Answer:
Explain how natural resources are identified:
Satellites are machines that are launched into space. They move around the Earth to get information that can help identify natural resources. How do satellites do this? Satellites scan the Earth’s surface to get information about its color and brightness. This information is used by a computer to make a “computer map”. Once they finish the "computer map" a person would look at the map and determine which materials are which. These maps are not for showing a person how to get from one place to another, but for showing what the surface of Earth looks like and what it is made of.
Why are natural resources unevenly distributed:
The formation of these resources requires certain conditions. For example, copper ores are formed where there is volcanic activity. Iron ores were formed a long time ago when certain substances combined to form sedimentary and other types of rocks. So, iron ores could be found more often in places with environments that were just right for the formation of these rocks. Graphite forms when another type of rock, called metamorphic rock, is formed.

Answer:
The correct answer is - 1/41,493
Explanation:
Let assume the frequency of the two possible same allele genotype (dominant and recessive) in an inbred population is p and q. Then the frequency of heterozygotes (H) is denoted as:
2pq + 2pqF. ( where F is the inbreeding coefficient).
The frequency of the two different hoozygotes in inbred population can be calculated as:
p2 + pqF and q2 + pqF. (Where p and q are the allele frequency of the dominant and recessive phenotype.
Given: Frequency of Alkaptonuria (q 2) = 1:500, 000
=> q = 1/707
p = 706/707 ( Approx values)
solution:
Inbreeding coefficient (F) = 1/64
Therefore,
Frequency of Alkaptonuria in second cousins= q 2 + pqF
= 1/500, 000 + (706/707 x 1/707) x (1/64)
= 1/500, 000 + 1/45, 248
= 1/41,493 (approx)
Answer and Explanation:
Cyclins and cyclin-dependent protein kinases (CDPKs, cell proteins) also function to control the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins (mitotic cyclins) to be synthesized. M cyclins activate a second group of CDPKs which allow the cell to pass the G2/M control point and into mitosis.
In the G1/s check point, entrance into the S phase is blocked if the genome is damaged. In the G2/M check point, entrance into the M phase is halted if the DNA replication is incomplete. In the M phase, anaphase blocked if chromatids are not properly assembled.
If a cell lost the ability to be selectively permeable, then the cell wouldn't be able to get the nutrients or things it needs from outside the cell... There's a reason that the cell is selectively permeable (cell selects what it wants in or out of the cell).
