Answer: Muscles cell contain myosin II, which is responsible for muscle contractions.
Explanation:
Myosin are motor proteins that are responsible for muscle contractions and motility processes in animals.
Myosin II is also called conventional myosin is a form of myosin found in muscles cells and are responsible for muscles contraction in animal cells. It is found in non muscles cells called stress fibers.
Answer: Two molecules of H2A
Explanation:
Structural organization of nucleosomes were determined by isolating them from unfolded chromatin and it has been found that the basic units of chromatin are the nucleosomes which consist of histone octamers of two molecule each of histone H2A and other histone molecules like H2B, H3 and H4. The histones are wrapped around with 147bp of DNA in almost two (2) turns.
The correct answer is A) Salt is pulled apart into two ions by the polar water molecules, and sand is not.
This happens because salt has both positive and negative ends that are attracted by the polar molecules of water.
Answer:
3/16
Explanation:
Assuming that green, smooth peas are the dominant trait, as long as the gene has a dominant allele for colour or texture of the peas, the peas will be green or smooth respectively.
Hence wrinkled and yellow are the recessive traits. That must have a combination of 2 recessive alleles in the gene to have the recessive trait.
Assuming G is the allele for green and g is the allele coding for yellow peas, and W represents allele for smooth skin and w represents wrinkled skin,
The probability of 2 heterozygote parents (green and smooth) crossing with genotype of GgWw and GgWw to get offspring with Green and wrinkled peas of genotype G_ww (whereby _ represents either G or g), is 3/16 refer to diagram above.
The human body is consist of cells. It means that cells are everywhere in our body. There are heart cells, lung cells, brain cells, etc. Even our finger nails are mainly cells. They become of all the important organs and parts in our body. Imagine your heart, lung, or brain is functioning not well or making you feel pain because something goes wrong with those related cells? Not even to think about it. The human body can’t live without the good functions of cells.
And to be more concise, proteins are the major part of cells. Where there is a cell, there is a protein or more. Learn more about proteins in human body, visit www.creativebiomart.net/research-area.htm for professional knowledge. It’s a protein supplier who could be reliable on proteins based on their large amount of lab data.
Wish this would help.
