Correct Answer: B) phenotype

Explanation

An organism's physical observable characteristics are referred to as its phenotype. This includes traits such as eye color, hair color, height, and other physical features that can be seen or measured. The phenotype is determined by both genetic and environmental factors. Genes provide instructions for the development of an organism's physical traits, but the expression of those genes can be influenced by environmental factors such as nutrition, temperature, and exposure to toxins. In contrast, an organism's genotype refers to its underlying genetic makeup, which includes all of its genes, whether or not they are expressed. Alleles are different versions of the same gene, while a locus is the specific location of a gene on a chromosome. Therefore, the correct answer to this question is option B, phenotype, as it refers specifically to an organism's physical observable characteristics.

Correct Answer: A) dioecious

Explanation

This Biology question is asking which of the options is likely to encourage inbreeding in plants. Inbreeding is the mating of closely related individuals. Option A, which is dioecious, is the correct answer. Dioecious plants are those that have separate male and female plants. This means that the male and female plants are not able to mate with plants of the opposite sex. As a result, they are more likely to mate with plants that are closely related to them, which can lead to inbreeding. On the other hand, protandrous plants have male reproductive organs that mature before the female organs, while monoecious plants have both male and female reproductive organs in the same plant. Hermaphrodite plants, like monoecious plants, have both male and female reproductive organs, but they are not the best option for inbreeding because they are able to self-pollinate, which reduces the need for inbreeding. In conclusion, the correct answer to this question is Option A, dioecious plants, as they are more likely to encourage inbreeding in plants.

Explanation

\(y = 2x^{2} + x - 3\)

\(\frac{\mathrm d y}{\mathrm d x} = 4x + 1\)

At (2, 7), the gradient is \(4(2) + 1 = 9\)

The gradient of normal = \(-1 \div 9 = \frac{-1}{9}\)

Equation of the normal = \(y - 7 = \frac{-1}{9}(x - 2)\)

\(9y - 63 = 2 - x\)

At the point of meeting the x- axis, y = 0

\(0 - 63 = 2 - x \implies x = 65\)

The coordinate of P = (65, 0).
