Answer:
is primarily responsible for a movement
Explanation:
Working muscles are called agonists or prime movers because to complete a movement they produce major force. These muscles are primarily responsible for the occurrence of a movement. By contracting they make a range of motion for example during the up phase of push up the triceps brachii contracts which produce a shortening contraction.
The muscles that oppose the action of agonists are called antagonists. So antagonists are responsible for the returning of arm or leg in its original position. So the correct answer is- is primarily responsible for a movement.
The correct answer is centrosome.
<span>The centrosome is the main microtubule organizing centre of the animal cell and it is involved in the regulation of cell-cycle progression. During the mitosis, the centrosome microtubules can interact with the chromosomes to build the mitotic spindle.</span>
Each aluminium ion should have a charge of +2, because the sum of oxidation numbers must be zero.
The uncharged aluminium atom must lose two electrons to become an ion with +2 charge.
what has to happen to an uncharged aluminum atom so that it will bond with oxygen?
It has to lose electrons to become positively charged, so it can attract a negatively charged oxygen ion
The risk of recurrence of a trait based on known incidence in a population refers to the empiric risk.
<h3>What is empiric risk?</h3>
Disorder present in a family member will reoccur in other family member after some period of time.
Cancers are very difficult to treat so it has high rate of recurrence such as leukemia it has 9% to 29% recurrence rate depending upon risk.
The recurrence chance for Down syndrome is nearly 1%.
The chance of recurrence risk in future offspring is 3% - 5% if a parent or sibling is affected with a disorder.
Therefore,the risk of recurrence of a trait based on known incidence in a population refers to empiric risk.

While there is no graph provided and I cannot find the graph online, I will base my answer through theory.
In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
