Which atom is involved in giving your heart energy to beat?

Biology

Answer:

Oxygen

Explanation:

The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

Juliette [100K]

Answer: Both the mouse and human beings are encoding the proteins having similar functions.

Explanation:

The CFTR gene in the mouse and CFTR gene in the human beings encode proteins that perform similar function,this is so because if the results are same then it means that both mouse and human beings are encoding the protein that have similar function.

Option A is incorrect  because both humans and mouse are eukaryotes so they have introns and because of that even if the gene sequences are different they can still encode protein.

Option B is incorrect because  amino acid sequences can be similar inorder to have the similar function. If glutamic acid is replaced by aspartic acid, it won't have different function the function will remain same. So, identical amino acid sequences are not required. They can be similar too.

How does Thermally Sensitive Liposomes Work?
Virty [35]

Answer:

Thermosensitive liposomes (TSL) are promising tools used to deliver drugs to targeted region when local hyperthermia is applied (∼40–42°C) which triggers the membrane phase transformation from a solid gel-like state to a highly permeable liquid state. Selective lipid components have been used to in TSL formulations to increase plasma stability before hyperthermia and speed drug release rate after. Two generations of TSL technology have been developed. The traditional thermal sensitive liposomes (TTSL) have utilized DPPC and DSPC as a combination. The second generation, lysolipid thermally sensitive liposomes (LTSL) technology, has been developed with incorporation of lysolipids that form stabilized defects at phase transition temperature. LTSL maintains certain favorable attributes:

High percentage of lysolipids incorporation;

Minimum leakage for therapeutical drugs encapsulation;

Ultrafast drug release upon heating (3.5 times enhanced compared to TTSL). For example, ThermoDox, a commonly used LTSL drug for cancer, has been reported to release 100% of the encapsulated doxorubicin within 30s;

First and most successful formulation for intravascular drug release.
