Answer:
A. They have identical DNA in all of their cells.
Explanation:
Identical twins are also known as monozygotic twins. They result from the fertilization of a single egg that splits in two. Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy.
The protein involved in elongation of Bacillus Antrasis to form its typical shape is called FtsZ.
FtsZ is a GTpase that polymerises in nucleotide dependent manner head to tail to form a single stranded filaments that assemble into a contractible ring.
The correct answer is option D, that is, C30H52O26.
The majority of macromolecules are formed as single building blocks or subunits, known as monomers. The monomers attach to each other through covalent bonds to produce bigger molecules called polymers. In performing so, the monomers discharge molecules of water as byproducts. This kind of reaction is called dehydration synthesis.
In a dehydration synthesis reaction among the two un-ionized monomers, like monosaccharide sugars, the hydrogen of one monomer merges with the hydroxyl group of another monomer, discharging a water molecule in the process.
The withdrawal of a hydrogen from one monomer and the withdrawal of a hydroxyl from the other monomer permits the monomers to share electrons and produce a covalent bond. Therefore, the monomers, which are combined together are being dehydrated to permit for the production of a larger molecule.
Answer:
They became closer to each other.
Explanation:
When skeletal muscles contracts the Z lines that are at the end of every sarcomere became closer to each other due to the fact that the I bands that are attached to the Z lines and contains the myosin filaments move closer to each other interacting with the actin filaments and shorten the the H zone that is in the middle of the sarcomere. In other words, It all becomes compact during a contraction.
Answer:
The food we eat - our diet - is made up of different biological molecules which gives us energy and contain chemicals we need to grow and repair ourselves and help our cells function in our body.
Carbohydrates and fats are made up of carbon, hydrogen and oxygen.
Proteins contain carbon, hydrogen, oxygen and nitrogen.
