In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. What is
Dmitriy789 [7]

Answer:

This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.

Explanation:

Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).

The pad of fatty tissue that covers the area of the pubic bone is called the ________.
Anettt [7]

The pad of fatty tissue that covers the area of the pubic bone is called the mons pubis

The pubic bone is protected by a fatty cushion called the mons pubis. The mons, or mons veneris in females, is another name for it. Although both have a mons pubis, females tend to have it more pronounced.

Females tend to have a large mound of tissue that is typically covered in pubic hair. During sexual contact, the mons pubis serves as a source of cushioning. Sebaceous glands that release pheromones to promote physical attraction are also found in the mons pubis.

The mons pubis is a part of the vulva. This is the rounded region in the bottom portion of the belly that is in front of the pubic bones (abdomen). At puberty, it grows hair all over it. The vulva has two skin folds.
