Answer:
1500
Explanation:
Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.
The total population size of F2 generation = 2000
The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)
Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500
The mesosphere is the coldest layer of the atmosphere.
Hope that helped you.
The stimuli plants respond to will be found in the environment. Example....plants grow towars the sun.
TRUE !
there are rain forests in Oregon & other places near buy. Also, just wanted to let you know, don’t come for my head if this answer is incorrect.
KINDEST REGARDS !
Answer:
Maintenance of postural equilibrium is an integrated process requiring optimal muscular balance, joint dynamics, and neuromuscular efficiency using visual, vestibular, and proprioceptive inputs.
Explanation:
Maintaining postural equilibrium involves multiple parts of the body, and can be divided in two levels of control: the first one being on the brainstem, the cerebellum and the spinal cord; and the second one including cortical areas that participate in multisensory integration and control as well as the basal ganglia located in the cerebrum.
