Scientists are trying to engineer non-legume crop plants, such as corn, wheat, and rice, to form symbiotic relationships similar

to the legume-Rhizobiumrelationship.
But this has proven to be a very difficult task. At each step of nodule formation, plant genes must be expressed that enable the plant to respond appropriately to the bacteria. For a non-legume plant to form a symbiotic relationship with rhizobia, it would need to be engineered with the right genes and then express those genes at exactly the right time.

In this activity, you will identify the steps of nodule formation in the legume-Rhizobium relationship. In addition, you will indicate what the products of genes added to a non-legume plant would need to do in order to carry out each step.
The flowchart below illustrates the steps involved in root nodule formation. The first step has been filled in to get you started. Complete the rest of the chart.
First, drag the white labels below the images, indicating what happens at each step.
Then, drag the blue labels to the blue targets, indicating the plant gene functions that must be active at each step.

d) extend infection thread into cortex.

e) Infection thread releases rhizobia inside cortex cells.

f) allow infection thread to rupture.

marissa [1.9K]

Answer:

Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.

IN YOUR OWN WORDS what is the definition?
sweet-ann [11.9K]

Answer:

Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes.

Anaphase is the stage of mitosis and meiosis in which the chromosomes move toward the poles of the spindle.

Telophase is the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.

Cytokinesis is the division of cells after either mitosis or meiosis I and II.

In-s [12.5K]

Answer:

This is an example of Harrison's central nervous system working closely with his autonomic nervous system to give him energy and awareness to escape.

Explanation:

Harrison interprets the presence of the group of teenagers as an imminent danger and so he is on the run, which corresponds to a set of reactions that are triggered in the human body when a danger is around. At this point, the central nervous system and the subtonic nervous system are working together to get the adrenaline in Harrison's body to rise to a level that allows him to escape the group of teenagers. The central nervous system was then responsible for receiving and processing information that indicates to Harrison that he may be in danger.  On the other hand, the autonomic nervous system is responsible for regulating the body's involuntary responses, being responsible for controlling various vital functions and at this time for the release of adrenaline in response to the dangerous situation.
