Answer:
39 double-helical DNA molecules will be presenet in sperm and 39 in egg.
Explanation:
Each chromosome is made up of histone protein and a molecule of DNA.
Each cell contain double number of chromosomes (2n) except a few exceptions like sperm (1n) and egg (1n).
Human body cells contain 46 chromosomes while sex cells contain 23 chromosomes because of meiosis. Similarly dog cells contain 78 chromosomes while their gametes i.e egg and sperm each contain 39 chromosomes. The fertilization of sperm and egg will restore the chromosome numbers.
<em>As there is only one double helix DNA present in chromosome, so there would by 39 double helix DNA in sperm and 39 double helix DNA in egg. </em>
Imagining the illustration where a<span> pencil is beside a metric ruler, </span>scaled from 1 centimeter to 10 centimeters, with markings for millimeters between each number and o<span>ne end of the pencil is beside the 0 on the ruler, and the pencil point is midway between the 5 and 6, we can conclude that the precise and accurate measurement of the ruler would 5.5 centimeters. Since the point is pointing in the midway of 5 and 6, we can interpret that the point is pointing in the exact half between 5 and 6 thus we can conclude that this would be a 0.5 addition to 5, giving us the 5.5 cm.</span>
Answer:
D. Commensalism
Explanation:
The relationship between a remora and a shark is an example of commensalism - it's good for one side but neither good nor bad for the other. The remora attaches itself to the shark and gets the benefit of eating the shark's leftovers, but there is no harm or benefit for the shark, and the shark doesn't eat the remora like in a predator/prey relationship.

Please can I have brainliest
Answer:
Velocity vs Time: The object's velocity increases as it accelerates at the beginning of the journey. It remains the same in the middle of the journey (where there is no acceleration). It decreases as the object decelerates at the end of the journey.
