Four different populations of an owl species were studied. Data were collected on population sizes and the frequencies of allele

s for one gene. The gene is not known to be under any selective pressures. If genetic drift is the only mechanism operating to change these allele frequencies over time, which population can be expected to show the greatest change and which can be expected to show the least change over time?
1- size 58, A=.75, a=.25
2- size 289, A=.95, a=.05
3- size 592, A=.80, a=.20
4- size 160, A=.88, a=.12
A) Greatest change = 3; least change = 4
B) Greatest change = 4; least change = 2
C) Greatest change = 2; least change = 1
D) Greatest change = 1; least change = 3

Tcecarenko [31]

<u>Answer</u>: A) Africa and South America only

As shown in the map, the fossil evidence suggests that Cynognathus lived on the modern day continents of South America and Africa. Thus, from this distribution and the fragmentation of the ancient landmass into today's continents, result in the distribution of Cynognathus offspring species also only within the continents of Africa and South America.

Decide whether the discovery should be considered reasonable or surprising:
Readme [11.4K]

Answer:

A. Surprising.

Explanation:

The above scenario is completely surprising because there are 10 planets in solar system and considering all the orbit approximately in the same plane. But amazingly half (five) of the planets orbit counterclockwise, while remaining five planets orbit clockwise (opposite direction).

Reasonably, all planet should be orbit in same direction but it's surprising that in a same solar system half are orbit clockwise and half are anticlockwise.

1. What three organelles are likely involved in Tay-Sachs?
olchik [2.2K]

Answer:Tay-Sachs is an autosomal recessive disease caused by mutations in both alleles of a gene (HEXA) on chromosome 15. HEXA codes for the alpha subunit of the enzyme β-hexosaminidase A. This enzyme is found in lysosomes, organelles that break down large molecules for recycling by the cell.

Which statement best describes a human influence on the biogeochemical cycles?
maksim [4K]

The statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.

<h3>What is eutrophication?</h3>

Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.

Eutrophication is one major effect of the anthropogenic activities that release inorganic nutrients such as phosphate, nitrate etc into aquatic ecosystems.

However, eutrophication has its negative impacts on biogeochemical cycle as it alters the cycling of these nutrients.

Therefore, the statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.
