A spider plant sends out runners that have buds. When planted, the bud grows into a mature plant. The resulting plant has one parent and is <u>genetically identical</u> to the parent.
Answer: Option C
<u>Explanation:</u>
Reproduction is of two types one is sexual reproduction and asexual reproduction. The asexual reproduction mostly involves only one parent and therefore the off spring that is born is genetically identical with the parent.
whereas in sexual reproduction that involves 2 parents the off spring born contains a genetic makeup that is a combination of 2 parents and thereby not genetically identical.
The cilia propel debris-laden mucus away from lower respiratory system structures.

What is function of mucous membrane?</h3>
- Another general defense against possible infections is provided by the mucous membranes that line the digestive, urinary, and respiratory tracts, as well as the nose, mouth, and lungs.
- In order to cover and protect the more delicate cell layers underneath it and to trap waste and particle matter, including microorganisms, mucous membranes are made up of a layer of epithelial cells connected by tight junctions.
- Because they feature ciliated appendages, which resemble hairs, the epithelial cells lining the upper portions of the respiratory tract are known as ciliated epithelial cells.
- Mucus that contains debris is forced out and away from the lungs by the cilia's movement. The mucus is then coughed up, sneezed out, or swallowed and destroyed in the stomach. The mucociliary escalator is another name for this route of elimination.

Answer:
Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.
Explanation:
Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:
G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.
S is the period of DNA synthesis, where cells replicate their chromosomes.
G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.
M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.
Question 4 is to consume food.
Answer: because the structure of their cell wall is unable to retain the crystal violet stain
Explanation:
Due to differences in the thickness of a peptidoglycan layer in the cell membrane between Gram-positive and Gram-negative bacteria, Gram-positive bacteria (with a thicker peptidoglycan layer) retain crystal violet stain during the decolorization process, while Gram-negative bacteria lose the crystal violet stain
