What is selective permeability?

Answers

Answer 1

Answer: Selective permeability, made possible in cells by the phospholipid bilayer that makes up the plasma membrane, is basically monitoring and regulating what can and can't enter the cell. It is carried out by a series of membrane proteins that act as channels to polar molecules, opening to allow them in and closing to prevent their entry. This is possible because the hydrophobic tails of the phospholipid molecules repel polar molecules and so prevent their entry unless through a channel.

Answers

The answer would be syllogism. This is a type of logical argument that applies deductive reasoning to get an outcome grounded on two or more suggestions that are declared or supposed to be true. Example: All mammals are warm-blooded. Therefore, all brown dogs are warm-blooded.

Part of a mountain that weathers fastest

Answers

The very top of a mountain weathers the fastest .

My reason being is mainly because it snows at the top because it's by the sky into the clouds and if it gets hot the top of the mountain will feel it first.

Example : in Spring the top of a mountain will basically bloom flowers , saying that the top will be effected first.

I really hope that this helps you out a lot.

Name four clastic sedimentary rocks and explain how these rocks form.

Answers

Shale, Siltstone, Sandstone, and Breccia are four clastic sedimentary rocks. Shale and Siltstone are formed in mud, Sandstones formed in sand. Breccia formed in gravel.

Final answer:

Sandstone, shale, conglomerate, and breccia are examples of clastic sedimentary rocks. They form when rock fragments, or clasts, are eroded, transported, and deposited in layers. Over time, they become compacted and cemented together to form sedimentary rocks.

Explanation:

Four examples of clastic sedimentary rocks include sandstone, shale, conglomerate, and breccia. These rocks form through a process called lithification. Initially, weathering breaks down pre-existing rocks into small fragments or particles. These particles, known as clasts, are then transported by natural forces like wind, water, or ice in a process known as erosion. Over time, these clasts build up in layers and eventually get compacted and cemented together to form sedimentary rocks.

Sandstone, for example, forms from sand-sized clasts, often in desert dunes or riverbeds. Shale is made of clay or mud-sized particles and often forms in calm water environments like lakes or deep sea beds. Conglomerates consist of large, rounded clasts and often form in fast-moving rivers. Breccia, on the other hand, is formed from large, angular clasts and usually forms near mountainous regions where there is a high rate of mechanical weathering.

The _____ biome is the driest. Common floras are cacti, and faunas are snakes and lizards.

Answers

The DESERT biome is the driest. Common floras are cacti, and faunas are snakes and lizards.

The desert biome has little to no rainfall. 20% of the Earth is covered by Deserts. There are four major types of desert in this biome.

1) hot and dry desert
2) semiarid desert
3) coastal desert
4) dry desert

Which factors provide the basis for the differences observed in the major land biomes on Earth?A.Average temperature and average precipitation
B. Average windspeed and average oxygen levels
C. Average day length and average night length
D. Average organic content and average mineral content in soil

Answers

Biomes are most influenced by their latitude, precipitation and their temperature.

A.Average temperature and average precipitation
-yes, this is a very good answer!

B. Average windspeed and average oxygen levels
-no, not as much

C. Average day length and average night length
-no, this has to do with latitute, but does not directly influence biome

D. Average organic content and average mineral content in soil
no, this is rather influenced by precipitation and by temperature, not the other way

Correct answer choice is:

A) Average temperature and average precipitation

Explanation:

Some people say there are only 5 important types of biomes aquatic, desert, forest, grassland, and tundra. Forests are divided into the rainforest, temperate forest, chaparral, and taiga plains are broken into savanna and warm grasslands, and the marine biome is divided into freshwater and marine.
