The true difference between the two cells is prokaryotes
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. On the other hand, Eukaryotes are organisms consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.
The correct answer is A. Breast
Explanation:
BRCA-1 that stands for Breast Cancer Type 1 Susceptibility Protein is a tumor suppressor gene and protein related to breast cancer. This means, BRCA-1 can stop cells from developing into cancer, although the function of this gene can change and even be suppressed and thus, cancer might develop due to this. BRCA-1 is located in chromosome 17 in humans and act in cells by repairing DNA or in some cases destroying it, which stop possible mutation that can lead to cancer. Due to this, it is believed by studying BRCA-1 and the correct function of it or possible mutation it might be possible to know the risk for breast cancer in individual as well as detecting first stages of Breast Cancer. Thus, BRCA-1 is mainly related to Breast Cancer.
An amino acid is the building block (or monomer) of proteins :)
Answer:
The answer is B- no muscle tension could be generated
Explanation:
During contraction cross bridges are formed by the myosin thick filaments grabbing on to the actin thin filaments. . The overlap of the thick and thin filaments allows myosin to bind to actin. As more bridges are formed, more myosin will pull on actin and more tension will be produced. Muscle tension is a condition in which the body remains semi-contracted for a longer time, it is caused when muscles contracts and do not release.
However, if the muscles are stretched to a point where the thick and thin filaments no longer overlap there will be no muscle tension generated.
Liquid forms drops because the liquid exhibits surface tension. ... The surface tension of the liquid causes the liquid to hang from the tube, forming a pendant. When the drop exceeds a certain size it is no longer stable and detaches itself. The falling liquid is also a drop held together by surface tension.
