What charts, tables, or drawings would clearly show what you have learned in this lab?
Each chart, table, or drawing should have the following items:
A: An appropriate title
B: Appropriate labels
Lab: Heredity and Punnett Squares
Answer:
I can use a dichotomous key. It helps me classify objects by sorting it out with "yes" and "no" questions.
or
I can use a Punnett Square. It helps me classify what genes the offspring will receive simply by figuring out the recessive and dominant genes as well as the hetzygous and homzygous.
Now give an example of which ever chart you choose by drawing it if that is required. For the Punnett Square label each of the squares Top right Hetzygous, top left dominant, bottom left recessive, bot-tom right homzygous. And for the dichotomous key put a 5-7 length branch showing the animals that have fur, can breathe under water, what cannot or doesn't have those traits. or something similar
Hopefully this helps :)

If the trend in a property is periodic, it means it will
a) look terrible if the teacher wears is it
b) only be found in elements next to each other
c) only be found on one row of the periodic table
d) repeat
Answer:
d) repeat
Explanation:
If the trend in a property is periodic, it means it will repeat on the periodic table.
Periodic properties on the table have a constant pattern as we move up or down a group or across a period from left to right.
This helps to predict some of the salient properties of elements as we move through the periodic table. For example, on most periodic groups, metallicity increases as we move down the group and it decreases across the period.Please help me thanks so much....I’ll mark you?!?!:))))

To see which reaction will happen we need to see the reactivity series of metals which shows the order of reactivity of metals, which displaces which. So option c is the correct option
What is displacement reaction?Displacement reaction is a reaction in which one atom replaces other atom from a molecule on the basis of reactivity strength. It is done by following reactivity series which states the increase order of reactivity of metals.
So in C option Li is a more reactive metal than Zn so Li can displace Zn from the Zinc carbonate Whereas in other option Platinum, Copper, Manganese are less reactive than Iron in Ferric chloride, Potassium in Potassium nitrate and calcium in Calcium oxide according to reactivity series. So In only option c, reaction will go in forward direction.

the molar heat capacity of ice is 37 and the molar heat capacituy of liqyid water is 76. what can be concluded about the relatice magnitudes fo the heat of fusion of ice at 263 k
Answer:
ΔH 263 < ΔH 273
Explanation:
From the given information
According to Kirchoff law:
[tex]\Delta H_2 = \Delta \ H_1 + \Delta \ (c_p) ( \Delta T)[/tex]
[tex]\Delta H_2 = \Delta \ H_1 + (76-37) \times ( 273 - 263)[/tex]
[tex]\Delta H_2 = \Delta \ H_1 + (39) \times (10)[/tex]
[tex]\Delta H_2 = \Delta \ H_1 + 390[/tex]
Thus, [tex]\Delta H_2[/tex] at 273 is greater than [tex]\Delta \ H_1[/tex] at 263
∴
ΔH 263 < ΔH 273

how can having a medical condition affect the delivery of molecules to cells in the body?
Answer: Having a medical condition affect the delivery of molecules to cells in the body because your body may not receive sufficient oxygen or glucose or amino acid molecules which in turn will not allow for it to preform properly. A person may experience fatigue, or difficulty breathing, or he or she may not be producing enough of a certain hormone.
Explanation:
A medical condition can affect the delivery of molecules to cells in the body due to the inability of the body cells to function properly.
A medical condition refers to a condition that deviated from a normal state of mind. Most especially, it could be an illness, disease, or disorder.
When the body is infected with a disease or illness, the immune system will not be able to recognize or fight disease-causing organism which is usually known as pathogens.
Cells become weak and they don't perform their required activates such as the:
production of enzymes needed to break down macromolecules into simpler molecules, and;delivery of molecules to other cells of the body.Learn more about cells here:

