What are some possible future changes in the global climate?

Ugo [173]

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.

If blood pressure is too high what should homeostatic regulation do

Anastasy [175]

Homeostasis is one way our bodies maintain its parameters within the normal range of values. We can say that it is key to life. When homeostasis fail, it can lead to diseases like hypertension and diabetes. In homeostasis, there will be stabilization of blood pressure as well as maintenance of its steady resting state. Take this scenario as an example, if a person exercises, there will be an increase of the heart rate, which will also result to higher blood pressure. The process of homeostasis will then accommodate the body through different mechanisms to make the decrease of the heart rate possible and at the same time reduce the high blood pressure. It is through homeostatis by which the normal body functions are maintaned in order to sustain life.

Silent or missense mutations are small-scale mutations that occur when

Andrei [34K]

Answer:

c. a single nucleotide is substituted with no effect

on the amino acid sequence.

Explanation:

silent mutations occur when the change of the dna

sequence within protein - coding portion of a gene

does not affect the sequence of amino acids that

make up the protein. this change typically takes

place at the third position of the codon also known

as the wobble position.

For years, scientists have known that the major components of the plasma membrane were lipids and proteins. Which model best des

suter [353]

B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.

Explanation:

The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.

According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
