Answer:
The correct answer is -
Actin produces thin contractile filaments within muscle cells,
Myosin produces the dense contractile filaments within muscle cells
Explanation:
Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.
Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.
Answer:
Ultimately what makes each cell different despite the fact that they share the same set of DNA is regulation of gene expression, which regulates the expression of genes. In other words, it determines which genes are turned off and which are turned on in a cell. Gene expression can be regulated in many ways; it's mainly centered around molecules like transcription factors that have the ability to turn certain genes on and off and activators, which promote transcription of DNA.
The short answer to this question is cell differentiation. Differential gene expression results from the genes being regulated differently in each cell type, and differential gene expression leads to different cells.
In fact, from the very beginning of our lives, so to speak, when we're developing from a zygote into an embryo, the egg that makes up the zygote in fact already has a sequential program of gene regulation tat is carried out as cells divide, and this program makes the cell become different from each other in a coordinated fashion.
I believe the answer you're looking for is photosynthesis, where plants release oxygen and humans use this to release carbon dioxide to the plants.
Arterial blood pressure is the volume of the blood entering the arteries, or veins. It's controlled by the kidney and when there's too much liquid, it rises, and when there's too little liquid, it drops. Sorry if this doesn't help, but I hope it does.
