Answer:
Horsetails vary in appearance, but they all lack leaves and have no close relatives. The most similar group of plants are the ferns. They use both their branches and their stems for photosynthesis, as opposed to having foliage. The stalks of the horsetails are almost hollow in the center.
Explanation:
Dominant allele for height T
Recessive allele t
Genotypes for tall Tt or TT
Genotype for short tt.
If there is 8,216 plants, 3,122 are short, which means that 5094 are tall.
Frequency of the recessive homozygous is q2 and it is 3122/8216=0.38, which means that only q=0.62
If p+q=1 (HW equilibrium), than p=0.38
Frequency of dominant homozygous is p2=0.14
The number of dominant homozygous is 0.14*8216=1183
The number of heterozygous is 5094-1183=3911
The number of recessive homozygous is 3122
Astronomy. Astronomy coomes from the latin word for star and in ancient times "the stars" refered to anything in outer space.
Answer:
4. Transition metals
Explanation:
Transition metals differ from the other elements because their valence electrons can be found in more than one shell, specifically, in the last two shells. Another notable difference between transition metals and other elements on the periodic table is that they can have more than 8 electrons in their outermost shell. They can have up to 32 electrons.
Answer:
Because your not close enough to get the virus if you have a mask, but if you don’t wear a mask, social distance is irrelevant because the sneeze or cough travels more that 100 feet and then your caught with the virus.
