Explanation:
The homeotic genes refer to evolutionarily conserved genes that modulate the development of different structures in organisms of the same groups (in this case, plants). Moreover, homeobox genes are genes that encode transcription factors involved in the regulation of development in eukaryotic organisms. The knotted1 (<em>kn1</em>) gene is a plant homeobox gene is a member of the <em>kn1</em> homeobox (<em>knox</em>) gene family, which is responsible for maintaining indeterminacy and preventing cellular differentiation. In maize, <em>kn1</em> plays a key role in maintaining the cells of the shoot apical meristem in an undifferentiated state, being mainly expressed in shoot meristems during postembryonic stages of shoot development. It has been observed that maize mutant plants where <em>kn1</em> is ectopically expressed (i.e., in tissues in which this gene is not normally expressed) exhibit proximal-distal patterning defects.
The most important thing is to try and extinguish a fire if a fire extinguisher is near. If not, they second most important thing is to rush out of the lab using the fire escape route and call the local fire department which will then handle the situation.
Answer:
Air mass can be described as the volume of air present and the temperature of that mass of air.
Polar air masses are cold. They have less moisture content. The temperature of Maritime Polar air mass ranges from above freezing to below 70 degrees F.
Tropical air masses can be described as air masses that are warm and have a high moisture content. Temperature ranges between 70 degrees F to 90 degrees F.
Population because if they don't get water every day they will start to die in their population will start to fade out and then they'll become extinct
The correct option is A.
A lot of biochemical reactions occur per minute inside living cells and these reactions have to be sustained because the survival of living cells depend on them. For these reactions to proceed, energy is needed. This energy is usually obtained from the food which a living organism consumed. The mitochondria, which is the power house of the cell, is the one which convert the energy to the ATP form, which is usable by the cells.
