Answer:
A mutation is generally referred to as certain alternations in the gene whether it may be DNA sequences, which may be beneficial, harmful or of no significance to the mutant gene bearing organisms.
Explanation:
- A mutation that increases the ability to store moisture in a dry environment is obviously beneficial. Because it prevents dehydration and maintains normal functioning in spite of adverse conditions.
- A color mutation that decreases a bird's chances of sexual selection is beneficial in the sense that it prevent certain abnormalities in offspring like sexual dimorphism. Also sexual selection often proves to be a threat to the survival of the organisms as per handicap principle.
- A mutation in non coding region of DNA is harmful, as it is often observed to facilitate expression of wrong proteins at inappropriate places.
- A mutation in the that does not changes protein synthesis increased white pigmentation on a prey animal in snowy environment as it had prevented adaption of the prey and hence harmful for survival of it.
- A mutation decreasing plant's height in competition to light, makes them less exposed to sun energy important for photosynthesis and hence it is harmful for the plant.
The quickest way for an ant to go from the ground to the tree trunk is by walking straight towards the tree and climbing the tree trunk. Ant will walk straight if it is guided by the pheromone trail left behind by the other ants.
The ant first decides to explore the area for food and threats before taking a decision to walk away from its current location, i.e, the ground. The ant then starts to climb the bark of the tree to reach a higher ground. It does so by leaving a pheromone trail behind. This pheromone trail helps in guiding the other ants towards a possible food source.
Water and carbon dioxide are byproducts. Notice that photosynthesis and respiration are essentially the opposite of one another. Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
Answer:
Assuming you mean in a compound of elements: A name is just what you call it, and the chemical formula is what elements it is made of.
Explanation:
Take sodium chloride (Salt) for example. It's name is sodium chloride, but its chemical formula is NaCl. Na= Sodium, and Cl = Chlorine. So one sodium ion and one Chlorine ion create NaCl. Na+Cl=NaCl. And the name for the product of the formula is Sodium Chloride.
Another example is H2O (Water). H=Hydrogen and O=Oxygen. There are 2 hydrogens and one oxygen in H2O. H+H+O=H2O. The name for the formula is water.
