How does eating influence high density lipoproteins (HDL) in the body?
s344n2d4d5 [400]

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>

What is the equation for a photosynthesis???????????????​
Katarina [22]

The equation for photosynthesis is given as:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

<h3>Photosynthesis</h3>

Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.

Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.

During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

The equation for photosynthesis is given as:

6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

What do dna microarray assays allow scientists to study regarding gene expression?
Allisa [31]

DNA microarray assays allow scientists to identify networks of gene expression across an entire genome.

The microarray is scanned to determine the expression of each gene printed on the slide after hybridization. The associated spot on the microarray turns red if a particular gene's expression is higher in the experimental sample than in the reference sample.

The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2. The chip is made up of a tiny glass plate that is enclosed in plastic. A few businesses use techniques resembling those employed to create computer microchips to produce microarrays.

Explanation:

In the Sympathetic Nervous System PNS subdivision in which nerve injury would be the most dangerous for life.

 It is important for survival to fight or respond to flight because it controls the physiological reaction to a risk or danger and this flight and flight response is activated by sympathetic nervous system. This system is a part of automatic nervous system and operated by various interconnected  neuron
