The things that potatoes and bacteria have in common is that they both reproduce asexually. Thus option 4 is correct.
What is reproduction?Reproduction is defined as the biological process that creates new individual organisms from existing ones, also referred to as "offspring"
It can also be defined as the process by which identically minded organisms make new organisms.
There are two types of reproduction.
Sexual reproduction - It is defined as a method of reproduction whereby male and female gametes combine to create an offspring.Asexual reproduction - It is defined as a method of reproduction that doesn't modify the number of chromosomes or involve the fusing of gametes.Thus. the things that potatoes and bacteria have in common is that they both reproduce asexually. Thus option 4 is correct.

1340.40 grams of Iron is made to react with nitric acid, find mass of ferri nitrite produced. Use the given equation 2 Fe + 6HNO3 2Fe (NO3 + 3H₂
The mass of ferric nitrate, Fe(NO₃)₃ produced from the reaction given the data is 5792.44 g
Balanced equation2Fe + 6HNO₃ –> 2Fe(NO₃)₃ + 3H₂
Molar mass of Fe = 56 g/mole
Mass of Fe from the balanced equation = 2 × 56 = 112 g
Molar mass of Fe(NO₃)₃ = 56 + 3[14 + (16×3)] = 242 g/mole
Mass of Fe(NO₃)₃ from the balanced equation = 2 × 242 = 484 g
SUMMARY
From the balanced equation above,
112 g of Fe reacted to produce 484 g of Fe(NO₃)₃
How to determine the mass of Fe(NO₃)₃ producedFrom the balanced equation above,
112 g of Fe reacted to produce 484 g of Fe(NO₃)₃
Therefore,
1340.4 g of Fe will react to produce = (1340.4 × 484) / 112 = 5792.44 g of Fe(NO₃)₃

If a 22.4 L volume of a sample of gas has a density of 0.900 grams/L at 1.00 atm and 0.00°C. Given
the following gases, which could it be?
A. Ne
B. CO
C. CO2
D. Kr
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)

Recognize: What happens if a hypothesis is not supported.
Explain: Why do scientists practice scientific inquiry?
Describe: The behaviors scientists use in their work.
Answer:
If the initial hypothesis is not supported, you can go back to the drawing board and hypothesize a new answer to the question and a new way to test it. ... Either way, the process of experimentation often leads to whole new questions to explore.
Scientific inquiry uses evidence from observations and investigations to create logical explanations to answer questions related to science. Scientific inquiry is different from the scientific method. ... Scientific inquiry helps you think outside the box to understand the natural world.
Unlike social scientists, behavioral scientists collect empirical data and use experimental methods, including testing, controls and manipulated settings.

I am an alkali metal located in the third period of the periodic table. Who am I?
Answer:
Magnesium
Explanation:
It's an alkali metal and is in the third period on the period table. I'm sure
The alkaline earth metal found in period 3 of the periodic table is magnesium.The lightest structural metal is magnesium (Mg), an alkaline-earth metal from Group 2 (IIa) of the periodic table.
I am an alkali metal located in the third period of the periodic table. Who am I?
Six chemical elements in Group 1, the periodic table's leftmost column, make up the alkali metals.They are francium (F), cesium (Cs), rubidium (Rb), potassium (K), sodium (Na), and lithium (Li) (Fr). One of the chemical elements in the third row of the periodic table of the chemical elements is referred to as a period 3 element. Magnesium is regarded as a metal because it is a member of group2.Acid and metals react to produce salt and hydrogen gas.As a result, magnesium interacts with diluted hydrochloric acid to produce magnesium chloride (salt) and hydrogen gas. Magnesium is a silvery, light metal that makes up 2% of the Earth's crust but is not present in nature.Only in combination with other elements like carbon, calcium, and oxygen, as in the common mineral dolomite, could this versatile element naturally arise. Magnesium is a cofactor in more than 300 enzyme systems that affect a variety of biochemical processes in the body, including as protein synthesis, blood glucose control, blood pressure regulation, and muscle and nerve function [1-3].Magnesium is necessary for the oxidative phosphorylation, glycolysis, and generation of energy. Magnesium supports muscle and neuron function as well as energy synthesis in the body, among many other vital functions.Typically, low magnesium levels don't result in any symptoms.On the other hand, persistently low levels can raise your risk of osteoporosis, type 2 diabetes, high blood pressure, and heart disease. For the majority of individuals, daily doses under 350 mg are safe.The adverse effects of magnesium can include nausea, vomiting, diarrhea, and upset stomach in some people.Magnesium is POSSIBLY SAFE UNTIL TAKEN IN VERY HIGH AMOUNTS (more than 350 mg daily).To learn more about magnesium refer

