According to the World Resource Institute, biodiversity is the variety of the world's organisms, including their genetic diversi

ty. In a world of genetically modified (GM) crops, agriculture is greatly reducing the genetic diversity of the plants on Earth. If we ignore genetic diversity while we develop GM products, we risk a disease or pest emerging that will wipe those types out. One answer to this problem is seed banks. Storage of material in the form of seeds is one of the most widespread and valuable ex-situ approaches to conservation. All BUT ONE is an advantage of seed banking over other ex-situ methods of biodiversity conservation. That is
A) seed banks take up little space.

B) seeds are viable for a very long time.

C) seed banks are expensive to maintain.

D) samples are very small and easily handled.

If a germ-line cell from a frog contains 10 picograms of DNA during G1 of interphase, then how many picograms of DNA would be pr
DIA [1.3K]

Answer:

10

Explanation:

The cell cycle is composed of three states: interphase, cell division and resting.

The interphase is composed of 3 phases: G1, S and G2 (in this order). During this state the cell prepares itself  for cell division. As part of the preparation the cell duplicates all its genetic material, that is, all its chromosomes. This duplication is done during the phase S.

During the meiotic cell division (composed of meiosis 1 and meiosis 2) a single diploid mother  cell (with duplicated chromosomes) produces four haploid daughter cells. the meiosis 1 produces two haploid cells with duplicated chromosomes, and the meiosis 2 produces 4 haploid cells with normal chromosomes (no duplicated).

If a germ-line cell from a frog contains 10 picograms of DNA during G1, then this cell will have 20 picograms of DNA before the product of the first meiotic division, and will have 10 picograms at the begining of the meiosis 2 (i.e prophase II)

How are mean and median alike?how are they different?
Vlada [557]

Answer:

Mean is the average you'll get when you add all your numbers then divide by the number of numbers you have. On the opposite side, median is the middle number within your list of numbers. If there isn't a middle number, take the two middle numbers and add them. Now, for how they are alike, I'm not so sure :'), but my closest guess would be they are fairly close together.

Sorry it's so long, hope I helped you :')
