The given question is incomplete as it does not have the options which are:
a) Sensory receptor
b) Sensory neuron
c) Motor neuron
d) Effector
e) Integration center
Answer:
The correct answer is option-Effector
Explanation:
A reflex arc is the mechanism of the neurons which controls the reflex action or involuntary responses or the instantaneous responses of the organisms.
The reflex arc involves the sensory receptors, sensory neurons (transmit signals from sense organ to spinal cord), motor neurons (transmit signals from spinal cord to muscle), Integration centre in the spinal cord and effector.
An effector represents the gland or the muscle which receives the transmitted signal from the motor neuron and responds by showing movements.
Thus, option-Effector is the correct answer.
Answer:
Option C: 50%ZA and 50% Za.
Explanation:
The genotypes of snakes are governed by Genotypic System Determination that is similar to birds, with Z and W sex chromosomes. In this case, males are the homogametic sex (ZZ) and females are the heterogametic sex (ZW).
Since albinism is a recessive condition, it is expressed by having two copies of the recessive allele on the Z chromosomes for males and just one copy to be expressed in females. Since the female is albino, thus her genotype will be (ZaW) with a representing the albino trait.
For the two organisms to be able to produce both the normal colouration and the albino condition, the father has to be heterozygote for the trait (ZAZa): having 50%ZA and 50% Za.
The relationship between the 2 species that would be mutually beneficial would be B. A flowering plant and a bee, the bee is able to obtain nutrients and essential necessities by the flower, pollen, and it also helps the flower by transporting the pollen from one flower to that of another one, where pollination can take place.
