1. Compact, complex animals have internal exchange surfaces that are extensively branched or folded, providing a large _____________.
2. In the _____________, nutrients are absorbed across the many fingerlike projections of the lining of the intestine.
3. In the _____________, oxygen and carbon dioxide are exchanged across the epithelial linings of sacs at the tips of tiny air tubes.
4. In the _____________, wastes are removed from the blood across the epithelial linings of excretory tubes.
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.
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

does the earth need the sun to rotate on its axis ??
Answer:
An observer in space will see that Earth requires 23 hours, 56 minutes, and 4 seconds to make one complete rotation on its axis. But because Earth moves around the Sun at the same time that it is rotating, the planet must turn just a little bit more to reach the same place relative to the Sun.
Answer:
Yes, but actually no.
Explanation:
Since gravity pulls inward from all directions equally, a clump, if big enough, will eventually become a round planet. Inertia then keeps that planet spinning on its axis unless something occurs to disturb it.
To simplify, due to gravity, things will keep spinning until something stops it from spinning (this applies to being in space, I think).

The length of days and nights at any location on Earth depends on the Earth's position with respect to the sun. Esmeraldas is at latitude 01°00'N. Which of these statements best describes the length of days and nights at Esmeraldas in the months of January and June? (1 point)
The days are longer in January and shorter in June.
The days are longer in June and shorter in January.
The lengths of days and nights are almost same in June and January.
The lengths of days are shorter and nights are longer in both June and January.
The answer is The days are shorter and nights are longer. In June, the sun is at its maximum inclination in the Northern hemisphere due to the earth's tilt with respect to the sun (Summer Solstice). Therefore, countries in the Southern hemisphere, such as Austrailia, will experience longer nights than days.

Alina notices that when she shines a desk lamp on a mirror, nothing happens.When she shines an infrared lamp on the mirror, the mirror starts to get warmer.Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?
Answer:
Because the infrared lamp gives off a type of light that the desk lamp does not, and the mirror can only take in the energy from the infrared light.
Explanation:
Answer:
Explanation:
Infrared is used for incubators when a chicken egg is about to hatch. It is the electrical frequency of electromagnetic radiation the provides heat.
Because heat is produced electrically it can be controlled with something resembling a dimmer switch (the kind of switch that dims lights in romantic restaurants). That means that the temperature can be set to the hen's body temperature.
Infrared is just below visible light.

Which of the terms below did you sort into the "aerobic" category?
Plz help,, explanation if possible because I don’t understand at all :,/
Answer:
I can't identify the phenotypes since I don't know what trait B represents, what trait C represents and what trait c represents.
But you can find the phenotypic ratio by finding the number of individuals with each phenotype. The yellow squares are individuals that all have the same phenotype as each other. And the blue squares have the same phenotype as each other, but a different phenotype from the yellow squares.
The ratio would be written as:
(number of yellow squres):(number of blue squares)

The atmosphere is full of nitrogen gas (N2). But plants cannot use nitrogen in this form. Summarize the roles of bacteria in making nitrogen available to plants and in returning nitrogen to the atmosphere.
Answer:
Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates.... Denitrifying bacteria converts nitrates back to nitrogen gas.

Speculate how mutations cause changes that can then be seen over many generations.
Answer:
Over thousands of generations, many mutations will be introduced into a population and some of these will increase to a detectable frequency as a result of selection or genetic drift. Both of these processes may take a long time to make a measurable increase in allele diversity. hope this helps :D
Mutations are errors produced during DNA replication. These errors can be perpetuated by successive cell divisions in daughter mutated cells.
A mutation is any alteration in the genetic material (DNA) of an organism. These mutations can occur as spontaneous genetic errors during DNA replication.
In somatic and germinal cells which suffered a mutation, each successive DNA replication cycle before mitosis/meiosis will produce new daughter cells carrying the mutation.
The consequence of this process is the perpetuation of the mutation in the cell lineage originated from a parental 'mutated' cell.
The DNA repair mechanisms work to avoid the perpetuation of genetic mutations.
Somatic mutations cannot be passed to the next generation (i.e., they are inherited by somatic cells that divide through mitosis), whereas germline mutations can eventually be inherited in the next generations through gametes.
In conclusion, mutations are errors produced during DNA replication. These errors can be perpetuated by successive cell divisions in daughter mutated cells. In germline cells, mutations can eventually be inherited by successive generations.

b. multiple copies of the dna sample are made
c. dna is destroyed so it has no value
Answer:
b. multiple copies of the dna sample are made
Explanation:
Polymerase chain reaction (PCR) is a method used to make millions to billions of copies i.e. complete copies or partial copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it. The new fragments of DNA that are synthesize during Polymerase chain reaction (PCR) also serve as templates to which the DNA polymerase enzyme can attach and start making DNA. The result of this attachment in a production of huge number of copies of the specific DNA segment in a short period of time.

Which sentence uses supporting evidence to form the best conclusion about a rattlesnake?
The sentence that uses the supporting evidence to form the best conclusion about a rattlesnake is as follows:
The rattlesnake's body temperature responded quickly to the environment, so it is an ectotherm.Thus, the correct option for this question is C.
What are Ectotherms?Ectotherms may be defined as the type of organisms that can not able to maintain their internal body temperature. They are also known as Poikilotherms. These types of organisms are absent on poles.
Due to a lack of internal maintenance of temperature, they can undergo hibernation and aestivation. Snakes and reptiles are ectothermic in nature. This significantly means that they directly obtain body heat from their environment.
Therefore, the rattlesnake's body temperature responded quickly to the environment, so it is an ectotherm is a sentence that uses the supporting evidence to form the best conclusion about a rattlesnake. Thus, the correct option for this question is C.
