Answer:
2.3 and 4 only
Explanation:
Mutation is an alteration in the gene of an organism, which can cause some physiological and physical changes in the organism.
Mutation can have a favorable positive effect on an individual (e.g increasing microorganisms resistance to antibiotics) increasing its chances of adaptability and survivability, it can have a negative effect on the individual (e.g cancerous cells) which can reduce its survivability, and can have no effect at all on the individual (e.g having eyes with 2 different colors).
<span>The body needs oxygen for cellular respiration. When doing strenuous activity, such as lifting weights, the mitochondria cannot get enough oxygen. Without oxygen to act as an electron receptor, the body creates lactic acid to "reset" coenzymes to continue respiration.</span>
The answer is c, they have to use binary fission to divide
Hope this helps!
Depending on how good that species is at adapting to new environments that species of animals could adapt overtime, or die
Answer:
1. Producers create energy for other organisms to consume.
2. It converts sugars to usable energy that all organisms need
Explanation:
All living organisms require energy, which they obtain by feeding on one another in an ecosystem. The series of feeding steps involved is called FOOD CHAIN. Food chain always starts with an organism called PRODUCER, which is an autotroph i.e. capable of producing its own food by using light energy from sunlight e.g plants. All other organisms in the food chain are directly or indirectly dependent on plants to get energy. This is because plants and other autotrophs create the energy that is being transferred as the food chain progresses.
2. Cellular respiration is an important phenomenon for all living organism because it is the metabolic process by which they obtain the usable energy by their cells i.e. ATP. Food molecules in form of sugar (glucose) eaten by organisms are broken down in the presence of oxygen (aerobic) to yield ATP molecules, which is the energy currency of every living cell. This energy is used to perform the organism's life activities.
