6. In all vertebrate embryos, the process of gastrulation accomplishes the following important function(s):

a) Patterning the anterior-posterior axis (TRUE/FALSE)

b) Bringing mesodermal cells into the interior of the embryo (TRUE/FALSE)

c) Bringing ectodermal cells into the interior of the embryo (TRUE/FALSE)

Expert Solution

The gastrulation of the vertebrate embryo is a significent phse because the three germ cell layer Endoderm,Ectoderm & Mesoderm got separated and arranged in this phase which further develops and give rise to the body parts.

a) In Gastrulation when the cells differentiate and forms the neuronal tube it brings out the pattern of the anterior and posterior axis,specific gene (Hox) plays an important role in this type of pattern formation.

So this option is-TRUE.

b) The Grastrulation phase is important for differentiation and adjustment of the layers in specific position so that they can form the body parts. The Mesoderm layer forms tissue like the muscle,bone and connective tissue,this Mesoderm layer adjusted in the interior of the embryo.

So this option is-TRUE.

c) The ectoderm layer is the outermost layer,it forms tissue like- skin,hair,nail,neuron,pigment cells etc.

So this option is-FALSE

You perform the following experiment: Xenopus embryos are treated early in development (before gastrulation begins) with morpholinos to reduce the activity of Cerberus. You take an explant from the dorsal blastopore lip from a normal embryo at the beginning of gastrulation cell movements and inject it into the blastocoel of a normal host embryo. You then take a dorsal blastopore lip explant from a Cerberus 'morphant' (morpholino injected) embryo and transfer it into the blastocoel of a normal host embryo....

Some process has the following transfer function: Gp(s)= (s+8)/[(s+3)(s+6)(s+10)] We need to conrol this process very accurately so we add negative feedback and a controller. Design a suitable controller to meet the following specifications: Maximusm Overshoot is approximately 20% Settling time is 0.8s or smaller Steady-State error for a step input is zero

Which of the following characterizes the function of the vertebrate nerve cell and/or nervous system? a) They react to a stimulus. b) They produce impulses which cause the release neurotransmitters to stimulate other nerve cells. c) They generate motor output (movement). d) They regulate other cells. e) All of these are characteristics of the nerve cell and/or nervous system. In the Vertebrates the myocytes specialize to form: a) the Cardiac muscle cells, b) the spinal cord, c) the epithelial cells...

Consider a system with the following transfer function, G(s) = 10/ [s(s + 1)]. Design a compensator according to the following design objectives: • Kv = 20 sec−1 ; • PM = 50 oF; • GM ≥ 10 dB. Submit your answer regarding the detailed compensator design procedures, and the corresponding MATLAB code and figures to verify your design. In addition, compare the step response of both uncompensated and compensated systems in MATLAB
