andre [41]

Answer:

a. amygdala

Explanation:

According to my research on studies conducted by various neurologists, I can say that based on the information provided within the question the part of the brain that was most likely under investigation in this study was the amygdala. This can be said because the amygdala is the part of the brain that is responsible for emotions, survival instincts (which dictates fear levels), and memory.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

What is natural selection? How does this work on organisms in nature? (should be at least 3 sentences)
BigorU [14]

Answer:

The natural selection is a theory made by Charles Darwin where animals better adapted to their environment tend to survive and produce offspring. for example, there are about 50% of beetle that are green and 50% orange.  If crows tend to eat green beetles more, there will be more orange beetle to produce offspring so there wood then be less green beetles to be eaten by crows.

An environment can change over time and this will cause for the animals living in the environment to adapt as well. These changes will occur when an animal with undesirable traits don't survive to reproduce. The offspring of individuals that do survive to reproduce will inherit their parent's desirable traits. Over many generations, the desirable traits will be seen in more-and sometimes all- of the individuals in the population

Explanation:

That is the natural selection told in my words, but please do your best to rewrite your own sentence/paragraph. Copying another's work is called plagiarism and any teacher can automatically give you a 0% for this.

Anyway, goodluck.

Someone please calculate the ratio of offspring please help pleaseeeeeeeeeeeeeeee
Over [174]

Answer:

2. 1 Pink : 1 white

3. 1 Red : 1 Pink

4. 1 Red : 2 Pink : 1 White

Explanation:

This question involves a single gene coding for flower colour in snapdragon plants. The alleles of the gene exhibits incomplete dominance i.e. the red allele (R) ia not completely dominant over the white allele (W), hence an intermediate pink phenotype (RW) is formed. Based on this, a red snapdragon will have genotype, CRCR while a white one will have genotype, CWCW. The intermediate pink phenotype will have a genotype, CRCW.

The image attached to this question shows four crosses between different traits.

In the second cross between a pink (CRCW) and white offspring (CWCW), 2pink and 2white offsprings will be possibly produced in the ratio 1:1.

In the third cross between a red (CRCR) and pink (CRCW) snapdragon, 2 red and 2 Pink offsprings will possibly be produced in a ratio 1:1.

In the fourth cross between a pink (CRCW) and pink (CRCW) snapdragon, red, pink and white offsprings will be produced in the ratio 1:2:1.

See attached image for the complete punnet square. Note that, there was a mistake in the Genotype of the last cross i.e. pink has genotype CRCW not CWCW.
