Paramecium is part of the protist group, it is found in almost every water body.
They are unicellular organism, Their movement is thanks to the hair-like strutures called cilia. Thats the locomotive organs. they move at the same time against the water so they can create cinetic energy.
As other microorfanism, the Paramecium moves to sweep the prey, with the oral groove, and into the cell. It is feed by plants, like algae, small bits of animals and vegetables, also some bavteria and protozoa

Which of the following factors is most likely to remain stable throughout adolescence?
a. temperament
b. abstract thinking skills
c. identity
d. risk taking behaviors
Temperament is the factors most likely to remain stable throughout adolescence.
What is Adolescence?
Adolescence is a stage of physical and psychological development that normally occurs between puberty and maturity. Adolescence is commonly connected with adolescence, however its physical, psychological, or cultural manifestations might begin sooner and end later. Puberty today usually starts at preadolescence, especially in females. Physical and cognitive development can continue past the adolescent years. Age is simply an approximate indicator of adolescence, and researchers have yet to agree on a specific description.
Temperament is an important part of children's psychological functioning and is thought to remain rather stable throughout childhood. However, little research has been conducted to examine temperament stability from early childhood to early adolescence.
So, A is the correct answer.

If the spinach leaf disks were boiled before being tested, what results would you expect, and why?
If the spinach leaf disks were boiled before being tested, all the leaf disks would sink which is as a result of the lack of space for gases.
What is Sink?This is referred to as the condition in which a substance goes below the surface of a material and is usually in a submerged position due to some factors.
When the spinach leaf disks is boiled, gases form which are usually in the form of vapor and therefore gives rise to it sinking as a result of there not being space for them and the photosynthetic ability is greatly reduced which is therefore why it was chosen as the correct choice.

Half-life (symbol: t1/2), which is the amount of time needed for half of the initial substance to alter or degrade, is a helpful notion.
What is half life?There is value in being able to express the rate at which a process occurs since the decay process takes time. Measurements of a nuclide's change in mass and the time it takes for that change to occur can be used to compute half-lives.
The only thing we do know is that half of the initial nuclei will dissolve over the substance's half-life. Although variables like temperature, concentration, and others have the ability to speed up or slow down chemical reactions.

The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across.
In a chemical reaction, atoms cannot be formed or destroyed since they are indivisible units. The mass and chemical characteristics of each atom of a specific element are the same. Different elements' atoms have varying weight and chemical characteristics. Compounds are created when atoms combine in ratios of small whole numbers.

Decomposition is a physical and chemical process by which dead organic matter is broken down. Why is decomposition important to life processes?
The process of decomposition that breaks down dead organic matter is important to life because it maintains the cycle of transfer of nutrients from one component of life to another.
Decomposition is the process of break down of complex organic material of the dead and decaying organisms into simpler organic matter. The examples of the species involved in decomposition are: Psychrophiles, Protozoans, Molds, etc.
Nutrients are the compounds that are essential for the growth and nourishment of the body. They get transferred from one living organism to another in the form of food. Hence the extraction of nutrients from the dead organism is essential so that the nutrients can be used by other organisms. That is why decomposition process is essential.

12. Which of the following would be a reason why a cell would divide when itreaches its growth limit?A. Smaller cells have difficulty obtaining nutrients and removing wastes.B. Smaller cells can more easily transport nutrients and remove wastes.C. Smaller cells have difficulty communicating instructions for cellularfunctions
We have to consider that when a cell is smaller with respect to another higher cell, there is better efficiency in the metabolic processes they carry out since a smaller cytoplasm and a smaller cell membrane surface can represent a faster movement of molecules inside the cell, from the inside to the outside, and vice versa. Having this clear, we can say that a reason why a cell would divide when it reaches its growth limit is that smaller cells can more easily transport nutrients and remove wastes, as stated in the B answer option. This is because small cells have a major surface volume ratio than more big cells, which allows them to, in a more reduced space, move molecules more with greater ability.
An example of this can be seen in the following picture, which represents three different cells of different sizes, having the smaller cells at the left of the image, a higher surface volume ratio (sa:v), and at the right part of the image, a bigger cell with a lower surface volume ratio.
SA= surface area
V= volume
SA:V= surface area volume ratio, or surface volume ratio.

Exocytosis: secretes large molecules out of the cell; requires fusion of vesicles with the plasma membrane; increases the surface area of the plasma membrane. (G, B, E)
Endocytosis: forms vesicles from inward folding of the plasma membrane; decreases the surface area of the plasma membrane. (C, A)
Both Exocytosis and Endocytosis: requires cellular energy; transported substances never physically cross the plasma membrane. (F, D)

A coffee cup calorimeter contains water at an initial temperature of 20.0 °C and

of 75.0 J/°C. A 28 g piece of an unknown metal is removed from a pot of boiling
water with a temperature of 100.0 °C and placed into the calorimeter. The
contents of the calorimeter come to an average temperature of 27.0 °C. What is
the specific heat capacity of the metal?
A) 0.26 J/g °C
B) 3.89 J/g °C
C) 4.18 J/g °C
D) 7.19 J/g °C
E) 75.0 J/g °C
The specific heat capacity of the metal is obtained to be 2.68 J/g ºC.
What is the heat capacity of metal?The heat capacity of a metal is the amount of heat which is required to raise the temperature of a material by 1ºC. The heat that is lost by the surface of metal is equal to the heat that is gained by the calorimeter here. This transfer of heat is based on the first law of thermodynamics which states that energy can neither be created nor be destroyed it can only be transferred.
Heat lost by metal = (28 g)(C)(100 - 27) = (28g)(C)(73º) = 2044C
Water would gain a heat of:
75 J/ºC x 73ºC = 5475 J
We would now have; 2044(C) = 5475
C = specific heat of the metal = 2.68 J/g/ºC
