Choose one of the two major phases of photosynthesis. Draw a model of that phase that corrects one of the weaknesses in the student’s original model.

Answers

Answer:

Choosing light dependent phase of the photosynthesis process.

Explanation:

When the sunlight falls on the leaves of the plant, Light is absorbed by the leaves. The photosystem II captures or traps the photons of the light that leads to electrons of a chlorophyll in excited state with a very large energy charge.

Primary electron acceptor traps the excited electron and simultaneously electrons captured from the water as well. Electrons then move to the PSI (photosystem I) through cytochrome b6f. At the photosystem I these electrons result in the energy imbalance, the electrons that are captured by electron acceptor again that move it to ferredoxin that take them for the production of ATP to ATP synthase.

How do you think pollination takes place in flowering plants?

Answers

Answer:

My answer is down below.

Explanation:

Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species take place. After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begins to grow a tube. This tube is called the pollen tube.

Explanation:

insects typically pollinate flowers as they move from plant to plant searching for food. when an instects lands on a flower to feed, pollen grains sticks to its body. As the instects moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs.

Answers

Answer:

superposition

Explanation:    

Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle.

Sediments can be incrusted in horizontal layers in the ground, called stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.

Some geological principles allow us to date, relatively, the age of different geological events in the past.

Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.

Explanation:

Legumes are sufficient when it comes to nitrogen because they have nitrogen-fixing bacteria in their roots that convert nitrogen to nitrates for them. Thus, the correct option is C.

What are Legumes?

Legumes may be defined as a plant that has fruit or seed, is utilized for food, and belongs to the family of legumes such as pea and bean.

Legumes plants have an excess of nitrogen-fixing bacteria in their roots which assists them with a sufficient amount of nitrogen by converting the organic nitrogen into inorganic nitrates that are easily consumed by plants.
