The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.

It is the Neptune. Uranus and Neptune exchanged spots amid a delicate ride out to their present circles. That is the finish of Steve Desch, an astrophysicist at Arizona State University, who conceives that the greater part of the gas monster planets came to fruition twice as near the sun as they are at show.

inessss [21]

Answer:

negative, inhibition

Explanation:

The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.

<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>

There are 3 different models of succession. These include;

  1. Facilitation model in which colonists modify the environment to favor the growth of later successional species.
  2. Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
  3. Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.

The chloroplasts of flowering land plants typically contain at least two photosynthetic pigments, chlorophyll a and chlorophyll
ruslelena [56]

Answer:

a) Photosystem I requires the use of light converting an excited NADP + electron, reducing it to NADPH. In photosystems I and II, the passage of electrons to a series of redox reactions will be shown due to the absorption of light energy by the chlorophyll molecules.

(b) The control must be RuBisco, because for most photosynthesis responses to light, temperature and carbon dioxide, it produces oxygenation and carboxylation reactions, thus reflecting kinetic properties.

(c) plants can increase the ability in a variable ecosystem thanks to the flexibility of photosynthetic pigments, through these the necessary solar energy for photosynthesis is captured, according to each light spectrum there will be a specific pigment.

Identify each adaptation as structural or behavioral adaptations.
Zina [86]

Answer:

Monkeys have a prehensile tail that allows them to grab and hold onto tree branches - structural

Moose make mating calls to locate potential mates - behavioral

Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters - structural

Humans have five toes on each foot to help them maintain balance - structural

Many birds migrate south for the winter in search of food - behavioral

Explanation:

The structural adaptations are adaptations that help the organisms to survive in their environment through development of physical traits that give them an advantage. Such adaptations are the thick layer of blubber of the whales, the five toes of the humans, prehensile tail of the monkeys, rotational toe of the clouded leopard, long of the giraffe etc. The behavioral adaptations are adaptations that help the organisms to survive in their environment, but they manifested through their actions, not their physical traits. Such adaptations are the mating calls of the moos, the migration of the birds in winter, the hibernation of the bears etc.
