Answer:
SV = 30 ml/ beat.
HR = 80.
Explanation:
The formula to calculate SV is as follows:
SV = EDV- ESV.
Here EDV = 90ml (end diastolic volume), ESV = 60ml (end systolic volume) ans SV is stroke volume.
SV = 90-60
SV = 30ml/beat.
The formula to calculate HR is as follows:
HR = CO/SV
Here, HR is heart rate, CO is cardiac output = 2,400 ml/min and SV is stroke volume = 30ml/beat
HR = 2,400/30
HR = 80.
Thus, the SV is 30ml/best and HR is 80.

Answer:
Cross a non-floppy-eared male to a floppy-eared female and observe if males offspring have the floppy ear trait
Explanation:
Mammals (e.g. dogs) have two sex chromosomes: X and Y. In the XY sex-determination system, the female gamete (i.e., the ovum) contributes to an X chromosome, while the male gamete (i.e., the sperm) contributes either an X chromosome or a Y chromosome: normal females are XX and normal males are XY. In consequence, a male always inherits its X chromosome from the mother and its Y chromosome from the father. In this case, the presence of the floppy ear trait in all males F1 offspring obtained by crossing a non-floppy-eared male to a floppy-eared female indicates that this trait is linked to the X chromosome because males inherit the floppy ear trait from the mother.
C: The polar bear will probably not survive.
The kinesthetic system relies on receptors in the vestibular nerve to relay information to the brain.
<h3>What is vestibular nerve?</h3>
- The vestibular nerve transmits motion and positional information.
- The vestibular apparatus, ocular muscles, postural muscles, brainstem, and cerebral cortex all communicate with each other in unison as part of the vestibular system.
- The vestibulocochlear nerves have two main categories of unique sensory function.
- The cochlear nerve controls hearing, while the vestibular nerve controls balance and equilibrium.
- The vestibule and cochlea, which are monitoring receptors in the inner ear, are the origin of the vestibulocochlear nerves.
- The most likely causes, according to researchers, are viral infections of the inner ear, swelling around the vestibulocochlear nerve, or viral infections that have already spread to other parts of the body.
