Root hairs are tubular outgrowths of root epidermal cells in plants. These outgrowths help plants absorb water and nutrients by increasing root surface area. Root hairs form when membrane-bound structures inside root epidermal cells carry macromolecules to one side of the cell. There, the structures fuse with the plasma membrane, releasing their contents outside the cell. The released macromolecules are then incorporated into the elongating cell wall of the root epidermal cell, which allows the root hair to continue growing.
A group of scientists discovered a plant that had no root hairs. The scientists determined that this phenotype was due to a genetic mutation that inhibited the process by which root hair growth takes place. This mutation was located in the rth1 gene.
Based on the information above, which of the following cell processes did the rth1 mutation most likely inhibit in the plant with no root hairs?
A. Facilitated diffusion through membrane channels
B. Vesicle fusion during exocytosis
C. Receptor-mediated endocytosis
D. Membrane transport mediated by transmembrane ATPases

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this

ans.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
