Number of protons in Uranium-235 is 92
Number of neutrons in Uranium- 235 is 143
Explanation:
Isotopes are the two or more elements having the same number of protons and electrons but different number of neutrons. They differ in their atomic masses.
Atosiban is a nonapeptide, desamino-oxytocin analogue, and a competitive vasopressin/oxytocin receptor antagonist (VOTra). Atosiban is indicated to delay imminent pre-term birth in pregnant adult women. Atosiban is useful in improving the pregnancy outcome of in vitro fertilization-embryo transfer (IVF-ET) in patients with repeated implantation failure (RIF). The pregnancy rate improved from zero to 43.7%.https://www.creative-peptides.com/product/atosiban-item-10-101-05-14.html
Answer:
b) Channel pumps
Explanation:
The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.
For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.
