first as they will have a lesser amount of food available. They might find another source of food in order to survive.
You are studying two species of tree frog. The two species are found on two different islands, separated by 200 km of ocean water. Species A lives on very light-colored rocks and species B lives on dark-colored trees. Which process is most unlikely to be affecting allele frequencies in the population?
a. Gene flow between populations
b. Genetic drift
c. Natural selection
d. Mutation rates
Answer:
a. Gene flow between populations
Explanation:
Gene flow between two populations occurs when one or a few members of one population migrate into the other and interbreed in the new population. This process adds some new alleles to the new population. In the given example, two populations of a tree frog are separated by 200 km of ocean water. Therefore, the frogs of one population would not be able to migrate into the other population and interbreed. So, gene flow can not affect the allele frequencies of these two populations.
<span>This will create a
multi-nucleate cell. A multi-nucleate cell is a cell with 2 or more
nuclei but shares a cytoplasm. This
often occurs when a cell undergoes mitosis without cytokineses.</span> It seems
to be a common occurrence in animal cells.
The statements describe how traits are inherited are:
- Traits are inherited when genes are passed from parents to offspring.
- An offspring can receive different alleles or the same alleles from each parent.
<h3>What are traits?</h3>
Dominant traits are always expressed when the connected allele is dominant, even if only one copy exists.
Recessive traits are expressed only if both the connected alleles are recessive.
Polygenetic traits are basically the traits that are controlled by two or more genes.
Thus, option "3 and 5" is correct.
