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.

Place the following steps of endomembrane system function in the correct order.
1. Golgi apparatus receives transport vesicles from the RER.

3. Proteins are packaged into transport vesicles.
4. Modified proteins may be secreted from the cell by exocytosis.
5. Proteins are modified by the Golgi apparatus.
A. 2, 4, 3, 1, 5
B. 3, 2, 1, 4, 5
C. 1, 2, 3, 5, 4
D. 2, 3, 1, 5, 4
Answer:
D
Explanation:
The correct option here would be D.
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
Ribosomes on the RER synthesize proteins.Proteins are packaged into transport vesicles.Golgi apparatus receives transport vesicles from the RER.Proteins are modified by the Golgi apparatus.Modified proteins may be secreted from the cell by exocytosis.Protein synthesis involves transcription and translation. Once the protein is synthesized, it suffers a few modifications in the RER and the Golgi complex, before leaving to its final destiny. The correct option is D. ⇒ 2, 3, 1, 5, 4
Protein synthesis and modificationTranscription ⇒ mRNA syntheisThe first step before protein synthesis begins is to synthesize messenger RNA, mRNA.
This is the coping process of the DNA section for the desired protein, and it happens in the nucleus.
Translation: Cytoplasm stageTranslation takes place when the formed mRNA moves to the cytoplasm through the nucleus membrane pores, and meets a ribosome.
Ribosomes are organelles composed by the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.
While the ribosome reads mRNA strain from its 5´ extreme to 3´, tRNA adds the correct amino acids to build the polypeptide.
Endoplasmic Reticulum StageSome proteins are destined for membrane or exportation. Their synthesis starts in the cytoplasm but finishes in the Rough endoplasmic reticulum.
When the ribosome and the growing molecule reach the RER, the synthesizing protein keeps enlarging forward the reticulum lumen.
When the new polypeptide synthesis is complete, it is released into the reticulum lumen.
The endoplasmic reticulum is in charge of protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction and initiates the glycosylation process.
The new proteins get packaged into vesicles that carry them to the Golgi complex.
Golgi complex stageOnce the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex.
In the Golgi complex, proteins suffer their final association with carbohydrates and lipids to originate glycoproteins and glycolipids.
Destiny stageGlycoproteins and glycolipids are packaged again into new vesicles that drive them to their final destiny.
Proteins destined for exportation are packaged and sent from the Golgi complex to the cell membrane into vesicles.
When the secretory vesicle reaches the target, its membrane fuses with the cell membrane, releasing its content to the extracellular space. This secreting process is known as exocytosis.
According to this resume about protein synthesis, we can say that the correct order is option D. ⇒ 2, 3, 1, 5, 4
2. Ribosomes on the RER synthesize proteins.
3. Proteins are packaged into transport vesicles.
1. Golgi apparatus receives transport vesicles from the RER.
5. Proteins are modified by the Golgi apparatus.
4. Modified proteins may be secreted from the cell by exocytosis.

(Temperature is the average speed of the particles of the gas)
F. What happens to the speed of the particles when a gas is cooled?
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.

Fructose is the sugar in organic fruits that gives energy to cells and Glucose is the other one.

What happens when self-determination mechanisms break down?
Answer:
When self-determination mechanisms break down it mistakes self-tissue as foreign agents and pathogens. This results is Auto-Immune disease.
HOPE THIS HELPS!
When the self-determination mechanisms break down, the body misinterprets its own tissues as foreign antigens, which activates the autoimmune mechanisms to destroy the body's own cells, mistaking them for foreign factors, this happens mainly in mantle autoimmune diseases.
Autoimmune diseases are a group of diseases in which tissue damage is caused by a humoral or cell-mediated immune response to a person's own antigens.
What are antigens ?In immunology, an antigen (Ag) is a molecule or molecular structure or any foreign particle or pollen grain that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body can trigger an immune response. The term antigen originally referred to a substance that is a generator of antibodies. Antigens can be proteins, peptides (chains of amino acids), polysaccharides (chains of monosaccharides/simple sugars), lipids or nucleic acids. Antigens are recognized by antigen receptors, including antibodies and T-cell receptors.

Birth rate is the number of individuals born in a population in a particular time period. Birth rate adds more individuals to a population.
Death rate is the number of individuals die in a population in a particular time period. Death rate decreases the population number.
Immigration is the number of individuals which enter a population.
Emigration is the number of individuals which migrate out of a population.
