Answer:
this is the answer straight off the site DO NOT COPY AND PASTE but along these lines is what its looking for
Explanation:
Radioactive decay is the process in which the nucleus of an unstable isotope spontaneously changes, releasing particles and energy. An unstable isotope will continue to decay until it reaches the stable form of either a different isotope of the same element that is stable or a different element that is stable.
good luck you can do this wonderful human!!!!!
5e6 cells in 10mL means we have 5 million cells in this volume.
We can figure out this by cross-multiplication:
5.000.000 cells ==> 10 mL
500.000 cells ==> x mL
so 500.000 x
=
1 mL.So you take
1 milliliter of your initial flask and transfer it to the new one.
The two methods used by breeders to increase the rate of mutation is radiation and chemicals.
The question is incomplete. The complete question is:
Plasmodesmata are cell junctions that are found between ________.
a) adjacent animal cells in the same tissue type
b) individual cardiac cells in heart muscle tissue
c) the plasma membrane of actively dividing prokaryotes
d) adjacent plant cells
Answer:
d) adjacent plant cells
Explanation:
Plasmodesmata are the cytoplasmic channels that connect the adjacent plant cells together and maintain the continuity of their cytoplasm. These are the narrow channels with 20-40 nm diameter. Plasmodesmata serve the function analogous to the gap junctions of the animal cells. The presence of plasmodesmata between the neighboring plant cells allows the movement of molecules and ions between them. Plant cells can adjust the diameter of the plasmodesmata according to the requirement to allow the transport of substances across them.
