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.

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.

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.

What would happen on a hot day if your brain did not receive input that your body was starting to heat up

Karolina [17]

Answer:

The body will overheat

Explanation:

If the brain of an individual does not receive input that the body was starting to heat up on a hot day, the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating.

Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding. Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.

What do you think would happen if a genetic mutation caused a person's digestive tract to have stratified columnar epithelium in

Eddi Din [679]

Answer:

Absorption and secretion would be impossible within the digestive tract.

Explanation:

Epithelium is one of the tissues found in humans. It is classified as either simple or stratified depending on the number of cell layers. Simple epithelial tissues have one layer of cells while stratified have many layers of cells. Based on the shape, epithelial tissues can either be squamous, columnar or cuboidal.

Due to the single-layer of the simple epithelial tissues, they line the walls of secretory or absorptive organs e.g organs of digestive tract. The stratified epithelium is majorly for protective function due to the number of cell layers it possess and not a good type of epithelium for locations where absorption and secretion of substances is common e.g digestive tract.

Hence, if a genetic mutation causes a person's digestive tract to have stratified columnar epithelium instead of simple columnar epithelium, ABSORPTION AND SECRETION of chemical substances, which is a key feature of organs (stomach, intestine) that make up digestive tracts, will be impossible.

Where are ribosomes made?

Bond [772]

Answer:

The answer would be C. This is because the nucleus of a cell is responsible for the creation of ribosomes. Hope this helps you :)

damaskus [11]

Answer:

Figure 3

Explanation:

A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:

- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.

- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.

- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.

- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.
