How would relaxing the smooth muscles in arteries affect blood pressure ?
zloy xaker [14]
When you relax the smooth muscles in arteries, it affects the blood pressure quite a lot. If you're a up and running person, you're most likely not always relaxed. Although - if you manage to relax, it would cause your blood pressure to lower from a high rate, to a much lower rate. That's the main outcome of this.

Trisomy 21 can be caused by nondisjunction of chromosome 21, or by inheriting a Robertsonian fusion of chromosome 21 attached to
OLga [1]

Answer:

6 in total; 3 viable and 3 non-viable

Explanation:

Robertsonian translocation is one of the types of structural alteration in chromosomes, in other words, a rearrangement between chromosomes, which can occur between five pairs of acrocentric chromosomes (chromosomes with the centromere close to the end of one of the "arms"): 13, 14, 15, 21 and 22.

An individual who has Robertson's translocation between chromosomes 14 and 21 generally has only 45 chromosomes.

In addition, a carrier of this type of translocation can theoretically produce 6 types of gametes, however 3 of them are not viable.

As for the three remaining gametes: One is normal, and among the other two, one is balanced and the last is unbalanced.

So, theoretically, when combining a normal gamete, the probability of a child with down syndrome being born through these conditions is 1/3 (considering that the probability of producing a certain type of gamete is equal for the three types).

Which coin paradox calls for the ability to assess when more force is needed?
krek1111 [17]
The answer to this question would be: the more force used, the less effective it is.

Sometimes, more force in counterinsurgency can cause a less effectivity. It was called paradox because with more force you should expect more results and more efficiency. But more force could mean higher possibility for collateral damage which can cause loss, not gain. An overwhelming force also might be pictured as brutality.
