Answer:

Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Explanation:

Similarity

Both the aldehyde and ketone have C=O group

Difference

In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO

while in ketone the function group is C=O only that is bonded to two carbon atoms.

Example

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

mojhsa [17]

Answer:

B. Primary spermatocytes

Explanation:

The germ cell line is a group of cells found inside the seminiferous tubules. This germ cells undergo mitosis (creating spermatogonia) to have a steady supply of cells that will divide by meiosis to produce gametes. When spermatogonia divide by meiosis at the end of meiosis I the newly created cells are known as primary spermatocytes.

(will give brainiest if right) Peppered moths are dark colored when they carry the dominant (D) allele and light colored when th
kaheart [24]

D. DD = 0.0225; Dd = 0.1275; dd = 0.7225

The value of Dd is different in question.

<u>Explanation:</u>

Given -

Dark colored = DD, Dd

light colored = dd

Frequency of allele D = 0.15

Frequency of allele d = 0.85

Hardy-Weinberg equilibrium is applied.

DD = 0.15 X 0.15 = 0.0225

Dd = 0.15 X 0.85 = 0.1275

dd = 0.85 X 0.85 = 0.7225

Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
