Density.
If the density is more than that of water than it sinks.
If it is less than it floats.
Density is the amount of mass in a certain space, therefore
D = M/V
Density = mass divided by volume
A <u>Scientific method </u>is a series of steps used to determine solutions based on needs and wants.
<h3>What is needs assessment?</h3>
A needs assessment is a process that bridges the gap between an organization's current state and the desired conditions. It is a systematic procedure for identifying and addressing performance gaps as well as repairing any defects that may occur in an organization.
<h3>What are the six steps of the scientific method?</h3>
- Describe the issue :Observation with intent
- research : learn more about the subject
- educated guess : hypothesis forecast the outcome of the problem
- experiment :Create a procedure for testing the hypothesis.
- analyze :Keep track of the experiment's outcomes.
- conclusion : compare the hypothesis to the results of the experiment
<h3>What are the Characteristic Features of Scientific Methods?</h3>
- Students learn to identify and formulate scientific problems correctly and in an organized manner using scientific methods.
- Students are trained in information processing techniques using scientific methods.
- Scientific methods help students develop the ability to think critically and rationally, allowing them to make decisions on logical and rational grounds.

Answer:
B. Arm length
C. Shape
D. Centromere placement
Explanation:
Cytogenetics is a discipline that study the structure and number of chromosomes including their morphology, position of the centromere, arm length, staining bands, etc. These features can be observed by microscope and enable us to identify different genome rearrangements (i.e., translocations, deletions, centric fusion, chromosome duplications, etc.) by ilustrating chromosomes in defined pictures referred to as karyotypes. In consequence, they are chromosome features that can be used in order to categorize different samples.
Answer:
Innate or natural immunity
Explanation:
Innate immunity is a defense system that we are born with and that protects us against antigens. It is the sum of all defense mechanisms that occur naturally to protect an individual from infectious diseases. They are physiological mechanisms that are present throughout the entire animal kingdom and it is an inherent quality of each species.
They are not specific to a given pathogen, nor do they generate memory
