1 Cardiac muscle cells
2 Smooth muscle cells
3 skeletal muscle cells
Answer:
<em>The correct option is B) Her title is accurate because one extreme is favored.</em>
Explanation:
In ecological studies, directional selection can be described as a selection due to which an extreme phenotype is favoured by natural selection and evolution causes the change in allele frequencies in favour of the extreme phenotype.
In the condition described in the question, the phenotype for eating insects was the extreme phenotype which was favoured by natural selection. The allele frequency for this extreme phenotype became abundant due to evolution. Hence, option B is correct.
Answer:
The correct answer is - damaged, effector organ, neurilemma, damage, distance, cell body, decreased.
Explanation:
PNS axons are prone to cuts, and other types of injuries. A damaged axon can regenerate if the effector organ remains intact and a critical amount of neurilemma is found.
The degree of success of these axons regeneration depends upon factors that are (1) the amount of damage, and (2) the distance between the site of the damaged axon and the cell body it innervates The possibility of repair is reduced with an increase in either of these two factors. Neurolemmocytes play an active role in regeneration
Answer:
The correct answer would be B-80/200.
Allele frequency is defined as relative occurrence of the allele at a particular locus in a given population.
We have a sample population of 100 chickens where
Frequency of homozygous dominant trait (CC) = 45
Frequency of homozygous recessive trait (cc) = 25
Frequency of heterozygous dominant trait (Cc) = 30
Total alleles would be = 100 x 2 = 200
Total number of observed copies of C (dominant allele) = (45 x 2) + 30 = 120
Similarly, number of observed copies of c (recessive allele) = (25 x 2) + 30 = 80.
Hence, the frequency of allele C = 120/200 = 0.6
Frequency of allele c = 80/200 = 0.4
Answer:
Ia tidak mempunyai badan fizikal.
Penjelasan:
Jisim udara tidak diukur oleh keseimbangan tuas atau keseimbangan berat yang lain kerana mustahil untuk mengukur jisim udara. Hanya dua sifat udara yang dapat diukur seperti kadar aliran dan tekanan. Imbangan tuas mengukur berat bahan-bahan yang mempunyai badan fizikal sehingga sebab itu jisim udara tidak dapat diukur kerana tidak mempunyai badan fizikal. Udara mempunyai jisim tetapi tidak mempunyai badan fizikal sehingga mustahil untuk mengukur beratnya.
