That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Personality Test Based on Jung and Briggs-Myers This free personality test will allow you to obtain your four-letter type code according to Jung's typology as developed by Myers, Briggs, von Franz, and van der Hoop. Our test is one of several ways to quantify interpretations of Jung's typology, similar but not identical, to the MBTI test (the Myers-Briggs Type Indicator® MBTI), the Jung Type Indicator, and other such instruments. IDR Labs Personality Type Test is the property of IDR Labs International. Ours is one of the few free tests that is subjected to statistical controls and validation. Even so, please keep in mind that tests are merely indicators - a first peek at the system to get you started. Myers-Briggs Type Indicator and MBTI are trademarks or registered trademarks of the Myers & Briggs Foundation, in the United States and other countries.

It's Plantin' Time! One of the most anticipated science units in my classroom is our study of life cycles. We spend most of our fourth quarter studying the life cycles of plants, butterflies, frogs, and mealworms. It's one of my most favorite times of the year and one that my kiddos really look forward to! Our end of the year open house falls during this time and we made these flower booklets from myLife Cycle of Plants unit to showcase our plant study.
Eukaryote Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells each with half the number of chromosomes as the original parent cell (haploid cells). These act as sex cells (gametes – each gamete has just one complement of chromosomes, each a unique mix of the corresponding pair of parental chromosomes) resulting from genetic recombination during meiosis.
