Answer: Sister chromatids.
Explanation: Because the Sister chromatids carry the same alleles.
Answer:
Through natural selection, organisms carrying better traits to survive in an ecosystem are able to survive and pass on their characteristics to their offspring. Through evolution, the allelic frequency of the population changes in abundance of the traits which are favoured by natural selection. As the male pom-pom monkeys carrying long bright puffs of turquoise fur all around his neck had a better adaptation to survive on the island hence, they were favoured by natural selection and through evolution all long bright puffs of turquoise fur all around his neck evolved.
Muscles have their origins (also known as heads) and insertions. Those are places where the muscles are anchored.
A word biceps is made of two Latin words: bi - two and ceps - head. So, biceps is two-headed muscles. It has two origins: coracoid process of the scapula and supraglenoid tubercle.
Similarly, a word triceps is made of three Latin words: tri - three and ceps - head. So, triceps is three-headed muscles. It has three origins: infraglenoid tubercle of scapula, above the radial sulcus, and below the radial sulcus.

Answer:
New discoveries in the treatment of cancer do not only centre on conventional medicine. In our haste to get to grips with a cure for cancer, natural products may be overlooked and dismissed in the fight against such an aggressive disease.
In December, the Academy of General Dentistry reported that a new study had found that simply swishing green tea around the mouth halts the growth of new oral cancer cells and breaks down and kills existing oral cancer cells. The antioxidants (polyphenols) in the tea work to remove the free radicals or oxidants and prevent gene mutations, and as an added bonus, the polyphenols can kill cancerous cells without harming normal cells and inhibiting their growth. Similarly, a chemical found in tomatoes may prevent or treat oral cancer and one derived from soybeans has been found to shrink abnormal growths that lead to cancer. While these are not cures, their activity may in the future lead to therapies that compliment conventional treatment modalities.
Perhaps combining ancient remedies with Western scientific advances is the way forward to finding an effective cure for cancer. Combrestatin – a cancer-fighting drug made from the bark of an African tree – is performing with dramatic effects in tests. The active ingredient extracted from the bark attacks the blood vessels that grow with tumors, while leaving normal blood vessels alone.
