Answer:
True to some extent...
Explanation:
We can use bio-informatical tools like MEGA to see that to what extent an amino acid sequence shares ancestry with the other one. But these tools are based on statistical methods and mathematical modelling that make them unreliable as compared to the real world observations.

Answer:
If I were to choose a plant or animal which is interesting, I'd choose the "cactus."
Explanation:
A "cactus" is truly a splendid plant owing to its <em>ability to survive in the desert </em>or<em> periods of drought.</em> Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.
- One of these threats is the <em>"over-collection of cacti." </em>Due to its versatile use, the cactus is often sold as an ornamental plant.
- Another threat is the number of pests, such as <u>snails</u> and<u> slugs</u>, that attacks it yearly. It is a delicious food for<em> mealy bugs, red spider mites, gnats, flies, etc.</em>
- People often misunderstand the <u>cactus' water level need</u>s. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.
Answer: slip
Explanation:
The slip may occur while working on surfaces that are slippery because of wet and oily processes occurring at the workplace. The practices like floor cleaning, debris left on the floor and leakage of material can cause slips. The slip will occur when the floor provides a limited friction for walking.
The trip may occur while walking on the uneven floor. This may occur when the person's foot hit the objects that come in contact while walking. This disturbs the balance of the person while walking.
The slip and trip both can result in fall. This happens when the body gets deviated from the center of balance.
According to the given situation, a slip will occur as the working conditions are wet and the grates on the floor will slip due to lack of friction between the floor and the grates.
A petri dish is radial symmetry because it has similar parts regularly arranged around a central axis. A petri dish can be divided into the same half with the center of the top or bottom of the petri dish. This symmetry is also found in animals like the star fish and jelly fish
