What happens as a river gets older?

Biology
2 answers:
igomit [66]4 years ago

Answer: B. Its floodplain widens

As, the river gets older it accumulates larger number of water sources called as tributaries. Therefore, the volume of water will increase. Also, the soil near the water body is taken away by water flowing in a faster current due to soil erosion by water. This soil gets settled at the bottom increasing the channel of river flow. As, the river gets older the bottom bed becomes wider hence, will result in increased in water channel. Therefore, floodplains are wider in rivers getting older.

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 blood types are possible for a child whose parents both have AB blood type?
erma4kov [3.2K]

Answer:

-blood type a

-blood type b

-SOMETIMES type o but very rarely.

Explanation:

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
