A person is taken to the emergency room at Baptist Hospital vomiting, bleeding and with severe diarrhea. He complained of a headache, shortness of breath and body aches. The doctor quickly checked the composition of the patient’s blood plasma, the light-yellow liquid that carries salts and enzymes, and determined he was severely dehydrated. Thus, causing a severe loss of fluid in the blood and an increase of blood cell concentration. The doctor prescribed intravenous liquids (IV) and rest.
Based on the patient’s symptoms and doctor’s initial prognosis, how does dehydration affect a person’s blood flow and blood pressure? SC.912. L.14.36
The patient’s blood viscosity would increase, causing blood flow to increase and blood pressure to decrease
The patient’s blood viscosity would decrease, causing the blood flow and blood pressure to remain at a stable rhythm
The patient’s blood viscosity would decrease, causing the blood flow to decrease and the blood pressure to also decrease
The patient’s blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase
Answer:
The answer is "The patients blood viscosity would decrease, causing the blood flow to decrease in the blood pressure to also decrease".
The correct answer is: The patient’s blood viscosity would increase, causing the blood flow to decrease and the blood pressure to increase.
What is Dehydration?When the body loses more fluid than it takes in, dehydration develops. It occurs when the quantity of water and electrolytes (such as sodium, potassium, and chloride) that the body need to operate correctly are out of balance.
Numerous internal processes, such as controlling body temperature, lubricating joints, transferring nutrients, and getting rid of waste, depend on water.
Dehydration causes the amount of fluid in the blood to decrease, which causes the concentration of blood cells and other components to rise.
Blood gets thicker and flows more slowly as a result of this rise in blood viscosity, which is caused by an increase in blood cell concentration.
As a result, the blood flow decreases, and the resistance to blood flow increases, leading to an increase in blood pressure.
Therefore, in the given scenario, the patient's severe dehydration would cause an increase in blood viscosity, leading to a decrease in blood flow and an increase in blood pressure.

Which of the following biotic factors is associated with increasing the capacity of the organisms to move across fragmented landscapes? Patch size, connectivity,Patch shape, Distance from other landscape patches
Answer:
connectivity
Explanation:
Natural and anthropogenic alterations affect the landscape. The unmeasurable use of the land for farming, cattle industry, buildings, among many other activities, has caused a severe fragmentation in the original landscape that has been seriously affecting biodiversity.
Fragmentation occurs when a big extension is transformed into many different and smaller patches, separated by another type of cover. You can imagine, for instance, an area used for mono-culturing, which you can see as a homogeneous space of the same texture and color, and small green islands of original vegetation dispersed in this cropped area. These small islands are separated from each other by the crop.
These alterations produce patches or tesserae in the landscape. Patches are relatively homogenous areas with well-defined borders and environmental characteristics very different from those of the surrounding areas. These are like islands. You can think about patches or tesserae as the remaining pieces or units of the original landscape dispersed inside an affected bigger-sized area.
Fragmentation generates a significant loss of physical continuity between the different areas of the original habitat. It might negatively affect biodiversity by decreasing patch sizes, completely isolating them from each other, and increasing the border effect.
Many species can not survive if they are not in the original habitat. Probably they do not find enough food or shelter, or they are very exposed to predation. So they need to stay in the patch. Most of these species are not even adapted to living on the border of the patches. Eventually, fragmented areas can not support some population species that end by dying because they can not survive for a long time in that reduced place. Patches are not suitable to support too many species.
For these reasons, the connection between islands becomes so important. To allow species to move from one place to the other, interact with other species, reproduce, find food, shelter, avoid predation. In other words, survive. Connectivity is how the territory makes possible individuals flow or genetic flow, between the different tesserae.

A pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem. Look at the biomass pyramid to the right. Based on the data shown, how many kilograms of plant matter would be needed to support the other trophic levels in this ecosystem?
Answer:
90,000
Explanation:
A pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem. From the biomass pyramid to the upright ladder, the kilograms of plant matter needed to support the other tropic levels in this ecosystem is 9000 kg.
In ecology, the biomass pyramid is a graphical representation designed to show the quantity of biological or organic matter observed in an organism.
The ecological biomass pyramid starts with the primary producer which is usually a green plant.
Followed by the herbivores(animals that feed) on the green plants. They are the primary consumers. The carnivores are secondary consumers that feed on herbivores. Then the peak of the pyramid is the tertiary consumers which are called omnivores. (i.e animals that feed on plants & animals).The amount of mass consumed by the primary consumer is equivalent to the total amount of mass in the primary consumer. However, as we go up the pyramid, the mass depreciates.
Therefore, we can conclude that the amount of kilograms of plant matter needed to support the other tropic levels in this ecosystem is 9000 kg.

Answer:
nitrogen-fixing bacteria
Answer: A
Explanation:
What direction will the white molecules tend to move?
The population of white molecules will move from left to right , as the concentration of white molecules is lesser on the right side than on the left.
How to explain the informationIn the scenario you described, where the concentration of white molecules is higher on the left side and lower on the right side, the white molecules would indeed tend to diffuse from left to right. This is because molecules naturally move from regions of higher concentration to regions of lower concentration in an attempt to equalize the concentration throughout the system.
As the white molecules move from left to right, the concentration gradient across the system will gradually decrease until equilibrium is reached. Hence, movement of molecules will be from higher concentration to lower concentration.

Answer:
Maintaining a normal blood volume is necessary for blood to be able to adequately reach all of the tissues of your body. When you're very dehydrated, your blood volume can decrease, leading to a drop in blood pressure. When blood pressure drops too low, your organs won't receive the oxygen and nutrients they need. might be what you are looking for but if not i will change it
Explanation:
The production of red blood cells is regulated by a feedback loop involving erythropoietin. In non-disease states, the production of red blood cells is equal to the destruction of red blood cells, thus maintaining sufficient red blood cells to deliver adequate oxygen to the body's tissues. However, when the number of red blood cells decrease and oxygen levels are low, erythropoietin is produced by the liver and kidneys to increase the production of red blood cells. Is this a positive or negative feedback loop
Answer:
Negative feedback.
Explanation:
The production of erythropoietin by the liver and kidneys is a negative feedback because with the production of erythropoietin, our body tends to move to become more stable state. The erythropoietin is produced by the liver and kidneys to increase the production of red blood cells if the quantity of red blood cells are lower than the normal range. If the number of red blood cells are decreases the oxygen level in our body is low that leads to unstable condition of the body but when the concentration of red blood cells increases, the body move towards stability.

Several examples of antisense RNA regulating translation in bacterial cells have been discovered. Molecular geneticists have also used antisense RNA to artificially control transcription in both bacterial and eukaryotic genes. To inhibit the transcription of a bacterial gene with antisense RNA, what sequence might the antisense RNA contain
Answer:
An antisense sequence with complementary to the target mRNA encoded by the gene of interest
Explanation:
An antisense sequence is usually a short RNA sequence specifically designed in the laboratory to bind by complementary to the DNA/RNA sequence of interest (usually a target mRNA) whose expression is desired to be inhibited. When an antisense bind to its target mRNA, the antisense sequence acts to block translation, thereby inhibiting protein synthesis. Moreover, it has been shown that the double-stranded antisense-RNA complexes may also increase the susceptibility of the target sequence to RNase H digestion.
