Engineering Brightness Artifacts of Learning

Because of the Dominican Republic lack electricity, so we try to help them address light poverty problem, we came up with ways to provide electricity for them, and we had a vedio call with them to understand situations, during the call, the students asked questions about there to them, then we knew more question by this Vedic call. We found some energy-saving lamps to help them solve the problem of electric lighting.





My Environmental Interactions

Interactions Content: When the battery  runs out, I will wrap the battery and throw into the recyclable trash. When I run out of water, I turn off the water every time. Never bleach when washing clothes. Rarely use plastic bags, can not do not. Unused lights are turned off.

Choices: Turn off the water when it is used up. Eat how much to buy, do not waste food. The food packaging should be thrown into the trash can not readily dropped on the ground.

Changes: We should not overfishing, should be appropriate fishing. To reduce the number of chemical plants and pollution levels, and away from residential areas. The amount of fertilizer used should be appropriate, not too much can not be too little.

Post Format: We should protect our environment from pollution, save resources and not waste.

How do cells multiply

Reproduction Content: While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.

Meiosis Content: Meiosis is a division of the number of chromosomes in biological cells by half. Sex cell division, chromosome replication only once, the cells split two times in succession, which is the chromosome number halved a special division. Meiosis is not only a mechanism to ensure the stability of the number of chromosomes, but also a mechanism for species to adapt to the changing environment. The result of meiosis is that the number of chromosomes in mature germ cells is less than half that of primordial germ cells. Meiosis is a range of organisms that undergo sexual reproduction; the period is from primordial germ cells to mature germ cells.

Mitosis Contect: Mitosis refers to the process by which a eukaryotic cell divides to produce somatic cells. Mitosis, also known as indirect division, was first discovered in 1882 by W. Fleming and E. Strasburger in 1880. Characterized by the presence of spindle chromosomes, sub-chromosomes are evenly distributed to daughter cells, this division is generally found in higher animals and plants (animals and higher plants). Mitosis of animal cells and higher plant cells is different.

Content on how organisms grow:  Every living organism begins life as a single cell. Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow.
