Explanation:The concentration of a solution can be given in moles of solute dissolved per kilogram of solvent.
This is known as molality.
(Not to be confused with molarity which is a different measure of concentration.)
Molality is given the symbol m.
molality = moles of solute ÷ mass of solvent in kilograms
m = n(solute) ÷ mass(solvent in kg)
A solution containing 3 moles of solute per kilogram of solvent for example, is said to be 3-molal or 3m.
Answer:
Transport vesicles will not be brought to either the Golgi apparatus or the plasma membrane.
Explanation:
Microtubules forms part of the structure of the cytoskeleton. It is a polymer of tubulins.
Apart from maintaining the cell structure, cytoskeleton plays a role in transportation in a cell.
A Constructive secretory pathway is an exocytosis process found in all eukaryotic cells, in which transport vesicles destined for the plasma membrane leave the trans-Golgi network in a steady stream
A disruption on microtubules will lead to a change in structure of the cytoplasm. It will not be able to perform its function therefore transport vesicles will not be brought to either the plasma membrane or the golgi apparatus.
Some fun fact to me is that you can compare the cell to a factory - I always found it interesting. So the nucleus would be like the CEO, and the Endoplasmic Reticulum (ER) is like an assembly line - it's actually quite similar to a line like this!. And Ribosomes are the workers on this line.

Basic characteristics of Sponges:
Sponges belong to phylum porifera. They are simple multi-cellular aquatic animals. They have pores in their body thats why they look like sponge we use in kitchen. These pores are known as ostia. The body cavity is known as spongocoel, which open to out side through large pore known as osculum. Their body is composed of two layers, choanocyte and pinacocyte. Choanocytes are flagellated cells having spikes which help in movement of water into body and aid in capturing of food particles. The skeleton is made up of calcium carbonate or silica. A jelly like substance called as mesoglea is present between pinacocyte and choanoderm.
<span>General characteristics of Archeocyathans:
</span> The term archeocyathans is a Greek word for "ancient cup". They have a single common ancestor and became one of the planet first reef animals. S<span>pecies of archeocyathans is divided into two classes, six orders, 12 suborders, 120 families and nearly 300 genera. They are associated with carbonate sedimentation.They generally lived in shallow water with photic zone. Their fossils often co-occured with fossils of cyanobacteria. </span><span>These are marine organisms whose fossils record dated back to late Precambrian and early Cambrian period. They are most closely resemble to calcareous sponges. Their structure s are conical or tubular in shape and superficially resembles horn reefs. They have world wide distribution and found in Australia, Antartica, Spain, Cubec, New york and California,</span>
