So I have a question in science I need a few paragraphs done and I just need this explained. How dose the internal structure and the external features of organisms enhance their survival

Answers

Answer 1

The internal structure and external features of organisms have evolved to enhance their survival in various ways.

What does the internal structure of the organisms mean?

Internal structure refers to the internal organs and systems of an organism, such as the circulatory, respiratory, and nervous systems. These systems work together to maintain the organism's homeostasis, or internal balance, which is necessary for survival.

For example, the circulatory system transports oxygen and nutrients to cells, while the respiratory system removes carbon dioxide and other waste products.

What does the external structure of the organisms mean?

External features, such as body shape, coloration, and behavior, also play a role in an organism's survival. For example, camouflage can help an organism avoid predators, while bright colors can signal to potential mates. The shape of an organism can also be important for survival.

Overall, they work together to enhance the organism's chances of survival by allowing it to find food, avoid predators, and reproduce successfully.

A chemist analyzes two samples. One sample contains 14g of element x and 6.0 g of element y. The second sample contains 28 g of element x and samples are the same substance

Answers

Answer:

Explanation:

Here's the complete question:

A chemist analyzes two samples.One sample contains 14g of element x and 6.0g of element y.The second sample contains 28g of element x and 6.0g of element y. Does it appear that the two samples are the same substance?

The two samples that we are given in the question are different. They are not the same thing because we can deduce that their components ratio are different.

Sample One contains 14g of element x and 6.0g of element y. The ratio of element x to y is 14/6 = 7/3 = 7:3.

Sample Two contains 28g of element x and 6.0g of element y. The ratio of element x to y is 28/6 = 14/3 = 14:3.

Therefore, they have different ratio for their components and are therefore not thesame.

What is the average atomic mass of the isotopes shown in the table?

54.0
17.984
Isotope-B
32.0
18.985
Isotope-C
14.0
19.982

Answers

Answer:

18.58

Explanation:

From the question given above, the following data were:

Isotope A:

Abundance of A = 54%

Mass of A = 17.984 amu

Isotope B:

Abundance of B = 32%

Mass of B = 18.985 amu

Isotope C:

Abundance of C = 14%

Mass of C = 19.982 amu

Average atomic mass =?

AVERAGE = [(Mass of A × A%)/100)] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

AVERAGE = [(17.984 × 54%)/100] + [(18.985 × 32%)/100] + [(19.982 × 14%)/100]

= 9.71136 + 6.0752 + 2.79748

= 18.58

Therefore, the average atomic mass of the isotope is 18.58 amu

The pH of a solution is 8. Some hydrochloric acid is added to the solution. Suggest the pH of the solution after mixing. pH=.......??

Answers

Answer:

By adding acid to hydrogencarbonate you create a large concentration of CO2 in solution causing the solution to be highly supersaturated. This keeps the pH down as CO2 is in equilibrium with carbonic acid. During the day long mixing the excess CO2 strips off and as acid leaves the solution the pH increases.

Explanation:

Hope it helps

A solution with a pH of 8 will have its pH reduced with the addition of hydrochloric acid.

What is pH?

It is the degree of acidity or alkalinity of solutions.

pH ranges from 0 to 14 with 7 being a neutral pH. Any pH below 7 is acidic while above 7 is basic.

Thus, a pH of 8 is basic and the addition of hydrochloric acid will reduce it towards 7 or even below it.

Fire ants move in to a new environment with the lizards.what will most likely happen to the lizard population over the next several years

Answers

Answer:

Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting, and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new environmental challenges can override the historical influences that originally determined geographical trends in traits.

"Rapid environmental change, be it from changing climate or the introduction of invasive species, is putting a lot of pressure on native species," said Christopher Thawley, graduate student at Penn State at the time of the study and first author of the paper. "Usually when researchers look at how native species might respond to these kinds of threats, they might measure one characteristic of the animal and at one or a few sites. In this study, we looked at three separate characteristics of eastern fence lizards from thirteen sites spanning a thousand miles and found that these lizards are capable of adapting in a concerted way to meet the threat of invasive fire ants, and in a relatively short time frame."

Explanation:

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence ____are farther from the _____

Answers

Answer:

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.

Explanation:

The name of noble or inert gas is due to the lack of reactivity with other elements. This is due to its electronic configuration, because its outermost shell or valence shell is always complete, without the need to share, give or receive electrons forming bonds. That is, its outer layer is so stable that the element tends not to react with others except in very specific cases.

These exceptions generally involve the heavier noble gases, such as xenon or radon, capable of forming compounds with fluorine and oxygen. This is because the heavier noble gases have more electron shells than the lighter ones. This characteristic causes the outermost electrons to experience a "shielding" effect due to the action of the inner electrons, and they can then be ionized more easily, since the attraction they receive from the positive charges of the nucleus is weaker. That makes the ionization energy low enough to form stable compounds with more electronegative elements, such as fluorine and oxygen.

Heavier noble gases are able to form compounds with other elements under specific conditions because their valence electrons are farther from the nucleus.

cell
dust particle

Explain why you have them in this order. Be sure
to use a 5 complete thoughts.

Answers

Answer:

Atom, cell, dust particle, ant, ping pong ball

Explanation:

Firstly, atoms make up all matter, including each of the items on that list. The only things smaller than atoms are the parts of the atom itself, protons, neutrons and electrons. Because none of those are on that list, atoms have to be the smallest. Next smallest is the cell. Cells are made up of atoms, but they also in part make up dust. You can see a dust particle with the naked eye, but in order to see a cell you must use a microscope. Thus, cells are smaller than dust particles. Next is an ant. Obviously, an ant is bigger than a speck of dust, and is made up of cells and atoms. Lastly all you have is the ping pong ball, which is much larger than the rest of the items. Hope this helps!

All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Thus,  Atoms must be the tiniest object because none of those are included in that list. The cell is the next smallest. Atoms make up cells, but dust also makes up a portion of them.

A dust particle can be seen with the unaided eye, but a microscope is required to see a cell.

Cells are hence smaller than dust particles. An ant comes next. Of course, an ant is composed of cells and atoms and is larger than a particle of dust.

Thus, All matter, including each thing on the list, is made up of atoms. The protons, neutrons, and electrons that make up an atom are the only particles smaller than atoms.

Answers

Answer:

800.3 Kelvin

Explanation:

127°C = 400.15 Kelvin   (because 127 + 273.15)

Charles Law:

[tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex]   Thus, [tex]\frac{10.0 L}{400.15 K} = \frac{20.0 L}{T2}[/tex]

Then, work out the math algebraically.  

T2 = 20.0 / (10.0/400.15)

= 20.0 / 0.02499...

= 800.3 Kelvin

This is assuming the pressure remains constant.
