Answer:
Explanation:
A diploid cell becomes haploid during Meiosis I and is completed after Telephase I. These homologous chromosomes (from mom & dad, all duplicated) pair up during prophase I forming tetrads. The pairs of homologs line up on the metaphase plate during metaphase I
At what stage of meiosis are cells haploid?
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid
Answer:
the ingestion of bacteria or other material by phagocytes and amoeboid protozoans
Explanation:
Phagocytosis, process by which certain living cells called phagocytes ingest or engulf other cells or particles. The phagocyte may be a free-living one-celled organism, such as an amoeba, or one of the body cells, such as a white blood cell
Answer:
Enzymes produce two new complimentary strands.
Explanation:
The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
