Q23 Which of the following describes the correct relationship between heart sounds and blood pressure? A.Systolic blood pressure is associated with the first heart sound. B. Systolic blood pressure is associated with the second heart sound. C. Diastolic blood pressure is associated with the first heart sound. D. Diastolic blood pressure is associated with the second heart sound.

Answers

Answer 1

Answer:

diolostic blood preasure is associated with the second heart sound

Explanation:

Korotkoff sounds are the sounds heard by the health professional who measures the blood pressure with a blood pressure monitor and a stethoscope placed on the patient's brachial artery.

Korotkoff described five types of noise:

* The first sound is a snap corresponding to the systolic pressure. The noise is clear, repetitive on at least two consecutive systoles.

* The second sound is a soft whisper, more or less prolonged, audible between the systolic pressure and the diastolic pressure.

Describe the difference between a chemical and an electrical gradient. What's an electrochemical gradient? Do you think an electrochemical gradient can have conflicting component gradients?

Answers

Answer:

1) The difference between chemical gradient and electrical gradient is that chemical gradient refers to the change in concentration of an ion or molecule in a solution across a biological membrane while electrical gradient refers to the existence of an electrical potential difference that leads to the movement of charged ions towards or away from the electrical potential

2) Electrochemical gradient is the charge and ion concentration difference across a biological membrane

3) No because electrochemical gradient which consists of both an electrical and chemical gradient have a complementary effect in determining the level of the electrochemical gradient.

Explanation:

The electrochemical gradient is the gradient of the electrochemical potential and is usual for a positive and negative ion that can move across the membrane.

What is the electric gradient ?

The gradient is made of two parts that are chemical which is different in solutes that can move across the membrane and have an electrical component that shows difference in changes across the membrane.

The electrostatic gradient is a potential used in an iron that can be used across the membrane. Due to unequal concertation of ions, they will move across the simple diffusion.

The electrochemical has potential in electroanalytical industries as batteries and fuels. The gradient has contrasting components as change across the membrane.

Suppose that an unusually high degree of aurora kinase activity is observed in the cervix. What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage

Answers

Answer:

The division of cervical cancer cells will be inhibited  

Explanation:

Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.

Explanation:

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? A. In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant. B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells. D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.

Answers

Answer:

Option C

Explanation:

Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

Elysia chlorotica which is a form of sea slug feeds on a specie of the genus Vaucheria (an algae) and then retains only the chroloplasts of these algae which it uses for its own supply of energy.

The algal partner in lichens is the photosynthesizing partner. It produces food and this is its role in the relationship. The fungi are heterotrophs and cannot photosynthesize food. The fungi contribute to the relationship my absorbing mineral and water and presents it to the algae.

Answer:

Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

Q2. A student places peaches into a pure water solution
Give two differences you would expect to find in the water

Answers

Answer:

The correct answer -  peaches will swell.

Explanation:

In the hypotonic solution, solution has a higher water potential than that of the cell of peach, so water will move from a region of higher water potential to a lower water potential across via osmosis.

Peaches have more solutes than pure water as it has higher sugar content than pure water. Hence, endosmosis will take place which means the water molecules will move from outside to inside of the peaches through wall of peaches takes place. Due to this, peaches will swell eventually.

Thus, the correct answer -  peaches will swell.

Which sustainable practice is paired correctly with its impact on the environment? Using bamboo results in an increased use of forest trees. Practicing contour plowing results in a need for more land. Setting irrigation systems to run longer results in a reduction of water use. Building more wind farms results in a reduction of fossil fuel use.

Answers

Hey there! I'm happy to help!

Using bamboo results in an increased use of forest trees. Bamboo is a grass, not a tree. I don't see how using more bamboo would increase your usage of trees. This option is incorrect.

Contour plowing is when your plow around the contour lines (which are basically like elevation lines) of a hill or slope. This actually reduces soil erosion and lasting effects of natural storms and disasters, so it does not result in a need for more land. This option is incorrect.

Setting irrigation systems to run longer results in a reduction of water use. Irrigation is a system of  watering, so you need water for it. It would not reduce water use. This option is incorrect.

Building more wind farms results in a reduction of fossil fuel use. If you are getting your power from renewable resources like the wind or the sun, you will not need to use as many fossil fuels, and this would reduce their use. This option is correct.

Have a wonderful day!

The practices that aid in economic, human and ecological dynamism and health is called sustainable practices. This procedure helps in conservatively preserving the limited sources.

The correct pairing is:

Option D. Constructing more wind farms results in a decrease in fossil fuel usage.

The practices can be explained as:

Using too many bamboos will result in the degradation of lands and increased soil erosion. It will not affect the usage of other forest trees.

The method of agriculture practice in which the ploughing is done near the contour lines is called contour ploughing and does not need much land also helps in reducing soil erosion and disasters.

The irrigation system conserves water and is a beneficial technique of watering the agricultural lands with an efficient amount of water.

Wind energy generates more energy and power which is a renewable source compared to fossil fuels and reduces the use of petrol, diesel and coal.

Therefore, option D is correct.

Emigration

Explanation:

If there is a large number of deaths, then the population would move onto another area to find a mate, more food, and to be together to protect themselves from danger

The component of population that will most likely increase with a high death rate would be emigration.

When the death rate shoots up in a particular environment due to certain factors, organisms are bound to emigrate away from such environment to avoid death from reaching them.

It is a natural instinct of every living organism to respond to stimuli. A high death rate is a stimulus that organisms would want to move away from.

Point mutation is the alteration of the single nucleotide base in the sequence. Insertion mutation is not a type of point mutation. Thus, option D is correct.

What is point mutation?

A point mutation is a modification and change in the base of the genetic sequence. In this type of mutation, only a single nucleotide base is altered. Point mutations are categorized as transition mutations and transversion mutations.

Silent, Nonsense, and missense are the transversion type of point mutation. In this mutation, the purines get altered by pyrimidines and vice versa. On the other hand, insertion mutation is the frameshift mutation.

Why might the carrying capacity for humans in the United States change if Americans ate more plant products than animal products? Feeding higher on the food chain would make more energy available for humans to assimilate. Consuming plant products would provide less energy because they are generally less digestible than meat. Eating producers would make available about 10 times more energy than eating primary consumers. A diet made up of more plant and fewer animal products would decrease the amount of energy available in food sources.

Answers

Answer:

The correct option is:Food producers would make approximately 10 times more energy available than primary consumers.

Explanation:

Diets based on sugars, carbohydrates, fibers, proteins and vegetable fats (that is, with the increased consumption of fruits and vegetables) have much less complex structures than the protein in meat, so much more energy is obtained and easier and faster than vegetables.

A clear example is that carbohydrates have a digestion that lasts between half an hour and an hour, while meat takes at least an hour and a half to digest.

Meats are complex protein structures with primary, secondary and tertiary junctions that must be digested and corrupted with gastrointestinal enzymes, whereas the carbohydrate carbohydrates of fruits and vegetables already begin their digestion in the human mouth thanks to alpha amylase.

The faster the digestion, the faster the energy is assimilated in the form of glucose, and the energy currency that is ATP is greater in diets rich in carbohydrates like the one we are writing, based on fruits and vegetables.
