Answer:

1. C.

2. D

3. D.

4. D.

Explanation:

1. Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.

2. Landslides are geologic phenomena that can happen suddenly or through imperceptively slow downslope movement. ... A "translational" landslide can happen rapidly and result in all of the soil on a hillside being stripped off and filling the area at the bottom of the slope.

3. Sedimentary rock contains fossils because it was built up layer upon layer, often trapping and preserving animals, plants, footprints, and more within the layers of sediment.

4. The Uplift of the Colorado Plateau. The Kaibab Limestone, the uppermost layer of rock at Grand Canyon, was formed at the bottom of the ocean. ... The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down.

Hope this helps! :D

In trout, Gene A affects body color and yellow color (allele a) is recessive to red. In a particular river system you find that

hjlf

Answer:

The frequency of the dominant A allele is 0,4 or 40%.

Explanation:

In this population, we have:

- "A" red body color Dominant

- "a" yellow doy color Recessive

So, individuals AA and Aa will be red and trouts aa will be yellow. In this case, 64% of the fish are red, so they are AA or Aa.

If the population is in Hardy-Weinberg equilibrium the following will be true:

$p^{2}+2pq+q^{2}=1$

Where:

$p^{2}=$ frequency of AA

$2pq=$ frequency of Aa

$q^{2}=$ frequency of aa

It is known that 64% of population is red, in other words:

$p^{2}+2pq=0,64$

Or AA+Aa=0,64

So, it is possible to find the value of $q^{2}$ (aa):

$p^{2}+2pq+q^{2}=1$

$(0,64)+q^{2}=1$

$q^{2}=1-0,64$ $q^{2}=0,36$

Now, there are two alleles in this population, therefore their frequencies will be:

$p+q=1$

So, from $q^{2}$ it is possible to find q and p:

$q=\sqrt{q^{2} }$

$q=\sqrt{0,36}$

$q=0,6$

And:

$p+q=1\\p=1-q\\p=1-0,6\\p=0,4$

Imagine that you are studying alien life-forms discovered on a distant planet. While geneticists are working out the genetic cod

34kurt

A phylogenetic tree based on morphology can be constructed using the presence or lack of characteristics. In this illustration, all aliens except the outgroup possess a spring tail, all aliens possess a fourth eye, two aliens possess two tails, and one alien has a grasping hand. The evolutionary relationships between these organisms can be hypothesized using these traits.

Aliens:

We can determine whether the following traits are present in the remaining aliens by using the group of aliens with the tail stalk as our test group.
Out group: a group that is maintained apart from the clade but is yet connected to it.
If we provide these aliens alphabets for ease of understanding, then aliens will be like in order.
We can use the group of aliens with the tail stalk as our test group to see if the following characteristics are present in the remaining aliens.
A group that is kept separate from the clade while yet being affiliated with it is known as an out group.
The aliens will appear to be in order if we give them alphabets for simplicity.

A hypothesis is a ___.

Aloiza [94]

Answer:

A hypothesis is a tentative/ preliminary statement of the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.

Explanation:

In science, the hypothesis is an idea or explanation that you then experience/test through study and experimentation. Outside science, theory or guess can also be called a hypothesis. The hypothesis is nothing more than an unbridled, wild guess but less than a well-established theory.

So, we can conclude that The hypothesis is a simple statement that defines what you think the outcome of your experiment will be.

Hope this helps.. 

Good Luck!
