what might an engineer need to consider when designing a heating/cooling system for a home in a cooler climate?
How might the design differ for a house found in a warmer climate?
An engineer might need to use passive construction when designing a heating and cooling system for a home in cooler climate and hot climates.
The engineers should ensure that he constructs a passive housing system. Windows in the living room must face true south or within 30 degrees of it according to passive design.
Any way of heating or cooling a home that doesn't involve energy input from the occupants or a mechanical device is considered passive heating and cooling.
To use passive heating, all of your doors and windows must be absolutely airtight. You should have double-paned or triple-paned windows since badly built ones will allow the heat from the sun to just flow back out. The ability of the window to retain internal heat and keep out outside air improves with the number of layers of glass.

Questions on The excretory system
The excretory system is a passive biological system that removes excess, unnecessary materials from an organism's body fluids in order to help maintain internal chemical homeostasis and prevent body damage.
The excretory system is what?Organs of the human excretory system enable the elimination of nitrogenous wastes from the body. The kidney, ureter, urinary bladder, and urethra are the primary excretory organs. Blood is filtered through the kidneys, and the result is urine.
The answers are follows
The first claim is accurate since diabetes either results in insufficient insulin production or insufficient insulin use by the body. Without insulin, blood glucose levels rise to an unmanageable level that your kidneys are unable to filter and reabsorb.The kidneys receive oxygenated blood from the heart through the renal artery.We discovered that the concentration of urea may be higher in the renal vein than in the renal artery after fruitless attempts to gauge the blood flow rate through the kidney.Nitrogenous wastes are typically present in the deoxygenated blood that passes through the renal vein.More glucose is found in the renal artery than the renal vein.To know more about excretory system, refer

A rubber ball dropped from a certain height has constant uniform acceleration due to gravity. Therefore, rubber ball dropped from a certain height is an example of uniform acceleration.
Elastic potential energy causes a ball to bounce as it is transformed into kinetic energy, which then brings the ball back up. However, the ball does not get high as in the start, because some of its energy is transferred to the floor or into sound.
And also, as the ball hits the ground, or a table, it changes shape for a split second, even though we don't see it. This also requires energy.
Therefore, we can observe that the height of each bounce is a little less than the previous one. Some of the kinetic energy of the ball is retained, when it strikes the floor but all the other is transformed. It loses a bit of its kinetic energy every time the ball bounces and after that it ceases to bounce after several strikes.

The sentence that best evaluates the student's hypothesis is-
The hypothesis is not supported because the mass of the grape increased in grape juice.
What is mass?A physical body's mass is its total amount of matter. Inertia, or the body's resistance to acceleration (change of velocity) when a net force is applied, is also measured by this property. The gravitational pull an object has on other bodies is also influenced by its mass.
The kilogram is the fundamental mass unit in SI. Although mass is frequently determined by measuring an object's weight on a spring scale rather than a balance scale and directly comparing it with known masses, mass and weight are not the same things in physics. Although there is less gravity on the moon than there is on Earth, an object would still have the same mass.

pongids: a. are incapable of walking bipedally b. can walk bipedally only by holding on to branches with their arms c. are capable of bipedal locomotion, but inefficiently d. are, in fact, habitually bipedal
One of the earliest adaptations made by hominids was bipedalism, and there are several theories as to how the human ancestors acquired it. One of them claims that after a group of our ancestors started living in Savannah habitats, bipedalism emerged (open areas covered with grasses). The Savannah lineages didn't have many trees to climb, so the upright posture let them see predators in the distance. Other lineages remained in the forests, where they could use the treetops and branches for protection and to collect food.
The second theory links the use of tools to the evolution of human bipedalism. The two forelimbs are free to explore the environment, aid in the use of tools, and even gather food while moving because a species does not move on all four limbs.
With this knowledge, we can conclude that bipedalism gave the human race a free arm to build technology and allowed them to move more slowly while walking, among other benefits.

explain importance of water potential gradient and osmosis in uptake and loss of water
Answer:
Mark Brainliest
Explanation:
If the water potential around the plant cell is high, water enters the cell via osmosis. (Movement of water molecules from a region of higher concentration to a region of lower concentration). Hence, the plant cell is turgid (swollen or full of water) now. Having a turgid plant cell is very important as turgidity of a cell prevents the plant from wilting as the cell is firm. Also, a turgid cell pushes the guard cells open (a flaccid cell doesn't as it is limp) and allows gas exchange for photosynthesis and respiration.
Both water potential gradient and osmosis are important for the overall development of plants.
What are the importance of water potential and osmosis in plants?For photosynthesis to occur, plants use water potential to move water to the leaves. The difference between the potential in a specific water sample and pure water is known as the "water potential," which is a measurement of the potential energy in water.
Osmosis aids in preserving the water content of plant cells. It is a technique that enables plants to retain water despite ongoing water loss. It gives the plant body's softer cells a turgidity. Water is absorbed by root hairs from the soil by osmosis. It regulates the movement of water from xylem components to surrounding cells.
