Cho 2 nòi ruồi giấm thuần chủng: ruồi mắt đỏ cánh dài với rìu mắt nâu cánh ngắn ở F1 thu được ruồi mắt đỏ cánh dài -có thể rút ra được kết luận gì về sự di truyền của những tính trạng nói trên ?

-nếu đem lai phân tích rùi đực F1 nói trên ta thu được kết quả như sau: 587 con mắt đỏ cánh dày : 567 con mắt nâu cánh ngắn từ kết quả trên rút ra được kết luận gì về sự di chuyền của các tính trạng trên? Viết sơ đồ lai

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
