When an oncogene is turned on and is not balanced through suppression
of tumor suppressor gene, the normal
cells become cancerous and divides unregulated.
Normal cells differentiate while cancer cells do not. Additionally,
while normal cells respond to endocrine
and paracrine signals from neighboring cells, cancer
cells do not. Cancer cells have malfunctioned
apoptosis process due to a malfunctioned p53
tumor suppressor gene. Therefore they
continue to divide even when they have damage to their DNA. Cancer cells metastasize because, unlike normal cells, they do not produce an adhesive molecule that allows the cells to adhere to one another to form tissue.
Hey there!
Answer: 400 k-cal
I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.
Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal
As we plug in this formula into our problem above, our answer would be explained below.
40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal
Answer: 400 k-cal
After the 1st half-life 250 g of the radioactive material will be left.
<span>After the 2nd half-life 125 g of the radioactive material will be left. </span>
<span>After the 3rd half-life 62.5 g of the radioactive material will be left. </span>
<span>Therefore after 60 minutes, 3 half lives would have occurred. </span>
<span>Therefore the half-life = 60 / 3 = 20 minutes when 250 grams of the original material would have remained radioactive. </span>
<span>Therefore the answer is A) About 250 gram of the material decayed in 20 minutes.</span>
