Answer:
Temperatura optimă de germinare este cuprinsă intre: 22-26oC. Temperatura de germinare nu trebuie să fie mai mică de 15oC.
Umiditatea de 100%
Lipsa completă a luminii în primele zile până la răsărire (acoperire cu ziare sau carton din hârtie).
The flu vaccine changes every year. The flu vaccine is based on a predicted strain that is anticipated to be the most infectious that year. Thats why people who sometimes get the vaccination still get the flu, they don't have the antibodies for the strain they were infected with. Strains for viral disease don't change very much and usually the vaccination for them cover them well.

Explanation:
Each chromosome represents a twin.like pairs of socks.
This is an analogous problem: you have 2 pairs of socks, one white, one black. Each of the sock is tailored to a specic foot, right or left. How many different ways can the socks be mixed and matched , one for each foot?
Here are the possibilities : left = black, right = black is one such match. Left = white, right = black is another.
so also we will have 23 chromosome pairs
No, the most healthiest and recommend way to deal with stress is by exercising. (For exp: walking, jogging, interaction, etc...)
Answer: Biological polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers. When small organic molecules are joined together, they can form giant molecules or polymers. These giant molecules are also called macromolecules. Natural polymers are used to build tissue and other components in living organisms.
Generally speaking, all macromolecules are produced from a small set of about 50 monomers. Different macromolecules vary because of the arrangement of these monomers. By varying the sequence, an incredibly large variety of macromolecules can be produced. While polymers are responsible for the molecular "uniqueness" of an organism, the common monomers are nearly universal.
The variation in the form of macromolecules is largely responsible for molecular diversity. Much of the variation that occurs both within an organism and among organisms can ultimately be traced to differences in macromolecules. Macromolecules can vary from cell to cell in the same organism, as well as from one species to the next.
