Why is your body going through physical and chemical changes?
Answer:
(MY) body is only going through chemical changes because of my digestive juices, my saliva, and brain functions.
Explanation:
{MY} body isn't going through many physical changes other than my body slowly breaking down on a nuclear level every day slowly just like everybody else that's why nobody dies of old age, its just the teardown of their body eventaully giving out

In the testes, sperm cells replicate and differentiate in the _________. Question 2 options: urethra septum tunica albuginea seminiferous tubules ductus deferens
Answer:
seminiferous tubules
Explanation:
Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.
why does food get cold but drinks get hot
Answer:
it might be because of the room temperature.
Explanation:
since drinks are colder than the room temperature they will get warmer to be the same as the room temperature and because food is hotter than room temperature it gets colder to be the same as the room temperature. dont quote me on that just a guess
1. What is a wave and where do all ocean waves come from?
Answer:
Wave is a water disruption that causes ripples that can be big or small
Waves occur because of the gravitational pull from the moon.
Answer:
In science, a wave is defined as a transfer of energy. Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. Waves are mostly caused and come from wind.

Butanol was used in the production of:
O Cordite
O Nitroglycerin
O Fizzy beverages
Synthetic rubber
Answer:
Synthetic rubber.
Explanation:
Polymerization can be defined as a type of chemical reaction in which molecules that are relatively small in size chemically combine to form a huge chain of molecules.
Simply stated, polymerization refers to a chemical reaction where two or more smaller molecules react to produce larger molecules of the same network or repetitive structural units.
In polymerization, the relatively small molecules are generally referred to as monomers while the larger molecules they produce are known as polymers.
Butanol was used in the production of synthetic (artificial) rubber through a fermentation process.

cientists think that the position of the nostrils gives modern whales an evolutionary advantage. Which of the following most likely describes how this adaptation is advantageous?
O The nostril position allows whales to obtain air more easily at the surface of the water.
The nostril position allows whales to obtain food more easily at the surface of the water.
O The space lett empty by the migrating nostrils has allowed modern whales to develop gills.
The space left empty by the migrating nostrils has allowed modern whales to develop teeth.
Answer: Its A my friend, how it helps!.
Explanation: I just completed the Test.
The nostril position allows whales to obtain air more easily at the surface of the water is most likely describes the advantage of adaptation.
What do you mean by adaptation?In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.
Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.
Answer:
See the answer below
Explanation:
The advice I would give to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.
If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.
If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

explain the flow of energy of candles
Answer:
The wax vapor catches light and burns, sending a flame high above the wick. Heat from the flame travels in three directions at once by processes called conduction, convection, and radiation. Convection draws hot wax vapors out from the wick and sucks oxygen from the surrounding air into the base of the flame.
Explanation:
Answer:
The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.
What should Brenda do when a patient wants to make payments on an outstanding patient account balance?
Answer:
Brenda should facilitate the patient's resolve to make the payments by ensuring that an effective schedule is worked out with the patient and that the patient is able to stick to the agreed schedule.
Explanation:
Brenda should always make sure that patients are encouraged to make good on their promises to pay for their medical treatment. She should be compassionate with the patient by showing understanding and sharing information on payment terms. She should be very creative in scheduling payments in such a way as to ensure that the patient makes payments as scheduled. She can even work out some fees for late payments to encourage the patient to stick to the schedule.
