Answer:
The genes that the child inherited from the parents is the SS gene
Explanation:
The genetic composition of the haemoglobin genotype is given by two gene variants; A which is dominant and S which is recessive. As such, an individual can be AA, AS or SS. Individuals that are AA and AS do not show traits of the disease, but SS individuals have sickle cell anaemia.
From this example, since both parents have no symptoms and their child have sickle cell, their genotypes most likely were AS and AS. Let me show you how:
A S
A AA AS
S AS SS
From the cross above, there is a 1 in 4 chance that if both parents were AS, their child will be SS. Any other composition from the parents will not produce an SS offspring. Hence the genes that the child inherited from the parents is the SS gene.
I think the best phrase to describe this would be Founder effects. Founder effects occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have; a non-random sample of genes in the original population. Reduced variation from the original population.. According to Bottlenecks and founder effects, genetic drift can cause big losses of genetic variation for small populations.
Nucleolus is not connected to the nucleus via nuclear pores.
<span>Nuclear pores are protein complexes that cross double membrane of the nucleus and allow the transport of molecules across the nuclear envelope (double membrane): from the nucleus to the cytoplasm (RNA and ribosomal proteins) and into the nucleus (proteins, carbohydrates, signalling molecules and lipids).</span>
Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
