I believe the plastics in the oceans are harmful to ocean organisms and human health when people consume ocean organisms. Each plant and animal play its own role in sustaining the world's largest ecosystem. However, due to the ever-growing waste of humanity, we are gradually upsetting this balance. As a global community, we are unable to effectively implement sustainable habits. We produce a lot garbage, and all that garbage has to end up somewhere.
Answer:
1 . The stage on the first meiotic division when the homologous chromosomes move to opposite poles but the sister chromatids remain together
: b. Anaphase I
2 . The stage in the second meiotic division where sister chromatids migrate to opposite poles
: c. Anaphase II
3 . A structure on the chromosome that holds a pair of chromatids together during replication
: f. centromere
4 . A double-stranded chromosome following replication attached by a centromere
: d. chromatid
5 . A condition where non-sister chromatid of homologous chromosomes exchange genes
: e. crossing over
6 . The stage in the first meiotic division where the homologous chromosomes line up as a pair
: a. Metaphase I
7 . The stage in the second meiotic division where the chromatid pair lines up at the equator of the cell: g. Metaphase II
Explanation:
DNA replication occurs during the S phase of the interphase of the cell cycle. The replicated DNA molecules are accommodated in two sister chromatids of a chromosome that are held together by a centromere.
During prophase I, the chromatids of a homologous chromosome pair exchange a genetic segment. This process is called crossing over. It generates recombinant chromatids with new combinations of genes.
Metaphase I of meiosis I includes the alignment of homologous pairs of chromosomes at the cell's equator. This is followed by separation and movement of homologous chromosomes to the opposite poles of the cell during anaphase I.
Metaphase II of meiosis II includes the alignment of individual chromosomes, each with two sister chromatids, on the cell's equator. During anaphase II, splitting centromere separates the sister chromatids which then move to the opposite poles of the cell.
RICE is the staple of South Korean diet while CORN is a staple of the US diet.
These preferences for food in these two countries are influenced by historical and social factors.
Most of the food in South Korea are usually prepared from rice while in the US most of the staple food are prepared from corn.
Answer:
<h2>A.controlled cell division </h2>
Explanation:
Thankyou
One of the main differences between butter and canola oil is that are room temperature one is a solid and the other is a liquid. This change in phase is due to the bonding between carbon bonds, the more double bonds that there are present the higher the melting point and the fluidity changes. Based on this the correct answer is C=C is found in canola oil while more C-C bonds are found in butter, making option 2 (C=C) the correct answer. In addition option 3 (C=H) can be ignored since hydrogen can only make single bonds. hope this helps:)
