I believe they are positioned Beneath one of the clavicles. Pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate. Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of heartbeat.
Answer:
1/16
Explanation:
Sickle-cell disease is caused by a homozygous recessive genotype <em>dd</em>.
A man and a woman both heterozygous Dd will have the following offspring:
The probability of having a <em>dd</em> child with Sickle-cell disease is 1/4. Each time they have children the gamete combination is random, so the genotype of the second child is independent from the genotype of the first child.
According to rules of probability, if two events are independent from each other, the probability of both happening is calculated by multiplying the individual probabilities of each.
Therefore the probability of having the first two children with the disease is 1/4 x 1/4 = 1/16.
Answer:
Option B. Sequence the aniridia and eyeless DNA sequence and regulators.
Explanation:
DNA sequencing:
It is the method of determining the sequence of nucleic acid. DNA sequence includes the method to determine the order of nucleotide sequences. Through the process of sequencing aniridia and eyeless DNA are sequenced and analysed on Gel electrophoresis. Sequencing similarity shows evidence that the two genes are functionally equivalent.
Best choice:
B. Sequence the eyeless and aniridia DNA sequence and regulators.
Carbohydrates are an important type of FOOD MACRO MOLECULES.
Food macro molecules refers to the small chemical sub units of molecules which are found in food. There are four major food macro molecules, they are carbohydrates, proteins. lipids and nucleic acids.
Carbohydrate is an important source of fuel for the biological system.
