5. The _____________ transports materials between the exchange surfaces of other organ systems and body cells.
6. Body cells are bathed in _______________, and exchange between body cells and the blood takes place through this fluid.

Answers

Answer:

1.) Surface area

2.) Digestive system

3.) Respiratory system

4.) Urinary system

5.) Circulatory system

6.) Interstitial fluid

Explanation:

In higher complex animals, such as the vertebrates, the internal exchange surfaces are modified in such a way to facilitate the transfer of materials from cell to cell in the body. As animal size increases, diffusion distances increase and the ratio of surface area to volume drops. Larger organisms have had to evolve specialized systems that are made up of structures that provides a large surface area for internal exchange of materials. Examples of these systems include:

--> DIGESTIVE SYSTEM: The fingerlike projections of the lining of the intestine provide a large surface area for the absorption of nutrients.

--> RESPIRATORY SYSTEM: This ends with a sac called the alveolar sac. The anatomical arrangement of capillaries and alveoli produces a very large surface area that is available for gas exchange.

--> URINARY SYSTEM: wastes are easily removed from the blood across the epithelial linings of excretory tubes.

--> CIRCULATORY SYSTEM: transports materials between the exchange surfaces of other organ systems and body cells. An example is seen in the relationship between the alveoli and the capillaries surrounding it.

For any exchange of materials to occur between cells the fluid known as the INTERSTITIAL FLUID which fills the intercellular spaces allows dissolved materials to be exchanged between body cells and the blood

HELP! A 20-kg bag of rice dropped from an airplane. What is the gravitational force on the bag? Acceleration due to gravity is 9.8 m/s/s.)
10.02 N

19.6 N

20.8 N

196 N

Answers

Answer:

20.8

Explanation:

I took it and it was right

196N is the gravitational force on the bag. So, the correct option is D.

What is gravitational force?

Any two items in the universe can be attracted to one another by the gravitational force. All mass-containing objects are drawn towards one another by this attraction, which also keeps the moon in its orbit around the Earth and the planets in their orbits around the sun.

The mass of the two objects and their separation determine the gravitational force's strength. The force of gravity between two objects is directly proportional to their masses and inversely correlated to the square of their distance, according to Newton's law of universal gravitation.

The gravitational force on the bag can be calculated using the formula:

force = mass x acceleration due to gravity

Plugging in the given values, we get:

Force = 20 kg x 9.8 m/s/s

Force = 196 N

Therefore, the correct option is D.

How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light.

The can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.

Answers

Answer:

Over time, a series of random occurrences can cause an allele to become more or less common in a population. This is called Genetic drift.

When a population is severely reduced by an environmental disaster such as a fire, the result is a Bottleneck effect due to the reduced genetic diversity of the survivors.

The Founder effect can occur if a small group of organisms migrates to a new location and becomes isolated from the rest of the population.

Explanation:

Genetic drift is an evolutive force. It is the random change that occurs in the allelic frequency of a population through generations. Its effects are harder in a small-sized population, meaning that the magnitude of this change is inversely related to the size of the original population.  

Genetic drift results in some alleles loss -including the beneficial ones-, while some other alleles get fixated. Low-frequency alleles are the most likely to be lost. The changes produced by genetic drift accumulate in time and results in a loss of genetic variability within a population.  

Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure -bottleneck effect- or because of a population split -founder effect-. The bottleneck effect most likely affects smaller populations.  

The bottleneck effect -a case of genetic drift-, mostly affects smaller populations after the occurrence of a natural disaster or some human action -such as extensive hunting, for instance-. These events might act as a pressure that reduces significantly the number of individuals in a population. In these situations, some alleles are lost, and the survivors have a different genetic charge than the one of the original population. There might be a reduced genetic variability, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation.  

Founder effect refers to the origin of a new population from only a few individuals that are coming from a bigger-sized population. These founder individuals, which are carrying some of the genes of the original population, settle down in a new area and reproduce.  The new and small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be lost by complete. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced, and there exists the possibility of developing a peculiar allelic composition. When the number of individuals that originated the new population is low, the founder effect will be very extreme because the genetic drift effects are inversely proportional to the original number of individuals.

Three ways to be exposed to toxic substances:

1. Inhalation - Inhalation is when we are breathing something into our lungs. For example, a firefighter may ingest toxic gasses and chemicals when entering a burning house.

2. Ingestion - Ingestion is when we are taking something by mouth. If someone eats a piece of cheese that is expired, they will most likely get food poisoning.

3. Skin contact - Skin contact is when a substance is in direct contact with our skin. For example, if someone spills an acidic substance on their arm during science class, this is considered a toxin and they may get a painful chemical burn.
