Changes in internal body temperature are maintained by various systems in the body that maintain balance between the body and the external environment. Homeostasis can be defined as the biological phenomena that occur within the body to resist changes within it.
Negative feedback resists changes in the body caused by changes in external conditions. Some changes may occur in your body to stabilize it.
How does the body maintain homeostasis through negative feedback? Maintaining homeostasis through negative feedback is a constant activity throughout the body. The human body regulates body temperature through a process called thermoregulation. This keeps the body temperature within a certain range even if the ambient temperature changes significantly.
Can the human body maintain normal temperature?
The human body is able to maintain a normal temperature despite large fluctuations in outside temperature. Depending on the situation, you can experience 1 or 2 changes.

(a) Organelle responsible for detoxification of alcohol in all three samples:
Smooth endoplasmic reticulum
(b) Lysosomes remove the damaged part of organelles.
(c) Steps involved are:
Autophagy is the process which allows body to break down and also reuse old cell parts so that cells operate efficiently. It's a natural cleaning process that begins when cells are deprived of nutrients.
Smooth endoplasmic reticulum helps in detoxifying poisons and drugs in the liver.
Lysosomes are the vesicles that digest excess or worn out organelles, food particles. The membrane surrounding a lysosome prevents the digestive enzymes from destroying the cell. It is an acidic, membrane-bound organelle .The degradation is carried out by hydrolytic enzymes present within the lysosome.
Process by which old organelles and malfunctioning cellular parts are removed from a cell is called Auto phagocytosis. Initially, they are enveloped by internal membranes that then merge with lysosomes

Explanation:
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.

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.

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.

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 reduction division and an equatorial division make up meiosis. To create gametes, meiosis I and meiosis II are necessary.
Meiosis II resembles a mitotic division, whereas meiosis I is a special cell division that only happens in germ cells. Meiosis, which decreases chromosome counts from diploid to haploid, and conjugation (fertilisation), which restores the diploid state by joining two haploid cells, are the two opposing processes that make up this. Chromosome segregation and recombination are the two processes that meiosis uses to create variety. As in mitosis, sister chromatids (the two halves of a duplicated chromosome) still need to be separated. The homologous chromosomes, which an organism acquires from both of its parents and are similar but not identical, must also be separated.
