True or false. All mollusks are cemented permanently to the ground

Answers

Answer:

False

Explanation:

Mollusks are living organisms that can move around often, like mussels and clams, and oysters.

The statement "All mollusks are cemented permanently to the ground" is definitely false.

What are mollusks?

Mollusks may be defined as a type of living organism that has a soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.

According to the context of this question, mollusks also have the ability to move around their surrounding in order to facilitate their survival and interactions with other living forms. The characteristics of mollusks may include a mantle with a mantle cavity, a shell (except where lost), visceral mass, a foot, and a radula. The odontophore is in the mouth of most mollusks and it supports the radula.

Therefore, the statement "All mollusks are cemented permanently to the ground" is definitely false.

how would local residents of a place be affected by changes in the hydrosphere? (please help!!)

Answers

Answer:

Humans have impacted the hydrosphere drastically and will only continue to due so based on population needs. Global climate change, water pollution, damming of rivers, wetland drainage, reduction in stream flow, and irrigation have all exerted pressure on the hydrosphere's existing freshwater systems.

Hope it helps :)

The hydrosphere is needed to support human existence. It provides drinking water, water for agricultural purposes, and food and nutrients from fish and plants.
Without hydrosphere the atmosphere will no longer be able to carry up the evaporated water, as well as pour down the water, leaving the biosphere to die.
It will affect all organisms because they won’t be able to survive with water.
