The paper bags are less harmful than plastic bags because paper bags are made from the tree which is from nature.
<h3>What is plastic?</h3>
Plastic is a unnatural substance. It is bio degradable. The plastic is make stronger by the use of radiation.
The paper bags are made by hands. It contains no processing. While the plastic bags are modified in machines. They involves the use of harmful radiation.
Thus, the paper bags are less harmful than plastic bags.

Answer:
E) Either anaphase I or II
Explanation:
Failure of segregation of homologous chromosomes during anaphase I or failure of segregation of sister chromatids during anaphase II leads to the presence of the abnormal number of chromosomes in resultant gametes. In the given example, the egg mother cell with 48 chromosomes (24 pairs) would enter meiosis I but the failure of one pair of homologous chromosomes to segregate from each other followed by normal meiosis II would result in the formation of two gametes with one extra chromosome and two gametes with one less chromosome.
On the other hand, if the nondisjunction occurs at anaphase II of meiosis II, two normal gametes, one gamete with one extra chromosome and one gamete with one less chromosome will be formed. Therefore, nondisjunction at anaphase I or anaphase II would have resulted in the production of eggs with one extra chromosome.
B.
H in HF is slightly positive while O in H2O is slightly negative. So they attract in a polar bond. Btw I thought this is chemistry.
Analogous structures include wings in birds and insects homo-logous structures are DNA sequences due to a common origin, and a vestigial structure can be the human appendix.
<h3>What are analogous structures?</h3>
Analogous structures are traits that have the same function but they originated in different lineages.
Conversely, homo-logous structures have the same common origin but they may play different functions.
In conclusion, wings in different taxonomic groups may represent analogous structures, DNA sequences are homo-logous structures when they have the same ansestor and the human appendix is a vestigial structure.

Replacing native gel electrophoresis with SDS results in eluates with no enzymatic activity because it confers a negative charge to proteins, thereby neutralizing them.
<h3>What is sodium dodecyl sulfate?</h3>
The sodium dodecyl sulfate (SDS) is a detergent used in molecular biology laboratories.
This detergent (SDS) confers a negative charge to proteins, thereby neutralizing them (loss of their enzymatic activity).
In conclusion, SDS results in eluates with no enzymatic activity because this detergent may neutralize them.
