Gel nails typically grow out at the same rate as natural nails, which is about 1/8 inch per month. This means that gel nails can last for several weeks before needing to be filled or replaced. However, the exact rate of growth can vary from person to person based on factors such as genetics, diet, and overall health. Regular maintenance and proper care can help extend the life of gel nails and minimize the appearance of growth. **

The cage is not secure enough to keep out martens. Martens are known for their agility and ability to squeeze through small openings. To effectively keep martens out, the cage would need to have smaller gaps between the bars or be made of a material that martens cannot chew through. Additionally, adding a secure locking mechanism would also help prevent martens from gaining access to the cage. **

A blockchain is structured as a decentralized, distributed ledger that records transactions across a network of computers. Each block in the chain contains a list of transactions, a timestamp, and a reference to the previous block, creating a chronological and immutable record of all transactions. The network of computers, or nodes, work together to validate and add new blocks to the chain through a consensus mechanism, such as proof of work or proof of stake. This structure ensures that the blockchain is secure, transparent, and resistant to tampering or fraud. **

The question of whether cryptocurrency is considered haram, or forbidden in Islam, is a topic of debate among Islamic scholars. Some argue that cryptocurrency is haram due to its speculative nature, potential for fraud, and lack of intrinsic value.

Ultimately, the permissibility of cryptocurrency in Islam may depend on how it is acquired, used, and the specific circumstances surrounding its involvement. It is advisable for individuals to seek guidance from knowledgeable scholars to make an informed decision. **
