In aquatic plants, water passes among the tissues and provides the medium for gas exchange. In terrestrial plants, air enters the tissues, and the gases diffuse into the moisture bathing the internal cells.

<u>Answer:</u>
CCGAGU
<u>Explanation:</u>
DNA transcription:
DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.
During transcription two strands of DNA are named differently i.e Template strand and coding strand.
Template strand:
Strand from which RNA is producing is known as template strand while
Coding strand:
The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.
Correct Answer:
Template strand from 5' to 3' reads GGCTCA. and
In this question CCGAGT is coding strand.
RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
CCGAGU
Directional selection favors one of the extreme phenotypes. Option B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.
<h3>What is directional selection?</h3>
Directional selection increases in the proportion of individuals with an extreme phenotypic trait.
There must be a selective pressure or environmental pressure acting on populations to lead the species to increase the number of individuals expressing that extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example the environmental pressure is drought during several years.
Drought periods decreases the fitness of plants that produce thin seed coats because they dehydrate before germinating.
Originally the population expressed both types of seeds. But after the drought pressure, only plants that produce seeds with thicker coats got to survive and reproduce.
The correct option is B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.

your answer is C. cleavage, fracture
cleavage the way minerals breaks apart, split easily along a flat surface,
fracture the way minerals break apart, breaks in an irregular way
Answer:
a. Determine the allele frequencies of:
- f(T) = 0.485 ≅ 0.48
-
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation
-
F (TT) = 0.21
- F (Tt) = 0.55
- F (tt) = 0.24
the genotype frequencies of the next generation
-
F(TT) = 0.23
- F(Tt) = 0.5
- F(tt) = 0.27
