List and explain nonspecific immune defenses in plants found in a chaparral
garik1379 [7]

Plants’ nonspecific immune responses includes cell-surface receptors (pattern recognition proteins) which allow them to identify certain patterns characteristic for pathogens.  Activated receptors trigger the production of chemical signals that may initiate both local and systemic defense responses. Sometimes when a plant is affected by infection, it triggers rapid localized programmed cell death to stop the infection further.  When it comes to defense form the herbivores, plants have physical barriers (plant cell walls and their extensions), some antibiotic compounds (phytoalexins), and even enzymes that can defend them.

The Earth is more massive than the moon. How will a person’s weight on the moon compare to their weight on Earth?
Rom4ik [11]

Answer:

The weight of a person on the moon is less, compared to their weight on Earth.

Explanation:

Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.

Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.

EXTRA

The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.

Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.

You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.
