Answer: Chose which type of mutation that causes a sickle cell anemia.
<h3>Lipoproteins</h3>
Explanation:
Lipoproteins are aggregate molecules of lipids and proteins which carry cholesterol in the blood. Cholesterol binds with water-soluble carrier molecules of the lipoproteins.
Based on their density, lipoproteins are classified as very low density lipoproteins (VLDL), low density lipoprotein (LDL), high density lipoprotein (HDL)
The serum lipoprotein levels are diagnostic markers to detect blood fat levels and are checked in the blood lipid profile tests.
If LDL levels are increased it indicates higher risk for heart diseases like atherosclerosis
If HDL is increased, it reflects a healthy heart and reduces the risk for heart diseases or failure
Around the age of six or seven years, our teeth start to loosen, eventually falling right out. These are what we call milk teeth. Their termination is not a cause for alarm, but rather, a natural process. Soon new teeth replace the ones that are lost. In fact, the deciduous teeth help the permanent teeth erupt in their normal position. Certain of the lower vertebrates, such as sharks and mud puppies, continuously produce new teeth. But most mammals have only two sets. It seems that as you go up on evolutionary scale, there is loss in capacity to replace teeth, scientists say. On the other hand, the teeth become more specialized. For example, in lower organisms, teeth are designed primarily for grabbing and slashing, while in higher animals, they are also adapted for chewing and grinding.
It has been known that in humans the first set of teeth do more than just allow a child to chew. They play a role in stimulating and guiding the growth and development of jawbones and permanent teeth. One of the biggest fallacies is the belief that because deciduous teeth are temporary, they are not important. If a child loses milk teeth prematurely, by accident or because of decay, his jaw and permanent teeth are likely to develop improperly. Prolonged treatment may be needed to set them right.
Another reason for our two sets of teeth is that there is not enough room in a child’s small mouth for the full set of permanent teeth – there are only 20 deciduous teeth, compared with 28 or 32 permanent teeth present in adults.
Hope this helps
Answer:
The correct answer is option c. "adaptive radiation".
Explanation:
The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.
