How do polar water molecules pass through the plasma membrane? (3 points)
Water molecules pass through channel proteins to cross the membrane.
Water molecules can pass through the membrane freely and rapidly.
Water molecules dissolve into the lipid bilayer and cross the membrane.
Water molecules attach to cholesterol and cross the membrane.

Answers

Answer 1
Water passes through the membrane in a diffusion process called osmosis. During active transport, energy is expended to assist material movement across the membrane in a direction against their concentration gradient. Active transport may take place with the help of protein pumps or through the use of vesicles.

Which process would change metamorphic rock to igneous rock?

Answers

Answer:

If the freshly created metamorphic rock is exposed to enough heat, it may melt and become molten (magma). Igneous rock is formed when molten rock cools. Sedimentary and igneous rocks can both create metamorphic rocks.

The process that would change metamorphic rock to igneous rock is to treat metamorphic rock at extremely high temperatures and pressure that effectively transform it into a molten state. And this molten magma cools and crystallizes completely giving rise to the production of igneous rock.

What is Metamorphic rock?

Metamorphic rock may be defined as a type of rock that is significantly obtained due to the series of alterations in the pre-existing rocks. These alterations emerge due to changes in environmental conditions.

According to the context of this question, igneous forms are synthesized when the molten metamorphic rock cools and crystallizes due to the result of volcanic eruptions and melted rock inside the earth's crust. This happens due to the generation of extremely high temperatures and pressure.

Therefore, the process of formation of igneous rock from metamorphic rock is well described above.

what part of the cellular respiration pathway is affected by cyanide?

Answers

Eekekekeelewwwwxksms,skskskskksks,skskskskskekskdkdkkd

The ferric ions' cytochrome oxidase in the mitochondria makes a reversible chemical bond with cyanide. By preventing the conversion of oxygen to water, this essentially stops cellular respiration.

What is the role of cyanide in cellular respiration?

Heme-containing proteins include Fe3+, which cyanide binds to. As a result, the electron transport chain's terminal cytochrome complex IV is inhibited.

Cyanide's blockade of complex IV depletes ATP, which leads to cell death.

Because the molecules are so small and can disperse quickly throughout the entire body, cyanide can kill so quickly by damaging all major organs and tissues in a short period of time.

Therefore, electron transport system is affected by cyanide in cellular respiration.

how many calories are in an average trick-or-treaters halloween stash?

Answers

The number of calories on a Halloween stash depends on the type of candies and the number of units of each. If the stash contains 5 units of each of these candies: chocolate bars, taffies, lollypops, and candy corn the total number of calories is 1,650.

Calories are the most common unit used to define the energy a specific food gives to your body. For example, an apple has 52 calories, while a banana has 89 calories.

Considering this, in a Halloween stash the calories depend on two factors:

The types of candies or productsThe units of each one

Let's suppose there are 5 units of each of the following candies:

Chocolate barsTaffiesLollypopsCandy corn

Let's now calculate the calories

Chocolate bars = 220 calories x 5 units =  1,100 caloriesTaffies = 20 calories x 5 units = 100 caloriesLollypops = 83 calories x 5 units = 415 caloriesCandy corn = 7 calories x 5 = 35 calories

Add all the previous results:

what is a major difference between messenger rna molecules and transfer rna molecules?

Answers

Answer:

1) Messenger RNA molecules contain ribose, and transfer RNA molecules contain deoxyribose.

2) Messenger RNA molecules function in carrying coded information to the ribosomes, and transfer RNA molecules function in carrying amino acids to the ribosomes.

The major difference between messenger RNA molecules and transfer RNA molecules is that messenger RNA carries the genetic information, while tRNA carries the amino acids.

What is RNA?

RNA is ribonucleic acid. In the cell, different types of RNA are found, such as mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosome RNA), SnRNA, miRNA, etc. mRNA, or messenger RNA, is formed from DNA. It carries the information of a cell. The three consecutive nucleotides of mRNA make up a codon. An example of a codon is AUG.

tRNA has a cloverleaf-like structure. It has different domains such as the TΨC loop, the DHU loop, the anticodon region, and at the 3' end it is attached to an amino acid. The anticodon of the tRNA reads the codon sequence of the mRNA and attaches the amino acids. For the AUG codon methionine is attached.

Hence, the main difference between the messenger RNA and transfer RNA molecules is that mRNA carries the message of the genetic material, while tRNA carries amino acids to express the genetic material on mRNA.
