If an individual is a carrier of an infectious disease, he is __________. if an individual is a carrier of an infectious disease, he is __________. both symptomatic and noninfective infective both asymptomatic and infective asymptomatic
An individual who is a carrier of an infectious disease is both asymptomatic and infective. This means they do not show symptoms, but can still transfer the disease to others, often via direct or indirect transmission mechanisms. Thus, carriers play a significant role in the propagation of infectious diseases.
Explanation:If an individual is a carrier of an infectious disease, he is both asymptomatic and infective. This means that while they do not show any symptoms of the disease, they can still transmit the disease to others. A good example is the herpes simplex virus, which may not present any noticeable signs or symptoms in most infected individuals.
Disease spreading in this way is referred to as a propagated spread, essentially progressing from person to person through a population of susceptible individuals. This can happen directly, with close person-to-person contact, or indirectly, via contaminated objects or surfaces, airborne inhalation of droplets or aerosols, or even through a vector such as an insect. Despite being asymptomatic, a carrier can have a major role in the spread of infectious diseases.
While a 'carrier' can also refer to an individual who can transmit a recessive genetic disorder to offspring without showing any symptoms, in the context of an infectious disease, a carrier is an infected individual who can transmit the contagious pathogen to others, whether or not symptoms are currently present.

What does set point theory suggest about the probable results of bariatric surgery?
Set point theory proposes that the body has a natural weight "set point" that it strives to maintain, and bariatric surgery, while effective for initial weight loss, may be met with resistance from the body's homeostatic mechanisms, potentially leading to weight regain over time.
According to the set point theory, the body aims to stay within a preferred or stable weight range. Due to restricted food intake or malabsorption, people who have bariatric surgery can initially lose a lot of weight. However, the natural defenses of the body may prevent long-term weight loss.
Increased hunger, decreased energy expenditure, and adaptations that make long-term weight loss difficult to maintain can all be caused by metabolic and hormonal changes. In order to prevent weight gain and address the body's set point processes, people may need to significantly alter their lifestyles, get continuing assistance, and consider other options in addition to bariatric surgery.

What information did scientists use when developing the geologic timescale?
Scientists studied the fossil record. They found four major changes in life forms. These four major changes were used to mark when one geologic era ended and the next began.
Scientists developing the geologic timescale used information from stratigraphy, biostratigraphy, and radiometric dating methods derived from the study of Earth's rocks and fossils.
Explanation:Scientists developing the
geologic timescale
used several different types of information, primarily derived from the study of Earth's rocks and fossils. They utilized information from
stratigraphy
, a branch of geology that studies rock layers, to understand the sequence of geological events.
Another crucial type of information was about fossil records. By studying the changes in the types of fossils found in different rock layers, they could develop a relative timeline of life on Earth. This is a concept known as biostratigraphy.
Furthermore, absolute dates of rock layers were obtained through radiometric dating methods, which estimate the age of rocks based on the decay of radioactive elements inside them. This provided numerical ages to correlate with the relative timeline from stratigraphy and biostratigraphy.

The relation between amino acid and polypeptide is similar to the relation between ________.
The relation between amino acid and polypeptide is similar to the relation between NUCLEOTIDE and NUCLEIC ACID.
The primary structure of the polypeptide chain is composed of 20 different classes of amino acids held together by peptide bonds.Thus, amino acids represent the building blocks of polypeptides (i.e., proteins).In a similar way, nucleotides are building blocks of nucleic acids (both DNA and RNA).On the other hand, monosaccharides (e.g., glucose) are building blocks of polysaccharides (e.g., starch).In conclusion, the relation between amino acid and polypeptide is similar to the relation between NUCLEOTIDE and NUCLEIC ACID.

The relation between amino acid and polypeptide is similar a leading to a longer chain.
Explanation:The relation between amino acid and polypeptide is similar to the relation between monosaccharide and polysaccharide in carbohydrates. Just like amino acids are the building blocks of polypeptides, monosaccharides are the building blocks of polysaccharides. Both amino acids and monosaccharides can link together through specific bonds to form longer chains.

Why is it important that nadp+ reductase is on the stromal side of the thylakoid membrane?
The NADP+ reductase is present on the outer side of the thylakoid membrane so as to release NADPH on the stromal side where it can be used during dark reaction along with ATP to form glucose.
Further Explanation:
The light reaction or energy-producing phase of photosynthesis takes place in the thylakoid membrane forming ATP and NADPH. These molecules are then utilized during the dark reaction to produce sugars that occur in the stroma. The ATP is the energy-storing molecule while NADPH is the reduced electron carrier.
NADP+ reductase or ferredoxin NADP+ reductase (FNR) is an enzyme that catalyzes the last step of the light reaction during photosynthesis that is the transfer of electrons from ferredoxin (reduced) to NADP+ and results in the formation of NADPH and ferredoxin (oxidized). This enzyme is located on the outer periphery of the thylakoid membrane. When FNR accepts electrons from ferredoxin it releases NADPH on the outside of the thylakoid membrane or the stroma as FNR faces outwards. NADPH cycling is a vital step and can occur only in the presence of light. The stromal side provides optimal light for the reaction to take place.
The ATP is also formed in the light reaction as the movement of electrons from one carrier to another releasing some sort of energy which is used to pump proton (H+) to the lumen from the stroma. The transfer of protons back to the stroma takes place through ATP synthase resulting in the formation of ATP.The ATP and NADPH are formed on the stromal side and are used in the dark reaction to proceed photosynthesis further and form a glucose molecule from carbon dioxide.
Therefore, the presence of NADP+ reductase on the stromal side is important so as to form NADPH on the outer side and perform the NADPH cycling efficiently.

After 3 hours of exercise, what are the main sources of energy?
After 3 hours of exercise, the body primarily uses fatty acids and ketone bodies for energy. Muscle glycogen is used up quickly, followed by blood glucose and increased fat metabolism. If exercise continues for extended periods, protein can also be broken down for glucose.
Explanation:After 3 hours of exercise, the main sources of energy for the body are fatty acids and ketone bodies. When muscle glycogen stores are depleted, which happens within the first few minutes of high-intensity exercise, the body then transitions to using blood glucose and fatty acids as the primary sources of energy.
Glucose can still contribute to energy production through the bloodstream, particularly if it's been recently ingested through diet. If exercise continues for an extended period or at lower intensity, fatty acid metabolism increases, and the body begins to utilize these fats more predominantly. Eventually, if the body is subjected to starvation or continued long-duration exercise, it will start producing ketone bodies from fatty acids as an alternative energy source.
Proteins are usually conserved during exercise but can be broken down to glucose in situations of energy deficit or extended duration activities. In summary, following exhaustive exercises like those spanning 3 hours, fat stores and any circulating blood glucose become the principal sources of energy for the body, with ketone body production coming into play thereafter.
