<u>Coquina</u> is the sedimentary rock is made up of pieces of shells.
Two types of sedimentary rock: Clastic and chemical sedimentary rocks
Explanation:
Coquina is the sedimentary rock formed by fragments or pieces of shells of marine animals like mollusks, brachiopods, trilobites and certain invertebrates.
The shells of marine animals are fragmented due to abrasion and mechanical degradation and sorting by the wave action and chemicals present in the sea water and gets transported which then sediments to form rock structures called coquina. The shells mostly contain calcium carbonate.
Chalk is the sedimentary rock formed b the fossil shells fragmented from foraminifers. This is a more powdery type of limestone.
Depending upon the type of sedimentation, sedimentary rocks are of three types:
Clastic – Made from sedimentation of clastic (pieces from broken rocks) through the processes of mechanical weathering and lithification (cementing and compacting). sandstone, conglomerate
Chemical – Made from evaporation of water and precipitation of materials which were previously dissolved in a solution. Example: Rock salt, dolomite
Organic – Repeated accumulation and sedimentation of organic matter or remains from plant and animal sources like bones (calcium deposits). Example: coal.
Answer:
The difference between the microfilaments, intermediate filaments, and microtubules are stated below.
Explanation:
- They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
- They have a diameter of about 7 nanometre.
- They help in cellular movement.
- They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
- They have a diameter which ranges from 8 nanometre to 10 nanometre.
- They have structural function and are required to maintain the cell shape and organelle position.
- They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
- They have a diameter of about 25 nanometre.
- They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
Genome sequencing test, they compare the genome of the child with the suspected father
Answer:
A.when it reaches the top of its flight
Explanation:
This theory is base on gravitational potential energy which state that potential energy in an object increases as weight and height increases.
the amount of potential energy stored by an object depend s on the mass and height.
