Answer:
Both parents are heterozygous carriers.
Explanation:
Both parents are heterozygous carriers. Sickle Cell Anaemia is usually referred to as a recessive condition since an individual must have two copies of the sickle gene in order to have the disorder.
Since neither of the parents is ill, both of them must be heterozygous carriers for the child to have the disorder
II and III only. The fungus is a heterotroph, since it's not making it's own food, but it's also a Saprotroph (since it externally digests dead organic materials; saprotrophs are a special subset of heterotrophs).
Answer:
a) B b) D c) A
Explanation:
Alleles exhibit dominance over each other leading to the dominant one being express and the recessive one not expressed. Alleles are variants (different) genes that codes for a specific trait.
At Anaphase 1 homologous chromosomes separate leading to each being pulled to the opposite pole and the sister chromatids remain together while the homologs experience segregation.
Dominant trait is the one that is expressed. It usually exercise dominance over recessive trait until it is removed from the recessive trait and replaced with another recessive gene before it is expressed.
The cell interior would experience higher than normal Na⁺ concentrations and lower than normal K⁺ concentrations.
<h3><u>Explanation</u>:</h3>
The membranes that contain high concentration of sodium potassium ATPase pumps are generally the excitable membranes. These are found in muscles and in neurons.
In normal scenario, the de polarised membrane has higher potassium concentration inside and higher sodium concentration outside it. Now as an impulse comes, the sodium channels open which creates sodium influx and then potassium channels open which let's potassium efflux. Then after the conduction of impulse is over, the membrane regains its de polarised state by the sodium potassium ATPase pumps which transfers three potassium outside the cell and two potassium inside the cell in exchange of an ATP.
Now if the ATP is non hydrolyzable, then the pump won't occur. This will lead to greater sodium inside the cell and greater potassium outside the cell but the change difference will be nil on both sides.
