Thats odd my answer didnt get published stranged, anhow what I was saying is that due to the surface area and mass of the tree is has enough bouyency to stay afloat because of the surface tension on the water with the tree.

Imagine a species with three loci thought to be on the same chromosome. The recombination rate between locus A and locus B is 35
Vesnalui [34]

Answer:

<h2>Recombination rate or recombination frequency between locus A and locus C is either 2% or 50%. </h2>

Explanation:

As given,

Recombination frequency between locus A and B is 35%, means that the distance between A and B is 35 cM.

Recombination frequency between locus B and C is 33% , means the distance between B and C is 33 cM.

Therefore, if the locus C is present between A and B, then the recombination frequency between A and C would be 2%

A-----C ----------B

A---C= 2%

A----B= 35%

B---C= 33%

So, here the recombination frequency between A and C is 2%, means their distance is 2 cM.

If the locus C is as,   A---35---B--33----C ;   A-----B------C

A-----B= 35%

B------C= 33%

A-----C= 33+35= 68%

As rule, maximum frequency can not exceed 50%, as here the Recombination frequency between A and C = 50%.

How are levees beneficial to human settlements? a. Levees prevent rivers from flooding their banks as often. b. Levees prevent r
balu736 [363]

The correct answer is (b) Levees prevent rivers from flooding their banks.

Levees are formed when water pushes the sediments to the side of a river. They serve as a natural barrier and prevents flood. This is very beneficial in terms of human settlement. Levees can be natural or artificial. They prevent water from going into the areas where there is a human settlement (bank of river). They prevent the rivers from flooding cities in a storm surge. If levees are broken the result can be disastrous for the surrounding area.

A snowshoe hare produces a white coat during the winter, allowing it to better hide from predators. As a result, it has thrived
lana66690 [7]

Answer:

A snowshoe hare produces a white coat during the winter, allowing it to better hide from predators. As a result, it has thrived and over time a majority of snowshoe hares in the population also produce white coats in the winter. Which of the statements is/are true?

The white-coated hare has a competitive advantage in its environment.

The new population of hares resulted from natural selection.

Explanation:

The analogy shown above describes the law of natural selection which explains why the organism that fits into a new environment survives as a result of inheritance of a distinct trait that differentiate them from others. Also, the organism has greater advantage over the environment because it has device means of survival over time
