Explanation

- Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission.

- sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.

Correct Answer: A. impulses fromreceptors in the legs cannot travel to the brain

Correct Answer: D) in the ovary of a flower

Explanation

This Biology question is asking about where cells undergoing meiosis can be seen. Meiosis is a process of cell division that produces four haploid cells, each with half the number of chromosomes as the parent cell. The question is asking which structure will contain cells undergoing meiosis. Option A suggests that cells undergoing meiosis will be seen at the apices of stem and root. The apices are the tips of the stem and root, where growth occurs. However, meiosis usually occurs in reproductive structures, so option A is unlikely. Option B suggests that cells undergoing meiosis will be seen in the cortex of the stem. The cortex is the outer layer of the stem, and it contains various types of cells. However, meiosis is unlikely to occur in the cortex of the stem. Option C suggests that cells undergoing meiosis will be seen in the palisade mesophyll of the leaf. The palisade mesophyll is the layer of elongated cells located beneath the upper epidermis of a leaf. However, meiosis is unlikely to occur in the palisade mesophyll. Option D suggests that cells undergoing meiosis will be seen in the ovary of a flower, and this is the correct option. The ovary is the female reproductive organ of a flower that contains ovules, which will later become seeds if fertilized. Meiosis occurs during the formation of the ovules. In conclusion, cells undergoing meiosis will be seen in the ovary of a flower. Meiosis occurs during the formation of the ovules, which will later become seeds if fertilized.

Correct Answer: B. becoming a curse for us

Correct Answer: C. 28

Correct Answer: B. p = 5, q = -3

Explanation

If \(\begin{pmatrix} p+q & 1\\ 0 & p-q \end {pmatrix}\) = \(\begin{pmatrix} 2 & 1 \\ 0 & 8 \end{pmatrix}\)

Find the values of p and q

If \(\begin{pmatrix} p+q & 1\\ 0 & p-q \end {pmatrix}\) = \(\begin{pmatrix} 2 & 1 \\ 0 & 8 \end{pmatrix}\)

Find the values of p and q

p + q = 2

p - q = 8

\(\overline{\frac{2p}{2} = \frac{10}{2}}\)

p = 5

from p + q = 2

5 + q = 2

q = 2 - 5

= -3

Correct Answer: D. ankle

Explanation

The consonant sound represented by 'ncle' in 'uncle' is /nkl/. The word 'ankle' has the same consonant sound /nkl/.
