Answer:
This question lacks options, the options are:
A. All 270 tall plants were heterozygous
B. All 270 tall plants were homzygous.
C. Only 90 plants were homzygous.
D. All dwarf plants were homzygous.
The answer is D.
Explanation:
This question involves a single gene coding for height in pea plants. The allele for tallness (T) is dominant over that of dwarfness (t). This means that a dwarf plant can only be homzygous recessive (tt) while a tall plant can either be homzygous (TT) or heterozygous (Tt).
According to the question, two tall heterozygous pea plants were crossed i.e. Tt × Tt. Based on this cross, a phenotypic ratio of 3:1 is expected, which is in accordance with the 270 tall plants and 90 dwarf plants (360 total) that was obtained in the cross. Since dwarfism in pea plants is a recessive trait, this means that all the dwarf plants produced in this cross (90) were homzygous (tt).
Explanation:
It stretched or compresses the sound waves it is producing if it is relatively moving away to getting closer respectively. This is called the <u>Doppler shift effect</u>..
This is why when a wailing ambulance approached you, the pitch of its wailing is high but when it passes you and moves away from you the pitch of the wailing lowers. Remember this is happening relative to your position.
<h2>
Answer</h2>
The right option is (A).
<h2>
Explanation</h2>
The RNA gets its information from DNA to synthesise the proteins. It is different from DNA also due to the difference in one nitrogen basis as uracil. The thymine, the nitrogen basis that is only present in DNA is replaced with uracil to form RNA coding. The uracil also contains the same features as thymine has in DNA strains. Uracil makes a double H-bond with the adenine but does not contain CH4 group which is present in thymine.
