Answer:The tendency to maintain a stable, relatively constant
Explanation:
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
what is the relationship between kinetic energy and speed
Answer:
The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
KE = 0.5 • m • v2
where m = mass of object
v = speed of object
That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
The kinetic energy of an object is a function of its speed.
More specifically, the kinetic energy of an object is directly proportional to the square of the speed of the object.
Mathematically, the relationship between the 2 quantities can be represented such that:
Kinetic Energy = 1/2 x mass x velocity^2
Velocity refers to the speed in a particular direction.
Thus, for a 2 fold increase in speed, the kinetic energy of an object increases in 4 folds.

Plzzz help it's due today ik I'm dumb but please help me
Answer:
a. As a container of confined gas is heated, its molecules increase in kinetic energy and push the movable piston outward, resulting in an increase in volume.
B. When you heat them,you essentially give them kinetic energy which increases their speed and hence the distance between molecules increases implying that interatomic forces decreases,leading to change in state from solid to liquid
C. When the gas is heated the particles gain kinetic energy which makes them move faster. This means they collide with the walls more frequently and with greater force and so the pressure increases.
D. Both the increase in pressure and the decrease in temperature cause the volume of the gas sample to decrease. Since both changes are relatively small, the volume does not decrease dramatically.
E. When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
F. Cooling slows the velocities of the He atoms, causing them to behave as though they were heavier. 6. Both the temperature and the volume are doubled for this gas (n constant), so P remains constant. (a) The number of collisions per unit area of the container wall is constant.

Explanation:
You are studying natural selection in a population of small marine invertebrates called isopods that live on pink corals. In this population, isopod body color is controlled by one gene with alternate alleles A and a. Isopods can be red (AA), pink (Aa), or white (aa); body size is controlled by another gene with alternate alleles B and b, and they can be large (BB or Bb) or small (bb). A new predator arrives on the reef that is extremely good at preying on isopods that are large and stand out against the corals on which they live (i.e., red or white individuals). Over time, which genetic individuals would you predict would become more abundant in the population with each subsequent generation?
Answer:
Aa, bb
Explanation:
Recall that this question calls our attention to the theory of evolution as postulated by Charles Darwin. Species that are well adapted to their environment are more likely to survive, reproduce and pass on these favourable characteristics to their offspring.
In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.

so e.coli have mitochondria and undergo cellular respiration?
Answer:
No
Explanation:
E. coli are prokaryotes, meaning they do not have membrane-bound organelles like mitochondria.
However, they do perform respiration to produce the energy needed for cellular processes. They can perform both aerobic respiration (in the presence of oxygen) and anaerobic respiration (in the absence of oxygen).
Since they don't have any membrane-bound organelles, these processes take place in the cytoplasm

Which of the following is an example of diffusion?
A water freezing into ice
B sugar dissolving in a glass of water
C rain falling from the sky
D a stone sinking to the bottom of a lake
A sugar cube is gently dissolved in a glass of still water. Diffusion is the process by which water molecules and sugar molecules interact. By swirling the water with a spoon, we can hasten the diffusion. Thus, option B is correct.
What is the diffusion?Due to the motion of the sugar molecules around the water molecules, sugar dissolves in water. Overall, it exhibits a diffusion mechanism as sugar atoms mix with water atoms.
Sugar will dissolve in water when added to it with a stirring motion. Diffusion is to blame for this, as the sugar will flow down a gradient of concentration.
Diffusion data from sugar solutions, or solutions with no polymer present, suggested that a free water behavior should only be anticipated after a bilayer has covered the sugar molecule.
Therefore, sugar dissolving in a glass of water is an example of diffusion.

The capsid of a virus protects the virus from the external environment What structure is this similar to in a plant cell?
A.Cell wall
B.Cell membrane
C.Vacuole
D.Ribosome
Answer:
The answer would be the cell wall
Explanation:
B is not correct because a cell membrane is a semipermeable membrane surrounding the cytoplasm of a cell.
C is wrong too because a Vacuole is a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
And D is false because a ribosome is a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.

Fructose is the sugar in organic fruits that gives energy to cells and Glucose is the other one.
Explanation:
Glucose is the bad one for you body because it is unnatural sugar. Which means it sends energy to your body but the energy is used up very quickly. It is like cafience but it's baby.
The body works to maintain homeostasis in response to what conditions?
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.
