Answer:

Option A

Explanation:

The rock fossils depict the history of life because they consist of several deposits of old age fossil in different layers of rock strata. The layer of rock strata which lies at the bottom of any rock deposits is the oldest layer. By examining this oldest layer one can determine the prevailing atmospheric condition at the time of its formation. Also, examining the remains of fossil can help us to understand the forms of life existing during that time.  

In this way all the layer of rock strata can be examined one by one from bottom (oldest) to top (youngest). This shall also allow us to understand the pattern of evolution of biological species with time.  

Hence, option A is correct

Bacteria undergo mitosis and meiosis in order to reproduce and increase genetic recombination.
Salsk061 [2.6K]

Answer:

The correct answer is (b)-False

Some people have their gall bladder surgically removed to the formation of gall stones. Describe the function of the gall bladde
sertanlavr [38]

Underneath the right side of the liver, the gallbladder is a pear-shaped organ.

<h3>What is the function of gall bladder?</h3>

Its primary function is to gather and concentrate bile, a digestive fluid made by the liver. The gallbladder is where bile is kept after the liver produces it. The gallbladder receives a signal from the stomach when you eat. Bile is released from the gallbladder when it contracts, and it travels through the gut via the major common duct. Bile combines with the food there and aids in digestion.

When the gallbladder is removed from a healthy person, there are rarely any obvious health or digestive issues, though there is a slight chance of diarrhea and fat malabsorption.
