1. Gene- a portion of DNA which codes a specific hereditary trait
2. Allele- alternate forms of a specific gene
3. Trait- A genetic characteristic of the individual
4. Chromosome - a thread-like molecule....
Answer:
The correct answer would be D.Alveolar sacs are surrounded by thin capillaries where gases can be exchanged.
Alveoli are tiny sacs which form the site of gas exchange in the lungs.
The features of alveoli which help in gas exchange are:
- They increase the surface area in the lungs thus, more space is available for gas exchange.
- They have very thin walls, as thin as the thickness of a single cell only.
- They are surrounded by a bunch of thin capillaries which exchange gases with alveoli.
Answer:
"Be freezing at night because the planet has no atmosphere" is the correct answer.
Explanation:
I was doing my reading in OW and I quote this is what OW said:
Temperatures during the day can reach 430°C (800°F), but can drop to -170°C (-280°F) at night because there is no atmosphere to trap heat.
Hope I helped:)
Have a great day!!!
Answer and Explantion
Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.
Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.
Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.
Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.
