In one to two sentences, explain how the shorelines can affect weather.

Answers

Answer:Coasts are sensitive to sea level rise, changes in the frequency and intensity of storms, increases in precipitation, and warmer ocean temperatures.

The ocean warms and cools more slowly than the atmosphere, thus coastal or shorelines weather tends to be more moderate than continental weather, with fewer hot and cold extremes.

What is shorelines?

The shoreline refers to the place where a large body of water, such as ocean, lake, or river, meets the land. Evaporation from the ocean, especially in the tropics, creates most rain clouds, influencing the location of wet and dry zones on land.

The shoreline or coastal zone often experiences a unique weather which results into a very special climate. Coastal meteorology is the study of meteorological phenomena within about 100 km inland or offshore of a shorelines or coastline.

Thus, from above, it is explained how the shorelines can affect weather.

Mitosis consists of specific phases that occur in a specific order. (PMAT!)

Prophase is the first phase of mitosis where chromosomes condense and become visible.  

Metaphase involves chromosomes moving to the center of the cell.  

Anaphase is where the chromosomes are equally pulled to either side of the cell.  

Telophase is where the chromosomes bunch up at either end of the cell and begin to unravel into their previous state.  

Cytokinesis then occurs where the whole cell divides between the newly forming nuclei.

describe how wind forms ocean waves in deep water and how these waves change as they develop in 6 sentences
PLEASE HELP

Answers

Wind-driven waves are created by friction between wind and surface water. When wind blows across the surface of an ocean the continual disturbance creates a wave crest. These waves can be created through local winds or distant winds. The waves can be affected by wind speed and wind duration. The faster the wind and the longer it blows, the bigger the waves. It also can depend on how far the wind blows uninterrupted.

I hope this helps :)
Wind forms ocean waves by creating friction between the wind and surface water. This creates a rising crest that forms into a wave. As the wind continues to blow, the waves also continue. Depending on the location, the waves change. For example, when deep water waves move to shallower waters, they change into breaking waves. As the wave travels into deeper waters, it slows down and the wavelength decreases.

Answer:

middle ear- hammer, anvil, stirrup

cochlea- cavern-like bone with tiny hairs and fluid

eardrum- membrane

outer ear- gathers sound

amplify- make greater

The correct match is gathers sound - outer ear, hammer, anvil, stirrup - middle ear, cavern-like bone with tiny hairs and fluid - cochlea, membrane - eardrum, and make greater - amplify.

The outer ear is the visible part of the ear and includes the pinna (the external ear flap) and the ear canal. Its primary function is to gather sound waves from the environment and direct them into the ear canal. The middle ear is a small, air-filled chamber located between the outer ear and the inner ear. It contains three tiny bones known as the ossicles: the malleus (hammer), the incus (anvil), and the stapes (stirrup). The cochlea is a spiral-shaped, snail-shell-like structure located in the inner ear. It is filled with fluid and contains thousands of tiny hair cells along its walls. The eardrum, also known as the tympanic membrane, is a thin, semitransparent membrane located at the end of the ear canal in the outer ear. Amplify means to increase the magnitude or strength of something. In the context of hearing, the middle ear's ossicles (hammer, anvil, and stirrup) play a crucial role in amplifying the sound vibrations that reach the eardrum.
