Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
Yes. Greenhouse gasses make it hard for heat to leave the atmosphere, but also hard for heat to enter the atmosphere. So once the heat is gone, it will be hard for earth to warm up again, thus causing an ice age
Answer:
No
Explanation:
A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).
These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.
Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.
Think about it like comparing the instructions for building a car to the instructions for building a bicycle.
Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.
It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.

<u>Sensory</u> memory.
Explanation:
Sensory memory is the type of memory that stores information for a very brief period of time it is even shorter than the time period of the short term memory.
Sensory memory helps the brain to hold the effects of a sensory stimulus for sometime even after the stimulus has ceased. This helps in continuous perception and processing of data in the brain.
The expression of continuous reading, writing and speaking are due to the existence of sensory memory.
If sensory memory does not function properly then, the synchronization of words and their understanding would have been impossible.
C-nucleic acid is a component of deoxyribonucleic acid which is the provides the cell with its genetic makeup as well as its genetic blueprint.
