Answer:
Thigmotropism is a plant's response to touch.
Thigmotropism is a plant's response to an external stimulus.
Thigmotropism can occur quickly or slowly.
Thigmotropism may involve the way in which a plant grows.
Thigmotropism may involve the closing and opening of plant leaves.
Sorry its a very long answer-
1.) Failure to maintain the rule of law
The government's repeated failures to bring levels of violent crime under control contributed to an environment which saw people resort to violence without fear of arrest or successful prosecution.
2.) Border control
3.) Corruption
4.) Employment
5.) Education
This has been government's biggest failure and carries much of the blame for the high unemployment levels. It is arguable whether current state education is in its totality any better than that under apartheid. Only 1% of black matriculants achieve a good HG maths pass.
The education system is a good example where policy failures in one area compounded those in another.
6.) Slowing economic growth
7.) Foreign policy
8.) Service delivery
9.) Race relations
Answer:
Yes! ( True )
Explanation:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. ... Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge
Chlorine-the chemical element of atomic number 17, a toxic, irritant, pale green gas
atomic number-the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
Answer:
There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.
Explanation:
The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.
