Can you drink the water from a cactus? Water is truly a precious resource in a desert, so, in addition to their intimidating spines, most cactus species further protect their spongy flesh with acids and potent alkaloids. These chemicals are usually too acrid for most humans to tolerate and are taxing on the kidneys if […]

Is your DNA the same in every cell? DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all […]

What are the examples of Endoskeletons? Some examples of endoskeleton are cartilage, bone, etc. The hard part present outside the body which protects the soft tissues and muscles is called the exoskeleton. It is developed from ectoderm and is mostly called a non-living structure. Some examples of the exoskeleton are hair, feather, scales, horns, etc. […]

Can we use natural resources forever? No, Padmaja we cannot use natural resources forever as they are present in limited amount in nature and take more than thousand year to recycle or regenerate again. Such natural resources comes into the category of non-renewable resources. Example- coal used for production of electricity and natural gas and […]

Why adsorption is a spontaneous process? Adsorption is a spontaneous process because there is a force of attraction existing between the adsorbate and adsorbent which releases heat energy. The delta H in this process is negative which means that the adsorption is a spontaneous process, and it is also an exothermic process. What causes adsorption? […]

Is dill weed a substitute for dill seed? Is dill weed an effective substitute for dill seed or vice versa? Because of the flavor differences, the seeds and leaves of the dill plant are not ideal replacements for each other; however, it is possible in a pinch. Keep in mind that you will need to […]

Concept Connections: The Four Basic Forces Force Approximate Relative Strengths Range Gravitational 10−38 ∞ Electromagnetic 10–2 ∞ Weak nuclear 10–13 <10–18 m Strong nuclear 1 <10–15 m What is the range of strong nuclear force? The nuclear force is powerfully attractive between nucleons at distances of about […]

What happened to the current in a series circuit? The same current flows through each part of a series circuit. The total resistance of a series circuit is equal to the sum of individual resistances. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor. If […]
