Fertilizations occurs in the fallopian tube.

Point "a" is located where the fallopian tube is at

Hence, fertilization is most likely to occur at point A

Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.

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.

I will give brainliest and thanks to the first person to answer! :) What were the econauts in the biodome doing with their dead matter and how is it connected to the decomposers?

Answers

Answer:

Explanation:

the Econauts constructed an ecosystem sealed under glass—a biodome. Recently, the group noticed an ominous decrease in the populations of organisms: the ecosystem appeared to be in the process of collapsing. The occupants were safely removed from the biodome, but the cause of the crash is still a mystery.

The econauts buried dead matter below 6 feet and dead animals in bags =
decomposers need oxygen to exist so they couldn't get to the dead matter that deep in the ground or the dead matter in bags.
Decomposers died =
decrease in cellular respiration

decrease in cellular respiration =
less carbon dioxide in the air
The cycle goes on

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.

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.
