The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
Function of enzymes in catalyzing biological reactions Enzymes are catalysts, which are things that increase the rate of a reaction, but does not get used up during the reaction. Structure determines function. A change in structure => a change in function. Important biological reactions catalyzed by enzymes: Metabolism.
The enzyme's shape fits its substrate's shape, thus allowing the enzyme to catalyze the appropriate reaction.

Answer:
<u>The four stages of labor:</u>
The first stage of labor
In the first stage of labor the Thinning (effacement) and opening (dilation) of the cervix. This is called effacement and dilation(of the cervix).
The process is explained systematically and its very very simple to say that When the cervix dilation happens and mucus strings from vulva placenta is delivered then the child birth is near.
Explanation:
- <u>The first stage of labor has three parts:</u>
- Early labor:The cervix opens to 4 centimeters. <em>The female will probably spend most of early labor at home.</em> The female should keep herself busy in doing her usual activities. Relax, rest, drink clear fluids, eat light meals if she wants to, and keep track of her contractions.
- Active labor: The cervix opens from 4 to 7 centimeters. This is when the female should head to the hospital. When she has contractions every 3 to 4 minutes and they each last about 60 seconds, it often means that the cervix is opening faster (about 1 centimeter per hour).
- Transition to second stage: The cervix opens from 7 to 10 centimeters. For most women, this is the hardest or most painful part of labor. This is when the cervix opens to its fullest.
- <u>Second stage of labor</u>
- The baby moves through the birth canal
The second stage of labor begins when the cervix is completely dilated (open), and ends with the birth of the baby.<em> Contractions push the baby down the birth canal, and the female may feel intense pressure, similar to an urge to have a bowel movement.</em>
- <u>Third stage of labor</u>
- Afterbirth: The uterus continues to contract to push out the placenta (afterbirth).
- <u>Fourth stage of labor</u>
- Recovery:Nursing right after the birth of the baby will help the uterus to contract and will decrease the amount of bleeding.
Answer:
Our eyes can trick our brain in some manner. When the eye see an image, our brain assumes that the image being seen is a image which had been seen in the past. Therefore, our brain is tricked into believing that the image which is being seen is of something which has been visualized before whereas in actual it is a new image. Hence, this is the relationship between seeing of the eyes and perceiving of the brain.
