Which advancement in technology has helped cut down on Waste?
A. Raising pigs on farms
B. Nuclear power
C. Electronic storage of files
D. Disposable milk cartons
C. I think because then you don't need so much paper waste. It cuts down on so much wasted paper
Answer:
C. Eletronic storage of files
Explanation:
The pigs on the farm generate a lot of waste like manure and excrement residues left on the ground by these animals.
Nuclear power still produces radioactive waste (liquid, solid, gas and biological waste).
Replacing paper with electronic files, in turn, drastically reduces the amount of waste, as no large physical space or bulky material disposal will be required, as with paper files.
Disposable milk cartons can facilitate recycling processes, but do not necessarily reduce the amount of waste from these materials.
Given these statements, it can be concluded that the correct alternative, which shows a greater reduction in waste is C.

describe the action of the tricuspid valve when the ventricle is full
It prevents backflow of the blood
ExplanationBlood enters from the right atrium to the right ventricle through the tricuspid valve also called right atrioventricular valve. Ventricles are filled during diastole (relax) period and blood leaves the ventricle during systolic (when the ventricle contracts) period. During systole, this tricuspid valve closes and prevents the backward flow of blood into the right atrium. This causes all blood to move towards the pulmonary arteries.
The tricuspid valve closes when the ventricle is full, preventing backflow of blood due to increased pressure from the contracting ventricle. This action ensures the directionality of blood flow through the heart. In the second phase of ventricular diastole, the tricuspid and mitral valves open allowing the atria to refill the ventricles.
Explanation:When the ventricle is full, the action of the tricuspid valve is to close. This closing action happens due to the contraction of the ventricle muscle that increases the pressure of blood within the ventricle chamber causing the blood to flow back towards the atrium. This backflow leads to the closure of the tricuspid valve in a process known as isovolumic or isovolumetric contraction.
The tricuspid valve, a one-way membranous flap of connective tissue between the atrium and the ventricle, functions to maintain unidirectional blood flow through the heart, specifically on the right side. As the pressure drops within the ventricles during the second phase of ventricular diastole (also known as late ventricular diastole), blood flows from the major veins into the relaxed atria and from there into the ventricles when the tricuspid and mitral valves open.

If you were a cancer researcher working on a cure, would you want to design a chemotherapy drug that would speed up the cell cycle or slow it down? Why?
Yes, I would think of formulating this treatment to slow down the cell growth.
ExplanationIn a cancer patient, the cell cycle is disturbed because it undergoes division very rapidly, leading to the production of unwanted and uncontrolled growth of cells. For the treatment, it would be a better option for the researcher to formulate a anti-cancer agent that slows the cell cycle. Because if the growth of the cell is slowed, the tumour (unwanted and uncontrolled cell growth) will regress and thus more chances of recovery of the patient will be there.

Which of the following is an example of passive transport of materials through the cell membrane
A) Pinocytosis
B) Interphase
C)phagocytosis
D)diffusion
Diffusion is an example of passive transport of materials through the cell membrane. Therefore option D is correct.
Passive transport is the movement of substances across the cell membrane without the use of energy. It occurs along the concentration gradient, which means that substances move from an area of higher concentration to an area of lower concentration.
Diffusion is a type of passive transport where molecules or ions move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This process occurs spontaneously and does not require the cell to expend energy.

