Growing plant roots can exert stress or pressure on rock. Although the process is physical, the pressure is exerted by a biological process (i.e., growing roots).
Burrowing animals can also move rocks which hit against each other; hence leading to weathering

Biological processes can produce chemical weathering, for example where plant roots or microorganisms produce organic acids which help to dissolve minerals. Microbial activity breaks down rock minerals by altering the rock's chemical composition, thus making it more susceptible to weathering.

Garrett notices a small island has formed off the coast of his hometown in Florida. Which of the following best describes what c

Snezhnost [94]

I would say either the first, second, or fourth answer; waves have a very strong impact on the movement of sand and other particles under the water. Erosion of particles off an island are similar in this case.
It wouldn't be anything about a tropical storm; it's no where in the question and we don't know how many storms Florida has or how strong they are.

Active and passive immunity involves all of the following except receiving mother's antibodies through breast-feeding. exposure

Bingel [31]

Explanation:

Immunity is the ability of an animal to resist infection.

There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.

Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.

ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.

NATURAL ACQUIRED IMMUNITY

when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.

During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.
