The vascular system of the plants are responsible for transporting water and needed nutrients for the plant to survive. Hence, when this is disturb certain transpirational pull is also disrupted, rendering the plant unable to collect water effectively. Thank you for your question. Please don't hesitate to ask in Brainly your queries.
Answer:
1. tall (or heterozygous)
2. 3:1
3. carriers
4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.
5. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.
6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.
7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.
Explanation:
Answer:
F1 Generation -
Genotype - GgRr
Phenotype - Green and round
F2 generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled
9: 3:3:1
Explanation:
G represents Green seed color
g represents yellow seed color
R represents round seed
r represents wrinkled seed
Here G is dominant over g and R is dominant over r
F1 generation -
Genotype of true breeding parents will be
GGRR and ggrr
The offspring produced will be -
GgRr
Genotype - GgRr
Phenotype - Green and round
F2 Generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled

Answer:
The correct answer is A acetylcholine binds to a receptor protein on the motor end plate
Explanation:
The neurotransmitter acetylcholine is released by the motor neuron during the transmission of signals across a neuromuscular junction.
The released acetylcholine then diffuses the synaptic cleft and binds to the receptor protein present on the membrane of muscle fibre.
This ultimately result in the influx of sodium ion inside the muscle cell thereby causing depolarization to generate an action potential.
<span>Jeremy has change in his moods ad wanted to smoke than usual in addition to Parkinson disease, this may be because his brain is producing less acetylcholine than it suppose to. This is the reason he is lacking certain planning and control of actions and is disoriented.</span>
