Answer:
Charles Darwin had concluded that these birds had somehow evolved to adapt based on the island they were on. Each island had different food sources so if these finches wanted to survive they had to change. Each finch adapted to their environment due to forcefully evolving to survive.
Explanation:
Answer:producers convert light energy into chemical energy
Explanation:
Answer:
Independent variable: The fertilizer given
Dependent variable: Daily plant growth
Constants: How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
Explanation:
Independent variable of an experiment is the variable that is changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment where Sherri wanted to test what fertilizer worked best on her tomato plants. She used 4 different brands of fertilizer. Hence, the FERTILIZER is the independent variable
On the other hand, the dependent variable is the variable that is measured in the experiment. It is the variable that responds to the independent variable. In this experiment, the DAILY PLANT GROWTH is the dependent variable.
Constants are variables that are kept unchanged or constant throughout the experiment. In this case, the constants or controlled variables are: : How much water they receive daily, How much sunlight the plants receive, type of plant (tomato plant)
The independent variable in Sherri's experiment is the type of fertilizer used. The dependent variable is the daily growth of the plants. The controlled variables include the type of plant, the amount of sunlight received, and the amount of water given daily.
In this experiment, the independent variable is the fertilizer given to each plant. This is because the type of fertilizer is what is being changed or manipulated in this experiment to observe the potential changes or effects on the plants.
The dependent variable in this scenario is the daily plant growth. It is called 'dependent' because its value might change depending on the effect of the independent variable (the fertilizer).
The controlled variables for the experiment are the type of plant, how much sunlight the plants receive, and how much water they receive daily. These are conditions that were kept the same for each plant to ensure that the only difference between the plants was the type of fertilizer used.

Resistant bacteria are polyploidy and can resist the antibiotic, a trait that is passed on to their offspring.
Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited.
Bacteria have purposefully directed their immune system to resist the effect of the antibiotic.
Answer:
The correct answer is "Some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited".
Explanation:
Antibiotic resistance is a serious health issue that occurs when bacteria gains resistance against certain antibiotics, which reduces or eliminates the effectiveness of the treatments. The best explanation for this phenomenon is that some bacteria have randomly mutated to resist the antibiotic, and this resistance is inherited. This happens particularly when people do not take the full treatment or take treatment without diagnosis. In consequence, the populations of bacteria are not fully eliminated, increasing the probability of survival for bacteria that randomly mutates towards resisting the treatment.
Answer:
23
Explanation:
Human somatic cells have 46 chromosomes, including 22 homologous pairs and one pair of nonhomologous sex chromosomes. This is the 2n, or diploid, condition. Human gametes have 23 chromosomes, one each of 23 unique chromosomes. This is the n, or haploid, condition.
