The first one. Mary asked how much the puppy cost.
I’m almost sure it’s called the Polar regions but I can’t remember much
Answer:
1:2:0
Explanation:
If two recessive lethal alleles come together, they will be expressed and lead to the offspring's death. Let the dominant allele be S and the recessive allele be s. Here, the two individuals are heterozygous for it. So when they mate:
S s
S SS Ss
s Ss ss
1/4 have homozygous fominant genotype (SS), 2/4 have heterozygous genotype (Ss) and 1/4 have homozygous recessive (ss) genotype. Since 1/4 offspring have ss genotype, they will die. Hence, the usual 1:2:1 ratio has been modified here to only 1:2:0
All of the following are examples of properties of water except bouyancy
Answer: Water
Explanation:
Though Cell membranes are selectively permeable to solute, cell membranes are permeable to water.
An osmotic pressure is exerted on cells when the osmolarity of their external environmental is more greater than their internal environmental.
When an osmotic pressure is exerted on cells for the cells to survive, water molecules move from the region of lower concentration to a region of higher concentration until there’s a balance in osmolarity.
Cell membranes are freely permeable to water.
Answer is water.
