Explanation:
Mitosis
Mitosis is one round replication and one round division, here genetic recombination is absent hence daughter cells are identical to parental cellIt includes two divisions: karyokinesis and cytokinesis Karyokinesis includes separation of sister chromatids from a replicated chromosome and includes four sequential sub-phases: prophase,metaphase,anaphase,telophase Prophase includes three major events: compaction of chromosome,assembly of mitotic spindle apparatus and disappearance of nuclear envelopeMetaphase occurs when all chromosomes are arranged at metaphase plateAnaphase includes two major events: separation of two sister chromatids and movement of sister chromatids towards their respective polesTelophase includes aggregation of two sets of chromosomes near the respective poles Telophase is followed by cytokinesis where cytoplasm is divided into two which results in the generation of two daughter cellsMeiosis I
Meiosis I is the long phase where number of chromosomes is reduced and just becomes halfSeparation of homologous chromosomes occurGenetic recombination also occurs in meiosis IAlso completed in four sequential phases: prophase I, metaphase I, anaphase I, telophase IMeiosis II
Meiosis II is similar to mitosis Also includes 4 phases: prophase II,metaphase II, anaphase II, telophase IISeparation of sister chromatids occur in Anaphase IIMeiosis II is similar to mitosis because it separates the chromosomes to have sister chromatids in each cell
In both these process, chromosome are separated and cell divides to make two cells out of one
The key difference is that in meiosis,two cells are divided to get four cells
Meiosis I helps to get genetically unique chromosomes,crossing over occurs and at the end of division one parent cell produces two daughter cells each carrying one set of sister chromatids whereas mitosis is used to make body cells occurring in body
Leslie argues that an organism called a Euglena is a plant because it is eukaryotic, has a nucleus, makes its own food, and is unicellular. Where is Leslie's error? Plants do not make their own food..
Answer:
Effective food supply was most likely an effect on society that resulted from improvements in blood handling during World War I and World War II.

Explanation: with a great tolerance to a wide range of conditions the species would adapt and thrive which would allow it to reproduce and have all it needs to survive, grow, and take over.
The T-chart by categorizing each statement as something that would most likely be relevant to gene flow or genetic drift. Some answers will fit in both columns depending on the situation. is random is a mechanism for evolution is often related to disasters is also called “migration” deals with movement between populations...

This is an organism or cell with two sets of chromosomes.
This is a haploid cell with half the reproductive information from the parent.
This is a cell or organism having half of the diploid chromosome number, symbolized by "n".
