4m/s²
Explanation:
Given parameters:
Velocity of the ride = 6m/s
radius of the ride = 9m
Unknown:
Acceleration of ride = ?
Solution:
We are going to solve this problem using the formula for centripetal acceleration:
Centripetal acceleration =
}{
}[/tex]
V is the velocity
r is the radius
Centripetal acceleration =
= 4m/s²

Answer:
You need to know how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
Physiological processes are limited to photosynthesis, cellular respiration, transpiration, and reproduction.
Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
Plant structures are limited to cambium, guard cells, phloem, seed, stomata and xylem.
Explanation:
Answer:
a. Genotype of the parents are; Rr and rr
b. Please find the explanation to A below
Explanation:
This question involves a single gene that codes for flower color in a plant. The allele for red flower (R) is dominant over the allele for white flower (r). This means that a plant that is heterozygous for flower color (Rr) will be red.
In a cross between a plant with red flowers and white flowers, the phenotype of the offsprings is represented as: 37 plants with red flowers and 41 plants with white flowers. Observing from this number, one would realize that the phenotype ratio is equivalent to 1:1. This phenotypic ratio is only possible when the parent with red flower is heterozygous for the gene i.e. Rr. Hence, the genotype of the parents are: Rr and rr.
b) If one were to cross Rr (red flower) × rr (white flower), the phenotypic ratio of red to white offsprings will be 1:1. Hence, judging from the ratio got from the cross of the two parents above (1:1), the parental genotypes are Rr and rr.
