Answer:

Prevent the passage of certain molecules into the cell.

Explanation:

Cell membrane or plasma membrane consists of lipid bilayer in which proteins are embedded. The carbohydrates are present in the plasma membrane in association with lipids and proteins.

The cell membrane acts as the semi-permeable membrane that allows the movement of selected particles into and out of the cell. The molecules may enter through diffusion, osmosis or by active transport depending on the tyep of molecule.

Thus, the correct answer is option (C).

In your own words, explain how hiv/aids damages the immune system
Anastasy [175]

Answer:HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

How one rock can be transferred into either of the other rock type
mart [117]

Rocks can be classified in to three main groups - igneous, sedimentary and metamorphic. These three different rock types can be found in distinct areas of the UK.

Igneous rocks - these rocks are a result of volcanic activity in the past, when Britain was close to a plate boundary. Some of the igneous rocks are due to lava erupting at constructive plate boundaries. When the lava reached the surface, it cooled and solidified to form basalt rock. An example of this is the Giant's Causeway in Northern Ireland.

Other rocks are formed by hot molten magma beneath the Earth's surface cooling and solidifying as an intrusive rock under the ground, such as granite. This is later exposed as the rocks above are weathered and eroded at the Earth’s surface.

Sedimentary rocks – these are made up of small particles of sand and rock, which have been transported by the wind, rivers and ice and are usually deposited on lake or seabed. Over many millions of years, successive layers of sediments accumulate. These layers of sediments are compressed by the weight of the deposits above, into sedimentary rocks. These rocks form in layers, known as bedding planes.

When sand is compressed it forms sandstone. When mud is compressed it becomes clay. Limestone and chalk come from the remains of dead plant, animal and marine species and are rich in calcium carbonate and contain fossils. Many of these rocks were formed over 300 million years ago, in warm tropical seas during the carboniferous period. The existence of these rocks is evidence that Britain was at a different latitude compared to today. This suggests movement of continental areas of the globe, which is explained by the modern theory of plate tectonics.

Metamorphic rocks - these are rocks that have been changed in shape and form by intense heat and pressure at a plate boundary or along a fault line. These rocks start as either igneous or sedimentary rocks and are crystallised under the intense heat and pressure conditions to form rocks such as slates, schists, and marble. These rocks are very hard in nature and are often used as roof material.

short answer

The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

What surface features does Comet Hale-Bopp have? Unless there is no surface features.
antiseptic1488 [7]

Answer:

  • The bright head of the comet Hale-Bopp, called the comma, is shown near the Sun. The combo is made up of dust and gas, concealing a solid comet nucleus made of rock, dust, and ice.
  • The solid nucleus or core of the hale bopp comet consists mainly of ice and dust coated with black matter, and ice formed mainly of frozen water but possibly other cold substances, such as ammonia, carbon dioxide, carbon monoxide and methane.

Hope it helps!
