Cerrena [4.2K]

Procreation comes from pairing. In different phrases you have 2 codes for each little thing. you have the code from the father and the code from the mother. evaluate the code for blood. you're attentive to that there are 4 varieties of blood variety O, variety A and variety B and variety AB. If mom has 2 codes for her blood, enable us to declare O and O and father has 2 codes for his blood enable us to declare O and A There are a sequence variety of combinatins the 1st mom O can combine with father O, OO The 2d mom O can combine with father A, OA. the 1st mom O can combine with father A, OA The 2d mom O can combine with father O, OO the baby is going to have the two OO or OA. If the baby has OO the the baby has no selection different than to have blood variety O because of fact the expressed phenotype. If the baby has OA the A is dominate and it takes expression. subsequently the only way a recessive allele could be expressed is that if and on condition that there are 2 recessive allele as interior the case of OO. Now do the different combinations mom OO mom OA mom AA mom OB mom BB mom OO can combine with father OO making OO mom OO can combine with father OA making OA mom OO can combine with father AA making OA mom OO can combine with father OB making OB mom OO can combine with father BB making BB The recessive allele is expressed if and on condition that the two codes are recessive. What if mom is dominant A. mom AA mom OA can a recessive allele be produced particular If and on condition that the recessive O of the mother combines with a recessive O of the father. subsequently a mom dominant A might desire to be coded as OA and a father dominant A might desire to be coded as OA. the baby can get carry of mom O blended with the father O and be OO, the recessive. the baby is recessive even whilst the mothers and dads are dominant because of fact the mothers and dads carried the recessive allele. this might ensue if and on condition that the two mothers and dads carry the recessive allele. pass via the mixture mom OA Father AA you will by no capacity get a recessive phenotype expressed

Fisher was found lying on his back. Is it likely that his body was moved after death? Why or why not?
Tpy6a [65]

Answer:

Is it likely that his body was moved after death? The answer is NO

Why or why not?

This is due to postmortem staining seen on his back which would have been observed on other parts of the body if the body was moved after death

Explanation:

Livor mortis: is the stage where the heart stops pumping blood through the circulatory system causing blood accumulation at the lowest point of the body. It's also called postmortem stain.

It helps in judging the time of death for a body, the location and position of the body if it's at the spot.

A receptor can directly open a channel and thereby exert a(n) ____ effect, or it can produce slower but longer ____ effects.​
svlad2 [7]

Answer: ​ionotropic; metabotropic

Explanation:

A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.

Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.

The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
