Answer:
The correct answer is option B. It bind to a receptor in the plasma membrane.
Explanation:
Hormones can be aminoacid based hormones (peptide or amine) or the steroid base hormones on the basis of their nature. Amino acid based proteins are molecules that are proteins,
Peptide hormones are the protein or peptide molecule that release in blood by the exocytosis in the form of preprohormones that mature later and bind to the receptor present on the surface of the plasma membrane of the target cell. The binding of the peptide hormone to the receptors a secondary messenger shows up in the cytoplasm.
Thus, the correct answer is option B. It binds to a receptor in the plasma membrane.
Answer:
A
Explanation:
because cell theory states that living things are composed of one or more cells, that the cells is the basic unit of life, and that cells arise from existing cells.
The answer is A. RNA polymerase will be making an mRNA using a single DNA strand as a template. So, for example if the DNA strand is AGGCAGC the mRNA strand will be UCCGUCG.
U= uracil which replaces thymine in mRNA molecules.

The answer is: B - Mitochondria
Explanation:
The mitochondria is the powerhouse of the cell.
The main function of the mitochondria is to provide energy for cellular activity by the process of aerobic respiration. In this process, glucose is broken down in the cell's cytoplasm to form pyruvic acid, which is transported into the mitochondrion.
Stereotactic radiosurgery (SRS) and immune checkpoint inhibitors (ICI) are increasingly used to treat brain metastases, however there is a paucity of prospective data on the effectiveness of these treatments in terms of cancer control.
Data from patients treated with SRS for non-small cell lung cancer (NSCLC) and melanoma brain metastases at a single facility from May 2008 to January 2017 were retrospectively examined. The impact of concurrent ICI within 30, 60, or 90 days of ICI administration on local control and remote in-brain control is examined using a parametric proportional hazard model. The regression model takes into account other patient and lesion characteristics as covariates and makes adjustments.
