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.

A hole is made in an opaque sheet of paper. A monochromatic variety of light is shot at the paper from one side. On the opposite side of the paper, the effects of diffraction will be greatest when the light has a _______ and the hole is _______. A. long wavelength; small B. high frequency; small C. low frequency; large D. short wavelength; large
Answer:
THANK ME its B on usa testprep
Explanation:
A. long wavelength; small
Diffraction is the greatest whenever the gap where the wave is passing through is smaller. This gap property will make the wave to "curve" reaching a more wider area, the smallest the gap is, more the wave will curve, spreading more widely. The light would propagate more rather then being concentrated on one focus. The wavelength is also something that affects diffraction. Whenever the wavelength is longer, the wave will have more time to spread sideways after diffraction.

The diagram shows one process during sexual reproduction. After fertilization, the zygote contains 28 chromosomes. What is the number of chromosomes (n) present in the gametes?
A) 7
B) 14
C) 28
D) 56
Answer:
The correct answer would be B) 14.
In sexual reproduction, gametes are haploid cells formed after meiotic division of germ cells.
Meiosis is a cell division which results in the formation of four daughter cells from a single parent or germ cell. Each daughter cell contains half the number of chromosome present in the parent cell.
The haploid gametes fuse to form diploid zygote that is, the fertilization restored the diploid chromosomal number.
Now, the number of chromosomes in the zygote is 28. Thus, the number of chromosomes in gametes must be half of 28 that is, 14.

In a 10 m2 ecosystem, there are 20 raccoons. The population density of raccoons is _____. 2 per m2 4 per m2 10 per m2 20 per m2
Answer:
The correct answer is option A, [tex]2\frac{Racoons}{m^2}\\[/tex]
Explanation:
The Population density of any species in an ecosystem is equal to the number of that species living in one unit of area.
Therefore, population density can be represented as
[tex]\frac{Total population }{Total area of habitat} \\[/tex]
Substituting the given values in above equation, we get -
[tex]= \frac{20}{10} \frac{Racoons}{m^2}\\= 2 \frac{Racoons}{m^2}\\[/tex]
Which of the following statements is true about catalysts? (1 point)
A. Catalysts slow down the rate of chemical reactions.
B. All catalysts are enzymes
C. Catalysts are used up during a chemical reaction.
D. Catalysts lower the activation energy of a chemical reaction.
Answer:
The correct answer is: C. Catalysts are used up during a chemical reaction.
Explanation:
Catalysts are substances used in chemical reactions to speed them up. Many of our bodily functions require the use of catalysts to function at the rate we need them. The catalyst is not consumed during the reaction - because of this, catalysts can be re-used.
Catalysis is possible thanks to the presence of catalysts. Catalysts provide alternate pathways with the lower activation energy for the chemical reactions. Activation energy refers to the energy required for a reaction to happen. When there are no catalysts around, the activation energy is much higher, and thus the reaction is harder to achieve.
Catalysts in the body are called enzymes. Outside our bodies, there are also many catalysts, like heterogeneous catalysts, homogeneous catalysts, and photocatalysts.

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.

Which functional group is present in amine compounds?
A. COOH group
B. OH group
C. NH2 group
Final answer:
The functional group present in amine compounds is the NH2 group or amine group, which is the characterizing feature of an amine. The correct answer from the options provided is C.
Explanation:
The functional group present in amine compounds is the NH2 group. An amine is derived from ammonia, where one or more hydrogen atoms are replaced by hydrocarbon groups. In the context of amino acids, each molecule contains both an amine group (-NH2) and a carboxyl group (-COOH). While the amine group is a basic functional group with the formula -NH2, the carboxyl group is acidic and characterized by a carbon-oxygen bond and an OH group attached to the same carbon atom. In physiological conditions, the amine exists as an ammonium ion after gaining a proton, forming -NH3+ and the carboxyl group loses its proton to become a carboxylate ion -COO-.
