Answer:

Biological cycles

Explanation:

Energy, growth, evolutionary, and ecological are the various biological cycles. Energy cycle is about the transformation of one form of energy into others during various life processes. Growth cycle deals with an increase in size by the addition of new cells and cell enlargement. The evolutionary cycle describes changes in species and organisms with time. Ecological cycles are concerned with the cycling of nutrients between biotic and abiotic components of the system.

Since all these cycles are related to living beings, they are biological cycles.

Contrast the genetic content and the origin of sister versus nonsister chromatids during their earliest appearance in prophase I

Bogdan [553]

Answer:

Sister chromatids are identical forms of chromatids of a chromosomes. They are mostly formed by semi-conservative replication of DNA molecule of a single chromosome.Thus they are like 'photocopies' of original parent chromosomes; joined together at the Centromere.

They are exactly similar in all ramification; with the same gene and allele compositions..

However; slight differences arise between the two identical sisters due to mutation from errors at replication;and also in the length of telomere repeats.

Non-sister chromatids are dissimilar forms of chromatids of a chromosomes formed when each half of a chromosome at fertilisation from separate haploid sex-cells, of each parent. fused.They contain different genetic composition;because they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.

However, they are genetically similar in composition; if they are contained in homologous chromosomes. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by chromosomal crossing-over between the non-sister chromatids on the chromosomes ; therefore identical genetic characteristics are shared .

Answer:

The Excretory System, The Reproductive System and The Endocrine System.

The Excretory System includes your bladder, uterus, and some of your organs. It is also called the "Urinary System". The Reproductive System includes your birth canal. This system helps to reproduce the body to have babies. The Endocrine System includes your hormones. It helps the body to depend on growth development or mood.

1. Identify the steps of cell division in a prokaryotic cell.

iris [78.8K]

Answer:

1. Step 1: DNA Replication. Just before the cell divides, its DNA is copied in a process called DNA replication. ...

Step 2: Chromosome Segregation. The two chromosomes segregate, or separate, and move to opposite ends (known as "poles") of the cell. ...

Step 3: Separation.

2. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.
