What causes waves to occur in the ocean?

2 answers:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. These types of waves are found globally across the open ocean and along the coast.

<h2>Answer:</h2>

Waves in ocean are caused by winds

<h2>Explanation:</h2>

Waves are produced when there is a disturbance in a medium. Waves located on the ocean's surface are commonly caused by winds. Since waves are the carriers of energy so winds transferring its energy to the water, and big waves, or swells, can travel over long distances. A wave's size depends on wind speed, wind duration, and the area over which the wind is blowing along the air-water interface, creating a disturbance that steadily builds as wind continues to blow and the wave crest rises.

The primary neurotransmitter at the neuromuscular junction is

aleksandrvk [35]

Answer:

acetylcholine

Explanation:

In the pre-synaptic knob there are vesicles which contain a transmitter substance called acetylcholine. When an impulse reaches the synaptic knob, it stimulates the vesicles to move towards the pre-synaptic membrane releasing the acetylcholine.

The transmitter substance makes the membrane permeable. The neuromuscular junction contains the sensory neurone(afferent), motor neurones(efferent) and the relay neurones(connector).

Select the statements that accurately describe endocytosis. The cell membrane pinches off to form an extracellular vesicle joine

noname [10]

Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.

Explanation:

Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.

You examine an epithelial cell (skin cell) and notice the chromosomes are visible however it appears there are two nuclei in the

krek1111 [17]

Answer:

The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).

Explanation:

A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.

In mitotic telophase:

Chromatids, which are chromosomes, are found in the cell poles.
It initiates the formation of the nucleus membrane.
The chromosomes begin to turn into chromatin.
Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.

The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.

The other options are not correct because:

a and d. In the other phases described, S and G1, no chromosome distribution is observed at the poles.

c. A somatic cell does not experience meiosis.

I believe true because the Precambrian is the first geologic time, going back 4600-570 years ago, meaning it should contain the earliest of things.
