Yuri [45]

Explanation:

We have a case of incomplete dominance (purple is an intermediate heterozygous phenotype in radishes)

Parental genotype => RR x WW

F1 genotypic ratio => RR:RW:WW = 1:2:1

F1 phenotypic ratio

=> Red : Purple : White = 1:2:1.

bogdanovich [222]

Answer: They will fall at the same time.

Explanation: This is a free fall equation. Free fall equations don't use other factors such as air resistance or wind.

Answer: 15m

Explanation:

Given: Vi = 10m/s

t = 1s

a = 10m/s/s

The equation you need to use is d = Vit + 0.5at^2

d = Vi t + 0.5 a t^2

d = (10 m/s) (1 s) + 0.5 (10 m/s^2) (1 s)^2

d = (10 m) + 0.5 (10 m/s^2) (1 s)^2

d = (10 m) + (5 m/s^2) (1 s)^2

d = (10 m) + (5 m/s^2) (1 s^2)

d = (10 m) + (5 m)

d = 15 m

Contrast fast fibers with slow fibers in terms of diameter, glycogen reserves, myoglobin content, and relative abundance of mito

GrogVix [38]

Answer:

The skeletal muscle fibres are of two types namely slow-twitch muscle fibres (type I muscle fibre) and fast-twitch muscle fibre (type II muscle fibre).

The slow fibres are slow contracting and help in developing endurance such as long distance running, maintaining posture etc whereas fast fibres are fast contracting and help in movements which require force such as sprinting etc.

Other differences are summarized in a tabular form attached below.
