A student finds that the mass of 25mL of an unknown liquid is 20.5g. What is the density of this substance?

Answers

Answer:

Density, [tex]d=0.82\ g/cm^3[/tex]

Explanation:

It is given that,

Mass of unknown liquid is 20.5 kg

Volume, V = 25 mL

We know that, 1 mL = 1 cm³

25 mL = 25 cm³

The density of the substance is equal to its mass per unit volume. So,

[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3[/tex]

So, the density of this substance is [tex]0.82\ g/cm^3[/tex].

Why did the author think e-skin could make better hearing aids? In your answer, explain how the ears connect to the nervous system

Answers

Answer:

The author thought this because e-skin might hold promise for use in soft, wearable hearing aids. Unlike conventional aids, soft devices are more comfortable because they mold to human skin. When the ear receives sound vibrations, there are hair cells in the cochlea that vibrate and translate the sounds into electrical signals. These electrical signals are transmitted to the auditory nerve, which transmits the information to the brain.

Answer:

Sound is one of the five major senses. The nervous system carries sound signals from sensory receptors to the brain. E-skin has many sensory receptors that can carry signals toward the brain, enabling us to react to sounds. Because e-skin is soft, scientists can use it to make effective hearing aids that are quite comfortable to wear.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists

A. could not confirm the usefulness of sonar

B. could destroy the hypothesis of continental drift

C. could not provide a mechanism for moving continents

D. could explain how the seafloor was being destroyed

Answers

Answer:

C. could not provide a mechanism for moving continents

Explanation:

Without the discovery of magnetic reversals recorded on the ocean floor, scientists  could not provide a mechanism for moving continents.

Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents  and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.

Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.

The study of a living being is called biology.

The correct answer is C.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents because magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rhythm of the magnetic reversal rate.  Therefore the discovery of magnetic reversals is important to identify the mechanism for moving continents.

Hence, the correct answer is C that it could not provide a mechanism for moving continents.

Answer:

distal tubule, the concentration of ADH

Explanation:

Nephron is the functional unit of kidney. Nephron undergo reabsorption and secretion along different part.

The permeability of distal tubule to water in the second coiled tubule of the nephron is controlled by the concentration of ADH. The concentartion of ADH controls the degree of dilution or urine concentration. High ADH level makes , tubules permeable to water while the absence of ADH makes them impermeable to water.

True or False: Within the body, all atoms combine to form molecules. If false, why?

Answers

Two or more atoms combine to form a molecule, like how the water molecules, proteins, and sugars are found in living things.

Hope this helps! (づ ̄3 ̄)づ╭❤~

The statement i.e. ''Within the body, all atoms combine to form molecules'' is true.

Atoms combine together to form molecules because atom is unstable substance which can't stay in single form due to its reactive nature but become stable when they form molecules due to filling of outermost shell and attain the electronic configuration of noble gases so we can say that atoms formed molecules in order to attain stability and can not remain individually.

Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin?
a. hypoxemic hypoxia
b. ischemic (stagnant) hypoxia
c. anemic hypoxiad. histotoxic hypoxia

Answers

Answer:

c. Anemic hypoxia

Explanation:

Hypoxia is a health condition in which the body or a region of the body is not adequately supply with oxygen  at the tissue level. Types of hypoxia include:

Hypoxemic hypoxia is a condition in which their is low level of oxygen in blood in the arteries due to the inability of the lungs to properly oxygenate blood.

Ischemic (stagnant) hypoxia is a type of hypoxia that occurs due to a decrease in blood flow preventing adequate blood supply to tissues.

Anemic hypoxia occurs when the ability of the blood to carry oxyegen is reduced due fewer red blood cells or red blood cells that contain little or abnormal hemoglobin molecules hemoglobin molecules.

Histotoxic hypoxia is hypoxia in which the cells are unable to use oxygen from the bloodstream, even though there is normal delivery of oxygen to such cells and tissues. This is due to the poisoning of the cells or tissues causing a disruption in their respiratory mechanism, for example in Cyanide poisoning.

Therefore, the correct answer is anemic hypoxia.

What are two ways the excretory system helps the body maintain homeostasis?

Answers

Answer:

1.Osmoregulation

2.Thermoregulation

Explanation:

1.Osmoregulation is the maintenance of constant amount of water in the body of an organism.The kidney is responsible for this phenomenon as in it has a nephron in which at a particular part of the nephron,i.e the conducting tube which sites a hormone called the anti diuretic hormone which makes the walls of the conducting tube permeable to allow the movement of water from the urea back into the body before it is transferred into the bladder for to be released into the external environment.

2.Thermoregulation involves the maintenance of heat in the body of an organism.The skin is responsible for this process.It has hairs which lie on the surface of the skin to loose heat to the external environment during the hot days and also stands on the surface of the skin which trap a film of air on the skin surface to prevent heat loss in the cold days.

a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain

Answers

Answer:

a. Hypertonic solution

b. Hypotonic solution

Explanation:

There are basically 3 types of solutions in biology,

1) Isotonic-Same concentration of solute and solvent inside  the grape and in the solution.

2)Hypotonic solution-More concentration of solvent in the solution than in the grape.

3)Hypertonic solution-More concentration of solvent in the grape than in the solution.

Now,

a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.

b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.

Archaean eon

Explanation:

You are in the Archean Eon era because the it was early in the Archean that life first appeared on Earth. The most two earlier of the formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth It began about 4 billion years ago with the formation of Earth’s crust and enlongated to the begining of the Proterozoic Eon 2.5 billion years ago; the latter is the second formal division of Precambrian time.

In the Archean eon there are unsual landscapes no rocks are preserved from this stage. The earliest terrestrial materials are not rocks but minerals.

Throughout the Archean, oceanic and island arc crust was produced semi-half way.

You cannot breathe because there was no oxygen on the Earth. Oxygen was only present in compounds such as water and chemical reactions change to carbon containing molecules that form simple living cells that does not require oxygen.
