Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorp
ion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for 2 weeks as they grow big enough to take care of themselves. As baby scorpions grow larger, which process occurs in their body (somatic) cells?
a. Mitosis separates one cell into four cells.
b. Meiosis produces all of the new body cells.
c. Meiosis splits the chromosome numbers by four.
d. Mitosis makes copies of the cell nuclei.
The correct answer would be d. Mitosis makes copies of the cell nuclei.
Mitosis is a cell division in which one cell separates to form two daughter cells, each having an identical genome as of the parent cell.
Before mitosis, the cell replicates its DNA or genetic material, so that equal amount of genetic material can be distributed into the two daughter cells.
By the end of mitosis, two nuclei are formed in a cell which is followed by cytokinesis. Cytokinesis results in the formation of two daughter cells.
These cells then grow in size and divide again which helps in the growth and repair of tissues in multi-cellular organisms.
In specific, this type of asexual reproduction is called budding. In this type of reproduction, the offspring is completely identical to the parent and there is little room for variation as in the case of sexual reproduction. Other living organisms that exhibit this type of reproduction are yeast, bacteria, and protozoans.
The first thing to do is activate
EMS. Use cool or cold water to cool the burn for 10 minutes as soon as
possible. ( Do not use ice or frozen compress.) Early cooling will minimize the
depth of injury and decrease pain. Remove jewelry near the affected area. Cover
the injury with dry, clean pad loosely
to protect it. Do not give food or drink to injured person. Keep him comfortable
until EMS arrives and takes over.
Schleiden and Schwann proposed spontaneous generation as the method for cell origination, but spontaneous generation (also called abiogenesis) was later disproven. Rudolf Virchow famously stated “Omnis cellula e cellula”… “All cells only arise from pre-existing cells
