Animal viruses need a living host animal to survive, so this is why eggs are often used to grow them. It was show that the flu virus could be grown that way in 1931.
In clinical virology the use of embryonated eggs are frequently used because viruses need something living for the viruses characteristics to come out. It is frowned upon to use monkey and rats for this during school so embryonated eggs are the next best things.
Yes, flies can come from dead animals. When an animal dies, flies are attracted to the decaying flesh and lay their eggs on it. The eggs hatch into larvae (maggots) that feed on the decaying tissue, eventually developing into adult flies.
Fertilized eggs are eggs that have been fertilized by sperm, while embryonated eggs are fertilized eggs that have developed into embryos. In embryonated eggs, the embryo has started to grow and develop, while fertilized eggs are simply eggs that have been successfully fertilized.
Most chicks grow up and start laying eggs at about 20 week (5 months). This will vary by a week or two and the first eggs will usually be small and intermittent. Proper nutrition and husbandry (animal care) play a big role in this also.
Yes , it grows .
Chicken eggs are used as the medium to grow the viruses that are used in the preparation of the vaccine.
You don't. They grow from eggs laid by female bot flies under the skin of an animal. When the eggs hatch maggots grow under the skin and then metamorphose into adult bot flies, which then cut their way out to emerge through the skin.
They do indeed, like all birds. Theirs just happen to be about as big as they get. yes they do lay eggs but the eggs then hatch making the ostrich grow into a full bird. I love ostriches so i should know this.
Depends on the animal, but in general male produces sperm, female produces eggs, and MAY hold fertilized eggs until they grow (but not always)
Viruses require living cells to replicate and grow. Milk does not contain living cells, so viruses cannot infect or reproduce in milk. Additionally, milk has natural defense mechanisms, such as enzymes and antibodies, that can inhibit the growth of viruses.
Interferon
they grow in the mitosis
Eggs on plant leaves are often laid by insects as a way to protect and provide food for their offspring. The eggs can hatch into larvae that feed on the plant, helping the insect offspring grow and develop.
no. . . Because parasites and viruses can only grow on living matters... There may be saprophytes and bacteria growing in your food. . . Even parasites and viruses can be there but can not grow. .
Viruses are typically grown in living cells, such as bacteria or animal cells, as they need a host to replicate. Specialized growth media, such as culture medium or cell culture media, are used to provide the necessary nutrients for the cells and viruses to grow. These growth media are usually supplemented with amino acids, sugars, salts, and vitamins to support viral replication.
the eggs will grow until they are big full grow frogs!
Geckos come from eggs. Geckos come from eggs.
