Answer:
After 14 years the population of these birds reached to 300.
Explanation:
The main reason for the extinction or decrease in population of these birds are over hunting or the introduction of invasive species in the ecosystem. Due to over hunting by humans many beneficial species are extinct which causes imbalance in the ecosystem which can't be corrected. These population should be increased by providing a suitable environment to these birds.
Answer:
C. More than 5 fingers/toes on each hand/foot
Explanation:
According to the given information, polydactyly is an autosomal dominant trait which means that the phenotype would be expressed in both homozygous dominant and heterozygous dominant genotype.
The given genotype is heterozygous dominant. The individuals with heterozygous dominant genotype would exhibit the polydactyly and would have more than 5 fingers and toes on each hand and foot.
The impact in this case is the ventricles will beat more slowly.
Sinoatrial node acts as a pace maker for the heart skipping the plateau phase and the electric impulses are created here. This node lets the blood into ventricles.
Atrioventricular node acts as controller of heart rate and serves as an electrical relay station. This node connects the right atrium and right ventricle.
B. Resistance is the tendency for materials to oppose the flow of electric charges.
Answer:
15.87%
Explanation:
<em>Carl's percentage error would be 15.87%.</em>
From the data, the hypothesized number of birds Carl could identify is 73.
The actual number of birds he was able to identify is 63.
The margin of error between the two = 73 - 63 = 10.
Hence, percentage error = error/true measurement x 100%
= 10/63 x 100% = 15.87%
