Answer: Part A: Exponential Growth

Part B: Interphase

Explanation: Part A: This is showing exponential growth because its increasing the quantity over time.

Part B: A cell spends most of its time in interphase because the interphase is the phase in the cell cycle that consists of three sub-stages which are (G1), (S), and (G2). It makes the cell grows and makes a copy of itself.

The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.

Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.

Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.

Hence, after many generations, puffins of species B and C will increase.

Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the gene that codes for hemoglobin, a protein responsible for carrying oxygen in red blood cells.

The mutation results in the production of an abnormal form of hemoglobin known as hemoglobin S (HbS). Sickle cell disease is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.

Effects at a Protein Level:

Hemoglobin normally has a rounded shape, allowing red blood cells to flow smoothly through blood vessels. However, in sickle cell disease, the abnormal hemoglobin S causes red blood cells to become stiff and take on a crescent or sickle shape under certain conditions, particularly when oxygen levels are low.

Effects at a Cellular Level:

The sickle-shaped red blood cells are prone to clump together, leading to the formation of blood clots. These clots can block blood vessels, causing a reduction in blood flow to various organs and tissues.

RBC’s make up about 84% of cells in the body, but they are only 4% of body weight. Whereas, 75% of total weight are fat cells and muscle cells. They’re both large cells but constitute only a minute fraction of the total number of cells.

How many cells is the human body made of?

The exact number of cells is still debatable. But to put it briefly, around 30-40 trillion. The long answer? Not yet determined.

What we do know, is that RBC’s (red blood cells) make up the majority of cells in our bodies. They make up only 4% of total mass, despite constituting 80% of all cells. The reason is that RBC’s measure 8 micrometers in diameter.  The size of fat cells, however is around 100 micrometers.

The total number of cells to this date is still not defined, but we have a slight idea of what could be.

Therefore, the reason for RBC’s having 84% of cells and 75% of fat cells is their mass. RBC’s are only 4% of total weight because their measure is only 8 micrometers. Whereas fat cells are around 100 micrometers in diameter.

The density of lions per each km² in the portion of the park that has been studied is 0.05125 lions/km², i.e., in this case this value equals to 41 lions/800 km².

The population density in a natural population can be obtained by dividing the number of individuals or organisms of a given species per unit of surface area in the ecosystem under study.

In this case, the studied area is 800 km² because it represents 20 percent (i.e. 20%) of an area that has 4000 km², while the number of lions in this area represents the population density and can be obtained as 41 lions/800 km2 >> 0.05125 lions per km².

Therefore, with this data, we can see that the population density is associated with the number of organisms of the same species in a given geographic area, which is generally referred to as the number of individuals per km².

The method by which ectothermic animals do not regulate their body temperature is: (A) by generating large amount of metabolic heat.

Ectothermic animals such as snakes as well as lizards do not utilize metabolic heat in order to maintain their body temperature. Ectothermic animals are primarily dependent on the external sources of heat. The body temperature of such animals changes according to the external temperature.

On the other hand, endothermic animals tend to maintain a uniform body temperature through the process of metabolic heat production, e.g. birds as well as mammals. The internal body temperature of endothermic animals is almost independent of the temperature of their surrounding habitat.

All cnidarians have two tissue layers. The outer layer is called the epidermis, whereas the inner layer is called the gastrodermis and lines the digestive cavity. Between these two layers is a non-living, jelly-like mesoglea

Cnidarias have an internal sac for digestion which is called the gastrovascular cavity. The gastrovascular cavity has only one opening, a mouth, through which the animal takes in food and releases waste. Tentacles radiate outward from the rim of the mouth.

The body wall of a cnidarian consists of three layers, an outer layer known as the epidermis, a middle layer called the mesoglea, and an inner layer referred to as the gastrodermis. The epidermis contains a collection of different types of cells. These include epitheliomuscular cells which contract and enable movement, interstitial cells that give rise to many other cell types such as egg and sperm, cnidocytes which are specialized cells unique to cnidarians which in some cnidarians contain stinging structures, mucus-secreting cells which glandular cells that secrete mucus, and receptor and nerve cells which collect and transmit sensory information.

The inner layer, the endoderm , has cells that produce digestive enzymes and break up food particles. The jellylike material between the two layers is called the mesoglea. All of these body layers surround a central cavity called the gastrovascular cavity, which extends into the hollow tentacles.

Note that the experiment you are performing is known as  "Solar water distillation" experiment.

The water in the cup is probably unclean because the dirt and water combination in the bowl filtered through the plastic wrap and into the cup via evaporation and condensation.

The plastic wrap represents the Earth's atmosphere, while the water in the cup represents purified water collected, or "distilled," by evaporation and condensation.

The water in the bowl would have evaporated and condensed on the inside of the plastic wrap, running down and into the cup. Evaporation and condensation are the two components of the water cycle at an action in this research.

The goal of the preceding experiment is to illustrate and comprehend the process of solar water distillation, which is a method of purifying water using the energy of the sun.

The experiment replicates the evaporation and condensation processes, in which the sun's heat causes the water in the bowl to evaporate and then condenses on the plastic wrap, pouring down into the cup.

The dirt and contaminants in the water are left in the bowl, resulting in clean water in the cup.

Pure water IV is not given to a dehydrating patient because our circulation already includes some salt, IVs also contain saline, a solution of water and salt that is almost isotonic with blood. Water flows from a high concentration to a low concentration, preventing the cells from exploding.

Patient would pass away. The cell would rupture owing to osmosis because of the disparity in salt content between the interior and exterior. In order to establish an isotonic state, the water would exit the cell and switch from the less concentrated inside to the more concentrated outside, killing the cell and ultimately the patient.
