Which type of bond holds atoms together in a water molecule?
A. nuclear bond
B. ionic bond
C. organic bond
D. covalent bond
D. covalent bond that your answer
Hydrogen and oxygen are non-metallic. They were bonded together using covalent bonds. As a result of sharing electrons, oxygen, and hydrogen maintain their entire outer shells rather than losing them. Thus, option D is correct.
What is a covalent bond?When two atoms exchange one or more pairs of electrons, a covalent connection is created. These electrons are simultaneously pulled to the two atomic nuclei.
A covalent bond is created when the difference between the electronegativities of two atoms is too small for an electron transfer to occur and produce ions. Covalent bonds are frequently formed between nonmetals.
For instance, each hydrogen (H) and oxygen (O) atom in water (H2O) shares a pair of electrons to comprise the molecule of two single-bonded hydrogen atoms and one single-bonded oxygen atom.
Therefore, covalent bond of bond holds atoms together in a water molecule.

The lock alpha channel command makes your selection __________.
The lock alpha channel command makes your selection unchangeable in terms of transparency. After locking, you can't adjust the transparency of that part of the image.
Explanation:The lock alpha channel command in programs like Photoshop makes your selection immutable in terms of transparency. That is, once you lock the alpha channel, the transparency of what you've selected cannot be altered. For example, if you have selected a portion of an image and subsequently locked the alpha channel, no matter what alterations you make thereafter, the transparency of that selected portion would remain the same as it was at the time of locking this alpha channel.

what is one sign that indicates a physical change?
a) matter changes, but no new substance is formed
b) a substance changes color when exposed to air.
c) something catches fire and turns back
d) temperature drops as two liquids are mixed together
Final answer:
Option a is the correct answer. One sign that indicates a physical change is that matter changes, but no new substance is formed. Another example is when a solid melts and becomes a liquid, it is still the same substance, just in a different form. Temperature drops as two liquids are mixed together is also an example of a physical change.
Explanation:
One sign that indicates a physical change is that matter changes, but no new substance is formed.
This means that even though the form of matter may change,but its identity remains the same. For example, when water evaporates and changes from a liquid to a gas, it is still water. Another example we can give is when a solid melts and becomes a liquid, it is still the same substance, just in a different form.
Temperature drops as two liquids are mixed together is actually an example of a physical change. While the temperature may decrease, no new substance is formed.

Jet lag occurs when a person moves rapidly from one time zone to another, causing conflict between the body's biological rhythm and the new cycle of light and dark. some scientists suspect that jet lag may result from disruption of the daily cycle of secretion of the hormone known as _____.
The jetlag may result from disruption of the daily cycle of secretion of the hormone known as melatonin. This is a hormone in which is produced or made by the pineal gland, they are the one responsible of having to control a person’s wake cycles and their sleep in which in jetlag, can disrupt this hormone causing a disruption with the body clock of the individual.

When caring for a patient with leg ulcers, the positioning of the legs depends on whether the patient's ulcer is arterial or venous in origin. how should the nurse position a patient who has leg ulcers that are venous in origin?
The nurse should position the patient with leg ulcers that are venous in origin with the legs elevated above the level of the heart.
Venous ulcers are caused by improper functioning of the venous valves, which leads to increased venous pressure, particularly when the legs are dependent. This increased pressure can cause fluid to leak out of the capillaries and into the surrounding tissues, leading to edema and exacerbating the ulceration.
To alleviate the symptoms and promote healing, it is recommended to elevate the legs above the level of the heart. This positioning uses gravity to assist in reducing venous pressure and edema in the lower extremities. By elevating the legs, the hydrostatic pressure in the veins is decreased, which helps to minimize the leakage of fluid into the interstitial space and reduces the workload on the venous system. This can lead to a decrease in swelling and pain, and it can also improve the circulation of blood and oxygen to the ulcerated area, which is conducive to the healing process.
In contrast, arterial ulcers, which are due to poor arterial circulation, would not benefit from leg elevation. In fact, elevating the legs in cases of arterial ulcers could worsen the condition by further reducing blood flow to the affected area. Therefore, it is crucial to differentiate between venous and arterial ulcers when determining the appropriate nursing care and positioning of the patient."
When cars age or are poorly maintained they tend to leak oil onto roadways and parking lot they saw oil is washed into the nearest Waterway with the next rainfall what type of water pollution does this cause

The correct option is A i.e. Toxic.
Oil leaks from cars contribute to non-point source pollution, which contaminates waterways with toxic substances. This can harm aquatic ecosystems and degrade water quality.
When cars age or are poorly maintained, they can leak oil onto roadways and parking lots. This oil is washed into the nearest waterway with rainfall, causing a type of pollution known as non-point source pollution. Non-point source pollution occurs when contaminants such as oil, gasoline, and other automotive fluids are washed off surfaces by rainwater and flow into water bodies like rivers, lakes, and oceans.This type of pollution is harmful because it can introduce toxic substances into aquatic ecosystems, affecting the health of both the environment and human populations. Key contaminants from road runoff include not only oil and gas but also metals and organic waste, all of which can degrade water quality and impact water treatment facilities. To address this issue, it is important to properly dispose of motor oil and other chemicals, fix leaking vehicles promptly, and use fewer chemicals in other land-based activities. By taking these steps, we can reduce the contamination of our water supplies and protect the environment.The complete question is:

Why is it important to know whether or not bacterial cells possess capsules flagella and endospores?
Final answer:
Knowing the presence of capsules, flagella, and endospores in bacterial cells is important for understanding bacterial survival and interactions with the environment, as well as developing strategies to control bacterial infections.
Explanation:
Knowing whether or not bacterial cells possess capsules, flagella, and endospores is important because these structures have various functions and play key roles in bacterial survival and interactions with the environment.
The capsule is a protective layer that enables bacteria to attach to surfaces and evade the immune system. Flagella allow bacteria to move and navigate their surroundings. Endospores are dormant structures formed by some bacteria to survive harsh conditions such as extreme temperatures and lack of nutrients.
Understanding these structures helps in identifying and classifying bacteria, as well as developing strategies to control bacterial infections.
