Answer:
They contain protein fibres that can contract when energy is available, making the cells shorter.
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
Answer:
Tissue fluid consists of water, ions, and dissolved gases and food substances, which is formed when blood is ultrafiltered from the capillaries into the intercellular spaces. The tissue fluid surrounds the body cells, facilitating the exchange of nutrients and waste materials. It helps bring oxygen and nutrients to cells and to remove waste products from them. As new tissue fluid is made, it replaces older fluid, which drains towards lymph vessels.
Lymph is a colorless fluid containing white blood cells, which bathes the tissues and drains through the lymphatic system into the bloodstream. It is essentially tissue fluid that has entered a lymphatic capillary. Lymph formation depends upon tissue fluid formation.
Explanation:
The base pair rule of DNA and RNA is that A-U, G-C, T-A and C-G. So using this rule, we can easily get the answer is that UUG CGG CAG GCG AUC. Hope this helps.
