<span>Cells in a meristem differ from cells in other types of plant tissue differ in that they continue to divide. They are embryonic tissue that never differentiated or matured, and they give the plant the ability to grow. They are true stem cells in that they continue to divide via mitosis, and a portion of them remain undeveloped throughout the life of the plant. They are totipotent by logic, which means that any adult plant cell can be derived from them. It is this quality that allows a plant to grow new leaves if some are torn off and that scientists strive to unravel.</span>
Answer:
A
Explanation:
Signal loop is composed of negative and positive feedback mechanisms. The positive feedback increases the change in the system while the negative feedback reduces it. The ideal balance between the two feedback loops is called homeostasis.
Food and nutrition are fundamental to military capability. Historical examples demonstrate that a failure to supply adequate nutrition to armies inevitably leads to disaster; however, innovative measures to overcome difficulties in feeding reap benefits, and save lives. In barracks, UK Armed Forces are currently fed according to the relatively new Pay As You Dine policy, which has attracted criticism from some quarters. The recently introduced Multi-Climate Ration has been developed specifically to deal with issues arising from Iraq and the current conflict in Afghanistan.Answer:

Answer:
180seconds
Explanation:
From the question, Kepler-186f is an exoplanet that orbits a star called kepler-186, other than the Sun.
Distance of the star (kepler-186) away from the planet is 5.4 x 10^10 meters
To calculate how long i.e. time, a light moving at an average speed of 3.0 x 10^8 m/s will get to the exoplanet from the star, we use the following formula;
Speed (m/s) = Distance (m) ÷ time (s)
Time = Distance/speed
Time = 5.4 x 10^10 ÷ 3.0 x 10^8
Time = 5.4/3.0 × 10^ (10-8)
Time = 1.8 × 10^2
Time = 180seconds.
