What are some geological characteristics of glaciers in Glacier National Park?

Answers

Answer:

The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.

what is the dominant impact that humans have on alpine glaciers?

Answers

The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.

What is Plant cell?

Plant cells are defined as eukaryotic cells that contain a true nucleus as well as specialized structures known as organelles that perform certain specialized functions. Plant and animal cells both contain a nucleus with similar organelles but plant cells differ due to the presence of a cell wall outside the cell membrane.

In the given figure, labelled organelles function are as follows:

Vacuole stores food, extra water, and waste while cell membrane permits selective passage of things into and out of the cell. The cell's nucleus serves as the activity's control centre, while the cytoplasm is the fluid that gives the cell its jelly-like consistency. Chloroplasts contain a substance called chlorophyll that is a green pigment that aids in photosynthesis. The cell wall of a plant gives it form, stiffness, strength, and protection.

Thus, the given figure represents a plant cell. So, the correct option is C.

What is cell cycle?

The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.

Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.

Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.

Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.

Answers

The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.

In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).

Characteristically, this channel has two transmembrane voltage-dependent gates.

When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.

Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.
