<span>False. RNA has four different bases, adenine, guanine, cytosine and uracil. The first three of these are also found in DNA, but when it comes to RNA, there is no thymine, it is in fact replaced by uracil as the base to compliment adenine. So RNA has adenine, but not thymine.</span>
Answer:
C (Prophase)
Explanation:
All cells undergo division in order to produce more daughter cells. Cell division occurs immediately after the interphase, which is a resting and preparatory phase for mitosis or cell division. Prior to cell division, the DNA is found to be coiled around histone proteins to form a structure called CHROMATIN. The process of cell division occurs in four phases; Prophase, Metaphase, Anaphase, and Telophase.
In the Prophase stage, which is the first stage of mitosis, this Chromatin begins to condense or becomes compact by undergoing further coiling into a visible X-shaped structure called CHROMOSOME. This shape of the chromosome is as a result of the replication into sister chromatids that occurred in the S-phase of interphase.
<u>Sunspots</u> are temporary phenomena on the photosphere of the Sun that appear as dark spots compared to surrounding regions. They are caused by intense magnetic activity.
Answer:
The longer answer lies in the details of photosynthesis, the electromagnetic spectrum, energy and “special pairs” of chlorophyll molecules in each plant cell. ... As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Explanation:
Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. ... Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants
Answer: seen below
Explanation:
In vigorous exercise, your brain and body do everything they can to cool you off by increase the flow of blood to the skin where it can cool down with the aid of sweating , while in someone who has an infection they push the temperature inside your body to extreme levels by strengthening your immune system resistance to the infection, the immune system deliberately raises your body temperature as part of its strategy to kill the infection attacking you.
