The DNA molecule is a double helix, shaped like a twisted ladder.
Answer:
this is beacuse stars are always in the sky
Explanation:
stars are always in the sky they are in the sky we just cant see it through our naked eye.. Also, while those super-massive stars will die suddenly as supernovae, most stars experience much slower deaths taking hundreds of thousands or millions of years to play out. Examples of famous stars already in the act of dying include Arcturus and Aldebaran.
DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.
<h3>
What is DNA Sequencing ?</h3>
DNA Sequencing is a technique to determine the bases, nucleic acid sequence in the DNA. It is important to know the functions of genes, coding and non-coding part of proteins, identify the diseases, effectiveness of drug delivery etc.
<h3>
What is Land plants and Stonewort ?</h3>
Stonewort is commonly known as Chara . It is a freshwater green algae which comes from the Charophyta division. Fossils of Charophytes shows that Stonewort is a type of algae which is 470 million years old.
Thus from the above conclusion we can say that DNA sequencing suggests that among the green algae, the Stonewort are most closely related to land plants.

Answer:
- Dependent variable: number of cells that are in one of the phases of mitosis
Explanation:
In an experiment, the independent variable is the variable that is not changed by the other variables that are being measured during the experiment (in this case, the independent variable is represented by the distances from the root cap). On the other hand, the dependent variable is the variable that is being measured/tested during the experimental procedure and, therefore, is 'dependent' on the independent variable. In consequence, in an experiment, the dependent variable is expected to change as a result of the manipulation of the independent variable.
Answer: Mitochondria
Explanation:
Mitochondria are oval shaped cell organelles bounded by a double membrane, and serve as a site of respiration or where energy is released from simple sugars like glucose.
Thus, the ability to produce energy makes mitochondria the power house of the cell
