Answer:

selective and differential medium .

Explanation:

Based on the information provided within the question it seems that this type of medium would be referred to as a selective and differential medium . This is because such high NaCL levels are designed to stimulate and allow selective bacteria to grow, while also differential media because the fermented sugar is giving off a yellow halo which allows for the differentiate between the bacteria.

Given that our model finch population is capable of rapid evolution in response to a changing environment, explain why you think
SIZIF [17.4K]

Darwin's finches are a traditional illustration of an adaptive radiation. Their ancestor came on the Galapagos Island about two million years ago. With time Darwin's finches have developed into fifteen different species separated on the basis of beak shape, body size, and feeding and song behavior.  

The population of finches possesses the tendency of evolving rapidly in response to a changing environment. However, they can also get extinct in condition if the weather fluctuates too briskly between the dry and wet seasons. This would most likely take place due to the immigration of genes and mutations within the genes that are conducted on to the next generations.

Arrange the order of events for the internalization of LDL particles into cells:
ElenaW [278]

Answer:

The correct answer is "5-1-3-2-4".

Explanation:

Internalization of LDL particles into cells, is needed to form the intracellular vesicles known as endosomes. The order of events that allow for this process are:

5) LDL receptors migrate to the cell surface and cluster in clathrin-coated pits. Clathrin acts directing the receptors to the cell membrane region where endosomes are formed.

1) A combination of cholesterol and apolipoprotein binds to LDL receptors and becomes internalized as endocytotic vesicles. Once the receptors are in the proper cell membrane region, cholesterol and apolipoprotein are bound and internalized.

3) Several endocytotic vesicles fuse to form an endosome.

2) The environment of the endosome becomes acidic, which causes the LDL to dissociate from its receptor; additionally, the endosome fuses with a lysosome. LDL should be dissociated from its receptor since it is going to be degraded in the following step.

4) The LDL particle is degraded by the lysosome. This takes place after endocytosis, when LDL particles are transported into lysosomes once they are fused, cleaving the cholesterol esters into cholesterol and fatty acids.
