ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H ) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis. Two types of processes that contribute to the formation of the proton gradient are: processes that release H from compounds that contain hydrogen, and processes that transport H across the thylakoid membrane.
Complete question:
ATP synthesis in chloroplasts is very similar to that in mitochondria: Electron transport is coupled to the formation of a proton (H+) gradient across a membrane. The energy in this proton gradient is then used to power ATP synthesis.
Two types of processes that contribute to the formation of the proton gradient are:
processes that release H+ from compounds that contain hydrogen, and
processes that transport H+ across the thylakoid membrane.
Drag the labels to the appropriate locations on the diagram of the thylakoid membrane. Use only the blue labels for the blue targets, and only the pink labels for the pink targets.
Note: One blue target and one pink target should be left empty.

Answer:
You will find the image and the answer in the attached files
Explanation:
Fosforilation of ADP to ATP occurs while electrons descend through the electron chain, from photosystem II to photosystem I.
Placed in the thylakoid membrane, there are molecules and complexes that participate in light-dependent reactions. The places that occupy these molecules in the membrane make possible ATP synthesis. Protons are released into the thylakoid space when the water molecules split in photosystem II. Membranes are impermeable to protons, so they can not leave the thylakoid space, nor enter without a protein transporter. Through the membrane, there is an electrochemical gradient as additional protons are pumped from the stroma to the thylakoid space, using the released energy as electrons move along the chain. ADP phosphorylates to ATP while protons move from the thylakoid space to the stroma in favor of the electrochemical gradient, through ATP synthase. ATP synthesis occurs in the stroma.
Is a river an abiotic or biotic factor
Is a river abiotic or biotic? A river is an abiotic factor.
Why? A biotic factor is anything living or used to be living while a biotic factor is something that is nonliving and was always non-living like a rock.

Describe how protists are helpful and harmful to humans and other organisms
( put this in a paragraph please)
Also describe how fungi are helpful and harmful to humans and other organisms. ( put this in a paragraph also please)
Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

B) There is 1 Kcal of energy available to the hawkC) There is 10 Kcal available to the shrewD) There is 100 Kcal available to the rabbitWhat is the flow of energy in a food web?The flow of energy in a food web is the transfer of energy from one organism to another as they consume and are consumed by other organisms.
The energy flow in a food web typically starts with primary producers, such as plants, algae, and some bacteria, which convert sunlight or chemical energy into organic matter through photosynthesis or chemosynthesis.
For every higher level, only 10% of the energy of the lower level is transferred.

What causes the difference in humidity between Florida and Las Vegas
Answer:
yep
Explanation:
Little or no humidity is not so true anymore, with the building up and more greenery. Las Vegas the humidly is not at all that low as it once once
The difference in humidity between Florida and Las Vegas is primarily due to their geographic locations and climate patterns.
What causes the difference in humidity between Florida and Las Vegas?Florida is located in the southeastern United States and is surrounded by water on three sides, with the Atlantic Ocean to the east, the Gulf of Mexico to the west, and the Straits of Florida to the south.
This proximity to water and the warm ocean currents that flow nearby create a humid subtropical climate, characterized by hot summers and mild winters with high levels of humidity throughout the year.
The low humidity in Las Vegas is due to the fact that the dry air has little moisture in it, leading to a lower amount of moisture in the atmosphere. Thus, there is a difference in humidity between Florida and Las Vegas.

3 and 16 for the second row
3 and 16 for the third row
1 and 16 for the last row
Explanation:
I did it on edge
The ratio of offspring with the described traits to the total number of offspring would be 9/16, 3/16, 3/16, and 1/16 respectively.
What are dihybrid crosses?They are crosses involving two traits. when the traits are independent, the phenotypic ratio of the resulting offspring follows the ratio established by Mendel.
In this case, the two traits follow the Mendelian pattern and thus, assort independently.
Hence, the traits and their respective ratios would be:
Brown body, Red eyes - 9/16
Brown body, brown eyes - 3/16
Black body, red eyes - 3/16
Brown body, brown eyes - 1/16

finds that each of the children has a different blood type. What are the genotypes of the parents? How
would you explain that all four blood types could be represented by these four children?
Answer:
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens.
