Answer:
Polygenic.
Explanation:
A trait that is controlled by more than one gene is called polygenic which translates to "multiple genes".
B. a scanning electron microscope provides much better resolution than a compound light microscope.
Reasoning: The resolution of an electronic microscope is about 0,050 nm, whereas the resolution of a light microscope is about 200 nm.
If we name the gene for pods with A, than the alleles are: A-dominant, a-recessive.
The possible genotypes for the smooth pods are: Aa and AA, while genotype for constricted pods is aa.
If one parent has constricted pods and the other parent is homozygous for smooth pods there are two possible combinations:
P: AA x aa
F1: Aa Aa Aa Aa all of the offspring are constricted
Another combination:
P: Aa x aa
F1: Aa Aa aa aa half of the offspring are with constricted pods and half with smooth pods.
So, the correct answers are:
• all of the offspring will have constricted pods
• 50% of the offspring will have constricted pods and 50% will have smooth pods.
Carbon cycle :
- CO2 is given out when organism breathe
- Plants gather this CO2 to produce oxygen
- Oxygen that is produced by the plants is used for other organism's breathing which will given out another CO2 and repeat the cycle
Water Cycle :
- Water from the sea and lake is evaporated and Turned into Clouds
- When atmosphere cool it down, these clouds will condense and turn into rain
- Eventually this rain will flow back to the lake or sea and it will repeat the cycle
hope this helps
