Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offsprin

g
An incomplete dominance cross is performed between a bird that is homozygous for red feathers and a bird that is
homozygous for blue feathers. Purple offspring result. Then, two of the purple offspring are crossed. According to the Punnett
square for this cross, how many of the offspring from the second cross will have a feather color that results from incomplete
dominance?

After ovulation, the corpus luteum releases _____ to prepare the endometrium for implantation.
ivolga24 [154]

After ovulation, the corpus luteum releases progesterone and estrogen to prepare the endometrium for implantation.

What is ovulation?

Ovulation is the process in which a mature egg is released from the ovary. After it's released, the egg moves down the fallopian tube and stays there for 12 to 24 hours, where it can be fertilized.

Sperm can live inside the female reproductive tract as long as five days after sexual intercourse under the right conditions.

Your chance of getting pregnant is highest when live sperm are present in the fallopian tubes during ovulation.

In an average 28-day menstrual cycle, ovulation typically occurs about 14 days before the start of the next menstrual period.

However, each person's cycle length may be different, and the time between ovulation and the start of the next menstrual period may vary.

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂
