As with sea horses, sea dragon males are responsible for childbearing. But instead of a pouch, like sea horses have, male sea dragons have a spongy brood patch on the underside of the tail where females deposit their bright-pink eggs during mating.
There would be less variability in the genes of the watermelon plants and is denoted as option A.
<h3>What is Variability?</h3>
This is defined as the difference between organisms which is caused by genetic or environmental factors.
Using the seeds from the largest, tastiest watermelons will reduce variability over time because these characteristics will become dominant.

Answer:
The correct answer is - option B.
Explanation:
Greenstick fractures are the type of fractures where one side of the cortex is intact and flexed while the other side is fractured. This type of fracture known as the incomplete fracture,
If any fracture have two or more lines of fracture it is called as Comminuted fractures. Impacted fractures have one segment on other. Due to the performing same activity again and again stress fracture occures that is characterized by failure of one cortical bone.
Thus, the correct answer is option B.
DNA contains instructions for making the different molecules that a cell needs to grow and function. For example, proteins are made by translating mRNA.
<h3>What is DNA and what is its function?</h3>
DNA is the structure responsible for transmitting all genetic characteristics — such as eye, skin and hair color, physiognomy, among others — in the process of reproduction of living beings. In this way, the main function of DNA is to carry information contained in its sequences, called genes.
DNA is made up of two chains of polynucleotides (strand), which are made up of several nucleotides. Nucleotides are joined together by bonds called phosphodiester (phosphate group linking two sugars of two nucleotides).

Answer:
D. it is not true reproduction as a host cell is required to build new viruses
Explanation:
Viruses reproduce by using host cells to convert them into that virus. That is how they spread throughout your body.
