All of the following are true of Influenza A except:O Influenza A is a virus that has a rapid rate of mutation O. Vaccination requires use of an injection of an inactivated vaccine O. Mass production of a vaccine requires several months O The success of vaccination is highly dependent on the match of the vaccine with the current strain of Influenza
The correct answer is B) Vaccination requires use of an injection of an inactivated vaccine. Influenza A is a virus that has a rapid rate of mutation, and mass production of a vaccine requires several months.
However, vaccination is usually done with a live attenuated vaccine, which consists of a weakened version of the virus, rather than an inactivated vaccine. The success of vaccination is highly dependent on the match of the vaccine with the current strain of Influenza.
Vaccination against influenza is an important public health measure to reduce the rate of infection and reduce the severity of symptoms in those who do become infected.

Consumers rely less on price to judge the quality of a product when they have prior experience with the product.
Consumers who use price as a proxy for quality do so because they believe there are differences in quality. It's natural to like brands and products that are unique. When prices are low, small changes in price correspond to large changes in quality. At higher prices, small price changes correspond to small quality changes. However, in all cases, the higher the price, the higher the quality level.
If a product brand is qualitatively superior to its competitors, the price should also be higher. Conversely, a higher priced product is also a higher quality product. Therefore, price should be a good indicator of product quality.

Tay-Sachs disease is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. The most common form of Tay-Sachs disease becomes apparent in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when their development slows and muscles used for movement weaken. Affected infants lose motor skills such as turning over, sitting, and crawling. They also develop an exaggerated startle reaction to loud noises. As the disease progresses, children with Tay-Sachs disease experience seizures, vision and hearing loss, intellectual disability, and paralysis. Children with this severe infantile form of Tay-Sachs disease usually live only into early childhood.
Tay-Sachs disease has been identified in the HEXA gene. One of the known mutations can eliminate the activity of the enzyme, which prevents the enzyme from breaking down a fatty substance. As a result, this substance builds up to toxic levels, particularly in nerve cells in the brain and spinal cord. Progressive damage caused by the buildup of the fatty substance leads to the destruction of these cells, which causes the signs and symptoms of Tay-Sachs disease
Riley was diagnosed with Tay-sachs, which he inherited from both his parents. Riley received a mutated copy of the gene from his mom and a mutated copy from his dad. Neither of his parents has Tay Sachs disease. You must have two copies of the mutated gene in order to develop Tay Sachs disease.

What effect did the inherited mutated genes have on Riley at the cellular level?
Is this mutation beneficial, harmful, or neutral to Riley? Defend your answer.
Is this mutation physically beneficial, harmful, or neutral to Riley's parents? Defend your answer.

What is Tay Sachs disease?When a child inherits a defect (mutation) in the HEXA gene from both parents, the condition takes place. The enzyme beta-hexosaminidase A is deficient as a result of the genetic mutation that causes Tay-Sachs disease.
The fatty compound GM2 ganglioside must be broken down in order for this enzyme to function. The brain and spinal cord's nerve cells are harmed by the accumulation of fatty substances.
A rare genetic illness called Tay-Sachs is inherited from one parent to the next. It results from the lack of an enzyme that aids in the breakdown of fatty compounds.

Origin of mitochondria and chloroplasts
How did mitochondria and chloroplasts most likely arise?
Multiple Choice
O They budded off from other organelles like the endoplasmic reticulum.
O They arose from viruses that were engulfed and became incorporated into the cell.
O They arose from bacteria that were engulfed and not digested
O They arose spontaneously from compounds within the cells.
Mitochondria and chloroplasts most likely arise from bacteria that were engulfed and not digested.
It is possible that swallowed prokaryotes, which formerly existed as autonomous entities, gave rise to mitochondria and chloroplasts. The endosymbiotic interaction between the host eukaryote and the aerobic prokaryote, which eventually developed into a mitochondrion, began when an aerobic prokaryote was swallowed by a eukaryotic cell. Photosynthetic prokaryotes were subsequently swallowed by eukaryotic cells with mitochondria, which later developed into specialized chloroplast organelles.
According to the endosymbiotic idea, mitochondria and chloroplasts were originally single-celled creatures that were devoured by further single-celled species. Numerous facts support this, such as the fact that both mitochondria and chloroplasts preserve their own DNA. Additionally, they frequently contain an additional membrane surrounding them, which may have been left over during endocytosis, in which the cell encircled the object in attempt to get it inside.

In this regard, it has been shown that the frequency of Rh + and Rh - blood types are 93% and 7%, respectively (in this case 85%).

all water found on earth cannot be used for drinking why ?( give reason)
Answer:
Explanation:
Because much of the water on Earth is polluted or otherwise unfit for human consumption, not all of it can be utilized for drinking. The following are some of the reasons why water may not be safe to drink:
1. Pollution: Many bodies of water, such as lakes and rivers, are contaminated by industrial and agricultural waste, sewage, and other hazardous substances. This can render water dangerous to drink and damage aquatic life.
2. Microorganisms: Many bodies of water contain hazardous microorganisms such as bacteria, viruses, and parasites that, if consumed, can cause sickness.
3. Salinity: Some bodies of water, such as the ocean, contain excessive amounts of salt and other minerals, making them dangerous to drink.
4. Chemical contamination: Groundwater can be contaminated by chemicals such as pesticides, heavy metals and other pollutants that can leach into the water supply.
5. Temperature: Some bodies of water are too hot or too cold to be used for drinking.
Water must be treated before it can be consumed safely. Treatment methods include filtration, disinfection, and removal of dissolved minerals. Therefore, not all water found on Earth is safe to drink, and it must be treated before it can be consumed.
All water found on Earth cannot be used for drinking because it is not always safe or clean.
