Answer:

The correct answer would be - marbles represent alleles for a particular trait that has an allelic frequency of 0.5 in this simulation.

Explanation:

In this given representation or simulation to illustrate genetic drift, a student used marbles of different colors. She used 20 red and 20 yellow marbles in a population of 40 individuals. In this simulation, she used each marble color red and yellow to represent the allele for a particular trait.

That means red marbles represent alleles that are specific to a trait of a gene and similarly yellow marble represents another trait of the same gene. It is also represented that both alleles are present in the same number which means they have alllelic frequency of 0.5.

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2. So, if the mass of an object on Earth is 40 kilograms, its ma
Burka [1]

The weight of an object is the force of gravity exerted on that object and the mass of an object is the amount of matter it has, and it stays the same wherever you are, regardless of gravity. 

So, here the mass of object is 40 kg on earth, it means it has mass of 40 kg on moon also, but when we are calculating the weight of an object we used the following formula,

F=mg

Where F is the weight of an object in Newton and m is the mass of object in kilogram and g is the gravity

Now here gravity on the moon is 1.6 m/s2 and m is 40 kg

So, F = 40 x 1.6

<span>F = 64 N</span>

<span>mass of the object on moon is 40kg and weight of an object on moon is 64N.</span>

Explain how parasitism differs from commensalism.
babymother [125]
<span>Commensalism is an interaction in which one of those species would benefit, and the other one would not be affected. Parasitism is an interaction in which one of those species would benefit at the expense of the host organism. Thus, in commensalism we have one positive and one neutral result while in parasitism we have one positive and one negative result.</span>

An igneous rock interacts with wind and water over a long period of time. Which of these is most likely formed as a result of th
konstantin123 [22]

<u>Sediment</u> is formed as a result of interaction of igneous rock with wind and water over a long period of time.

<u>Explanation</u>:

An igneous rock is formed by the weathering of the molten earth material. If the igneous rock is continuously exposed to wind and water for long time then the fragments of the rock will get loosened. This causes the fragment to fall off and sediments will be formed.

Sediment is a material that is broken off from the rocks due to specific weather condition. As metamorphic rock requires high temperature or high pressure for its formation, it cannot occur with the interaction of wind and water.
