Mendel crossed tall pea plants with short pea plants. the offspring were all tall plants.
1. Which allele is recessive?
2. Which allele is dominant?

please hurry

Answer:
1. Allele for shortness (t)
2. Allele for tallness (T)
Explanation:
Gregor Mendel performed numerous experiments using pea plants (Pisium sativum). He tested the height traits of pea plants by crossing tall pea plants (TT) and short pea plants (tt) to obtain offsprings that were all tall (Tt) in the first filial generation (F1).
This is possible because the allele for tallness is DOMINANT while the allele for shortness is RECESSIVE. This means that tallness allele (T) will mask the phenotypic expression of shortness allele (t) when in an heterozygous state (Tt) as in the F1 generation.

Answer:
See Explanation
Explanation:
Volume of base used = (31.79 - 1.6) + (32.12 - 0.98) + (42.87 -13.21)/3 = 30.34 cm3
Volume of acid used = (24.86 - 0.42) + (24.11 - 0.11) + (27.67 -3.42)/3 = 24.23 cm3
For trial 1= number of moles of HBr = 24.44/1000 * 0.3 = 0.0073 moles
For trial 2= number of moles of HBr = 24/1000 * 0.3 = 0.0072 moles
For trial 3= number of moles of HBr = 0.0089 moles
HBr(aq) + KOH(aq) -----> KBr(aq) + H2O(l)
One mole of base is required to neutralize one mole of acid.
From CAVA/CBVB =nA/nB
CAVAnB = CBVBnA
CB = CAVAnB/VBnA
CB = 0.3 * 24.23 * 1/30.34 * 1
CB = 0.24 moldm-3
number of moles of KOH = concentration * volume
number of moles = mass/molar mass
molar mass of KOH = 56 g/mol
mass/56 = 0.24 * 30.34/1000
mass = 0.24 * 30.34/1000 * 56
mass =0.408 g of KOH

44.5 g Al2(SO4)3
Explanation:
# moles Ba(NO3)2 = (0.543M)(0.717 L)
= 0.389 mol Ba(NO3)2
Now we use the molar ratios,
0.389 mol Ba(NO3)2 ×(1 mol Al2(SO4)3/3 mol Ba(NO3)2)
= 0.130 mol Al2(SO4)3
0.130 mol Al2(SO4)3 × (342.15 g Al2(SO4)3/(1 mol Al2(SO4)3)
= 44.5 g Al2(SO4)3

Need help on this question asap please please I’m going to really appreciate it
Answer:
0.11 moles
Explanation:
The equation of the reaction is;
2SO2 + O2 ------>2SO3
Number of moles of O2 in 3.42 g = 3.42g/32 g/mol = 0.11 moles
Hence, 0.11 moles of O2 is consumed when 3.42 g of O2 reacts with SO2 to form SO3.

Calculate the molarity of a solution that contains 0.75 moles of lithium fluoride, LiF, in a 65 mL solution.
The molarity (M) of a solution is 11.5 M that contains 0.75 moles of lithium fluoride, LiF in a 65 ml of solution.
What is Molarity ?Molarity (M) is defined as the number of moles of solute dissolved in 1L of solution. Molarity is also known as Molar concentration. The S.I Unit of Molarity is molar (M) or mol/L.
How to find molarity of a solution ?Molarity (M) = [tex]\frac{\text{Number of moles of solute}}{\text{Volume of solution (in liters)}}[/tex]
From the above definition it is clear that the volume of solution is in liter. In question the volume of solution is given in ml.
So, convert 65 ml into l.
65 ml = [tex]\frac{65}{1000}[/tex] = 0.065 l
Now, put the values in above formula, we get that
(M) = [tex]\frac{0.75}{0.065}[/tex] = 11.5 M
Thus, the molarity of a solution is 11.5 M that contains 0.75 moles of lithium fluoride, LiF in a 65 ml of solution.

Agustina was standing on the edge of a cliff of unknown height holding a bowling ball. She wanted to find the height of the cliff. She worked with Maite to time the how long the bowling took to fall to the bottom of the cliff. Maite timed the drop at 9.4 seconds on each of their 10 trials. The bowling ball started at rest on each of the trials. What distance did the bowling ball fall in each trial?
Answer:
433 m
Explanation:
Since the fall represents motion under gravity, we use the equation
s = ut - 1/2gt² where s = height of cliff or distance bowling ball falls through, u = initial velocity of bowling ball = 0 m/s(since it starts from rest), t = time = 9.4 s and g = acceleration due to gravity = -9.8 m/s².
So, substituting the values of the variables into the equation, we have
s = 0 m/s × 9.4 s - 1/2 × 9.8 m/s² × (9.4 s)²
s = 0 m - 1/2 × -9.8 m/s² × 88.36 s²
s = 1/2(865.928 m)
s = 432.964
s ≅ 433 m

URGENT!!!
Which statement explains why an increase in molality increases the boiling point of a solution? The addition of solute decreases the solvent’s vapor pressure. A higher temperature must then be applied to overcome the change. The addition of solute increases the solvent’s vapor pressure. A higher temperature must then be applied to overcome the change. The addition of solute increases the solvent’s ability to boil. The solute’s molecules repel the solvent’s molecules, giving them higher binding energy and hence the need for higher temperature.

Structures and Forces - What is force and external forces.
Question 1) Jacob and Ravleen are moving furniture. They need to move the filing cabinet over 6 feet and it is very heavy. Jacob wants to apply force and push it by putting his hands on point A because he thinks it would be easier to move it from the top as there is less weight on the top. Ravleen says it's better to push at point B because the center of gravity is lower. Which person is correct and EXPLAIN why and what may happen if it is pushed in the wrong spot.
Answer:
The restoring force that prevents the furniture from tipping over when pushing the furniture towards the right, F= W × D
Where;
W = The weight of the furniture
D = The horizontal distance from the center of gravity of the furniture, CG and the to the lower right corner of the furniture
Given that A > D, for the furniture to tip over when pushing above the CG, we have;
F1 × A ≤ W × D
∴ F1 << W or for a force much smaller than W, the weight of the furniture applied above the center of gravity, the furniture will tip over
However when the force F2 is applied, where C < D, we have for no tipping over;
F2 × C ≤ W × D, therefore, given that C < D, when a force much higher than the weight, W, is applied at F2, the furniture will remain upright
Therefore, it is better push at a point lower than or equal to the center of gravity, whereby the point B is lower than the center of gravity, it is better to push at point B, Ravleen is correct and it is better to push at point B because the center of gravity is lower
If the furniture is pushed at the wrong spot it may tip over
