Answer:
It happens in the diastolic phase of the cardiac cycle
Explanation:
During the diastolic phase of the cardiac cycle, blood is allowed to enter the heart when it relaxes after a contraction.
Approximately one systole (contraction phase) that lasts 300 milliseconds and a diastole of 500 milliseconds.
Photoreceptors convert light into signals that will be sent to your brain.
The are located in the inner part of the eye.
Answer:
Hello, congratulations on your observation! Let me explain.
Yeasts are unicellular eukaryotic organisms. This implies that: they reproduce easily and quickly, they have all the characteristics of a eukaryotic model and their maintenance is really simple and economical (once their cultivation has been developed).
While it is true that they present differences with other eukaryotes, such as patterns of glycation and dependence and / or exclusivity of some substrates, but even if they are a cell model easy to use in the early stages of research, for example in cancer. It allows a first approach of the metabolic and cellular machineries that take place in our cells. Later in the development of experiments, it may be necessary to use another study model, such as the mouse, rat or pig.
Answer:
You can modify the by adding specific ligands
Explanation:
Liposomes are vesicules that result from the self-assembly of phospholipids in an aqueous medium, they resemble cellular membranes and can have single or multiple concentric bilayers. They are really useful for drug delivery because it is a biocompatible system, it can transport hydrophilic and hydrophobic molecules and <em>they can be modified with specific ligands in order to reach their target, these ligands can be antibodies, peptides/proteins, and carbohydrates depending on the target.</em>
I hope you find this information useful and interesting! Good luck!
