The answer is D.
"An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure."
Answer:
The population would grow to 63,667 deer in a year, and the growth rate would decrease the following year.
Explanation:
Sika deer population : starting at 26000 in 2005
stabilized at 58000 between 2012 and 2014
rmax = 0.57
The population size of Sika deer be one year after the carrying capacity increased to 70000 as a result of deforestation
carrying capacity (k) = 70000
population size ( N ) = 58000
max growth(rmax) = 0.57
To determine the growth
dN/dt = rmax N [ (K-N) / K ] ---------- (1)
insert the given value into the formula above
dN / dt = 0.57 * 58000 [ 12000 / 70000 ]
= 33060 [12000 / 70000 ]
= 5667
The increase in population = 5667 + 58000 = 63667
Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the
phase,</em> - <em>the
phase,</em> - <em>the S phase; and</em>
- <em>the
phase</em>.
The phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of phase.
