The answer that best fits the description above is the hormone GLUCOCORTICOID. This was according to Hans Selye, an Austrian-Canadian endocrinologist. According to him, ill health induced by exposure of chronic stress is due to the secretion of the hormone glucocorticoid.
Answer:
3/16
Explanation:
<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.
Assuming the eye color is represented by E and the wing shape is represented by W. At F2
EeWw x EeWw
E_W_ - 9/16 (dominant for both eye color and wing shape)
E_ww - 3/16 (dominant for eye color and recessive for wing shape)
eeW_ - 3/16 (recessive for eye color and dominant for wing shape)
eeww - 1/16 (recessive for both eye color and wing shape)
<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>
During an influenza outbreak, many people get infected and die. However, part of the population acquires immunity and survives. This is due to variations in the genotype and phenotype among individuals in the population. Probably a particular phenotype confers resistance to influenza. Therefore, this population is able to grow and develop to maturity and reproduce. Their genes are therefore passed over to subsequent generations.
Answer: option A - threat, after habitat loss, to native species of plants and animals and to the maintenance of biologically diverse ecosystems
Explanation:
Invasive species refers to organisms that appears at a particular habitat that has just undergone an environmental unfavorable condition.
These INVASIVE SPECIES poses THREAT to the native organisms, because they usually possess:
better resistance to disease,
higher reproductive rate, etc.
So, even when native organisms migrate or dies, Invasive species REMAINS. As a result, they threaten the maintenance of a biologically diverse ecosystem
