Answer:
The interphase: <em>DNA duplication</em>; The prophase: <em>Nucleus disappear</em>; The metaphase: <em>Chromosome line up at the middle of cell</em>; The anaphase: <em>Chromatids separation</em>; The telophase: <em>New cell membrane formed</em>; The cytokinesis: <em>Divided into two cell</em>.
Explanation:
A cell cycle includes 4 main phases: G0 phase, Interphase, Mitotic or Meiosis phase, Cytokinesis.
- G0: cell has left the cycle and stop dividing
- Interphase: including G1, S, G2: cell increases its size, and the DNA is duplicated to prepare for cell division.
- Mitotic or Meiosis phase: including prophase, metaphase, anaphase, telophase. In this stage, the nucleus and materials are divided.
- Cytokinesis: Cell divides into two daughter cells.
Answer:
E. ozone layer.
Explanation:
The pattern of temperature increase with height in the stratosphere is the result of solar heating as ultraviolet radiation in the wavelength range of 0.200 to 0.242 micrometre dissociates diatomic oxygen (O2).
The question is incomplete and no options are available. So, the answer includes all the common statements.
Answer:
Theophylline may be defined as a drug used to treat the different respiratory diseases like asthma and COPD. The proper dosage of the drug required for the treatment.
The client is undergoing for the treatment. The serum level can be used to determine the therapeutic levels. The nurse can say that the drug is showing negative or excess effect. The drugs showing some immune reaction due to its high level.
The first cells were probably photosynthetic
Answer:
<u><em>DNA is made of repeating units called nucleotides.</em></u>
Explanation:
DNA can be described as a double helix molecule made up of long polymer chains of nucleotides. The nucleotides which are present in a DNA are:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T)
The hydrogen bonds which occur in the pairing of nucleotides makes the double helix structure of DNA.
Adenine forms hydrogen bonds with Thymine.
Guanine forms hydrogen bonds with Cytosine.
The backbone of the DNA is made up of sugars and phosphates
