<h2>Regional specialization of Human Nervous System</h2>
Explanation:
The statements that illustrate the regional specialization of human nervous system are-
a. Sensory information may be processed in the occipital lobe or the temporal lobe.
c. Reading a printed word out loud and then thinking of a related word involves the visual cortex, Broca’s area, and the frontal and temporal lobes.
Humans have the most developed nervous system among all the living organisms. Various parts of the nervous system has been specialized for various function. The human brain has been divided into different parts like cerebellum, cerebrum , medulla oblongata etc which are further divided into specialized parts. Each part is specialized to carry out particular function. Moreover, the nervous system has different types of neurons like motor neuron, sensory neurons and interneurons. Each type of neuron has specialized function.
Answer:
carbondioxide last in about 300 to a 1000 years in the atmosphere
Cell membrane would be corr3eect
Answer/ Explanation:
a. The genotype of a homozygous white eyed long winged female would be Vg+Vg+XrXr. We denote the white allele as recessive (r) because the XY male only has one copy and yet has red eyes, so the red eye trait (R) must be dominant. A homozygous red eyed vestigial winged male would have be VgVgXRY. The possible gametes for the female are Vg+Xr only. For the male, the possible gametes are VgXR or VgY
The attached punnett square shows the results of the cross. The females will all be Vg+VgXRXr. The males will all be Vg+VgXRY (must inherit Y from father). That means they will all have normal length wings, the males will have white eyes and the females will have red eyes.
b. The F2 flies arise from intercrossing the F1, so the cross will be Vg+VgXRXr x Vg+VgXRY. The possible gametes for the mother are: Vg+XR, Vg+Xr, VgXR or VgXr. The possible gametes for the father are Vg+Xr
, Vg+Y
, VgXr
, VgY
. The attached punnet square shows this cross. The ratio of the phenotypes will be 6:6:2:2, or 3:3:1:1 (long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye), genotypes shown in the attachment.
c. F1 cross back to the mother would be Vg+VgXRY x Vg+Vg+XrXr. The genotypes are shown in the attached punnet square. The offspring will all be long-winged with white eyes. The F1 to the father would be Vg+VgXRXr x VgVgXRY. The ratio would be 3:3:1:1 long-winged red eye: long-winged white eye: vestigial wing red eye: vestigial wing white eye
Genetic engineering is the direct manipulation of a specific gene. I would use it in this scenario
