In plants the reproductive structure that produces pollen and seeds is the xylem is the answer
Observation is a factual statement that cannot be changed or replaced.
Explanation)
Hypothesis is a tentative statement that can be tested.
Scientific law and theory are considered a fact but can be disproven if new evidence emerges.
Graph c is the only graph that shows a growth curve and a carrying capacity so it is graph c
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.
Answer:
Explanation:
1. Blood Plasma: this is made up óf water, salts and protein. And it makes up more than half of the total volume of blood
2. Erythrocytes are also known as the red blood cells which makes up some of the solid part of the blood. They are packed with haemoglobin which helps to carry oxygen and they also gives blood the characteristics red color
3. These are also called white blood cells that function in producing antibodies that fights infection. Some types are monocytes, neutrophils, eosinophils etc.
4. Blood platelets: these also make up a part of the solid portion of the blood. They aid in blood clotting preventing blood loss.
