So here let's first find the amount of children every santa, in total, sees in one day. So if there are 400 santas, and each sees 125 children, you can just multiply 400 by 125 to see how many children all the Santas see in one day.
400 * 125 = 50,000
Now, since there are 30 days which all the santas see 50,000 children, you can then multiply 30 by the 50,000 children to get how many children are seen by Macy's Santas in a month.
30 * 50,000 = 1,500,000
So 1,500,000 children are seen by Macy's Santas.
The number attendees that would most likely be interested in Darnell's booth is : ( A ) 1 : 3
Aim : The question is all about the ratio of self employed vet at the trade show to the total number of Vets at the trade show
<u><em>Assuming </em></u>
Number of self employed veterinarians = 20
Number of Veterinarians = 60
<h3>Determine the number of self employed vet that are interested in Darnell's booth </h3>
Total number of Vet = 60
number of self employed Vet = 20
= number of self employed / Total number of Vet
= 20 / 60
= 1 : 3
Hence we can conclude that The number attendees that would most likely be interested in Darnell's booth is : ( A ) 1 : 3

Answer:
The correct answer would be Atria push blood into the ventricles and Ventricles push blood out of the heart.
In humans, four chambered heart is present with two atria and two ventricles.
Deoxygenated blood from all over the body is passed into the right atrium through vena cava (superior and inferior).
Simultaneously, oxygenated blood from the lungs is passed into the left atrium of the heart with the help of pulmonary vein.
Both the atria contract at the same time to drain their blood into respective ventricles.
The ventricles undergo relaxation while receiving blood.
The valves present between the atria and ventricles (tricuspid and bicuspid valve) ensures that the blood flows in one way direction only. They shut down as the ventricles contract and produce the sound "lub".
The ventricles contract simultaneously to pump blood out of the heart. The right ventricle pumps deoxygenated blood into pulmonary artery which takes the blood to the lungs for oxygenation.
The left ventricle passes the oxygenated blood through aorta to all the parts of the body.
The pulmonary and aortic valves prevent the back flow of blood and shut at the same time which creates second sound called as "dub".
The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
