Rice, bread, pasta, and snacks made from white flour are missing their healthy fiber, vitamins, and minerals. Refined grains quickly convert to sugar, which your body stores as fat. A diet high in refined grains can cause belly fat, which studies link to heart disease and type 2 diabetes
Answer:
a) B b) D c) A
Explanation:
Alleles exhibit dominance over each other leading to the dominant one being express and the recessive one not expressed. Alleles are variants (different) genes that codes for a specific trait.
At Anaphase 1 homologous chromosomes separate leading to each being pulled to the opposite pole and the sister chromatids remain together while the homologs experience segregation.
Dominant trait is the one that is expressed. It usually exercise dominance over recessive trait until it is removed from the recessive trait and replaced with another recessive gene before it is expressed.
Answer:
In a fair test two or more things are compared. In order for a test to be fair or scientifically sound, children are required to ensure only one thing (this is called a variable) is changed.
For example, if testing which material is the most waterproof by pouring liquid onto a selection of different materials, in a fair test only the type of material (the component you are testing) should be changed. Therefore all other elements (the type of liquid used, the amount of liquid used, the distance the liquid is poured from, the speed at which it is poured and the size of the material) must remain the same each time the test is carried out. It would be unfair or an unscientific test if, for example, 1000ml of water were poured onto a piece of foil and 2ml of milk poured onto a piece of foam – you would not be able to fairly compare the materials.

Convergent evolution is when 2 species not necessarily alike evolve similarly because of the same environment characteristics.
Adaptive radiation is when a species moves from mainland to another place and evolves there.
Answer. B ) Convergent evolution produces organisms with similar adaptations but different ancestry, whereas adaptive radiation produces organisms with different adaptations but common ancestry.
Answer:
Muscular dystrophy
Explanation:
Muscular dystrophy is an inheritable genetic condition that involves mutations in genes that encodes the production of muscle proteins to build and to preserve healthy proteins. The disease is characterised by progressive weakness and loss of muscle mass.
Dystrophy is referred to as a disorder in which the a tissue or an orgasm progressively wastes away. Thé dystrophy term is used because the disease involves the gradual and progressive wasting away of the muscle which is a type of tissue causing muscular weakness allowing the child to experience these symptoms.
