Give an example that illustrates lipids being waterproof.
Answer:
Oils do not dissolve in water
Explanation:
Waxes are one of the forms of lipids, which are waterproof.
• Lipids are insoluble in water and are hydrophobic. They perform many essential activities within the cell.
• One of the forms of lipids is waxes, which envelopes the leaf surfaces of some plants, and the feathers of some aquatic birds.
• Due to the hydrophobic nature of waxes, they inhibit water from attaching to the surface. Thus, waxes are waterproof.
• The waxes are the long-chain fatty acid chains attached covalently with the long-chain alcohols.
Thus, waxes are the lipids that demonstrate the waterproof property of the lipids.

Phase changes occur when _____ is gained or lost from a substance.
Explain the difference between physical and chemical properties. Provide an example of each.
Answer: A physical property is when something can be observed or measured without being changed. A chemical property is when a substance undergoes a specific chemical change. Examples of physical property are color or density. Examples of chemical properties are flammability or heat of combustion.
I hope that this helps you !
The difference between physical and chemical properties of a substance depend on the fact that they affect the substance physically or affects its properties and identity.
Substances have characteristics that help in identify and thus classify them. Two of the broad classifications of these would include the chemical and physical properties of a particular substance.
Physical properties are those that can be identified without changing the identity of the substance.change in the physical appearance of matter such as color, density, hardness , are examples of physical properties.Properties that describe how a substance changes into a completely different substance are called chemical properties.Flammability and corrosion resistance are examples of chemical properties.Thus, the physical and chemical properties of a substance depend on the fact that they affect the substance physically or affects its properties and identity.

The more time people spend using social media, the less they read books.
Independent Variable:
Dependent Variable:
Answer:
Independent: Time on Social Media
Dependent: Less books read.
An independent variable in an experiment is a variable whose outcome is not affected by other variables present in the experiment. while
A dependent variable is a variable whose outcome is directly determined/affected by changes made by an independent variable in the experiment.
The number of books read is a dependent variable because it depends on the amount of time spent on social media ( independent variable ).
Hence we can conclude that the Independent variable in the experiment is the time spent on social media while the number of books read is a dependent variable.

What would happen if people stopped burning fossil fuels? *
Climate change would be reduced
Plants would struggle to grow
Ocean water would become more acidic
The atmosphere would heat up faster
Answer:
Even if we stopped burning fossil fuels, the Earth would continue warming up for another few decades because of all the heat we've already produced. Global temperatures would climb – finally stabilizing at a level much higher than we've ever known.

Answer:
the results of the investigation led to new scientific questions
Explanation:
The basis of every scientific question asked is an observation made. Scientific questions are questions that emanate from an observed problem and leads to the formation of a testable explanation (hypothesis). In this question, an investigation was made by a scientist and it was discovered that increased temperature decreases the number of offspring that an organism produces.
However, the scientist asks a new question about the impact of climate change on the species. This is because an observation has been made again, from the previously concluded investigation. Hence, after completing the investigation about the effect of temperature on the number of offsprings an organism can produce, an observation was made, ultimately leading to a new scientific question.

Answer:

Is controlling homeostasis a conscious or unconscious process?
Answer:
It is an unconcious process
Explanation:
Homeostasis is when the body is made sure to have a constant environment inside so that the body can work at it's optimum conditions .... constant temperature, constant pH etc ... you do sweat when you feel hot but you can't control it... your mind just tells it to... vadodilation and vasoconstriction for a constant temperature occurs for a constant temperature as well(when vessels dilate and constrict), your mind allows the vessels to do so without you thinking about it.
Homeostasis is an unconscious process.
Homeostasis can be defined as the ability of the organism to maintain the internal environment constant with respect to the changes occurring in the external environment. The steady state of the body can be achieved by the regulation of body temperature, pH, and metabolism. These changes are controlled by the hypothalamus gland in the human body which is without our conscious state of awareness. Some of these changes are control of heart rate, body temperature, and blood pressure.Hence, controlling homeostasis is an unconscious process.

How much momentum does a spaceship carrying rocks have? A. It has no momentum. B. It has less momentum than an empty spaceship traveling at the same velocity. C. It has more momentum than an empty spaceship traveling at the same velocity. D. It has the same amount of momentum as an empty spaceship traveling at the same velocity.
We can define the momentum of a moving object as the "amount of motion" and can be written as:
P = M*V
Where M is the mass and V is the velocity.
With this we will see that the correct option is B: "It has less momentum than an empty spaceship traveling at the same velocity."
Now we want to see which statement fits bets the momentum of the spaceship, let's analyze each option:
A) "It has no momentum."
If the spaceship moves, it has momentum, so this is false.
B) "It has less momentum than an empty spaceship traveling at the same velocity."
This is true, if the spaceship is empty, then it has less mass, thus the momentum would be smaller.
C) " It has more momentum than an empty spaceship traveling at the same velocity."
This is false, the same reasoning as above.
D) "It has the same amount of momentum as an empty spaceship traveling at the same velocity"
This is false, the same reasoning as above.
Finally, we can conclude that the correct option is B.

Name the main energystoring products of each phase of photosynthesis.
Explanation:
During the first stage of photosynthesis, called the light-dependent reaction, sunlight excites the electrons in the chlorophyll pigment. The organism uses this energy to create the energy carrier molecules ATP and NADPH, which are crucial for carbon fixing during the second stage.
The first two stages of photosynthesis depend directly on light because light energy is used to make ATP and NADPH. In the final stage of photosynthesis, ATP and NADPH are used to produce energy-storing sugar molecules from the carbon in carbon dioxide.
