Answer me.

I have alot of questions. But very little answers.

19, Tamil, Singaporean. Abit lost as to what I'm trying to achieve. I know I want to be a vet, and I'm prepared to do anything to get there. Just that my attitude doesn't cooperate with me sometimes. Okay, make that most of the time. I'm lazy, very lazy. I care about things, and I have brains. Guess that my complacency overrules everything.

7 reasons why cancer cells are immortal
1. Cancer cells don’t age.Normal cells go through senescence through shortening of telomeres with every cell division. Cancer cells however have telomerase that will sustain the telomere length of the chromosomes rendering the cell virtually immortal.2. Cancer cells have a way around apoptosis, their programmed cell death.They overexpress antiapoptotic molecules and can multiply forever.3. The Grim Reaper can’t recognize them.The Natural killer cells, or the Grim Reaper; are supposed to cause death of the tumor cells. However, cancer cells remain undetected because they down regulate their MHC proteins or use decoy proteins to look innocent.4. If recognized, the Grim Reaper can’t kill them.Tumor cells block the death receptor pathway and directly interfere with the perforin/granzyme pathway. That is why, natural killer cells fail to kill them.5. Cancer cells don’t need anything.Cancer cells are self sufficient on growth factors. This means that they can continue to proliferate and divide independently, as opposed to normal cells that need external growth factors.6. And if they do need something, they order it to come to them.When cancer cells need of oxygen and nutrients, they stimulate angiogenesis; which is inducing growth of new blood vessels.7. They have metabolic super powers.The metabolism of malignant cells is usually more anaerobic than that of normal cells and is greatly accelerated. Malignant cells have the ability to withstand hypoxic conditions. They have increased glucose and amino acid uptake. In addition, they have high levels of hexokinase increasing their glucose utilization.

7 reasons why cancer cells are immortal

1. Cancer cells don’t age.
Normal cells go through senescence through shortening of telomeres with every cell division. Cancer cells however have telomerase that will sustain the telomere length of the chromosomes rendering the cell virtually immortal.

2. Cancer cells have a way around apoptosis, their programmed cell death.
They overexpress antiapoptotic molecules and can multiply forever.

3. The Grim Reaper can’t recognize them.
The Natural killer cells, or the Grim Reaper; are supposed to cause death of the tumor cells. However, cancer cells remain undetected because they down regulate their MHC proteins or use decoy proteins to look innocent.

4. If recognized, the Grim Reaper can’t kill them.
Tumor cells block the death receptor pathway and directly interfere with the perforin/granzyme pathway. That is why, natural killer cells fail to kill them.

5. Cancer cells don’t need anything.
Cancer cells are self sufficient on growth factors. This means that they can continue to proliferate and divide independently, as opposed to normal cells that need external growth factors.

6. And if they do need something, they order it to come to them.
When cancer cells need of oxygen and nutrients, they stimulate angiogenesis; which is inducing growth of new blood vessels.

7. They have metabolic super powers.
The metabolism of malignant cells is usually more anaerobic than that of normal cells and is greatly accelerated. Malignant cells have the ability to withstand hypoxic conditions.

biomorphosis:

The maned wolf is the largest canine species in South America and closely resembles a red fox on stilts because of its long legs. It is neither a wolf, fox, coyote, or dog  but rather a member of its own Chrysocyon genus, making it a truly unique animal. They possess a mane that runs from the back of the head to the shoulders which can be erected to intimidate other animals when displaying aggression or when they feel threatened. 

Unlike other wolves that live in packs, maned wolves do not form or hunt in packs but prefer to live alone.  Maned wolf is considered as the last surviving species of the Pleistocene Extinction, which wiped out all other large canids from the continent.

A Morning With Your Little One
Waking up in the morning with your little one laying beside you is a beautiful way to start your day. To watch her still peacefully sleep, and admiring how cute and innocent she looks sleeping. Then when she opens her sleepy eyes, to pull her close. Just cuddling her close against your chest.
Cuddling her until she gets woken up while you gently rub her back, and lightly pat her bottom, and occasionally give her a little kiss. Then getting out of bed with her and taking her to the kitchen to cuddle on the couch eating breakfast together as she lays her legs on your legs and leans against you.

The only thing more shocking about the purple swamphen (Porphyrio porphyrio) than its plumage, is its diet. While it feeds mostly on vegetation, it is also known to eat the eggs and even the live young of other water birds. It is one of the largest members of the rail family (consisting of crakes, coots, and gallinules, among others), and its robust build allows it to more or less roam wherever it pleases within its range.
