Answer and explanation;
-All lipids contain carbon, hydrogen, and oxygen. Some of them also contain nitrogen and phosphorus. The four main classes of lipids are fats, waxes, sterols, and phospholipids. Fats are triglycerides.
-The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.
-Lipids are water-insoluble (hydrophobic), and this property is put to great use in the organisation of cells and tissues.
For example; phospholipids are a class of lipids that is amphipathic; that is it contains fatty acid tails that are hydrophobic, and a phosphate head that is hydrophilic. This means the phosphate group will orientate itself towards water and away from the rest of the molecule, and also gives rise to the special properties that allow phospholipids to be used to form membranes.
a) ribosomes on the rough endoplasmic reticulum
mRNA (created by DNA) leaves the nucleus through the nucleic pores, and from there will enter a nearby ribosome since the rough endoplasmic reticulum is surrounding the nucleus. It is there that polypeptides are made and transported in vesicles to the Golgi apparatus because they cannot touch the cytoplasm when still incomplete. Hope this helped.
<span>Herbivores posses different digestive system than that of carnivores. In the course of evolution herbivory evolved with a complex digestive tract. There is no cannine teeth for herbivores. The stomach contains billions of bacteria. The intestine is 27 times longer in length than the length of its body.</span>
Answer:
Explanation:
Diffusion is net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance.
