The attraction between the hydrogen atom on one water molecule and the oxygen
atom on another water molecule is called a(n)
Answer: Hydrogen bond or a covalent bond.
Explanation:
Can someone please give me An example of an ionic bond with a positive ion and negative ion
Answer:
NaCl
Explanation:
ionic bond is the bond results from the electro static force of attraction between oppositely charged ions in other words its the linkage formed by the transfer of one or more electron from one atom to another atom
Na gives it electron to chlroine so Na becomes positively charged and Cl becomes negatively charged and they attract each other to form ionic bond
Na is positive Cl is negative

Find the difference between testosterone and the steroid molecule.
Brainliest!
Answer:
It's true that anabolic steroids used by some bodybuilders and athletes contain testosterone or chemicals that act like testosterone. The difference is that doses used in testosterone replacement only achieve physiologic (natural) levels of hormone in the blood.

Explain the process of Mitosis and explain each phase.
Answer:
prophase-during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears
Metaphase-during which the chromosomes become attached to the spindle fibers.
Anaphase-which the chromosomes move away from one another to opposite poles of the spindle.
Telophase-in which the chromatids or chromosomes move to opposite ends of the cell and two Identical nuclei are formed.

carbon atoms has four valence electrons meaning that it can bond with two others
what is europhication
Answer:
Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases.
Plants that thrive in this type of climate are most likely adapted to which of these conditions
Answer:
Plants Adapting
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

Compare and contrast bodily reactions driven by two parts of the ANS: the sympathetic nervous system and the parasympathetic nervous system. Provide examples where each system would be highly active.
Difference
The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.
Examples of parasympathetic responses
An easy acronym to remember how and where the PSNS works is SLUDD. This stands for:
Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest.
Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.
Urination: The PSNS contracts the bladder, which squeezes it so urine can come out.
Digestion: The PSNS stimulates the release of saliva to promote digestion. It also enacts peristalsis, or the movement of the stomach and intestines, to digest food as well as release bile for the body to digest fats.
Defecation: The PSNS constricts the sphincters in the intestine and moves digested food material down the digestive tract so a person can have a bowel movement.
Examples of the Sympathetic Nervous System Response
The classic case of SNS response is a physical danger, especially with a potential predator, and the preparation of the body for either fight-or-flight. The overall system is designed to enhance voluntary muscle activity while shutting down all non-essential functions.
Arterioles and veins in most vascular beds constrict, reducing blood flow to the skin and digestive organs. Sphincters in the digestive organs also constrict, to control the flow of food from one organ to the next. However, coronary blood vessels, pulmonary circulation and parts of the respiratory tree respond with dilation, to enhance cardiac output. The heart beats with greater contractile force and at a higher frequency as well. Vasoconstriction in many parts of the body also increases blood pressure.
Similarity
Both are the part of ANS. Both originate from the spinal cord. Both have huge influence on physiological process of the body such as respiration, circulation, digestion, urination and reproduction.
The SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.
The autonomic nervous system (ANS) comprises the sympathetic system and parasympathetic system.
The sympathetic nervous stimulates 'fight or flight' responses, whereas the parasympathetic system activates 'rest and digest' responses.
The sympathetic nervous system is involved in body reactions such as the acceleration of the heart, constriction of the blood vessels, etc.
The sympathetic nervous system is involved in body reactions such as lowering the heart rate, lowering the flow of blood to skeletal muscles, etc.
Some examples that activate the parasympathetic system include:

StressOverstimulationIn conclusion, the SYMPATHETIC nervous system drives fight-or-flight responses, whereas the PARASYMPATHETIC nervous system drives “rest and digest” responses.

Krebs cycle
Electron transport chain
Fermentation
Glycolysis
Answer:
Krebs cycle
Explanation:
Electron transport chain
AD+ and NADH: NAD+ is an electron carrier that accepts a pair of high-energy electrons to become NADH. The NADH carries the high-energy electrons to the electron transport chain where they are used to build high-powered ATP molecules.
