Answer:
Explanation:
As the inheritance is X-linked,recesson so for expression of muscular dystrophy in any given muscle,
enh1+ /enh1 + = Shows muscular dystrophy in heart (Homozygous for -)
enh2+/enh2+ = Shows no muscular dystrophy in arms (Homozygous for +)
enh3-/enh3+ = variabl or mosaic for muscular dystrophy in leg muscles (Hetrozygous for enh3)
The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.
The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.
This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.
The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.
The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.

A: yes
Explanation:
B: Sample three is a mixture of the suspect and victims. Putting it simply, if you line up the victims DNA and remove it from sample 2 you are left with a sample of DNA that is identical to the suspects.
Prokaryotes- lack a cell nucleus, unicellular, in the bacteria and archaea domain, lack mitochondria and chloroplast, microscopic
eukaryotes- contains a cell nucleus, multicellular, only in the eukarya domain, contains mitochondria and chloroplast, not microscopic
