According to the research, the correct option is C. The respiratory and circulatory systems work together so that the inhaled gases are transported throughout the organism and then exhaled that allows blood to circulate bringing oxygen to cells.
How do the respiratory and circulatory systems work together?The circulatory system has the function of transporting oxygen from the respiratory system to all the cells of the body, accessing the nutrients they need to survive and develop and helps collect waste that is then expelled by exhaling air.
In this sense, the respiratory system is responsible for capturing oxygen through inspiration and eliminating carbon dioxide through exhalation.
Therefore, we can conclude that according to the research, the correct option is C. The respiratory and circulatory systems work together so that the inhaled gases are transported throughout the organism and then exhaled that allows blood to circulate bringing oxygen to cells.

If the mitochondria and chloroplasts in eukaryotic cells resulted from endosymbiosis between various prokaryotes, what features should these organelles have?.
According to the endosymbiotic theory, some of the organelles in eukaryotic cells of the present day were once prokaryotic microorganisms.
What is endosymbiotic theory?According to this hypothesis, the first eukaryotic cell was most likely a cell resembling an amoeba that obtained nutrients through phagocytosis and had a nucleus that developed when a portion of the cytoplasmic membrane pinched off around the chromosomes
As with prokaryotic cells, chloroplasts are the same size, divide via binary fission, and have Fts proteins at their division plane.
The mitochondria of some protists have Fts homologs at their division plane and are the same size as prokaryotic cells. They divide by binary fission.The DNA in mitochondria and chloroplasts is circular rather than linear.The ribosomes found in mitochondria and chloroplasts have 30S and 50S subunits rather than 40S and 60S.Therefore, According to the endosymbiotic theory, some of the organelles in eukaryotic cells of the present day were once prokaryotic microorganisms.

You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. In what location of the cell would you begin this observation?.
You are doing a study on the enzymatic effects of lysosomes and want to follow the whole process from the formation of the enzymes to their use in the lysosome. The endoplasmic reticulum (ER) is the place where this observation will begin.
As we want to begin with the process of formation of enzymes, hence Endoplasmic reticulum (ER) will be the place to begin. This is because the endoplasmic reticulum (ER) is the place in the body that plays a central role in the synthesis of proteins.
The ribosomes are attached to the rough endoplasmic reticulum which is responsible for the translation process of mRNA that results in protein formation. The endoplasmic reticulum plays a central role in the formation of proteins.

When scientists use logic to determine the age of one fossil compared to another, they use this
type of dating?
Relative
O Carbon
O Absolute
Answer: Carbon Dating though measuring Carbon-14 levels
Explanation:
Scientist measure the age of a fossil determined on the Carbon-14 level compared to the Carbon-12 level. This method works because:
All organisms after their death stop replenishing the amount of carbon in their body. That means that they will have an equal amount of carbon-12 and carbon-14 until they die. Unlike carbon-12, carbon-14 is unstable and overtime will go through beta decay. Overtime, a carbon-14 neutron will become a proton and release an electron, transforming into nitrogen-14.This leads to a drop in carbon-14 level, and because of this, geologist compare the level of carbon-14 to carbon-12 to determine how long it has taken to reach such stage.Ten grams of sugar is placed in a beaker with 100ml of water.

Answer:
A
Explanation:
Took the test
At 0° Kelvin or absolute zero, all particle motion stops. Thus, option A is correct.
What is absolute zero?
The lowest limit of the thermodynamic scale that measures temperature is known as absolute zero. It is also a condition in which entropy and enthalpy of a ideal gas which is cooled reached to its maximum value and the reading is taken as zero kelvin.
Absolute zero is also the lowest energy temperature in the thermodynamics and there is no cooling of an object on temperature that is exactly absolute zero.
Thermal energy is also hold a conservation of energy it means energy can't be created nor be destroyed but in real world when energy is transformed from one system to another system the efficiency is always decreases. So we can say that loss of energy is takes place but it's loss to friction or resistance in term of mechanics.

After swallowing, in what order does food pass through the regions of the gi tract?.
Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food.
What is Stomach?Humans and many other animals, including numerous invertebrates, have a muscular, hollow organ called the stomach in their gastrointestinal tracts. The stomach is a crucial organ in the digestive system and has a dilated configuration. Following chewing, the stomach participates in the gastric phase of digestion. Using enzymes and hydrochloric acid, it performs a chemical breakdown.
The stomach is situated between the oesophagus and the small intestine in humans and many other animals. To aid in food digestion, the stomach secretes gastric acid and digestive enzymes. The pyloric sphincter regulates how food that hasn't fully broken down (called chyme) moves from the stomach to the duodenum, where peristalsis takes over to move it through the rest of the intestines.

It is True, the unit of radiation absorbed energy or dose, is used for biology material only.
What is Absorbed Dose?The average dosage that is absorbed over an organ or tissue is commonly used to determine absorbed dose. This is obviously oversimplifying the true scenario. When an organ or person is exposed to radiation, the dosage is typically not homogenous throughout the volume of the organ.
The idea that the harm will occur whether the organ is exposed to radiation consistently or unevenly is a simplification that is adopted. This is certainly not true in severe situations, but if the nonuniformity is around 50% or less throughout the organ or person of interest, the mean organ dosage definitely may be employed successfully.
