Answer:
A central nervous system is consist of brain and spinal cord. The brain is made of the cerebrum, cerebellum, and brain stem.
The parts of the central nervous system involved in given behaviors are as follows:
- <u>Listening to music:</u> The cerebrum in the brain is responsible for the behaviour of listening music as it functions for auditory stimuli (temporal lobe).
- <u>Realization of being thirsty:</u> limbic system in brain is responsible for the regulation of thirst.
- <u>Feel that soda is no longer cold: </u>Hypothalamus in brain controls the sense of temperature felt by the body.
- <u>Decide to invite a friend over: </u>The cerebrum functions for thinking and decision making.
Yes when a tadpole "evolves" it will grow into something different
Ans.
Cell-to-cell communication allows signalling of essential substances between the plant cells, which are surrounded by cell walls. The molecules used by plants for long-distance signalling are known as hormones, such as auxin, ethylene, and gibberelin.
These hormones are secreted by one plant cell and received by another plant cell, where it exerts it affect. Thus, the correct answer to be fill in the blank is 'option A). hormones.'
Answer: 200 seeds will be yellow.
Explanation: In this crossing, one parent will produce half of its gametes carrying allele Y and the other half carrying allele y. The other parent will have gametes with allele Y. After fecundation, the offspring could phenotype YY or phenotype Yy.
In genetics, Y is related to the dominant allele and y to the recessive one. In this case, having the Y dominant allele determine the color yellow. Therefore, as all of the offspring has the dominant allele Y for yellow, all of the seeds will be yellow, i.e., <u>200 seeds will be yellow</u>.
The answer is 3(x-2)(x+2)
