Answer:
Explanation:
Stage IV (stage 4 liver cancer): The cancer has spread to nearby lymph nodes and may have grown into nearby blood vessels or organs. Advanced liver cancer does not often metastasize (or travel to distant organs), but when it does, it is most likely to spread to the lungs and bones.
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.

How does Mr. G's altered blood flow explain his signs and symptoms? Drag and drop the appropriate labels into position to explain how this defect might cause Mr. G's other problems. Fill the boxes in order, starting with 1, then 2, etc

Answer:
- When left ventricles contracts, some blood goes up through mitral valve into the left atrium, Turbulent flow through the valve causes systolic murmur. the atrium is overfilled and dilated.
- Because some blood re-entered the mitral valve, less is pumped out into the aorta. the ejection fraction is only 43%
- Less blood enters aorta, so SBP is low. Baroreceptor reflex causes increased heart rate; wall of overworked left ventricles becomes thicker
- Because its already partly full of blood from the ventricle, the left atrium accepts less blood from the lungs, the lungs overfilled with fluid; resulting in troubled breathing.
Explanation:
A murmur is a result from a abnormal blood flow to the heart.Its basically an unusual sounds that is heard between heartbeat A systolic murmur occurs when the heart muscles contracts. i.e they begin and end between S1 and S2.
From the above information, it seems like Mr G is experiencing mitral regurgitation. It is a condition where mitral valve doesnt close tightly and as a result the blood flows back from the left ventricle into the left atrium.
