Answer:
C
Explanation:
This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).
N.B: let F represent the gene involved.
A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.
A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.
The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff
The resulting four offsprings will
be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1
Answer:
repolarization
Explanation:
Potassium channel blockers are drugs that interfere with the flow of potassium ions (K+) through potassium channels in cell membranes, thereby prolonging the duration of the action potential (repolarization phase). For example, amiodarone is a class III antiarrhythmic agent whose target is HERG human cardiac K+ channel. This drug (amiodarone) acts by prolonging the repolarization phase of the cardiac action potential.
Answer:
Starch is made up of a mixture of amylopectin and amylose and is the stored form of sugar in plants. Monosaccharides are simple sugars whereas cellulose and starch are not. Cellulose and starch contain many sugars and are polysaccharides. Also, lipids are not carbohydrates.
Explanation:
Let’s say you own a business and you have facial products
Positive feedback is information or a persons reaction, when someone speaks good about your business’s product and customer service.. etc
Negative feedback would be someone saying your products aren’t so good and don’t work, or just getting a bad reaction from them etc
I really hope this helps <3 if not I’m sorry just try and put it in different words that you understand
