1.) Problem: Diff. Shape of the moon
<span>Hypothisis: earth, sun, n moon locations creates a shadow </span>
<span>Experiment: her experiment </span>
<span>Observation: Researching </span>
<span>Conclusion: she is yet to make one </span>
<span>2.) Size of balls - make them accurate </span>
<span>Research: use multiple sources </span>
<span>The amount of light: keep using the same light</span>
<span>Atherosclerosis is a common cause, because there is a lack of blood flow in the person's body, and this can cause a male to be impotent.
Diabetes is also a common cause because once again it causes less blood flow.
In a younger man, a cause could be anxiety. This is because nervousness and being anxious can lessen blood flow.
If you have choices, I suggest choosing one that has to do with less blood flow happening, which that is the main cause.
I hope that this could possibly help you with your studies, and have an amazing day. If you have any more questions, send me a pm. </span>
Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.
Explanation:
Epistasis is a type of gene interaction in which one gene masks or modifies the expression of another gene at a distinct locus.
Dominance refers to the gene interaction in which one allele of a given gene masks the expression of another alllele of same gene.
The comparison of dominance and epistasis give the following information:
- Dominance involves allelic suppression while epistasis involves non-allelic suppression.
- Dominance involves a single pair of alleles while epistasis involves two pairs of allele.
- In dominance, the expression of recessive allele is suppressed while in epistasis, either recessive or dominant non allele is suppressed.
- The effect of dominance is due to the dominant allele while epistasis may be due to dominant or recessive allele.
The Hardy-Weinberg equation is:
where p generally represents the frequency of the homozygous dominant population.
The q usually represents the frequency of the homozygous recessive population, and the 2pq term represents the frequency of the heterozygous population.
Answer:
ion
Explanation:
The atom then loses or gains a "negative" charge. These atoms are then called ions.
