Answer:
Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.
For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.
Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).
Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.
For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1
Answer:
Water and electrolyte absorption.
Explanation:
Digestion may be defined the process of breakdown of large food particles into the simpler substances with the help of enzymes and juices. The improper digestion can leads to various diseases.
The gastroenterologist concern that their is improper functioning in the bowel. The lower GI tract disorder affects the feces movement toward anus. The water and elelctrolyte absorption is worse affected and problem in the removal of the dietary waste.
Thus, the correct answer is option (A).
This current mass extinction is believed to be cause by human-related factors.
The 5th mass extinction was during the dinosaur era; which was demolished by the giant asteroid that hit Earth.
However, our 6th mass extinction (which makes me so sad); is cause by us....the human race. We're over hunting, over harvesting, taking away habitats that overall will also effect our ecosystem in a negative way.
Its easer to water because everything rotates around it
Everyone’s body is made of the same basic stuff. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms. Water makes up about two thirds of the weight of cells.
Cells are very small; most cells can only be seen through a microscope. Cells are the smallest living units that are capable of reproducing themselves. Each cell in your body was made from an already existing cell. All plants and animals are made up of cells. In this article, we will talk about the cells that make up You.
pre All the parts of your body are made up of cells. There is no such thing as a typical cell. Your body has many different kinds of cells. Though they might look different under a microscope, most cells have chemical and structural features in common. In humans, there are about 200 different types of cells, and within these cells there are about 20 different types of structures or organelles.
