The answer is the last one. Countercurrent multiplication in the kidneys is the way toward utilizing vitality to create an osmotic slope that empowers you to reabsorb water from the tubular liquid and deliver concentrated pee. It is discovered broadly in nature and particularly in mammalian organs.
Countercurrent multiplication was initially considered as a system whereby pee is gathered in the nephron. At first, concentrated in the 1950s by Gottschalk and Mylle following Werner Kuhn's hypotheses, this instrument picked up notoriety simply after a progression of confounded micropuncture tests.
Sorry if I’m late but I’m pretty sure it’s B! Yes
Answer:
The frequency of A1 be on Big Pine Key after a single generation of migration from No Name Keyp is 0.2276
Explanation:
Whenever it occurs migration between two populations, there is genetic flux going on. Genetic flux might be considered as an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flux acts homogenizing the allelic frequencies between the two populations, and it might introduce variability.
By knowing the allelic frequencies in both populations at a certain time and the migration rate, we can calculate the allelic frequencies of populations in the next generation. This is:
pA₂=pA₁(1-m)+pB₁ m
pB₂=pB₁(1-m)+pA₁ m
Being
- A one population and B the other population
- pA₁ and pB₁ the frequencies of the p allele before migration,
- pA₂and pB₂ the frequencies of the p allele after migration,
- m the migration rate
In the exposed example, we know that:
- No Name Key population allelic frequency: A1 = 0.43 and A2 = 0.57
- Big Pine Key population allelic frequency: A1 =0.21 and A2 = 0.79
Let´s say that p represents A1 allele, and q represents A2 allele.
The frequency of A1 allele (p) be on Big Pine Key (Population B) after a single generation of migration from No Name Key (Population A)
pB₂=pB₁(1-m)+pA₁ m
pB₂=0.21 x (1 - 0.08) + 0.43 x 0.08
pB₂= 0.2276
The allelic frequency in a population after one generation is the allelic frequency of individuals of that population that did not migrate (21 x (1 - 0.08) plus the allelic frequency of the new individuals that came from the other population (0.43 x 0.08).
You can corroborate your result by calculating the q allele frequency in the next generation and summing both of them up. The result should be one.
qB₂= qB₁(1-m)+qA₁ m
qB₂= 0.79 x (1 - 0.08) + 0.57 x 0.08
qB₂= 0.7724
p + q = 1
0.2276 + 0.7724 = 1
Yes, we can recover it. But not the same as before. Maybe we will make a new one. By planting trees and cleaning the area.The loss of biodiversity has two significant impacts on human health and the spread of disease. First, it increases the number of disease carrying animals in local populations. ... At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease carrying species.Participating in Biodiversity Conservation. Identify locations of critical wildlife habitat for species at risk and the threats to these areas. ... Keep vehicles on main roads to reduce the spread of weeds and disturbance to wildlife. Monitor and assess your pets' impact on biodiversity.
Hope this helped <3
