Answer:<u> Irrigation is the application of controlled amounts of water to plants at needed intervals. </u>

Explanation:

<em>Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall</em>

Answer:

Explanation:

Farming is a process that requires constant supply of water to aid crop production. During the ancient civilization in Mesopotamia, farmers grew crops in lands that had little rainfall and inadequate supply of water. What they did was to develop a means of controlling the flow of water from the river and channeling it to their farms. This was done by setting up canals and irrigation ditches to redirect the water to their farms. Regulators were developed to control the level of water in the ditches and canals, making it accessible to the farmers. At that time, each farmer was permitted to use a certain amount of water. The farmers take turn to water their field. When it was the turn of a farmer, the regulator is adjusted to allow the outflow of water from the canal into an irrigation ditch and finally, into the farmer's field.

High Energy electrons are transported from the chlorophyll to other molecules in the chloroplast by?

Reil [10]

Explanation:

High-energy electrons are transported from the chlorophyll to other molecules by electron carriers beginning with pheophytin, P0 (a form of chlorophyll), then A1 phylloquinone etc.

The chloroplast is an organelle attached to the membrane found in plants. This comprises many plasma membrane invaginations called the thylakoid membrane. It contains chlorophyll pigments, called granum in rows, while the organelle's internal areas are called the lumen. Water fills the granum and the stroma is created.

Further Explanation:

<em>During the light reaction: </em>

Photosystem II (PSII) contains pigments which consume light energy. This energy is exchanged between pigments until it enters the reaction core and is moved to P680; this transfers an electron to a higher level of energy where it then travels to a molecule of acceptors.
For those removed from photosystem II, water supplies the chlorophyll in plant cell with substitute electrons. Additionally, water (H2O) divided into H+ and OH-by light during photolysis acts as a source of oxygen along with functioning as a reducer.
The electron moves down the electron transport chain via several electron carriers
The e- is delivered (to PS I) where it has a continuous loss of energy. Such energy drives the drainage of H+ from the stroma to the thykaloid, which results in a gradient creation. The H+ pass down their curve, passing into the stroma by ATP synthase.
ATP synthase converts ADP and Pi to the ATP molecule, which stores energy.
The electron enters Photosystem I where it heads to P700 pigments. It's. This consumes light energy, transfers the electron to a higher energy level, and moves it on to an acceptor electron. This leaves room for another electron which is then replaced by a photosystem II electron.
In the ETC the NADP molecule is reduced to NADPH by supplying H+ ions. NADP and NADPH are vital to the Calvin cycle, in which monosaccharides or glucose-like sugars are produced after several molecules have been modified.

What happens when the number of organisms in an environment is higher

Marina86 [1]

Answer:

Explanation:

The population would decrease I believe because that means that if there is more organism that an environment can handle that means there won't be enough resources for all of the organism like food that means the population will slowly die off.

Suppose that a person takes a fall while hiking and develops tetanus when the pathogen enters through an open wound in their arm

qaws [65]

The tetanus infection is considered to be a Droplet infection.

<h3>What is Tetanus?</h3>

Tetanus is a neurological disease which is characterized by the occurrence of spasms in the muscle.

Tetanus can be caused if initial care does not take place after the wound occurs and therefore, it is very important to immediately take care of the wound.

To treat the wound tetanus immunoglobulin and tetanus toxoids are given to the person, however, it is necessary to give the two injections using different syringes and at different sites, because the immunoglobulin can cause neutralization fo the toxoid.

Thus, this could be the answer.
