Kutip

Ada bukti riset menunjukkan bahwa radiasi UV ternyata punya potensi dapat " menggugah " status " tidur " HIV. Dengan " sentuhan " ( eksposur ) sinar UV dalam intensitas tertentu virus AIDS yang semula dalam kondisi laten " terbangun " menjadi reaktif. Tingkat reaktifitas bahkan mencapai puluhan sampai ratusan kali lebih kuat daripada tingkat reaktifitas normalnya, dalam arti tanpa faktor pemicu seperti radiasi UV. Informasi ini antara lain pernah diungkap dalam majalah ..........................

" virus " yang menjadi reaktif karena sentuhan sinar UV seperti disampaikan dalam kutipan di atas, apakah tergolong / termasuk ciri-ciri makhluk hidup ?

satu satunya alasan virus disebut mahluk hidup itu kan karena dia berkembang biak kan? Kalau bgt virus komputer apa bisa disebut mahluk hidup? dia kan berkembang biak (menggandakan diri)?

beda lah... emang virus komputer ada bentuk fisiknya?
jadi inget pas di awal 90-an. waktu itu komputer rumahan masi jarang. saya dan beberapa teman ngerjain tugas pake komputer salah satu rekan. trus ada temen yang bersin deket komputer. mama pemilik komputer langsung menasihati, 'eh, hati-hati, jangan bersin di depan komputer, nanti komputernya kena virus...' (bayangin aja ada komputer kena pilek!)

apa harus punya bentuk fisik?

Pencarian planet berpenghuni biasanya mengikuti "standar" bumi: ada air, ada udara, hangat, dll. Bagaimana kalau ada alternatif kehidupan bentuk lain, misalnya mahluk hidup berbentuk gas atau apa?

bentuknya kayak ranjau jangkar ............

kalo ada yang belum tahu ranjau jangkar, yaitu seperti virus yang menyebabkan hari ini 1 Desember menjadi hari peringatan seluruh dunia

ranjau jangkar diameternya kurang lebih 1 meter, kalo virus itu diameternya kurang lebih 200 nm .................

makhluk hidup bentuk gas? sepertinya susah karena gas susah mempertahankan wujudnya, kena angin dikit aja udah berantakan. selain itu diperlukan air sebagai media reaksi metabolisme. makhluk hidup yang saat ini diketahui nyaris sedikit komponen padatnya adalah ubur-ubur. kadar air mereka bisa mencapai 95%.

The Seven Characteristics of Living Things

Feeding

All living organisms need to take substances from their environment to obtain energy, to grow and to stay healthy.

Movement

All living organisms show movement of one kind or another. All living organisms have internal movement, which means that they have the ability of moving substances from one part of their body to another. Some living organisms show external movement as well - they can move from place to place by walking, flying or swimming.

Breathing or Respiration

All living things exchange gases with their environment. Animals take in oxygen and breathe out carbon dioxide.

Excretion

Excretion is the removal of waste from the body. If this waste was allowed to remain in the body it could be poisonous. Humans produce a liquid waste called urine. We also excrete waste when we breathe out. All living things need to remove waste from their bodies.

Growth

When living things feed they gain energy. Some of this energy is used in growth. Living things become larger and more complicated as they grow.

Sensitivity

Living things react to changes around them. We react to touch, light, heat, cold and sound, as do other living things.

Reproduction

All living things produce young. Humans make babies, cats produce kittens and pigeons lay eggs. Plants also reproduce. Many make seeds which can germinate and grow into new plants.

Apakah yang dimaksud adalah "consciousness"? Jika ya, bagaimana cara mengukur secara kualitatif maupun kuantitatif consciousness itu? Saya lebih setuju bahwa uraian Prof Houw Liong berikut lebih bisa dipertanggungjawabkan secara ilmiah:

Biobio:
Robot pun nantinya bisa demikian, tapi tetap saja bukan benda hidup. Malah boleh jadi tanaman adalah benda hidup yang punya kesadaran, maksudnya, bisa merasakan ini dan itu.

Keduluan pak THL postingnya .............

Post di atas yang tadinya ingin saya usulkan agar dikukuhkan penyebutannya menjadi salah satu Hukum dalam Biologi, mencontoh di Fisika itu kan banyak hukum2nya ..................

Misalnya disebut : Hukum Pertama Biologi.
