f. Vasoconstriction
g. Increase peripheral resistance
h. Increase salt intake
i. Increase blood volume
j. Increase water reabsorption
Answers
Answer:
a. Decrease water reabsorption : decrease blood pressure.
b. Decrease peripheral resistance : decrease blood pressure
c. Vasodilation : decrease blood pressure
d. Decrease salt intake : decrease blood pressure
e. Decrease blood volume : decrease blood pressure
f. Vasoconstriction : increase blood pressure
g. Increase peripheral resistance: increase blood pressure
h. Increase salt intake: increase blood pressure
i. Increase blood volume : increase blood pressure
j. Increase water reabsorption: increase blood pressure
Explanation:
Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow. This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance. Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows. This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others. Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure. The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs. Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.In your biology class, there was a discussion about climate change. You learned that human activities are changing the composition of Earth's atmosphere, and that levels of greenhouse gases like carbon dioxide (CO2) have been increasing sincepre-industrial times. Your teacher stated that the atmospheric buildup of CO, and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels. One student in your class disagreed. He said that the increase in human populations worldwide is causing the higher level of CO,. His argument is that as people exhale, they release CO, from cellular respiration; more people, more COy. Your class erupted in discussion, and your teacher has asked that you choose a side and research the argument. Working in small groups, create short documentary (3-5 minutes) about how respiration and fossil fuel burning are similar processes. Use data and evidence from peer-reviewed sources to make a claim regarding whether or not one (or both) of these processes can be the root cause of climate change.
Answers
Answer:
Below
Explanation:
While your classmate is correct in that respiration does cause the release of CO2, it's inaccurate to say that it has contributed to climate change, and it's especially inaccurate to say it has contributed to the same extend as the use of fossil fuels.
Let's break it down shall we:
When a human breathes, they release 35,000 to 50,000 ppm (parts per million) of CO2 with every exhale. On average, we breathe out 20,000 times a day. Multiply that by the amount of people on Earth, about 7.8 billion, you get 1.716x10^14 breaths a day. Therefore, you have that times 50,000 ppm of CO2 released. That sure is a lot, however, let's look at how much carbon dioxide is released from coal alone in a day. In general, the world consumes over 8.5 million tons of coal a year, and in the US alone 14,000 tons are burnt in one day. When you burn one pound of coal, around 2 pounds of CO2 is released, as the carbon of the coal mixes with the oxygen requiring it to burn. Therefore, 28,000 tons of CO2 is put into the environment from coal alone (not even including all of the other fossil fuels like natural gas and oil), showing how extensive the CO2 burning of fossil fuels is.
Additionally, I want to address the point of increased human population leading to more CO2 from respiration. Consider this, with more people, there is more need for agriculture. Aka, we need to grow more plants in order to sustain our growing population. Plants grow using photosynthesis which needs Carbon Dioxide to begin. Therefore, as our population grows, the amount of CO2 taken from our atmosphere in order to sustain our population actually shows that growing population doesn't necessarily relate to more CO2 from exhalation overall.
describe how impulse are transmitted across a synapse
Answers
A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.
What are the impulse?Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.
The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

Answers
The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.
Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.
Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

HELP PLEASE! Which of the following courses should a student take in order to become a hydrologist? Choose the two best answers.
statistics
life science
coding
physical science
philosophy
Answers
Answer:
The two best courses for a student aspiring to become a hydrologist would be:
Physical Science: This course would provide a solid foundation in understanding the principles of physics and chemistry, which are essential for studying the movement and behavior of water in hydrology.
Statistics: Statistics is crucial for analyzing and interpreting data in hydrology research. Hydrologists often deal with large datasets and need statistical skills to make accurate conclusions and predictions.
While the other courses may have some relevance or value in certain aspects of hydrology, they are not as directly applicable or fundamental as physical science and statistics.
Explanation:
Answer: Statistics and Physical Science.
Explanation:
Statistics: Statistics is a branch of mathematics that deals with collecting, analyzing, and interpreting data. Statistics is essential for hydrologists because they use data to monitor, model, and forecast water resources and environmental issues. For example, hydrologists may use statistics to estimate water availability, assess water quality, evaluate water management strategies, and identify trends and patterns in hydrological phenomena.Physical science: Physical science is a broad term that encompasses the natural sciences that study the physical aspects of nature, such as physics, chemistry, geology, meteorology, and oceanography. Physical science is important for hydrologists because they need to understand the physical processes that govern the movement, distribution, and properties of water in various forms and environments. For example, hydrologists may use physical science to study the hydrologic cycle, the interactions between water and earth materials, the effects of climate and weather on water resources, and the principles of fluid mechanics and hydrodynamics.Hope this helps, and have a great day! =)

you have isolated an aerobic gram-positive, endospore-forming bacterium that grows well on nutrient agar. to which of the following groups does it most likely belong?
Answers
isolated an aerobic gram-positive, endospore-forming bacterium that grows well on nutrient agar is belong to the group Bacillales.
Bacillus, which means "stick" in Latin, is a phylum of Gram-positive, rod-shaped bacteria and contains 266 identified species. The term is also used to refer to the shape (rod) of other similarly shaped bacteria; the phrase is also used to refer to the class of bacteria to which this genus belongs, which is known by the plural Bacilli. Obligate aerobes, which require oxygen to survive, and facultative anaerobes, which may live without it, are two different types of Bacillus species. If oxygen has been utilised or is present, cultured Bacillus species test positive for the enzyme catalase.
Bacillus can transform into oval endospores and can survive for years in this inactive state. One species from Morocco is said to have had its endospore survive being heated to 420 °C. [2] When nutrients are scarce, endospore development often occurs as a result of bacterial division within the cell wall followed by engulfment of one side by the other. They aren't actually spores (i.e., not an offspring). The genus was initially classified by endospore production, but not all of these species are linked to one another, and many species have been transferred to other genera of the Bacillota. Each cell only produces one endospore. Heat, cold, radiation, desiccation, and disinfectants cannot harm the spores.

Pikas grow thick fur in winter, and their small bodies conserve heat. Kangaroo rats
do not sweat, and oily fur helps them conserve moisture. They get water from seeds.
Predict what would happen if a pika and a kangaroo rat switched environments.
Answers
A pika's adaptation to its habitat includes growing thick fur in winter to conserve heat. In contrast, the desert environment where the kangaroo rat lives is very hot and dry; therefore, its oily fur helps to conserve moisture rather than heat. The pika's thick fur would make it too hot in the desert environment, whereas the kangaroo rat's oily fur would not be sufficient to conserve moisture in the colder environment.
Additionally, pikas get their water from consuming snow whereas kangaroo rats get water from seeds. In a colder environment, snow is readily available, but in the desert, there is no snow. The kangaroo rats might not be able to survive in colder environments if they do not have access to water, and the pika might not be able to survive in the desert without access to snow.
Therefore, it is likely that the adaptations that allowed the pika and the kangaroo rat to survive in their respective environments would make it difficult for them to survive if they were to switch habitats.