How is the theory of evolution an example of a scientific theory?
Scientific method is an empirical method of knowledge acquisition, involving careful observation, formulating hypotheses based on such observations, testing deductions drawn from the hypotheses, and refinement or rejection of hypotheses based on the results of the tests.ext we have to know what “theory of evolution” we’re talking about. Let’s begin with the theory proposed by Charles Darwin in the Origin of Species.
I don’t know what “No assumptions here” in the question details is supposed to mean. Making hypotheses is part of the scientific method. Maybe it means that a hypothesis is assumed subject to verification, while an assumption is an axiom not subject to test. The scientific method makes testable hypotheses but never makes firm assumptions.
Darwin made a lot of observations. Then he made two hypotheses:
The observed variation among individuals can accumulate to produce all the differences we observe among species.
The effect of these variations on the ability of a living entity to survive and reproduce preserves some variations and eliminates others.
The heritability of variations was essential to the theory, but it was an observed fact, not an assumption or a hypothesis.
Match each major blood vessel
Pulmonary Artery: Carries deoxygenated blood from heart to lungs
Pulmonary Veins: Carries oxygenated blood from lungs to heart
Inferior Vena Cava: Carries deoxygenated blood from inferior body to heart
Coronary Arteries: Carries oxygenated blood to heart tissues
Answer:
Pulmonary artery conducts deoxygenated blood from the heart to the lungs.
Aorta mediates oxygen-enriched blood away from the heart.
Inferior vena cava conducts deoxygenated blood from the lower body to the heart.
Coronary artery branches from the aorta and offers oxygen to the muscles of the heart.
Explanation:
Pulmonary artery transports deoxygenated blood from the heart, it is also the specific artery found in the circulation system, which transports deoxygenated blood. When the blood goes inside the lungs it picks up oxygen and goes back to the heart with the help of a pulmonary vein.
The aorta refers to the biggest artery found in the human body. When the blood is pumped upwards through the left ventricle, then it goes via the aorta and then gets distributed to the other body parts.
The inferior vena cava transports deoxygenated blood from the lower limbs of the body, on the other hand, the superior vena cava transports blood from the upper limbs and head of the body.
The heart gets its blood supply through the coronary artery. There are two prime coronary arteries, the right and the left coronary artery that gets separated even further into small arteries.

Why salt affects blood pressure
Salt makes your body hold on to water. If you eat too much salt, the extra water stored in your body raises your blood pressure. So, the more salt you eat, the higher your blood pressure.
Salt affects kidney delicate balance of fluid and increases blood pressure.
ExplanationKidneys exclude the unwanted fluid from the body by filtering the blood. The sodium and potassium ions play their role to get extra water from the blood to urine collecting channels which then lead this water or fluid to the urinary bladder. So, eating the more salt increase these ions which wreck the delicate balance of filtration.
The more salts in the body also result in a higher blood pressure because of holding more water in the blood than the kidney filtrate channels.
A student empties the water out of a glass. The student observes that small droplets of water remain stuck to the glass. Which two properties of water explain the students observation?
The phenomenon of small water droplets remaining stuck to the glass despite emptying can be accounted for by the properties of cohesion and adhesion in water. Cohesion makes water molecules stick together forming droplets, whereas adhesion makes these droplets stick to the glass walls.
Explanation:
The student's observation of small droplets of water remaining stuck to the glass can be explained by two properties of water: Cohesion and Adhesion. Cohesion is the property of water that makes its molecules attracted to each other, causing them to stick together and form droplets. Adhesion is the property that allows water molecules to be attracted to other substances, in this case, the glass, allowing it to stick to the glass walls.
For example, when the student empties the glass, the cohesion property makes water molecules stick together, thus forming small droplets. Meanwhile, the adhesion property causes these droplets to stick to the glass. Together, these two properties explain why droplets of water remain in the glass after it has been emptied.

ANSWER CHOUCES: A) stores chem. energy for the cell to use at later time B) releases chem. energy for cell to use immediately C) absorbs heat, which prevents the cell from overheating D) Removes a metabolic poison from cell
your correct answer would be A
The action of ATP is useful to the cell is stores chemical energy for the cell to use at a later time. The correct option is A.
What is ATP?A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme that transfers energy to cells by releasing its phosphate groups when it interacts with enzymes like ATP triphosphate.
When the cell needs energy, ATP can be taken out and used to fuel processes or stored for use in later ones. Animals use ATP to retain the energy released during meal digestion. ATP produces additional ATP whenever a muscle cell needs energy to contract. ADP is produced by the hydrolysis of ATP. The mitochondria get ATP once it has been phosphorylated.

arrange the sequence of steps in the development of heart failure?
This is the correct sequence of steps in the development of heart failure.
1. Fat deposits build up along artery walls
2.Blockage in artery obstruct blood flow and can cause heart attacks
3.Blood pressure increases and cardiac muscles thicken
4.Heart pumps blood less efficiently
5.Oxygen delivery is reduced and heart failure occurs
Answer:
The correct order is shown in the attachment below.
Heart attack or myocardial infarction is a medical situation which occurs when there is a decrease in the flow of blood towards the heart.
It usually starts with the deposition of substances like fats, cholesterol, et cetera which leads to the formation of plaque in the artery (especially those which feed coronary arteries).
The plaque or blockage reduces the flow of blood towards the heart.
As a result, the heart starting contracting more vigorously which increases the blood pressure and thickens the cardiac muscles.
With time, the efficiency of the heart decreases due to which less oxygen is reached to the heart and ultimately, a person experiences a heart attack.
