Answer:
Explanation:
All the sensory information through sensory neurons must pass through the thalamus.
<u>Thalamus:</u>
- connects cerebral cortex and midbrain.
- collects information from the midbrain and passes it to the cerebral cortex.
- is involved in more functions such as; detects sensations of visual, auditory, and gustatory systems.
- is concerned with memory, emotions.

False is my guess because thats like juging
and that wouldent make sense
Associative learning is the event may be two stimuli or a response and its consequences
The unusually high frequency of "blue skin" in the area is an example of <u>genetic drift</u>.
<u>Explanation:</u>
It is a shift in the occurrence of an established gene variant within a population due to spontaneous organism screening. The offspring alleles are a composite of those in the parents and opportunity has a role to play in deciding whether or not a given person persists and reproduces.
The bottleneck impact is an interesting instance of genetic drift which take place when the population size is drastically reduced. Occurrences like natural disasters such as earthquakes, floods, fires can destroy a city, eliminate most people and leave a tiny, random assortment of survivors remaining.
The possible genotype would be when one of the parent is homozygous dominant - Phenotype ratio= 16:0, genotype ratio= 1 YYRR : 1YYRr: 1 yYRR: 1 YyRr.
when one of the parent is homozygous recessive the phenotype ratio is 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle and genotype ratio = YyRr: Yyrr: yyRr: yyrr or
1:1:1:1 genotype ratio.
Explanation:
The data given:
yellow and round dominant --- Y R
Green and wrinkle recessive ---- yr
It is given a true breeding plant, which means the parent plant is homozygous for the trait. Let one of the parent be YYRR
Also it is given that it was crossed with heterozygous parent so the other parent be YyRr
The cross between them is shown in punnet square as:
YR Yr yR yr
YR YYRR YYRr yYRR YyRr
YR YYRR YYRr YyRR YyRr
YR YYRR YYRr YyRR YyRr
YR YYRR YYRr YyRR YyRr
4 YYRR: 4 YYRr: 4 YyRR: 4 YyRr
thus genotype ratio is 1:1:1:1
phenotype ratio all 16 are yellow and round.
In case when either parent is homozygous recessive is crossed with heterozygous parent. The punnet square for this is shown as:
yyrr X YyRr
YR Yr yR yr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
4 YyRr: 4 Yyrr: 4yyRr: 4yyrr
1:1:1:1 genotype ratio
phenotype ratio = 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle.
Thus phenotype ratio is 1:1:1:1
