Define, describe and give examples of Internal, External, and Behavioral adaptions.
Answers
Answer:
All organisms have adaptations that help them survive and thrive. Some adaptations are structural. Structural adaptations are physical features of an organism like the bill on a bird or the fur on a bear. Other adaptations are behavioral. Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations.
Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.
Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
birdFor example, imagine a bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species. The longer beak helps the bird catch more food. Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more. The bird passes the gene for a longer beak on to its offspring. They also live longer and have more offspring and the gene continues to be inherited generation after generation.
Eventually the longer beak can be found in all of the species. This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.
Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.
The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

The forces from below the surface that change the surface of the earth are
Erosion
Earthquakes
Volcanoes
Living things
Weathering
Faulting
Folding
Glaciers
Answers
Correct! The forces from below the surface that change the surface of the Earth include:
1. Erosion: The process of wearing away the Earth's surface by wind, water, ice, or other geological agents.2. Earthquakes: Sudden movements of the Earth's crust caused by the release of energy in the Earth's interior, resulting in shaking and sometimes surface displacement.3. Volcanoes: Openings in the Earth's crust through which molten rock, gases, and ash erupt onto the surface. Volcanic activity can lead to the formation of new landforms and alteration of existing ones.4. Weathering: The breakdown and alteration of rocks and minerals at or near the Earth's surface due to various physical, chemical, and biological processes.5. Faulting: The movement and displacement of rock layers along a fault line, typically caused by tectonic forces. This can result in the formation of new landforms or changes in the existing ones.6. Folding: The bending or warping of rock layers due to tectonic forces, resulting in the formation of folds and mountain ranges.7. Glaciers: Large masses of ice that slowly move over the Earth's surface, eroding the land and shaping the landscape through processes like plucking and abrasion.8. Living things: While not a direct force from below the surface, living organisms can play a role in shaping the Earth's surface through activities such as burrowing, root growth, and vegetation cover.These forces, both natural and influenced by living organisms, contribute to the continuous changes in the Earth's surface over time.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
Answers
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

Pull a balloon over the mouth of a bottle, and put the bottle in a saucepan of cold water. Slowly
heat the water over a stove. What happens to the balloon?
Take the bottle out of the water and allow it to cool. Now what happens to the balloon?
Explain, using the terms:
• molecule
• heat
• expansion
• contraction
Answers
Answer:
--- The hot air inside the bottle creates an expansion and when the hot water is applied a contraction occurs, thus causing the balloon to be sucked.
--- An internal pressure is produced, joining the heat begins to decrease. As a consequence, the air molecule causes the balloon to enter the bottle thanks to the effect of the external pressure.
Explanation:
I hope I have helped with something.
When the bottle is placed into the pan of hot water, the heat from the water causes the air inside the bottle to heat up. As the air in the bottle heats up, the molecules of the air begin to move faster and take up more space. The air from the bottle then moves into the balloon causing it to inflate.
What is heat?Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.
The hot air inside the bottle creates an expansion and when the hot water is applied a shrink occurs, thus causing the balloon to be contract.
Internal pressure is produced, joining the heat begins to decrease. As a consequence, the air molecule causes the balloon to enter the bottle thanks to the effect of the external pressure.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
Engineers test the safety of a new car by running a crash test, which shows whether the airbags inflate properly. When the car detects a crash, a small amount of sodium azide (NaN3) stored behind each airbag is heated. The sodium azide breaks down into sodium metal (Na) and nitrogen gas (N₂). The nitrogen gas inflates the airbags in less than one-tenth of a second! This design helps to keep people inside cars from getting seriously injured in a crash.
Complete the table to classify the substances in this chemical reaction.
Answers
Answer:
Under normal circumstances, this molecule is quite stable. If heated, though, it will fall apart. The chemical equation 2 NaN3 --> 2 Na + 3 N2 describes exactly how it falls apart. Notice that the second product of the above reaction is N2, also known as nitrogen gas. A handful (130 grams) of sodium azide will produce 67 liters of nitrogen gas--which is enough to inflate a normal air bag.
Explanation: Because of mathmaticsit works
Nitrogen gas (N2) and sodium metal (Na) are the products of the breakdown of sodium azide.
What is metal?Metal is defined as a solid with good electrical and thermal conductivity that is often hard, glossy, malleable, fusible, and ductile. The majority of metals are ductile and malleable, and they are often denser than other elements. The materials that have a propensity to donate electrons are metals. They have an electropositive makeup.
Airbags are inflated by nitrogen gas in less than a tenth of a second! Because to this design, occupants of cars are less likely to suffer severe injuries in collisions. Sodium azide, often known as NaN3, is the principal chemical involved in the air bag reaction. As a result of the heat produced, sodium azide breaks down into sodium metal and nitrogen gas, inflating the car's air bags.
Thus, nitrogen gas (N2) and sodium metal (Na) are the products of the breakdown of sodium azide.
