Answer:
Special properties of an oxygen-binding protein in the muscles of marine mammals, such as seals, whales and dolphins, are the reason these animals can hold their breath underwater for long periods of time, according to a new study. ... In fact, the amount was so high in the muscle that it almost looked black in color.
Explanation:
Answer: the answer is option A. 5 → 1 → 6 → 3 → 2 → 4
Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol, SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses, SRP binds to its receptor, Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
Answer:
Tissue
Explanation:
A cell is a structure formed during the evolution which contained all the molecules and favourable conditions required to survive and therefore acts as the functional and structural unit of life.
In evolution, more than one cell aggregated together to form a structure which could perform much complex function than a single cell called tissue as they are programmed to perform the same function.
In the given question, since the heart cells worked together to cause movement in the robot therefore the cardiac cells formed cardiac tissue or heart.
Thus, the tissue is the correct answer.
Diffusion has a major part in this. It has proteins embedded in it that allow molecules to diffuse in and out of the cell up and down its concentration gradient.
