Genetic inheritance is necessary for evolutionary change. It describes how genes are passed from one generation to the next.It might consequently initially seem surprising then, that genetic inheritance itself is rarely inculded in life research.  

The phenotype controlled by organelle genes exhibit maternal inheritance.The classic phenotype which exhibits maternal effects is coiling direction of snail shell.The phenotype that is seen in the offspring is controlled by the genotype of the mother.

1. Explain the relationship between surface area and absorption. Use an example of an organ to support your explanation.
san4es73 [151]

Small intestine is the organ which has villi contains large surface area for absorption.

The small intestine has a tendency to be the region of finest absorption ability for most drugs due to its large surface region, the presence of both energetic and passive absorption mechanisms, and close to neutral pH.

But, about ninety five percent of nutrient molecules are absorbed inside the small intestine. The absorption of most people of these molecules takes area in the second a part of the  small intestine, called the jejunum. Absorption refers to the movement of nutrients, water and electrolytes from the lumen of the small gut into the mobile, then into the blood.

The small intestine is right for absorption since it has a huge inner surface location. That is shaped due to the plicae circulates which undertaking many tiny finger-like systems of tissue called villi. The character epithelial cells also have finger-like projections, which can be referred to as referred to as microvilli.
