You've made the hypothesis that the higher the density of a rock, the higher the temperature at which it will melt, because a de

D. the temperature at which the rock melts

Explanation:

The dependent variable in this context is the temperature at which the rock melts.

The density of the rock is the independent variable.

  • An experiment is usually made up of dependent and independent variables.
  • The dependent variable is the effect in an experiment. Here we see that the reason why the rock melts at a higher temperature is because it has a higher density and it contains more materials.
  • The independent variable is the density of the rock. It is the cause.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>

3. The time between the end of ventricular systole to the beginning of atrial systole.
amid [387]

Answer:

The time between the end of ventricular systole to the beginning of atrial systole is 100 ms or 0.1 seconds.

Explanation:

Ventricular systole is the removal of blood from the heart by pumping through aorta and pulmonary vein. Both aorta and pulmonary vein receive the blood from the heart. Aorta receives oxygenated blood and pulmonary vein receive deoxygenated blood, while atrial systole is the addition of blood into the ventricular from vena cava and pulmonary artery due to contraction of heart. This process occurs in 100 ms.
