Scientists have tried lots of different ways of predicting earthquakes, but none have been successful. They have a pretty good idea of where an earthquake is most likely to hit, but they still can't tell exactly when it will happen.
Answer: Symbiotic Relationship
Both fig trees and fig wasps are important for each others survival.
Explanation: The fig provides a joke for the wasps and the wasps provide pollen that the fig needs for the fruit to ripen.
It basically begins when a female fig wasp enters the fig and lays eggs ,they pollinate the fig with pollen that they had collected in their pouches after mating ,when the wasp enters the fig its wings and parts of antennae may get broken because of the small opening in the fruit ,the wasp completes it's task and never leave the fruit after.
Alleles are letters that represent dominant and recessive traits.
A capital letter represents a dominant trait
A lowercase letter represents a recessive trait.
Dominant traits over shadow the recessive ones. This is known as complete dominance.
Referring to your questions let's us the alleles HH, Hh, and hh for the height of the pea plants.
But what do those letters mean?
HH = homozygous dominant (Tall)
Homo means same.
hh = homozygous recessive (Short)
Now this is different: here's Hh.
There's a capital AND lowercase letter.
This means that the plant carries the gene for tall and short plants, and can pass on either trait to the offspring.
BUT the dominant always over shadows the recessive. So Hh is a tall plant.
Hh = heterozygous (hybrid) (Tall)
You can interpret hetero meaning different.
Now I hope you're with me!
For question two it asks if a short plant can ever be a hybrid.
Referring to what I just said, that answer would be no.
Because there is no dominant trait to over shadow the recessive.
And short plants have the hh alleles, and they are homozygous NOT heterozygous (hybrid).
I hope this helps, and makes sense! If you have any questions please let me know. Genetics can be confusing.
Fred must have suffered muscle atrophy.
Explanation:
Since Fred broke his leg and a cast was put around his leg,his orthopedic must have suggested restricted movement of his leg as a part of treatment.. Due to this immobilization the muscle mass of his leg may have got wasted and his leg became weak. Being too weak the leg may not have supported the body weight and Fred fell.
Starting from the outer part:
•Tunica externa (fibrous layer)
•Tunica media (smooth muscle)
•Tunica intima (endothelial cells layer)
