The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.
<h3>What is Cladogram?</h3>
A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.
In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.
The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.
Therefore, it is well described above.

The two cells that result from a single cell need to have the same amount of genetic material as the initial cell, therefore the DNA needs to be duplicated before the cell divides.
The sister chromatids are attached together so that during anaphase the daugther cells will receive the same chromosomes

The use of electronic instruments or other techniques to monitor and change subconscious activities, many of which are regulated by the autonomic nervous system, is called biofeedback.
<h3>What is biofeedback?</h3>
A mind-body approach known as biofeedback employs a variety of monitoring tools to give the body's physical functions, which are typically controlled by the body's automatic systems, conscious control. There are several kinds of biofeedback instruments that can be used to track the development of the activity and show the efficacy of the therapy as it is being administered.
The equipment that measures the following uses biofeedback the most frequently:
- brain activity
- respiration rate
- blood pressure
- heartbeat frequency and heartbeat variability
- tension in muscles
- electrification of the skin
- skin temperature
Devices used to measure body change are:
- Electromyogram (EMG): To measure muscular tension, use this.
- Electrodermal activity (EDA): This measures variations in perspiration rate.
- Measures of finger pulses: These evaluate heart rate and blood pressure.
- Electroencephalogram (EEG): This is used to assess brain electrical activity.

1: the seasons change primarily from getting closer to the sun or farther- also to the amount of sunlight reaching the earth
2: around this area you would get more sunlight when will then make it hotter
3: because of the northern hemisphere it will always be colder than the southern <span>hemisphere
4: it is mainly the amount of sun that is hitting the planet not primarily the closeness of it
5: well this one is up to you i dont know were you are.
hope i got you in time.</span>
