The picture shows Poecilia reticulata, a type of guppy fish, found in a large variety of tropical environments. In some locations, populations of these fish have evolved over generations to become less vibrant in color and less spotted.

What is the most likely cause of this variation?
A
ecological succession, where individual guppy fish had less vibrant colors and formed a new population

B
artificial selection, where individual guppy fish were attracted to, and reproduced with less vibrant guppy fish

C
natural selection, where the less vibrant guppy fish avoided predators and passed on the genes to their offspring

D
reproductive isolation, where the population of less vibrant guppy fish only reproduced with individuals in one location

Answers

Answer 1

Answer:

Explanation: It seems more typical to change your color because of predators that can easily see you if you really vibrant

Answer 2

C, because camoflage helped the bland fish to survive and pass their genes.

3. How do gases from the air help break down rocks?

4. How does erosion make more soil? *

5. Explain how erosion can be helpful to the environment. *

6. Explain how erosion can be harmful to the environment. *

Answers

Answer:

4) Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.

5) Natural soil erosion can play a beneficial role in the environment too. ... The erosion also helped cleanse the soil of any useless materials, such as rotting tree matter or nutrient-less dirt from the area. The replaced soil can often become nutrient-rich and help plant life thrive.

6) The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Explanation:

3) Chemical weathering changes the molecular
structure of rocks and soil. For instance,
carbon dioxide from the air or soil sometimes
combines with water in a process called
carbonation. This produces a weak acid, called
carbonic acid, that can dissolve rock.

Explanation:

Henry visits his aunt's house on Jacksonville Beach several times a year. He notices how much sand is between the ocean and the seawall in June. During July, there is a hurricane. In September, Henry notices that there is much less sand between the ocean and the seawall. What is the best explanation as to what happened to the sand?

A.
The wind from the hurricane destroyed the sand.

B.
The heavy rains from the hurricane packed the sand down.

C.
The hurricane created giant waves that washed away the sand.

D.
The hurricane damaged the sea wall, and the sand behind it washed away.

Answers

I think C. Or D. But probably C.

The loss of sand causes the beach to become narrower and lower in elevation (Figure 1). Storm waves carry the sand offshore, depositing and storing the sediment in large sandbars. In weeks and months following the storm, the sand is returned to the beach by calm-weather waves.

The beaches are water body that is characterized by the presence of sand barriers. The sand was reduced as the giant waves created by the hurricane, washed it away. Thus, option C is correct.

What is a hurricane?

Hurricane is a natural disaster also called a tropical cyclone that is characterized by a storm system with a center having low pressure and the surrounding strong winds with a spiral rotatory movement. This leads to heavy rain and winds.

The hurricane in the oceans causes giant oceanic waves to form, that comes to the seawall and take sand away with them. This leads to a decrease in the sand from the beach area. The waves wash the sand from the land, as the seawater is pushed on the seashore by heavy rains and storms.

Therefore, option C. hurricane washes the sand off the coast.

Explain how sexual reproduction and the process of meiosis result in genetic variation.

Answers

Explanation:

sexual reproduction is the process of fusion of male gamete and female gamete producing a genetically different offspring .Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. meiosis leads to variation by forming new combination of alleles from maternal and parental chromosome

(choose which answers suits the question )

Explanation:

Meiosis leads to the formation of gametes which have half the number of chromosomes in the somatic body cells. This means two gametes should fuse together for a new individual to form. The two gametes coming from two different parents carry features from two individuals, and this is the first source of variation.

The process of independent assortment happens during metaphase I where the chromosomes from both parents align on the equator of the cell in an independent way, meaning some from each parent on one side, and the opposite on the other. This means the gamete formed has a mixture of chromosomes from the parent's parents, and this is the second source of variation.

Finally there is the crossing over which happens also in metaphase I where genetic material between the homologous chromosomes is exchanged. This means not the whole parental chromosome goes to one cell, but rather a mixture of both the paternal and the maternal in this one chromosome go to one cell, and an opposite mixture goes to the other. And this is the third source of variation.

Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.

Describe how the water molecules acted in the ice tray in the freezer

Answers

Answer:

Water is held together by hydrogen bonds, the strongest of inter-molecular forces. This is where a hydrogen atom in one molecule is strongly attracted to an electronegative atom (in this case, oxygen) in the other. When enough energy is absorbed by H2O, the molecules vibrate so vigorously that these bonds are loosened, giving them space to bounce around. This forms the liquid we all call and consider “water”.

Explanation:brainlest plz?

The molecules are moving because they have energy so as the liquid cools down, the amount of energy is reduced and the molecules start moving slower. When the temperature of water reaches about 0°C, the molecules stick together and form a solid – ice.

What is Solidification?

When the ice cube tray which contains water in liquid state is placed in the freezer, it gets converted into solid ice cubes due to decrease in temperature and this process of changing liquid to solid state is called solidification.

It is a phase transition where a liquid turns into a solid when its temperature drops below the freezing point. This established definition of freezing means the solidification of a liquid or liquid material of a substance by a phase change which occurs due to cooling.

Thus, the molecules are moving because they have energy so as the liquid cools down, the amount of energy is reduced and the molecules start moving slower. When the temperature of water reaches about 0°C, the molecules stick together and form a solid – ice.
