Answer:
Darkened shapes are recessive
Explanation:
In the pedigree shown, we can see that 2 parents that are unshaded shapes have 2 children that are shaded shapes. This would be impossible if shaded shapes were dominant and unshaded shapes were recessive. This is because parents that have a recessive trait have 2 of the same alleles. So if 2 parents that both have a recessive trait have a child, the child will definitely have that trait. But we can see that this is not the case, the parents have 2 offspring that have different phenotype from the parents. This must mean the parents are heterozygous, meaning that they both have 2 alleles that are different. The dominant allele masks the recessive allele, so the dominant allele is expressed. In this case, the children inherited 2 recessive alleles, 1 from each parent, making them have a different phenotype from the parents.

The missing words are circle - shaped chromosome.
Hope This Helps You!
Good Luck :)

The type of microscope which would be the best tool to use to view the surface of a bacterial cell is a Scanning electron microscope.
This is because it can be used to look at the surface of objects at high resolution. Maximum magnification: Approximately 500,000x. Best for: Looking at surfaces of objects
<h3>What is a Microscope?</h3>
This refers to an optical instrument that is used for viewing very small objects and can be magnified several hundred times.

Ooh this will be good
So blood let’s say starts in the left atrium where it goes down through the mitral valve into the left ventricle. From the left ventricle of the blood is pushed through the aorta and from there through the various branches of the body eventually allowing oxygen rich blood to flow all across the body. Once this blood is picked up by veins as deoxygenated blood it goes back to the heart through the inferior and superior vena cava. From there the deoxygenated blood is sent into the right atrium, through the tricuspid vale into the right ventricle, through the pulmonic valve into the pulmonary artery and into the lungs for re-oxygenation. The re-oxygenated blood (oxygen rich blood) now goes through the pulmonary veins into the left atrium and the cycle beings again.
Remember this, Left side of heart is for oxygenated blood, Right side of heart is for deoxygenated blood.
Artery takes oxygen rich blood away from heart itself
Vein takes oxygen poor blood back into the heart
Exceptions, Pulmonary Artery takes oxygen poor blood away from heart and into lungs
Pulmonary vein takes oxygen rich blood into the left atrium to be pushed to the rest of e body.
