Explanation:
the is water everywhere
Answer: landforms
Explanation:
noah created a model of a glacier to help explain how glaciers change the surface of Earth. He froze two large blocks of ice. One block was pure water. The pther was water mixed with sand and rocks. He took both blocks and rubbed them across a sheet of tinfoil. The block of pure water slid smoothly over the tinfoil. The block with sand and rocks ripped the tinfoil in many places. How does Noah's model explain how glaciers change Earths surface?
Answer: The model is depicting the glacier erosion.
Explanation:
The glaciers are responsible for causing erosion of the earth. They transport the materials away from the locations were they are earlier situated. They carve the materials present beneath the land. They erode the materials like soil, pebbles, boulders, against the pressure of the unstable mass of the ice moving down the slope. The broken ice mass carriers away the broken rocks, materials and soil debris far away from the places where they have been originally situated. This causes the glacial erosion. Also the broken and displaced rocks displace the soil and other materials come in contact with during erosion.
According to the given situation, the ice formed with water only had no impact on the tinfoil on the other hand the ice containing the sand and rocks removed the tinfoil from places. This is because of the friction created by the sand and rocks on the tinfoil. The glacier material like ice, soil, rocks due to friction erode the material come in contact with it with an appreciable pressure underneath.

Can be searched quickly for the most relevant observations. Therefore, option (C) is correct.
What is a database?A database is a collection of organized data that can be searched, updated, and analyzed to obtain specific information or insights. One of the main advantages of a database is that it allows for quick and efficient searching and retrieval of relevant information.
This is particularly useful for sharing information among multiple users, as it allows for easy access to the same data from different locations and at different times. While a database can be used to store a wide range of information, it is typically not used to evaluate the validity of a logical argument, measure natural objects, or identify sources of error in an experiment.

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary ls7c week 1
Answer:
Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.
Explanation:
Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.

Why does the bronchioles get smaller and smaller before they reach the alveoli?
Answer: Parasympathetic stimulation causes bronchoconstriction while sympathetic stimulation causes bronchodilation. During an asthma attack, the muscles that encircle the airway tighten or constrict, limiting the flow of air to and from the lungs.
Explanation: i hope this answers your question and i have a awesome marvelous day.
Answer:
In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways -the smallest, called bronchioles lead to tiny air sacs (alveoli)
the bronchiole end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood, after absorbing oxygen, the blood leaves the lungs and is carried to the heart, the blood then is pumped through your body to provide oxygen to the cells of your tissues and organs.

Before 1896, many scientists concluded that light could not pass through black paper. In 1896, Henri Becquerel observed that uranium salts could cause a plate covered by black paper to react as if light had reached it. How did this observation affect conclusions about light passing through black paper?
A- Scientists ignored Becquerel’s evidence because uranium is dangerous to use, so his study was not valid.
B- Scientists repeated Becquerel’s experiment until it no longer worked and reported that his conclusions were not valid.
C- Scientists had to revise their earlier conclusion because evidence from Becquerel did not support the original conclusion.
D- Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion.
Answer:
D
Explanation:
So, I mean it’s kinda hard to explain given that it just makes sense and I took the test and I was right soooooooo
Yeah
Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion. Therefore, option (D) is correct.
What happens to light on the black paper?A sheet of black construction paper would obstruct light when you tried to shine a flashlight through it. The other side would not be able to see the light, and it would not be reflected. A black item absorbs all light waves and transforms them into heat, which causes the object to warm up.
Uranium, according to Henri Becquerel's theory, would absorb light and reemit it as x-rays. The uranium was placed on photo plates by him. When the plates were developed, he saw that the uranium had in fact been generating radiation resembling x-rays.

If a plant were unable to produce root caps, what would be the effect on plant function?
O The plant would have enlarged root cells.
The plant would have damaged root cells.
O The plant would not be able to grow to normal height.
O The plant would not be able to absorb water from the soil.
Answer:
The plant would not be able to grow to normal height.
Explanation:
If a plant does not develop a root cap, the plant does not allow the root to grow downwards.
Hope this helps :)
If a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.
What is the significance of the root cap in the plants?The root cap contains cells that are capable of secreting slime, which helps the root to move easily through the soil, helps to maintain the proper orientation of the root tip so it can efficiently absorb water and nutrients from the soil, and acts as a barrier that protects the delicate root tip cells as the root grows through the soil.
