Answer:
so the body works to maintain homeostasis in response to internal or external conditions
Explanation:
Homeostasis is the process of maintaining a stable internal conditions, Homeostasis keeps internal conditions just right for cell function.
Its like if your hot your body with sweat to cool you down
OR
when your cold you shiver which contracts the things inside of your body so your body contains more heat rather than releasing it
An example of Homeostasis in response to internal conditions is:
when your body produces too much glucose, your body releases insulin to bring the level of glucose down
and when there isnt enough glucose your body releases glucagon to bring up the level of glucose to stable your blood sugar
Homeostasis has been the bodily process that is involved in maintaining the environment of the body. The body works to maintain homeostasis in response to internal and external changes.
What is homeostasis?Homeostasis has been defined as the steady internal environment for the maintenance of physiological processes. This involves the optimization of the variables and carious functions so that equilibrium can be achieved.
The factors involved in homeostasis are pH levels, temperature, glucose, etc. It has been the response of the cell towards the external environment so as to maintain balance. The homeostatic range is important for the proper functioning of the body.
The changes in the internal and external environment affect homeostasis as an increase in temperature in summer leads to sweating and a decrease in temperature in winter leads to shivering. It uses the feedback mechanism to maintain equilibrium.
Therefore, the process of homeostasis is in accordance with internal and external changes.

Tobias found a rock that has a mass of 475kg. He placed it in 2000ml of water and the water rose to 2025ml. What is it’s density?
Given parameters:
Mass of rock Tobias found = 475kg
Volume of initial water = 2000mL
New volume = 2025mL
Unknown:
Density = ?
Solution:
Density is the mass per unit volume of a substance.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
Volume of rock = New volume - Initial volume = 2025 - 2000 = 25mL
Now let us convert the mass to g;
1000g = 1kg
So; 475kg will be 475000g
So;
Density of stone = [tex]\frac{475000}{25}[/tex] = 19000g/mL or 19000g/cm³

Analyze your results. Which type of liquid will prevent the apple from turning brown?
Answer:
Lemon
Explanation:
The process in which the exposed "interior" of an apple becomes/turns brown is caused by enzymatic actions in the apple. This browning reaction occurs in many fruits and tubers (like banana and yam). This process requires oxygen to proceed and hence can be restricted by the presence of an antioxidant. Ascorbic acid is an antioxidant that can assist in countering the effect of the oxygen molecules in this browning.
Lemon contains a good amount of ascorbic acid which can assist in counteracting the effect of oxygen and prevent the browning from taking place.

What is a Virus?A virus is a sub-microscopic organism, which is an infectious agent that replicates only when present inside the living cells of an organism by using its replication machinery. Viruses infect all the life forms, from animals and plants to the microorganisms, such as bacteria and archaea.
Viruses can be stopped from spreading in the host body by destroying the RNA polymerase, this RNA polymerase is responsible for the multiplication of RNA from host DNA in an organism. By prohibiting the activity of RNA polymerase from initiating the replication the multiplication of viruses can be stopped. This RNA polymerase moves along the host DNA and forms new strands for the replication purpose.

The Life Cycles of Stars: How Supernovae Are Formed
It is very poetic to say that we are made from the dust of the stars. Amazingly, it's also true! Much of our bodies, and our planet, are made of elements that were created in the explosions of massive stars. Let's examine exactly how this can be.
Life Cycles of Stars
A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. Over time, the hydrogen gas in the nebula is pulled together by gravity and it begins to spin. As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud's core. The cloud begins to glow brightly, contracts a little, and becomes stable. It is now a main sequence star and will remain in this stage, shining for millions to billions of years to come. This is the stage our Sun is at right now.
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.
diagram of the life cycles of low and high-mass stars
The life cycle of a low mass star (left oval) and a high mass star (right oval).
The illustration above compares the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.
On the right of the illustration is the life cycle of a massive star (10 times or more the size of our Sun). Like low-mass stars, high-mass stars are born in nebulae and evolve and live in the Main Sequence. However, their life cycles start to differ after the red giant phase. A massive star will undergo a supernova explosion. If the remnant of the explosion is 1.4 to about 3 times as massive as our Sun, it will become a neutron star. The core of a massive star that has more than roughly 3 times the mass of our Sun after the explosion will do something quite different. The force of gravity overcomes the nuclear forces which keep protons and neutrons from combining. The core is thus swallowed by its own gravity. It has now become a black hole which readily attracts any matter and energy that comes near it. What happens between the red giant phase and the supernova explosion is described below.

What is the molecule that is related to the glucose ?A molecule like glucose that is related to the glucose is the galactose which is also a sugar.
Glucose is a sugar that plays a vital role in the metabolism of most living organisms. It is manufactured by plants and certain bacteria and protists during photosynthesis. Glucose is the main source of chemical energy for cell functions in organisms from bacteria and plants to humans.
Photosynthesis requires the sunlight with carbon dioxide and water as the starting reactants. When the process completes, photosynthesis releases the oxygen and produces the carbohydrate molecules when the most commonly compound is glucose. These molecules contain the energy molecules that are living things that need to survive.

If you are looking at an object that measures 0.5 mm and the image you see is 10 mm long. Your friend is looking at an object that is 0.1 mm long using the same magnification. What is the size of image does your friend see?
The size of the image seen by a friend has been 2 mm.
What is magnification?Magnification can be given as the process of enlarging the image to a degree unlike the physical and the apparent size. The use of magnification glass has been forming the enlargement of the images or objects.
The magnification can be given as:
m = v/u
Where, m = magnification, v = object height, and u = image height
The size of the object (v) = 0.5 mm
The size of the image seen (u) = 10 mm
The magnification (m) of the image seen by a person has been:
m = 0.5 mm / 10 mm
m = 0.05
The image seen by a friend of the object (u) of 0.1 mm with a magnification (m) of 0.05 is:
0.05 = 0.1 mm/ u
u = 0.1 mm/0.05
u = 2 mm
Thus, the size of the image seen by a friend with the magnification same as the person has been 2 mm.
