Answer:
The xylem is located in the root, stem and the leaves of a plant.
The xylem contains dead cells arranged end-to-end forming continuous vessels. They have a hollow central space (lumen) through which water passes. They walls contain lignin.
The xylem carries water and minerals, up from the roots to the rest of the plant.
Answer:
The further away means it gets a weaker source if light and less reaches it.
Explanation:
Since the plant produces oxygen in photosynthesis, you can use this to measure the rate of photosynthesis. Which is affected by light and it's availability.
Answer:
How the sea serves us
> Many of the ecosystem services provided by the sea are threatened today by overexploitation, environmental pollution and greenhouse gases. Yet in many cases, how severely individual habitats are degraded and ecosystem services are impaired is just not known. Researchers are therefore attempting to assess the exact condition of marine ecosystems. Such analysis is important in order to plan concrete protection measures and to define critical limits and target values.

The bounty of the sea
> Since time immemorial we humans have been living with the seas and from their bounty. They provide us with food, mineral resources, transportation routes and other services. The climate-regulating effect of the oceans and the biochemical processes that take place in the sea are of fundamental importance. Today, some of these services are under threat, which i
The most unlikely characteristics of pioneer species is that they have long life cycles with slower growth and longer life spans.
<h3>What are pioneer species?</h3>
Pioneer species are the species to first colonize and adapt to a particular habitat.
Pioneer species are usually simple organisms with limited nutrient requirement and ate mainly photosynthetic.
They usually have short life spans.
Thus, the most unlikely characteristics of pioneer species is that they have long life cycles with slower growth and longer life spans.

This answer is about animals cell. first the deoxygenated blood goes to heart right side. then the heart pump the deoxygenated to lungs where the concentration of oxygen is higher so lungs make the D ox blood oxygenated and then sent again to heart left side which heart pump to deliever to all parts of body.
short cut= lungs and heart make the blood oxygenated.
hope it well help you
