How do both sodium and potassium ions travel​

Answers

Answer:

Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel

Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.

The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.

Explanation:

Answer:

The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.

Using the diagram above, answer the following questions: 6. True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false. 7. True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false. 8. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected? 9. Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected. 10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

Answers

FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energyarrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. The arrow C represents the emission of carbondioxide in the atmosphere. As you can see that the arrow is from the smoke that is emitted from the factories and industries and to the carbondioxide in the atmosphere.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.

When you did some experiments and picked out a bunch of random stumpy-tailed cats and mated them, they had some stumpy-tailed kittens and some regular-tailed kittens. You did the same with the the regular tailed cats, but they always had only regular tailed kittens. What does this tell you about the genotype of the regular tailed cats

Does DNA undergoes translation to produce proteins . RNA undergoes mutation to produce cell walls

Answers

Answer:

No

2. Yes

Explanation:

This is because DNA undergo transcription to produce RNA and RNA undergo translation to produce protein. Translation is the process where mRNA molecule is used as a template to produce protein.

RNA undergo mutation more than DNA and this is because the enzymes found in RNA viruses and participate in copying viral genomes is why it occur so. These enzymes does not have the abilities to recognize DNA damage that enzymes in most organisms have.

A new dog breed is less likely to cause an allergic reaction in humans. Which statement explains how artificial selection led to the development of this desirable trait?


Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.

Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.

Different dog breeds were chosen for nonallergic traits and bred with each other to obtain the new dog breed.

Dogs were trained over generations to not produce and release proteins that cause allergic reactions in humans to obtain the new dog breed.

Dogs were kept outdoors over generations to build up a natural defense against allergens in the environment to obtain the new dog breed.

Answers

Answer:

Each constellation is a region of the sky, bordered by arcs of right ascension and declination. ... Together they cover the entire celestial sphere, with their boundaries adopted officially by the International Astronomical Union in 1928 and published in 1930.

Explanation:

- Eijiro <3

Love the pfp by the way! :D

The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.

What is International Astronomical Union?

In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.

The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.

The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.

Thus, the correct option is A.
