Answer:
6 koalas
Explanation:
<em>The maximum number of koalas that can survive in the area is 6.</em>
Each koala must eat 200 grams of leaves per day.
The trees in an area can provide a total of 1380 g of leaves per day.
The maximum number of koalas that can survive in this area would be the total amount of leaves production per day divided by the amount of leaves required by each koala per day.
Hence:
Number of koala the area can support = 1380/200 = 6.9
<em>Remember that each koala must eat 200 grams per day, therefore, the maximum number of koala that can survive in the area approximately 6.</em>
Answer:
Cells do not need to replicate their DNA, so there is no need to be in interphase
Explanation:
Interphase is the part of the cell cycle where the cell is not actively dividing. In this stage, the chromatin is decondensed. It is much longer than any stage in mitosos or meiosis, and is the normal state of the cells.
When a meiotic cell is in interphase before it is ready to make daughter cells, it replicates its DNA, ensures that the conditions are favourable for cells to divide (nutrients in good supply, all checkpoints for DNA damage are passed). Then it is able to divide.
Meiosis I generates 2 diploid daughter cells. At the end of this, the cell proceeds straight to meiosis II with no interphase stage, it moves straight to mitosis again.
This is because there is no need for DNA replication or further checks. The purpose of meiosis is to make 4 haploid daughter cells, so the cell will continue until this has happened. The diploid daughter cells made in meiosis I are simply divided again to make 4 haploid cells.
To be alive an organism must be able to intake nutrients, respirate, grow, and reproduce
Answer:
The frequency will be 35/36
Explanation:
An AAaa tetraploid plant will only produce a gamete which will be Aa, but during a self crossing a progeny with genotype AAaa will be produced and this will happen at a frequency of 35/36 and this simply means that the progenies produced during the self crossing will all have a dominant phenotype