Answer:
[tex]16.1\times 10^3\ \text{g}[/tex]
[tex]16.1\times 10^{6}\ \text{mg}[/tex]
[tex]16.1\times 10^{9}\ \mu\text{g}[/tex]
Explanation:
Mass of dog = [tex]16.1\ \text{kg}[/tex]
[tex]1\ \text{kg}=10^{3}\ \text{g}[/tex]
[tex]1\ \text{kg}=10^{6}\ \text{mg}[/tex]
[tex]1\ \text{kg}=10^{9}\ \mu\text{g}[/tex]
So,
[tex]16.1\ \text{kg}=16.1\times 10^3\ \text{g}[/tex]
[tex]16.1\ \text{kg}=16.1\times 10^{6}\ \text{mg}[/tex]
[tex]16.1\ \text{kg}=16.1\times 10^{9}\ \mu\text{g}[/tex]
Mass of the dog in the other units is [tex]16.1\times 10^3\ \text{g}[/tex], [tex]16.1\times 10^{6}\ \text{mg}[/tex] and [tex]16.1\times 10^{9}\ \mu\text{g}[/tex].
The mass of a deuterium nucleus 21H is less than its components masses. Calculate the mass defect.________ amu
Answer:
The mass defect of a deuterium nucleus is 0.001848 amu.
Explanation:
The deuterium is:
[tex]^{A}_{Z}X \rightarrow ^{2}_{1}H [/tex]
The mass defect can be calculated by using the following equation:
[tex]\Delta m = [Zm_{p} + (A - Z)m_{n}] - m_{a}[/tex]
Where:
Z: is the number of protons = 1
A: is the mass number = 2
[tex]m_{p}[/tex]: is the proton's mass = 1.00728 amu
[tex]m_{n}[/tex]: is the neutron's mass = 1.00867 amu
[tex]m_{a}[/tex]: is the mass of deuterium = 2.01410178 amu
Then, the mass defect is:
[tex]\Delta m = [1.00728 amu + (2- 1)1.00867 amu] - 2.01410178 amu = 0.001848 amu[/tex]
Therefore, the mass defect of a deuterium nucleus is 0.001848 amu.

Which statement correctly describes gravity?
an attractive force that acts between all objects through contact
an attractive force that acts between all objects without contact
a repulsive force that acts between all objects through contact
a repulsive force that acts between all objects without contact
Answer:
I'd pick B, because gravity acts in between all object WITHOUT contact to each other. Gravity is all around us, we make contact with certain materials we use everyday, but objects don't contact to gravity. In certain terms, scientists are still not sure the REAL meaning of gravity, just how it works.
Explanation:
Pick B.

Answer: within the Earth’s atmosphere, heat is transferred mostly by convention. When the air near the ground is heated, its particles move more rapidly. These particles bump into each other and move further apart. The air becomesless dense. Cooler, denser air sinks towards the surface, forcing the warmer, less dense air to rise. The upward movement of the warmer air and the downward movement of the cooler air forms convection currents.

For the following reaction, 22.5 grams of iron are allowed to react with 35.0 grams of chlorine gas . iron(s) chlorine(g) iron(III) chloride(s) What is the maximum mass of iron(III) chloride that can be formed
Answer:
53.31g of FeCl3
Explanation:
The equation of the reaction is given as;
2Fe(s) + 3Cl2(g) --> 2FeCl3(s)
From the stochiometry of the reaction;
2 mol : 3 mol : 2 mol
112g : 213g : 324.4g
Converting the masses given to moles;
Number of moles of Fe = mass / molar mass = 22.5 / 56 = 0.4018
Number of moles of Cl2 = mass / molar mass = 35 / 71 = 0.4930
In this reaction, the limiting reactant is Cl2
213 g of Cl2 produces 324.4g of FeCl3,
35g of Cl2 would produce xg of FeCl3
213 = 324.4
35 = x
x = (35 * 324.4) / 213 = 53.31g
What NaCl concentration results when 284 mL of a 0.850 M NaCl solution is mixed with 467 mL of a 0.380 M NaCl solution
Answer:
0.558 M.
Explanation:
Hello!
In this case, when computing the resulting concentration of the solution after a mixing process, we first need to compute the moles provided by each solution:
[tex]n_{NaCl}^{sol1}=0.284L*0.850mol/L=0.2414mol\\\\n_{NaCl}^{sol2}=0.467L*0.380mol/L=0.1775mol[/tex]
So the total number of moles are:
[tex]n_T=0.2414mol+0.1775mol=0.4189mol[/tex]
And the total volume which is additive:
[tex]V_T=0.284L+0.467L=0.751L[/tex]
Therefore, the resulting molarity of sodium chloride is:
[tex]M=\frac{0.4189mol}{0.751L}\\\\M=0.558M[/tex]

Explanation:
The answer is primary
There are three types of alcohol one is primary second is secondary and third is tertiary. Therefore, the given alcoholic compound CH[tex]_3[/tex]CH[tex]_2[/tex]CH[tex]_2[/tex]OH is a primary alcohol.
What is alcohol?Alcohol is a chemical molecule with a functional group called hydroxyl linked to a saturated carbon atom.
Alcohols classified as primary have just one alkyl group on which the carbon atom of the hydroxyl group (OH) is connected. Secondary alcohols are those that have two alkyl groups on either side of the carbon atom of the hydroxyl group. In tertiary alcoholic group, the carbon that is bonded to hydroxyl group is bonded to three alkyl groups. the given alcoholic compound CH3CH2CH2OH is a primary alcohol.
Therefore, the given alcoholic compound CH3CH2CH2OH is a primary alcohol.
