Relate similarities or differences between fish and scuba divers and they operate in water?

Answers

Answer 1

Fish can survive without scuba diving equipment, while scuba divers can not.

Fish were born and raised in the water, not like scuba divers.

Fish have gills that help them get air from the water, while humans do not.

Answer 2

Answer:

Breathing

Explanation:

Scuba divers need self-contained underwater breathing apparatus and they need equipment which helps them breathe comfortably while underwater, fish live there so they can breathe.

They both can swim and see other sea animals.

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.

Answers

Answer:

Give an example that illustrates lipids being waterproof.

Answers

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.

Explain the difference between physical and chemical properties. Provide an example of each.

Answers

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.

Is controlling homeostasis a conscious or unconscious process?

Answers

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.

Dependent: Less books read.

The Independent variable is ;  Time spent on social media  while The dependent variable is : Number of 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.

Your answer
This is a required question

Answers

Answer:

-10

Explanation:

add all temperatures together divide by 5 for your average

Answer:

-10°F

Explanation:

We want to find the average low temperature for the five days. To find an average, add up every value, then divide by the number of values.

The data given is:

-8°F, -13°F,  -4°F, -9°F, -16°F

1. Add the values

-8 + -13 + -4 + -9 + -16

-50

2. Divide by the number of values

Count how many numbers there are. The data was for 5 days, so there are 5 values.

-50/5

-10

The average low temperature for the 5 days was -10 degrees Fahrenheit.

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.

Answers

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.

Answers

Just the way you justify it and otherwise on the same point slot

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.

Syncretism has survived in some arts to this day. That the permeation of two or more arts (syncretism) is present in these modern ones as well. times, can be shown by several examples. theatrical art is impossible to imagine without a literary work, acting, music that accompanies certain situations on the stage and marks the atmosphere, but also fine arts that provide solutions for the appearance of the stage. In the film, the permeation of more art is even more emphasized: literature, music, acting, architecture that evokes the time and space of the action. literature is closely related not only to theater, film and television, but also to music, painting and sculpture. Poetry, for example, is always about music, and in two ways. Music is, first, in the very being of poetry. It was sung with a lyre instrument, it always strived for rhythmic and melodic organization of the verse. Sometimes the melodic sound aspects are so emphasized that the song gets its own melody and becomes very famous - it starts to be sung. The connection between literature and music is becoming even more serious at the level of world classics. Many of their works served as librettos for operas: Schiller's, Byron's, Pushkin's, Shakespeare's works. There is nothing less than a connection between literature and painting. and in this relation there is a two-way relationship. Literature inspires the creation of works of art, but also works of art inspire the birth of exceptional poetic works. Paul Gustave Dora took motifs from the Bible as the starting point and inspiration for his famous artistic achievements. He translated almost the entire Bible into the language of painting.
