Answer:
Root hair cells
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption

Explanation:
Answer:
The right answer to the concept whereby sound waves undergo constructive intereference to producing a louder sound in musical instrument would be superimposition.
Explanation:
When sound waves are produced, especially from a musical instrument, numerous beats are produced, which have different frequencies. The sound waves mix with each other in any of Destructive or constructive interference. When the waves are moving in the opposite direction with the same amplitude, they tend to cancel out each other to produce a quieter sound wave. The constructive interference of sound waves results in a wave with an accumulated amplitude of individual waves, thereby producing a louder sound wave. When sound waves are in combination into a higher amplitude is called superimposition.
Since, the experiment is not given but on the basis of the mechanism of genetic transfer this question can be answered.
Answer:
The mechanism of gene transfer is important and beneficial for bacteria in the adverse environment conditions. The different mechanism of gene transfer are conjugation, transformation and transduction.
The ampicillin resistance gene is present on the plasmid DNA and not on the chromosomal DNA. Only conjugation is the mechanism in which the plasmid DNA is transferred from one bacteria to another bacteria. The ampicillin resistance gene is transferred from Strain II to strain I means from the bacteria that has the ampicillin resistance gene to the bacteria that has no ampicillin resistance gene in it.
Answer:
They produce seeds which are encased by an outer layer such as fruit.
Answer:
C) 91%
Explanation:
First,
Express the Dominant phenotype as homozygous dominant(BB) and heterozygous(Bb).
Based on hardy-Weinberg equilibrium,
homozygous dominant (BB) Brown eye individuals will have the following percentage
B × B
(Where B = 70%)
70% × 70%
= 49%
heterozygous dominant (Bb) Brown eye individuals will have the following percentage
Using 2 × B × b (where B =70% and b = 30%)
2 × 70% × 30%
= 42%
The proportion of the subsequent generation with brown eyes
(homozygous dominant, BB + heterozygous dominant, Bb)
= 49% + 42%
= 91%
