Mitosis
Involves one cell division?
Results in two daughter cells
Results in diploid? daughter cells? (chromosome? number remains the same as parent cell)
Daughter cells are genetically identical
Occurs in all organisms except viruses
Creates all body cells (somatic?) apart from the germ cells? (eggs and sperm)
Prophase is much shorter
No recombination/crossing over occurs in prophase.
In metaphase individual chromosomes (pairs of chromatids) line up along the equator.
During anaphase the sister chromatids are separated to opposite poles.
Meiosis
Involves two successive cell divisions
Results in four daughter cells
Results in haploid? daughter cells (chromosome number is halved from the parent cell)
Daughter cells are genetically different
Occurs only in animals, plants and fungi
Creates germ cells (eggs and sperm) only
Prophase I takes much longer
Involves recombination/crossing over of chromosomes in prophase I
In metaphase I pairs of chromosomes line up along the equator.
During anaphase I the sister chromatids move together to the same pole.
During anaphase II the sister chromatids are separated to opposite poles.
Similarities
Mitosis
Diploid parent cell
Consists of interphase, prophase, metaphase, anaphase and telophase
In metaphase individual chromosomes (pairs of chromatids) line up along the equator.
During anaphase the sister chromatids are separated to opposite poles.
Ends with cytokinesis.
Meiosis
Diploid parent cell
Consists of interphase, prophase, metaphase, anaphase and telophase (but twice!)
In metaphase II individual chromosomes (pairs of chromatids) line up along the equator.
During anaphase II the sister chromatids are separated to opposite poles.
Ends with cytokinesis.
A special group of chemical substances that are used to treat diseases caused by microbes are called antibiotics.
An antibiotic is a chemical compound that is toxic to other bacteria and is produced by a living thing, usually a bacterium. In a complex environment like soil, organisms undoubtedly use antibiotics to regulate the growth of competing microbes. Soil microorganisms frequently produce antibiotics.
Bacteria and fungi are microorganisms that produce antibiotics that help prevent or treat disease. With the invention of penicillin in 1941, antibiotics gained widespread recognition. Since then, they have fundamentally changed how bacterial infections in humans and other animals are treated.

The correct answer is: marsupials.
Marsupials are actually defined by their ability to hold the young in the pouches, where they can be well protected. Some examples are Kangaroos and Koalas.
Other answers are wrong: for example, gymnosperms are plants, not animals.
Answer:
the candle will go out
Explanation:
since without oxygen it can't burn in a closed environment the oxygen will either be to low or not even present
Answer:
The correct answer is option D. Disorder.
Explanation:
Life has some set of characteristics to be classified as a living organism or beings. These characteristics are regulation, energy processing which means change energy from one form to another, organization of structure or complexity, evolutionary adaption to change over a period of time and other characters.
The disorder is not is the characteristic of all life. It may present in some but not all.
Thus, the correct answer is option - D. Disorder.