Charlotte has some copper sulfate solution. She wants solid copper sulfate. Which technique should she use?
Answer:
She should use the crystalization technique
Explanation:
First, the copper sulfate solution should be filtered to clear any impurities.
By heating the solution of copper sulfate on a china dish, the excess water in the solution evaporates and leaves behind a saturated solution of copper sulfate.
Upon cooling this saturated copper sulfate solution, crystals of solid copper sulfate will be formed on the china dish.
In solid form, copper sulfate appears in triclinic-shaped crystals.

how many electrons does hydrogen need in order to have a full shell of valence electrons?
Answer:
One
Explanation:
In a hydrogen atom, the first outer shell only consists of two valence electrons, because it would already have one, the atom only needs one more.
It requires two electrons to completely occupy its outer shell, it frequently forms a single covalent bond with another atom. Because of this configuration, hydrogen can gain access to two electrons and completely occupy its valence shell.
What is Hydrogen?Hydrogen adheres to the duet rule because it only requires two electrons to completely occupy its valence shell. It deviates from the octet rule. Hydrogen only needs to form one bond. Because of this, H is always a terminal atom and never a central atom. Hydrogen is a chemical element with the symbol H and the atomic number 1.Hydrogen is the lightest element. Under normal conditions, hydrogen is a gas of diatomic molecules with the formula H2. It is colorless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is a more environmentally friendly alternative to methane, also known as natural gas. It is the most abundant chemical element, accounting for 75% of the universe's mass. Water, plants, animals, and, of course, humans contain massive amounts of hydrogen atoms.To learn more about valence electron refer to:

1. How much energy is required to heat 32.5g of water from 34°C to 75°C?
Answer:
5.850 kJ (of heat energy)
Explanation:
What we need:
[] The mass of the material = m = 32.5g
[] The temperature change that occurs = ΔT = 43
() 75 - 34 = 43
[] The specific heat capacity of the material = c
() This is the amount of heat required to raise 1 gram of that substance by 1°C
() For water, this is 4.186Jg°C
The equation to use:
Q = m * c * ΔT
Q = 32.5 * 4.186 * 43
Q = 5849.935 J
Q = 5.850 kJ

[tex]\boxed {\boxed {\sf 5569.85 \ Joules}}[/tex]
Explanation:
We are asked to find how much energy is required to heat a sample of water.
We will use the following equation:
[tex]q= mc \Delta T[/tex]
The mass of the water is 32.5 grams. The specific heat capacity of water is 4.18 Joules per gram degree Celsius.
The change in temperature is the difference between the final temperature and the initial temperature. The water's temperature is raised from 34 degrees Celsius to 75 degrees Celsius.
ΔT= final temp - inital tempΔT = 75 °C - 34 °C = 41 °CNow we know all three variables:
m= 32.5 g c= 4.18 J/g °C ΔT = 41 °CSubstitute the values into the formula.
[tex]q= (32.5 \ g)(4.18 \ J/g \textdegree C)(41 \ \textdegree C)[/tex]
Multiply the first 2 numbers together. The units of grams cancel.
[tex]q= 135.85 \ \ J/ \textdegree C(41 \ \textdegree C)[/tex]
Multiply again. This time, the units of degrees Celsius cancel.
[tex]q= 5569.85 \ J[/tex]
5,569.85 Joules of energy are required.
