“20.2 Graphical representation of vectors (ESAGK)
Vectors are drawn as arrows. An arrow has both a magnitude (how long it is) and a direction (the direction in which it points). The starting point of a vector is known as the tail and the end point is known as the head.”
An internal skeleton is used to help an organism hold its body up and keep from falling, while a stem stores nutrients, and produces new living tissue, and transports fluids.
The answer should be allele(s).
Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes.
However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing.
An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
Answer:
WBC.
Explanation:
WBC have cells, hence the name White Blood CELLS. They also contain a nucleus.
Answer:
The increased activity prior to the saccade reflects a shift in attention to the stimulus inside that neuron's receptive field.
Explanation:
They observed that the neurological basis of attention, first made in the superior colliculus has been extended to a number of areas in both the dorsal and ventral streams.
