food vacuole or granule:- used to contain food for digestion .
contractile vacuole :- used to remove excess water.
follow me .....☺️☺️☺️nice study
Count the number of same elements before and after →
Make sure number of same elements on both sides are equal
2N on the right side, so it is 1N2
Answer:
The DNA sequence that produced the mRNA sequence uracil, guanine, cytosine, guanine adenine uracil adenine adenine during transcription is adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine.
Explanation:
Transcription of DNA into messenger RNA (mRNA) is a process in which the specific nucleotide sequence is transferred from one molecule to another, through the synthesis of mRNA molecules from a DNA strand.
The complete transcription process is done by nitrogenous base complementarity, where mRNA receives the sequence of complementary bases according to the DNA sequence:
- <em>Adenine</em><em> is complemented with uracil, since in RNA the thymine is substituted by this uracil.
</em>
- <em>Thymine</em><em> is complemented with adenine.
</em>
- <em>Cytosine</em><em> is complemented with guanine.
</em>
- <em>Guanine</em><em> is complemented with cytosine.
</em>
Thus an <u>uracil mRNA sequence, guanine, cytosine, guanine adenine uracil adenine U-G-C-G-A-U-A-A comes from a DNA sequence adenine, cytosine, guanine, cytosine, thymine, adenine, thymine, thymine or A-C-G-C-T-A-T</u>.
Answer:
True
Explanation:
Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.
Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart. It is said that some slight modifications to care for coronary heart disease include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.
Hostility levels is also related as a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.
