Answer:

is created from careful research and logical reasoning

is able to be tested using validated techniques

 

Explanation:

A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.

Explain how predator and prey populations limit each other growth rates.
EleoNora [17]
Notice that independently, the prey population goes up, if the predator's population is low. One interpretation is that there are not enough predators to really make a dent in the prey's population. But as the prey's population increases, they become easier targets for the predators since there are so many. As predators feed on prey, the predator's population increases (more food, can sustain a bigger population) and the prey's population decreases. As less and less prey are available to hunt, the predator's population also decreases.

Note that it need not be this cyclical, the trend can go to an equilibrium point where the populations do not fluctuate all that much.


the predator eats the prey limiting them to not overly grow. And the prey do not overly grow limiting the predators population to not overly grow as well. hope that helps

Describe how scientific investigations lead to new scientific questions.
otez555 [7]

Answer:

Scientific investigations produce evidence that helps answer questions and solve problems. If the evidence cannot provide answers or solutions, it may still be useful. It may lead to new questions or problems for investigation. As more knowledge is discovered, science advances.

Another characteristic that you want to include in the introduction is bacterial reproduction. Prokaryotic cells have only one c
Solnce55 [7]

Answer:

The correct options are C and D.

C. Each daughter cell is an exact copy of the other, both genetically and morphologically .

D. Due to the stretching of the cytoplasmic membrane, both cells will contain a complete genome

Explanation:

Binary fission can be described as a method of asexual reproduction in which a parent cell replicates and splits into two new daughter cells. As a result of binary fission, the daughter cells formed are exactly similar to the parent cell. It is one of the most common methods by which a bacterial cell divides.

Other options like the option B are false because the daughter cells will not be permanently smaller than the parent cell. They will grow in size.
