First law is Law of Conservation of Energy it states that enegy cant be made in a isolated system. The second law is Law of Thermodynamics it states that the entropy of any isolated system always increases.
Natural selection is a process where living things that are better adapted to the environment around them survive longer and produce more off springs .
Answer:Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. So enzymes speed up reactions by lowering activation energy
Answer:
If there is homologous chromosomes (metaphase I) or duplicated chromosomes/sister chromatids (metaphase II) in the middle of the cell.
Explanation:
Meiosis involves two series of nuclear divisions grouped into meiosis I and meiosis II. Each division has the same number of stages i.e prophase, metaphase, anaphase, telophase etc. Meiosis I involves the separation of homologous chromosomes i.e similar but non-identical chromosomes from each parent.
On the other hand, meiosis II involves the separation of sister chromatids (duplicated chromosome). Since METAPHASE is generally characterized by the alignment of chromosome at the middle of the cell for separation in the anaphase stage, it means that the difference between metaphase in meiosis I and II will be whether it is homologous chromosomes that are in the middle or sister chromatids.
Therefore, according to this question, I would know if the cartoon is in metaphase I or II if:
- there are homologous chromosomes in the middle of the cell (metaphase I)
- there are sister chromatids in the middle of the cell (metaphase II).
I think that the correct answer is reactants of photosynthesis.
