which of the following graphs depict the cardiac cycle of an individual with chronic hypertension in which blood pressure is 140/90?
Continuous blood pressure (BP) more than 140/90 mmHg... lowers the risk of cardiovascular events in those with hypertension.
How does the cardiac cycle impact blood pressure?The arterial blood pressure rises during active ventricular contraction phases of the cardiac cycle and falls during ventricular filling and atrial systole. As a result, there are two different ways to measure blood pressure: systolic while the heart is contracting and diastolic when it is relaxing.
When does the peak pressure during the cardiac cycle occur?The highest active chamber stiffness or elastance (pressure to volume ratio) usually happens after ejection. When left ventricular pressure falls below left atrial pressure, ventricular filling (phase IV) which follows isovolumetric relaxation, begins.

what's the difference between limiting factor and carrying capacity
Limiting factors and carrying capacity are connected to the number of organisms in an ecosystem.
Limiting Factor
A limiting factor is any part of an environment that controls a population within one area. For example, available food is a limiting factor. There is not unlimited food, so it limits how many organisms can survive in one area. Organisms can only survive if there is enough food for them. Space is also a limiting factor because there is only so much space for the population. Overall, any factor that forces the organisms to compete or that limits resources is a limiting factor.
Carrying Capacity
The carrying capacity of an area is the total number of organisms that an ecosystem can safely support. For example, one ecosystem might have a carrying capacity of 5,000 bunnies. This means that the ecosystem cannot sustain more than 5,000 bunnies. When a population begins to near the carrying capacity, birth rate will decrease or death rate will increase. Since resources start to dwindle as carrying capacity is reached, it becomes more difficult for the population to grow.
The limiting factors of an ecosystem create the carrying capacity. For instance, if there is only enough food to feed 5,000 bunnies, then the carrying capacity will be 5,000.
Minha's mother wants to buy curtains for all the windows of their house. She asked Minha to measure the length of the existing curtains which serve as a ready reference while buying the new ones. If an elastic measuring tape is used for measuring the length of the curtains, will Minha get an accurate measurement? Why? Give reason.
If an elastic measuring tape is used for measuring the length of the curtains, will Minha not get an accurate measurement. The length will be reduced. This is due to elasticity.
What is elasticity?This refers to the ability of an object/ material to return to its original shape/length after a stretch.
When an elastic tape is used in the measurement, the length gotten is likely to be inaccurate as the tape will be stretched during the measurement and return to its original length after measurement giving a shortened length.

Why is heredity so important to cells?
Explanation:
Perhaps the most fundamental property of all living things is the ability to reproduce. All organisms inherit the genetic information specifying their structure and function from their parents. Likewise, all cells arise from preexisting cells, so the genetic material must be replicated and passed from parent to progeny cell at each cell division. How genetic information is replicated and transmitted from cell to cell and organism to organism thus represents a question that is central to all of biology? Consequently, elucidation of the mechanisms of genetic transmission and identification of the genetic material as DNA were discoveries that formed the foundation of our current understanding of biology at the molecular level.
Heredity is important to all living organisms as it determines which traits are passed from parent to child. Successful traits are more frequently passed along and over time can change a species. Changes in traits can allow organisms to adapt to specific environments for better rates of survival.
Which of the following statements is true of the production of energy from matter?
The statement that is true of the production of energy is option C: Proteins and lipids generate substantially more ATP energy than glucose, but the body has a harder time breaking them down.
What is energy production in the body?Carbohydrates, lipids, and proteins are the three main categories of fuel molecules that provide energy to humans. These molecules' kinetic, thermal, and other chemical forms are created from their potential chemical energy.
Note that the breakdown of nutrients from the foods we eat by our cells results in the production of energy in the human body. Cellular respiration is the process that releases the energy that has been stored in nutrients. Our cellular processes are then powered by this energy, which keeps us alive.
Hence, one can say that the human body produces the energy required to power ATP synthesis using three different types of molecules: lipids, proteins, and carbs. Although some ATP is also generated in the cytoplasm, mitochondria are the primary location for ATP synthesis in mammals.

The swelling and bursting of the red blood cells isSelect one:a. hemolysis.b. agonal edema.c. a rupture.d. an ecchymosis.
The swelling and bursting of the red blood cells is called hemolysis which is nothing but destruction of red blood cells.
Hemolysis is the breakdown or destruction of red blood cells, which are responsible for carrying oxygen to the body's tissues. This can occur when red blood cells are exposed to certain substances or conditions, such as certain medications, infections, or physical trauma, which can cause the cells to swell and burst. The release of hemoglobin, the protein that carries oxygen in the blood, into the surrounding tissue or fluid can lead to anemia and other health problems, depending on the severity of the condition. Hemolysis can also be caused by underlying health conditions, such as sickle cell anemia or autoimmune disorders, in which the body's immune system mistakenly attacks and destroys healthy red blood cells. Hemolysis can be diagnosed through a combination of physical examination, laboratory tests, and imaging studies, and treatment may involve medications, blood transfusions, or other therapies.

An apple, potato, and onion all taste the same if you eat them with your nose plugged
WHY IS THIS
Answer:without your nose you taste
Explanation:
use book
This is because most of what we perceive as “taste” is due to our sense of smell. Our brain combines the information from both scent and taste to create the overall flavor of food or drink. When we plug our nose, we block our sense of smell and impair the connection between our nasal cavity and brain. This makes it hard to identify the flavor of food, which consists of smell, taste, temperature, texture, spiciness, and so on. Therefore, apples potatoes and onions may taste similar if we eat them with our noses plugged.

Skin cancer may develop in people who have mutations in the excision repair enzymes as a result of unrepaired DNA damage brought on by the sun's UV radiation.
Excision repair involves identifying the damaged DNA and removing it, either as single bases or even as nucleotides. A new DNA strand is subsequently created, using the unharmed complimentary strand as a template, to close the resultant gap. DNA ligase, a specialized enzyme, surrounds a double helix to fix a damaged strand of DNA (seen here in color).
