<span>The sequence is as follows:
c, d, a, b, f, g, e
The impulse starts at the SA node that has its own contraction rhythm (but can be faster or slower depending on other impulses or hormones). That impulse travels then through the atria and is slowed down by the atrioventricular septum except for a region in the right atrium called AV node where the impulse has continuity. The impulse travels then to the ventricles through the AV bundle. The impulse continues through bundle branches to other fibers: Purkinje fibers. These Purkinje fibers cause then a contraction that goes from the apex of the heart and rapidly through the ventricles.</span>
Answer:
Olfactory sensory neurons (OSN).
Explanation:
Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.
Well, basically we can say that <span>Best Disease expresses itself more through the generations. The reason for that is because it is dominant. While we may say that the allele of the sickle cell anemia its indeed a recessive trait with 0% of chances, Best desease is a dominant trait with 50% of chances.</span>
DO U HAVE PHYSICS Because i do and yeah so
Answer:
The one who determines the gender of a new baby is the father, since he is the carrier of the X and Y sex chromosomes.
Explanation:
The sex chromosomes X and Y are called sex determinants, since the sex of the offspring depends on them:
- <em>XX</em><em> corresponds to the female sex.
</em>
- <em>XY</em><em> corresponds to the male sex.
</em>
A mother can only provide her offspring with X chromosomes, while the father can provide both X and Y chromosomes, so he is the one who determines the sex of a new child. In this case, the possibility of having a male or female child will always be 50:50
