Answer:
thamalus
Explanation:
Based on studies conducted by various neurologists, it can be said that in this situation that information was most likely first routed to the thamalus. This is a part of the brain that relays motor and sensory information to the cerebral cortex. It is also responsible for regulating sleep, consciousness and even alertness. Which is what was triggered (alertness) when you saw the spider crawling up your leg.
Answer: it is A.
Explanation: because they are both about the birds bones and birds need to fly if they don't have bones they can not fly
Answer:
All white-flowered snapdragons in the F1
Explanation:
The cross described above is an example of a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, one allele codes for red flower, while the other for white flower.
When both red and white flowered plants were crossed, an all pink-flowered plants resulted in the F1 generation. This is due to INCOMPLETE DOMINANCE, which is a genetic scenario whereby an allele does not completely mask the expression of another in an heterozygous state, instead they form a third phenotype that is intermediate to both parental phenotypes.
But in the case of crossing two white-flowered snapdragons, all the F1 offsprings will be white-flowered because the parents are homozygous i.e. contains the same alleles.
For example, RR (red flower) is crossed with rr (white), to produce an heterozygous/hybrid Rr (pink).
Hence if rr (white) and rr (white) crosses, all rr (white) offsprings will result.
