Answer:
well with out it we won't understand dna
but heres the scientific answer
Explanation:
DNA replication allows for organisms to be reproduced from the parent.
After a sperm (from male) and egg (from female) cell have combined, they immediately start to divide. At this point, the cell is called a zygote.
In order for the cells to divide, they need DNA from the mother. They don't steal it. They just replicate it. For a cell to use DNA, it needs to be in the form of a chromosome, a tightly-packed DNA structure
DNA replication allows for organisms to be reproduced from the parent.
The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. As the Earth travels around the Sun, the hemisphere that is tilted towards or away from the Sun changes.
Answer:
mutacion en el material genetico
Explanation:
Explanation:
The label A represents mitochondria.
The mitochondria is also called the powerhouse of the cell which converts glucose to energy rich molecules of ATP.
Label B represents nucleus.
Nucleus contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.
Label C represents lysosome.
Lysosomes contain digestive juices which breaks down large cell parts and large molecules and helps in intracellular digestion.
Label D represents rough endoplasmic reticulum having ribosomes.
The rough endoplasmic reticulum provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
The planets that reside in the <u>Outer </u> region of the solar system are Jupiter, <u>Saturn</u>, Uranus, and Neptune. Although these planets are made up of lighter elements, they have a solid core. The atmosphere of all these planets is made up of hydrogen and <u>helium</u>. In addition to these two elements, the planets Neptune and <u>Saturn</u> contain methane.
