Answer:
The G-note's wavelength is longer.
Explanation:
As we know that
The relationship between frequency, wavelength and the speed given as
Speed = Frequency x Wavelength
V= f λ
For constant speed, if wavelength increase then the frequency of the sound get reduce.
The wavelength of the A-note sound waves is smaller than the G -notes sound waves.
Therefore the answer of the given question will be A.
Answer: The element with the greatest influence on cholesterol levels is the fat content of food. Not only the amount of cholesterol, but also the type of fat.
Explanation:
Cholesterol is a type of fat found in the body, which is used to make hormones and vitamin D. The liver makes cholesterol to handle these tasks, but cholesterol can also be incorporated into the body through foods such as meat, dairy, and poultry. If you consume a lot of these, the cholesterol levels could become too high.
There are two types of cholesterol:
- High-density lipoprotein (HDL) or “good cholesterol”. It transports the excess of cholesterol to be expelled so<u> it wont end up in the arteries. </u>
- Low-density lipoprotein (LDL) or “bad cholesterol”.<u> It transports cholesterol to the arteries, where it may collect in artery walls.</u> This could lead to a buildup of plaque known as atherosclerosis which can increase the risk of blood clots and if one of them breaks away and blocks an artery, it could cause a stroke or heart attack.
If there is a predominance of saturated fatty acids in the fat of the diet, a rise in serum cholesterol and LDL-cholesterol is caused. To lower the bad cholesterol, you should limit foods such as milk fats, fatty meats or sausage and include more fibre in your diet. On the other hand, <u>polyunsaturated fatty acids - for example, those present in seed oils or fish - produce their reduction. Monounsaturated fatty acids, such as those provided by olive oil, act like polyunsaturated ones and, in addition, tend to raise HDL-cholesterol, so their use entails a greater benefit.</u>
Answer:
they need a high ‘surface to volume’ ratio, which is good for exchanging materials between the inside and outside of cells. But this is probably not really the size-limiting reason, since cells vary enormously in size and surface area to volume ratios.
Explanation:
Answer:
The "short tail" dominant allele is easier to eliminate by selective breeding.
Explanation:
The only way for a recessive allele to be expressed (be visible) is when it appears as recessive homozygotic. These means the organisms need to have 2 copies of the gene. Selective breeding is based on the characteristics that one can see, so if the organism shows the "dilute" phenotype you can keep reproducing this individuals and get rid of the dominant allele.
On the other hand if you have a population with the dominant phenotype, you discard all the ones that have a recessive trait and you breed the dominant phenotype you could still get individuals with the recessive phenotype and individuals that express the dominant phenotype but are heterozygous.
