Answer:
Explanation:
Vesicles have multiple functions, and they primarily store, transport, or digest cellular products and cellular waste. Because they are separated from the cytosol of cells, their internal environment is completely different from that of cells. For this reason, vesicles can digest cell machinery and recover cellular material. In order to transport substances into or out of cells, vesicles fuse with cell membranes and release or absorb inclusions from outside the cells. There are four main types of vesicles. The vacuoles are vesicles that mainly contain water. They are present in plant cells. They transport water into and out of the cell. Lysosomes are vesicles found in eukaryotic cells. They are involved in cell digestion. It can also be used to recover damaged organelles, which work primarily with the endoplasmic reticulum and the Golgi apparatus. They transfer molecules such as proteins and fats between the two organelles, which are the fourth major type of vesicles that contain substances that need to be excreted from cells, most commonly they contain waste.
<em>The well-defined risk factors for AD include inflammation, accumulation of reactive oxygen species (ROS), mitochondrial damage, genetic factors, cerebrovascular disease, brain trauma, and age-related sex hormone loss in men and women, and all of these risk factors can be targets for the development of new drugs for AD.

<em>In Alzheimacy, we classify the drugs or targets for Alzheimer’s treatment according to the currently known neuropathologic features of AD. Signature neuropathological changes in AD include acetylcholine deficiency, glutamate excitotoxicity, amyloid plaques, intracellular neurofibrillary tangles formed by tau-protein precipitates, as well as massive loss of neurons.</em>

The given statement is false, as Paleolithic people thrived in the groups of 20 to 30 individuals.
At the time of Paleolithic, the hominins gathered together in brief societies, like bands, and survived by fishing and gathering plants, scavenging or hunting wild animals. The Paleolithic era is featured by the application of knapped stone tools, however, tools made up of woods and bones were also used by humans at that time.
The plasma membrane maintains homeostasis in the cell by keeping cell contents in and foreign material out, and by providing controlled avenues for the transportation of fuel, fluids and waste.
Answer: specialized service
Explanation:
An economy experiencing high interest rates will have to reduce investment generally, BECAUSE higher rates increase the BORROWING and demands that ONLY investments with prospect of HIGHER RETURNS (i.e PROFITABLE) should be considered.
Thus, all options are profitable EXCEPT specialized services, as they would be considered a luxury (too costly)
The true answer of your question is :
OH : HYDROXYL GROUP
NH2 : AMINO GROUP
CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )
COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.
I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
