Match each cell structure with its function. Some structures may not be used. centriole cytoplasm cytoskeleton lysosome ribosome vacuole Stores materials inside the cell Breaks down lipids, carbohydrates, and proteins Helps the cell maintain its shape

Stores materials inside the cell --vacuole

Breaks down lipids, carbohydrates, and proteins --lysosomes

Helps the cell maintain its shape--cytoskeleton

Explanation:organelles are found within a cell.Each organelle performs specific function

1) Centrioles; Centrioles are found in animal cells and they occur in a pair.they help to organize microtubules during cell division

2) cytoplasm;the cytoplasm of the cell is the gel like medium on which reproduction, growth and other metabolic activities takes place.other organelles in the cell are contained in the cytoplasm

3) cytoskeleton; cytoskeleton of a cell consists of microtubules and microfilaments.it functions to influences cell shape, movement of chromosomes during cell Division and provides the internal structure of cilia and flagella

4) lysosomes; lysosomes are involved in digesting substances.they help to break down dead cells.they are capable of splitting complex chemical compounds into smaller sub units

5) ribosomes;they are specialized organelles where synthesis of proteins takes place. they may be attached to other cellular membranes eg the endoplasmic reticulum or they may occur freely distributed in the cytosol.

Vacuole; vacuoles are found only in plant cells.they are bound by a membrane called tonoplast.the vacuole takes in large dissolved substances ,thus it creates turgidity In the cell

i dont know it at allnow im just getting points at this pint

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
