One reason native plants are declining is that the invasive plants absorb nitrogen from the soil about twice as fast (α = 2). Ho

w low must you reduce this competition coefficient to enable the native species to persist? Assume that the native species has no competitive effect of the invasive species (β= 0).

Answer:

α = 0 if β= 0

Explanation:

If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.

docker41 [41]

Answer:

1. sphincter muscle and dilator muscle

2. Axial skeleton

Explanation:

1.The iris in the human eye is responsible for controlling the exposure of of light that reaches the retina. The movement of iris is controlled by a muscles called sphincter muscle and dilator muscle. sphincter muscle constricts the pupil in bright light while dilator muscle expands the pupil.

2.  Sternum belongs to the axial skeleton, which is a long flat bone located in the central part of the chest. Axial skeleton consists of 80 bones and strenum is one of them. Axial skeleton functions to provide protection to vital organs such as brain, heart and lungs. Strenum functions to protect heart.

Answer:

root hairs → 1. absorbs water and nutrients from the soil

vascular tissue → 2. consists of xylem and phloem

chloroplast → 3. the site of photosynthesis inside the cell

stem → 4. holds the leaves up high into the sunlight

leaf → 5. acts like an umbrella to absorb light  

terminal bud → 6. the growing part of the stem

taproot → 7. roots that reach deep into the ground

Explanation:

I have been able to match each term to its correct description.

From the above, we will discover that these are parts of a plant. These parts of the plant enable the plant to carry out photosynthesis and to exist.

The root hairs of the plant absorbs water and nutrients from the soil. When such are absorbed, the vascular tissues help to transport them.

The vascular tissue consists of the xylem and phloem. They  transport fluid and nutrients inside the plant. The vascular tissue is associated with two meristems which are the vascular cambium and the cork cambium. It is at the chloroplast that photosynthesis occur; where light energy is converted to chemical energy.

The stem holds the leaves firmly in order to project it to the sunlight. The leaf absorb sunlight which is needed for photosynthesis. The terminal bud is actually the part of the stem that is growing out. Taproot reach deep down the ground in search of water for the plant.
