A temperature inversion is a thin layer of the atmosphere where the normal decrease in temperature with height switches to the temperature increasing with height. An inversion acts like a lid, keeping normal convective overturning of the atmosphere from penetrating through the inversion.
Answer:
SIMPLE DIFFUSION transport
Explanation:
According to this question, John could smell the fragrance of his newly bought bottle of cologne all the way up the hall before he can even get into his bedroom, where he usually keeps it. However, he realizes when he got to his bedroom that he left the bottle of cologne uncovered.
The fragrance of the cologne that spreads from the bedroom all through the hall is as a result of SIMPLE DIFFUSION, a form of PASSIVE TRANSPORT. Diffusion is a form of passive transport in which molecules/fluids move from a region of high concentration to a region of low concentration until it is evenly spread. This is the case with John's cologne, which spread from the bedroom where the concentration is high to the hall, where it is low.
Answer:
The two blue budgies are most likely to be yyBb each
Explanation:
there are 3 different scenarios possible for crossing blue budgies:
1) yyBB crossed with yyBB
this is not possible because it does not allow for the genotype yybb (white budgies)
2) yyBB crossed with yyBb
again, this cross will not yield the genotype yybb required for white budgies as given in the problem statement
3) yyBb crossed with yyBb
which leaves us with this option being most likely the genotype of the parent budgies who will have white budgies as offspring
Hope that answers the question, have a great day!
Here I provide you some examples of modified stems:
<u>Bulb:</u> discoid stems that have a single apical bud surrounded by numerous cataphiles, and in their part I have adventitious roots. Its function is the reserve.
<u>Tuber</u>: They are portions of stems with irregular growth, which forms tuberosities due to the large accumulation of reserve substances.
<u>Cladodes: </u>are flattened stems, very thick, green leaves look alike and have photosynthetic function.
<u>Stem tendrils:</u> they are filamentous stems, which can be rolled up so that the plant can climb grasped of various objects, which is useful when the plant needs to look for the greatest possible luminosity, especially in areas where shadows predominate.
Phylloclades: Stems sheet form with limited growth, like a leaf, green and photosynthetic color.
Answer:
They transcribe RNA to DNA using reverse transcriptase.
Explanation:
<u>Retrovirus</u>
A type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV, the virus that causes AIDS, is a retrovirus.
Retroviruses have an enzyme, called reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell.
