Allopatric speciation, also referred to as geographic speciation, is a method of the formation of new species due to isolation of the species from one another through geographic means.
The first step in this process is geographic isolation, which means that the original population is divided into two groups due to geographical reasons such as movement of continents or formation of water bodies.
Next, the species are subjected to different selection pressures due to their different environments. Eventually, the gene pool becomes very different for the two species due to the different selection pressures and because they are not allowed to mix.
Finally, after enough time passes, speciation occurs, which means that the two populations cannot breed to form fertile offspring.
Answer:
The correct answer is A. Fat
Explanation:
Fat is one of the macronutrient that is present in our food and fat is accumulated in the body on the liver and in adipose tissue and provide storage form of energy to the body. So fat accumulation contributes to weight gain.
Fats contributes to more calory per gram than other macronutrient like carbohydrates and proteins, therefore, reducing the amount of fat by taking low calory diet which have less fat amount is important to reduce weight.
Therefore here to lose some weight by powerlifter fat will likely need to be monitored closely and possibly limited.
Answer;
cells are very different but have similar properties
Explanation;
-Even though there are many different types of cells, they all share similar characteristics. All cells have a cell membrane, organelles organelles, cytoplasm, and DNA. All cells are surrounded by a cell membrane, all cells contain organelles, all cells contain cytoplasm and all cells contain DNA.
-Cells may differ in their number such that some organisms are made of only a single cell while other organisms are made of billions of cells
