The answer is polygenic inheritance.
Polygenic inheritance is responsible for traits that are controlled by two or more genes. It is also called multiple gene inheritance. Examples of polygenic inheritance are height, weight, skin color, eye color.
Since a great number of genes control one trait, it is expected that each one has<span> a relatively small effect</span>
Answer: 21%
Explanation:
The atmosphere is the gaseous portion of the planet Earth. It therefore consists of several gases and air particles.
In the atmosphere,
-Nitrogen is the most abundant gas with 78%
- Oxygen takes 21%,
- Carbon dioxide takes 0.03%,
- the remainder is unreactive gases and particles.
Answer:
my my teacher gives my class and I a mystery box for us to observe what's inside that box it was closed, as we was trying to know what's inside that box we were looking and thinking what does it sounds like, but my friend next to me says it sounds like a stapler and my other friend said it's not very heavy, as we were we said we could take another box just like that identified box and put a stapler since it sounds like a stapler and it's not that heavy as we know staplers are not that heavy. well we did that we check and our activity shows that the mystery box it slides and appear to be flat and all the box it slides in appear to be flat so that's the same thing as our box and the mystery box and we were looking at how does it sound when we close the box and everything we were checking how does it sound as we are observed that the mystery box it makes a metallic song when it strikes the side of the box an hour box the stapler makes a thudding sound when it strikes the side of the box and we also checked if the mass of the box was the same but it wasn't the mystery box was 270 g and our box was much more heavier which is 410 g so we were checking what was the really wrong thing we was checking and checking is like what should we do next, and we did in for the things in the box had to be different because our observation of the two boxes are different, and we observed yes things are different of course.
and there's a picture with the observation chart I will be showing it's above take a look and you will be have more understanding and knowledge about the really topic I am talking about thank you.
Answer:
The answer is below
Explanation:
There are different types of biological tools, with each of them having different functions. However, for the sake of the question, some of the popular tools will be listed here.
1. Stockroom tools: this includes:
Beaker: this is essential to take or storing small substances
Bunsen Burner: this is important in the biological lab to heat a substance
Flask: this is essential in holding liquid substance.
Pipette: it forms of a lab spoon that is used in mixing substances to form a compound or mixture
2. Computer and Imaging system: this is important in image analysis and sequence-analysis programs
3. Cell cultures: this is used in the biological lab to enhance the complex cell differentiation required in the experimentation of animal cell structure
4. Microscopes: this is essential in determining and examining the microscopic organism that we can not see with our makes eyes
Chromatography is a laboratory technique for the separation of mixture. It contains two components:
Stationary phase- substance that is fixed inside the column
Mobile phase- substance that is moving through the column.
Analyte is the mixture that has to be separated by chromatography.
When both are added to the column, mobile phase and analyte, components of the analyte will adhere to the stationary phase at different level and as a result travel at different speeds through the stationary phase as the mobile phase flows through it. The components that adhere more strongly to the stationary phase travel more slowly compared to those with a weaker adhesion. So, chromatography separate substances based on their adhesion for stationary phase.
