(a) Name the process by which water passes from the blood to the dialysis fluid.
(b) Describe the process you have named in (a).
(c) Explain why water passes out of blood but proteins do not.​

Answers

Answer 1

Answer:

Healthy kidneys clean your blood and remove extra fluid in the form of urine. They also make substances that keep your body healthy. Dialysis replaces some of these functions when your kidneys no longer work. There are two different types of dialysis - hemodialysis and peritoneal dialysis. The following is about hemodialysis.

C. A paramecium is a single-celled organism that lives in ponds. It travels at a rate of 2,000 micrometers per second. What is the speed of the paramecium in meters per hour?

Answers

Answer:

7.2 meters per hour

Explanation:

It is given that,

The speed of a paramecium is 2,000 micrometers per second.

We need to find the speed of the paramecium in meters per hour.

We know that,

[tex]1\ \mu m=10^{-6}\ m[/tex]

and

1 hour = 3600 seconds

[tex]v=2000\ \dfrac{\mu m}{s}\\\\=2000\times \dfrac{10^{-6}\ m}{(\dfrac{1}{3600})\ s}\\\\=7.2\ \text{meters/hour}[/tex]

Hence, the speed of the paramecium is 7.2 meters per hour.

Terry bought a gold necklace at a pawnshop and was wondering if it was “real” gold. She decided to perform a density test. She placed the necklace in a graduated cylinder of water that had 47.00 mL of water and the water rose to 48.35 mL. She then weighed the necklace and found it to have a mass of 22.89 g. What is the density of Terry’s necklace?

Answers

Answer:

d = 16.96 g/mL

Explanation:

Given that,

Initial water level in graduated cylinder is 47 mL and final water level is 48.35 mL.

The weight of the neclace is 22.89 g.\

We need to find the volume of the necklace. We know that, density equals mass per unit volume. So,

[tex]d=\dfrac{m}{V_f-V_i}\\\\d=\dfrac{22.89\ g}{(48.35-47)\ mL}\\\\d=16.96\ g/mL[/tex]'

Hence, the density of Terry’s necklace is 16.96 g/mL.

Answer:

A

Explanation:

The new mine means the supply is high and the price is low, so she can afford the necklace

A  potassium isotope contains 19 protons, 19 electrons, and 21 neutrons, so the mass number is 40 as the mass number of the atom is the sum of the protons and the neutrons, the mass number is 40.

What is the significance of the mass number in the atom?

The mass number is significant as it is the sum of the number of protons and neutrons present in nucleus of an atom, which determines the atomic weight of an element and also determines its chemical properties and its position on the periodic table. Isotopes of an element have the same atomic number but a different mass number, so they have different properties than the original element.

Hence, a potassium isotope contains 19 protons, 19 electrons, and 21 neutrons, so the mass number is 40 as the mass number of the atom is the sum of the protons and the neutrons, the mass number is 40.

a cheetah can run 112km/h over a 100-m distance. what is this speed in meters per second

Answers

First convert the 112 km/hr ratio into m/s (meters per second). To do this you multiply 112 km with 1000 m/km (since there's 1000 m in one km). You get 112000 m. Then multiply 1 hr with 60 min/hr (since there's 60 min in one hr. You get 60 min, but you want seconds, so multiply 60 min with 60 s/min to get 3600 s. There you go! Your answer is the speed of 112000m/3600s, but you can simplify that to 31.11m/s (since the answer should be in ? meters per 1 second.

Also, the "100-m-distance" part of the question is just to throw you off, because one particular speed obviously stays constant over any distance. Hope that helps :)

Which of these is a property of a substance that is composed of atoms that are held together by metallic bonds?
It has a low melting point.
It can be flattened and bent.
It cannot be shaped into wires.
It does not conduct electricity.

Answers

Answer:

B: it can be flattened and bent

Explanation:

Metals are malleable and can be flattened. Metals are ductile and can be deformed and bent.

Metals are bonded together by metallic bonds.

Hence a substance that is composed of atoms that are held together by metallic bonds can be flattened and bent.

The property of a substance that is composed of atoms that are held together by metallic bonds is  it can be flattened and bent

What is metallic bond ?

Metals are malleable, ductile substance can be deformed when it is bent down, theses are bonded by metallic bond and can be flattened.

The metallic bond is a force of attraction which is responsible for holding the atoms together,  releases electrons to achieve the configuration of a noble gas.

in this type of bonding all the atoms lose their electrons from their outermost layers that move more or less freely between them, forming an electronic cloud

The metallic bond is the exceptional bond where the electrons are not present exclusively between a pair of atoms, but these are relocated among millions of them  called as  "sea of ​​electrons"  by cohesive bond.

(1 kilometer = 1,000 meters, 1 hour = 60 minutes, 1 minute = 60 seconds) Complete the steps necessary to convert 55 kilometers per hour to meters per second. Min 60 1,000 15.28 100 sec

Answers

Explanation:

55 kilometers per hour to meters per second

First we have to convert the kilometers to grams;

1 kilometer = 1,000 meters

This means we have;

55000 meters per hour

Converting hour to seconds;

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60 * 60 = 3600 seconds

We divide 55000 by 3600;

55000 / 3600 = 15.28 meters per second

The chemical symbol for silver oxide, an ionic compound used to make button batteries, is made of silver and
oxygen and has a chemical formula of Ag20.




Answer 2 and 1

Answers

Answer:

2 Silver Ions

1 Oxygen Ion

Explanation:

Edg2021

The chemical symbol for silver oxide is not Ag₂0. The correct chemical formula for silver oxide is Ag₂O.

Silver oxide (Ag₂O) is an ionic compound composed of silver ions (Ag⁺) and oxide ions (O₂⁻). It is commonly used in button batteries as a cathode material. In this compound, two silver ions combine with one oxide ion to form a stable structure.

The chemical formula Ag₂O indicates that there are two silver ions (Ag⁺) and one oxide ion (O₂⁻) in each formula unit of silver oxide. The subscript 2 after Ag indicates that there are two Ag⁺ ions present, while the absence of a subscript after O indicates that there is one O₂⁻ ion.

Hence, the chemical formulae are discussed above.
