Answer:
a. Her mother has zig-zag antennae.
b. Her brother has zig-zag antennae.
Explanation:
<u>Available data</u>:
- Antennae development ⇒ controlled by maternal effect
- Zig-zag coils are dominant
- Curly coils are recessive
- A female develops zig-zag coils
Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. Even though the progeny has a different genotype, it is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. The maternal effect is commonly seen in insects and might be seen in some mammals and plants.
So, if a female has zig-zag coils, this means that the mother also has zig-zag antennae and that all the brothers and sisters of this female ant have zig-zag antennae, independently of their genotype.
a. Her mother has zig-zag antennae ⇒ True. The trait is inherited from the mother.
b. Her brother has zig-zag antennae ⇒ True. The whole progeny will express sig-zag antennae.
c. This female carries the zig-zag allele ⇒ Not necessarily.
d. This female's offspring will have zig-zag antennae ⇒ Depends on it´s genotype
Answer:
The correct answer is quadriplegia.
Explanation:
The paralysis of both the legs and arms has been known as quadriplegia. The main reason for quadriplegia is the injury to the spinal cord, however, other conditions like strokes and cerebral palsy can also result in similar paralysis. The degree of damage depends upon the part of the spinal cord injured and the amount of destruction done.
With the injury to the spinal cord, the brain loses the tendency to communicate with it and so the movement and sensation get impaired. Quadriplegia takes place when the region of the neck of the spinal cord gets injured like a C3 fracture. An extreme spinal cord injury may obstruct the process of breathing and hampers the movement of limbs.
An individual with complete quadriplegia loses the tendency to move any part of the body underneath the neck, even some are not able to move their neck.
The repeating stages a cell experiences, including cell division, compose the cell cycle.
Life cycle of the cell (cell cycle) can be divided in interphase and mitotic phase.
Interphase can be subdivided into:
• G1 phase characterized by the growth of the cell
• S where DNA replication occur
• G2 phase final preparation for mitosis.
Mitotic or M phase consists of:
• Prophase-condensation of chromosomes and mitotic spindle formation
• Metaphase-alignment of the chromosomes
• Anaphase- Sister chromatids are pulled apart by the mitotic spindle
• Telophase-each pole of the cell contain full set of chromosomes.
Two new cells are formed after cytokinesis.
I'm not completely certain but I believe that the answer is dehydration. When this occurs, monosaccarides are joined and water, or H2O, is a product of this.
