In what way is surface area more important for cells than volume?

Virty [35]

Answer:

As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.

PLease Help 2. Instantaneous speed is the rate of motion of an object at a particular moment in time. What change(s) to the expe

yKpoI14uk [10]

To gather data on instantaneous speed via experiment, we can use limits i.e. using limits in the formula for example 1 second and 2 second interval with particular difference of distance traveled by object during this interval. for example if distance traveled after 2 second is 60m and after one second is 35m, then the speed will be the ratio of differences of distances and time intervals.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po

kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1
