Answer:
4 Fe + 3 O₂ → 2 Fe₂O₃
Explanation:
Let's start with the oxygen.
Reactants - 2
Products - 3
What number do 2 and 3 have in common? 6.
Put a 3 in the reactants and a 2 in the products to balance the oxygen.
Fe + 3 O₂ → 2 Fe₂O₃
Now let's look at the iron.
Reactants - 1
Products - 4
Put a 4 in the reactants to balance the iron.
4 Fe + 3 O₂ → 2 Fe₂O₃
The equation is balanced. Hope that helps.
We'll make the alleles: Cc.
C is a healthy parent, and c is the cystic fibrosis (recessive).
If you make a punnett square and the parents are both Cc (healthy), then you would get CC, Cc, Cc, and cc. That cc is a 25% chance that the offspring will have that, which means there is a 25% chance the child will have cystic fibrosis.
Two healthy parents can have a child with cystic fibrosis if both the parents have the dominant allele and recessive allele, if both the parents have heterozygous alleles.
Answer:
having more air spaces around the spongy mesophyll cells
Temporary storage sites in the cytosol for substances such as pigments or nutrients are called inclusions.
Pigments are the compounds that have a certain color and provide color to other structures indie the body. For example in plants chlorophyll is the pigment that provides green color to the leaves and stem. In humans and other animals, the blood consists f red colored pigment called hemoglobin.
Inclusions are the non-living objects inside the cell. They can be anything like pigments or any other molecules, that performs no function inside the cell. They are also called ergastic substances and do not even have any membrane.
