Cacti had to adapt to absorb the proper amount of water needed to grow and thrive in a dry climate. Cacti have adapted to absorb moisture from their surroundings and store it inside. This allows cacti to properly distribute water when they need it for development and survival. This also prevents the cacti from dying during especially dry times, as it can release water that it has stored.
I hope this helps! :)
Answer:
transformation
Explanation:
Transformation is one of the three methods of genetic recombinant in bacteria. The other two are transduction and conjugation. Transformation occurs when the bacterial cells take up the DNA and which in turn changes their phenotype.
Transformation requires that there should not be any cell to cell contact. In the experiments performed by Griffith, the heat-killed virulent S strains were mixed with live R strains. The R strain took the DNA of heat-killed S strains which in turn converted them into the virulent strains. Since this horizontal gene transfer did not include any cell-to-cell contact, he called the process transformation.
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:
The given blank can be filled with corona.
Explanation:
The Moon moves in between the Earth and the Sun in a solar eclipse. When this takes place, a segment of the light of the Sun gets blocked. During a total eclipse of the Sun, the corona of the Sun can be witnessed shining in all the orientations surrounding the Moon. The only time when the corona of the Sun can be witnessed is during a total solar eclipse. Colorful lights from the chromosphere of the Sun and the solar prominences are also visible at the time of a total solar eclipse.
Answer:Double circulation has two components, pulmonary circulation and systemic circulation. Pulmonary Circulation : It is movement of blood from heart to the lungs and back. Deoxygenated blood of the body enters the righ auricle, passes into righ ventricle which pumps it into pulmonary arch,...
