The greatest number of shared derived characters should be found in two organisms that are placed in the same kingdom class.The biggest quantity of the offshore fields drives characters must be observed among the 2 organisms which are the member of the identical kingdoms magnificence area family
Shared derived tendencies derived tendencies, individual states which are shared through species and which are exceptional from the ancestral species. a collection or member this is intently associated however now no longer a member of the organization being studied.
Cladistics /Phylogeny- is a exceedingly new device of class that makes use of shared derived tendencies to set up evolutionary relationships. A derived trait is a function that advanced handiest in the organization beneathneath consideration. A phylogenetic tree primarily based totally on a cladistic evaluation is referred to as a cladogram.

The correct option is (e) sensory neuron to motor neuron, responsible for the sensitization of the withdrawal response.
The central nervous system receives the excitation from a sensory neuron that has been stimulated by its nociceptors. Notably, these fibres deliver excitement to the sensory neuron's cell body, which is located in the spinal cord's dorsal root ganglia. The sensory neuron in the dorsal root ganglion transmits excitatory postsynaptic potentials (EPSPs) to motor neurons and interneurons after receiving the action potential from these fibres.
By releasing neurotransmitters into the central nervous system, the sensory neuron does this. Excited somatic motor neurons contract and depolarize the targeted muscles to complete the withdrawal reflex. The motor neuron, which leaves the spinal cord and enters the peripheral nervous system, is where this depolarization travels.
Therefore, sensory neuron to motor neuron is responsible for the sensitization of the withdrawal response.

Answer:
Independent variable: varying amounts of light
Dependent variable: plant growth
Explanation:
The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.
The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of African ancestry. This is supported by two mechanisms: heterozygote advantage and gene flow.
Heterozygote advantage
When an allele is said to be heterozygous, it is carrying one copy of a gene. For example if one carries a copy of sickle cell allele, it will stay in the population even after many generations — natural selection will not be able to remove it and it will be passed on through generations. So, having one copy of that allele is advantageous but not deleterious.
Gene flow
With humans migrating throughout the different parts of the world, sickle cell allele is passed from one person to another or in different populations. It is actually advantageous to have one copy of this allele especially if there’s malaria in the area, which the allele is resistant.
Answer:
A, O
Explanation:
O is oxygen, which is a gas at room temperature. It cannot conduct electricity as there are no delocalised electrons free to carry and electric charge.
