Answer:
1938
Explanation:
Matthias Schleiden was a German botanist who studied the plant's cell and its structure under the microscope. In 1938 he contributed to the cell theory and stated that every tissue present in the plant is made of or cells and an embryonic plant is produced from one single cell.
In 1939 another scientist Theodor Schwann proposed the same conclusion after studying animal cells and concluded that the basic unit of life is cell and every organism on earth is made up of one or more cells. Therefore Theodor Schwann and Matthias Schleiden have great contribution in cell theory.
Answer:
I don't know where you got the four answers from, but I just spent 5 minutes trying to find the answer. The energy is suppose to go from the chloroplast to the mitochondria, to mix with carbon to become glucose. It is, however, called the Calvin Cycle. My apologies if I'm just misinterpreting the question, but this is the answer I found.
Explanation:
The right answer are all the three of them (1, 2 and 3).
Let's compare between a normal cell culture and a cancer cell culture:
- Normal or defined cultures: the cells only multiply during a limited number of degenerations (30 to 50 subcultures) then die: their life and their death is programmed. We then observe a decrease in their rate of proliferation, phase of senescence.
- Continuous culture or transformed or immortal lineages. The multiplication speed does not decrease (reproduction without limits, non-stop), which allows an indefinite number of subculture. The cells constituting these cultures lose the contact inhibition and grow in clusters or multilayer (multiple layers).
Answer:
taste and smell
Explanation:
triggers taste
example
hold your nose put a fruit candy in your mouth you will notice there will be a slight different taste
these molecules trigger basic taste
