Answer:
The pericardium is the most outer layer of the heart. Main function to protect the heart from external forces/entry.
Answer:
A) rely on protection and resources supplied from the maternal plant.
Explanation:
The embryo is a structure formed after the fusion of the male gamete and female gamete. A diploid zygote is formed after cellular division forms the embryo in the female gametophyte and therefore is considered the diploid tissue.
The embryo requires the nutrients for growth and absorb them from the surrounding female gametophyte structure like endosperm in the angiosperm. The embryos grow and form the sporophytic structure.
Thus, Option-A is correct.
Answer:
The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".
Explanation:
0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:
A: 3.21% (m/v) NaCl Solution = crenation (higher than 0.9% (m/v) NaCl)
B: 1.65% (m/v) glucose Solution = hemolysis (lower than 5.0% (m/v) glucose)
C: distilled H2O Solution = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)
D: 6.97% (m/v) glucose Solution = crenation (higher than 5.0% (m/v) glucose)
E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)
There may be many forms of a single gene. Each such form is called an allele
Of its valence electrons or the no. Of valences in its Valence shell .In case of noble gases, their outermost shell is absolutely crammed so no emptiness is available in the outer maximum shell. Thus the oxidation kingdom is 0(zero)for Noble gases. Because, they've complete electrons in their out maximum shell.
hope this helps
