Answer:

The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

What is the chance of an accidental discovery happening?

Anit [1.1K]

A little bit less than a purposely discovery. A discovery that you've been looking for for a while would be like 75% of discovering but accidentally would be 35% of actually discovering something accidentally.

How do global systems interact to affect ecosystems?

miskamm [114]

is a functional unit that results from interactions of abiotic, biotic, and anthropogenic components and are a combination of interacting, interrelating parts that form a unitary whole. Ecosystems vary in size. They can be as small as a puddle, or as large as the earth itself. Basically, any living and non-living things interacting together can be considered an ecosystem. Within each ecosystem, there are habitats that vary in size. A habitat is a place where a population lives. A population is a group of living organisms of the same kind living in the same place at the same time. Natural ecosystems are made up of abiotic factors such as air, water, rocks, and energy and biotic factors such as plants, animals, and microorganisms.

Answer:

D Flow of protons across an electrochemical gradient

Explanation:

The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.

In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.

The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.

Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.

Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.

¿Cuáles son los alimentos que contribuyen una fuente rica en vitaminas y minerales ? A) Cereales y tubérculos B) Leguminosas y f

tino4ka555 [31]

Answer:

todas las opciones son correctas

Explanation:

Las vitaminas y minerales son micronutrientes esenciales que deben ser consumidos a través de la dieta parra llevar a cabo funciones metabólicas y fisiológicas diarias. Es importante destacar que existe una excepción a esta regla: la vitamina D puede ser sintetizada por células de la piel mediante una adecuada exposición a la luz del sol. Todos los alimentos destacados en las opciones mencionadas son ricos en determinados grupos de vitaminas y minerales:

- Cereales: ricos en vitaminas del grupo B y minerales, principalmente fosforo y potasio

- Tubérculos (por ej., la papa y la batata): ricos en vitaminas A y C, y minerales, principalmente potasio, fósforo y magnesio

- Leguminosas: ricos en vitaminas del grupo B y vitamina C, y minerales tales como potasio, hierro y magnesio

- Frutas y Verduras: ricos en vitaminas de todos los grupos y minerales esenciales tales como potasio, hierro, magnesio, fósforo, calcio, zinc, etc.

- Carnes: ricos en vitaminas del grupo B y minerales, principalmente hierro, fósforo, calcio, potasio, magnesio selenio y zinc
