Hi, thank you for posting your question here at Brainly.
Chromatin contains proteins and DNA. The cellular division processes, mitosis and meiosis, condenses the chromatin to form chromosomes. They divide into two cells (mitosis), then two 4 cells (meiosis). The chromosomes contain the gene.
Answer:
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
Explanation:
If two heterozygous individuals have a child
i.e let the heterozygous individuals be = Xy
if both traits crosses together; their F₁ offspring will be; (XX, Xy, Xy, yy)
Xy × Xy
X y
X XX Xy
y Xy yy
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
If not my mistaken this would be the answer
The cell will change the concentration of water within the cell to match the concentration of water outside the cell.
Answer:
Pericardial sac has protective tole
Explanation:
Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:
- the outter coat-parietal pericardium
- the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).
Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.
C. They are pulled toward Earth by the force of gravity (and in Physics you would learn that the deceleration speed of gravity is -9.8m/s/s)
