What type of bond between water molecules pulls them into this tight ball?

Answers

Answer 1

Hydrogen bonds or h bonds are between water molecules

A water molecule contains an oxygen atom and two hydrogen atoms which are covalently bonded to the oxygen atom.Atoms in a covalently bonded molecule are always fighting for the shared electrons, the atoms attraction to the shared electrons is called the electronegativity. Therefore, the more electronegative an atom is the more it attracts the shared electrons.The force of attraction between a partially electronegative atom and another partially positive atom is the hydrogen bond. It is the hydrogen bond that pulls water molecules together which results into a cohesive force between the water molecules.

Describe the difference between ionic and molecular compounds.

Answers

Answer:

The main difference between Ionic and Molecular Compounds is that the electrons of atoms in ionic compounds are transferred between the elements because of the presence of a difference in electronegativity. However, in the case of molecular compounds, the electrons are only shared but not transferred.

Subject: Nitrogen cycle

Answers

Answer: Free nitrogen comes from bacteria breaking down the nitrogen compounds which causes it to be released in the air. Fix nitrogen is from soil, plants and animals consuming it which causes it to recycle, nitrogen is cycled through: plants, soil, animals, bacteria and water and the atmosphere. I hope this helped!

Explanation:

Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules. So, bacteria breaking down nitrogen compounds is an important step in the nitrogen cycle.

Peptic ulcers are sores in the lining of the stomach, they are cause by bacterial infection. The bacteria increases the acid in the stomach and ears away at the stomach linings, which makes sores. When this happens, what tissue does the acid remove?

Answers

Answer:

Peptic ulcer disease occurs when open sores, or ulcers, form in the stomach or first part of the small intestine. Many cases of peptic ulcer disease develop because a bacterial infection eats away the protective lining of the digestive system. People who frequently take pain relievers are more likely to develop ulcers.

Explanation:

Answer:

The acid in peptic ulcers can damage stomach tissue.

Explanation:

Ulcers form when the intestine or stomach's protective layer is broken down. When this happens, digestive juices - which contain hydrochloric acid an anzyme called pepsin - can damage the intestine or stomach tissue.

A student wants to find out if the amount of bleach has an effect on stain removal.

He plans to use two white shirts, stain each of them with mustard, and then wash each of them using bleach. He can change the size of the stain on the shirt and the amount of bleach he adds to the water.

Which test should the student set up?

Answers

Answer:

The second option.

Explanation:

We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.

The 2nd option uses different amounts of bleach to clean the same amount of stain.

If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.

It's not an effective way to see if the amount of bleach has an effect on stain removal.

Bleach is a Base, it’s a natural indicator which tells us whether the substance is a acid or a base.

Answers

answer B.

it’s melting

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting

Fireflies make their own light. The light they give off looks green. The spectrum of their light is shown. Describe how you would use a tool to see the spectrum of a firefly's light. Explain what the spectrum tells you about the light the firefly gives off. Include a comparison of the wavelengths of the light.

Answers

Answer:

Fireflies create light in a similar way to how a glowstick works. The light results from a chemical reaction, or chemiluminescence. When a light-producing chemical reaction occurs within a living organism, we call this property bioluminescence.

Explanation:

A firefly controls the beginning and end of the chemical reaction, and thus the start and stop of its light emission, by adding oxygen to the other chemicals needed to produce light. This happens in the insect's light organ. When oxygen is available, the light organ lights up, and when it is not available, the light goes out. Insects do not have lungs, but instead, transport oxygen from outside the body to the interior cells within through a complex series of successively smaller tubes known as tracheoles. For a long time, it was a mystery as to how some firefly species manage such a high flash rate, considering the relatively slow speed of the muscles that control oxygen transport.

The method that fireflies produce light is comparable to how glow sticks do. Chemiluminescence, a chemical process that produces light, is responsible.

What are the properties of firefly?

By providing oxygen to the other chemicals required to make light, a firefly can control the start and stop of the chemical process, and consequently, the start and stop of its light emission.

In the insect's light organ, this takes place. The light organ turns on when there is oxygen present, and turns off when there isn't any.

Since insects lack lungs, they use a complicated network of progressively smaller tubes called tracheoles to carry oxygen from the environment to their internal cells.

Therefore, Fireflies make their own light, this characteristic as bioluminescence when it takes place within a living thing.

Suppose you were asked to research information about a potentially dangerous synthetic food product. How would you evaluate the credibility of the sources you found?

Answers

Look at the studies cited in the source and the credentials of the scientists, if there are no studies cited it’s not a good source. Look at whether the ending of the link is .gov/.edu, any other ending is less credible. Check and see if the FDA has approved these food products or denied them. And finally look at the author and the authors credentials.

A good way to tell whether or not a website is reliable is the ending of the link (.com, .net, etc). Websites with .gov are more reliable because it is a government site. Websites with .com or .net can be reliable however it is always good to check the author of the website to make sure they know what they're talking about.

Write a paragraph (4-5 sentences) explaining how natural selection and selective breeding are related?

Answers

Natural selection and selective breeding are related because they both involve the process of selecting traits that are desirable. Natural selection is a process that occurs in nature where organisms with advantageous traits are more likely to survive and reproduce, passing on those traits to their offspring. Selective breeding, on the other hand, is a process where humans intentionally breed organisms with desirable traits in order to produce offspring with those traits. Both processes involve the selection of traits that are beneficial and can lead to the evolution of new species or the production of new varieties of crops or livestock.

Natural selection and selective breeding are related in that they both involve the deliberate selection of certain traits in a population. Natural selection is the process by which certain traits become more or less common over time due to their impact on an organism's ability to survive and reproduce. Selective breeding, on the other hand, involves the intentional breeding of organisms with desirable traits, such as high milk yield in cows or short stature in dogs. Both processes involve the selection of traits for their fitness or utility, but natural selection is driven by environmental pressures and survival, while breeding is driven by human desire or need.
