Because the rock is laid down over time, the oldest rock (and fossils or whatever) will be in the lowest layer. As you go up, the age decreases - you are looking at younger rocks.
This doesn't tell you the *absolute* age of the rocks - you can't say from this evidence whether they are 100 million or 500 million years old. But you can see changes over history and you can get an ordering in time.
Answer: D. large, phagocytic cells that can leave the circulation and enter the tissues of the body
Explanation:
Macrophagus are the type of white blood cells. These are responsible for providing immunity to the host against the pathogenic attack. These cells engulfs and digest the foreign agents like microbes, cellular debris, cancer cells and unwanted cellular components. This process is called as phagocytosis.
The monocytes transforms into macrophagus in conditions of infection and tissue damage. These monocytes leaves the blood stream and reach at the site of affected tissue or organ.

Answer:
Explanation:
let's say "cc" represents the colorblindness gene, since it is a recessive trait. a male with colorblindness would have a "cc", and the woman is a carrier of the trait, so she would be "Cc".
if we draw out the punnet square, we can come to the conclusion that 50% of the children have "Cc" and the other 50% have "cc"
half of the children are carriers are carriers and half have the color blindness gene.
