West Nile virus (WNV) causes epidemics of febrile illness, meningitis, encephalitis, and flaccid paralysis. Since it was first detected in New York City in 1999, and through 2004, 16,000 WNV disease cases have been reported in the United States. Over the past 5 years, research on WNV disease has expanded rapidly. This review highlights new information regarding the virology, clinical manifestations, and pathology of WNV disease, which will provide a new platform for further research into diagnosis, treatment, and possible prevention of WNV through vaccination.

Answer:

0.09

Explanation:

let us define these events as

O = older

Y = younger

Prob(O) = 40% offspring x 25% chance of inheritance

= 0.4x0.25

= 0.1

P(Y') = 40% offspring x (1-25%) +(1-40%)x1

= 0.4x0.75 + 0.6x1

= 0.3+0.6

= 0.9 this is the probability of having the trait.

Probability that older offspring has trait but younger does not have it

Prob(O n Y') = prob(O) x Prob(Y')

= 0.1x0.9

= 0.09

Answer:

See the answer below

Explanation:

Null hypothesis: The two genes are independently assorting and therefore, are not linked to each other.

Let A represents the allele for tail length and B for fur color. Long-tail A is dominant over short tail a while brown fur B is dominant over white fur b.

For the first cross involving true-breeding mice:

    AABB   x   aabb

F1         AaBb (long tails and brown fur)

For the second cross:

      AaBb   x   aabb

4 AaBb - Long-tail, brown fur

4 Aabb - Long tail, white fur

4 aaBb - short tail, brown fur

4 aabb - short tail, white fur

Since the phenotypic ratio from the cross is 1:1:1:1, if the null hypothesis was to be true, it means that the expected phenotype ratio should be 1:1:1:1.

In order to test this hypothesis, we use Chi-square:

phenotype                           O            E                 X^2  

Long-tail, brown fur           118          97.5        [tex]\frac{(118-97.5)^2}{97.5}[/tex] = 4.31

Long tail, white fur              77           97.5             4.31

short tail, brown fur             81           97.5              2.79

short tail, white fur              114           97.5              2.79

Total                                                                          14.2

Degree of freedom = 4 - 1 = 3

Critical Chi-square value = 7.815

The calculated Chi-square value is more than the critical value, hence, the null hypothesis is rejected.

Explanation:

Comparative investigation involves the collection of data from different "subjects" (including organisms, object or characteristics) or obtaining data under different conditions (such as seasons, years or locations) for the purpose of comparison. This type of investigation is both time and capital intensive; meaning it requires a lot of time and money. It however provides a larger and wider range of data that might not be available through other "independent investigations" because a large amount of subjects is usually studied for proper and accurate comparisons.

Answer:

D- A comparative investigation can provide a wider range of data than can be obtained from the Internet.

Answer:

In food webs, arrows point from an organism that is eaten to the organism that eats it. As the food web above shows, some species can eat organisms from more than one trophic level.

Explanation:

Answer:

reproduction

population

phenotypes

phenotype

genotype

genotype

mutation

generation

Explanation:

Natural selection is differential reproduction among individuals,  in a population  due to differences in phenotypes, which are said to be adaptive.

Individuals with the adaptive phenotype have a reproductive advantage (increased reproductive fitness);  therefore, they contribute a disproportionately high number of progeny to the next genotype.

The adaptive genotype and the underlying mutation will increase in frequency in the generation over time.

While most plants reflect more green than any other in the visible spectrum, a relatively small percentage of green light is transmitted through or reflected by the leaves.The majority of green light is useful in photosynthesis.

Although green is the visible spectrum color that most plants reflect the most light from, only a small portion of green light.

It actually passes through or is reflected by the leaves. Most green light is beneficial for photosynthesis.

Thus, Plants, algae, and some microorganisms use the process of photosynthesis to convert sunlight into energy. Water and carbon dioxide (CO2) are chemically changed into food (sugars) and oxygen during the process.

The pigment chlorophyll, which gives plants their green colour, is frequently used in the chemical reaction.  Our planet's atmosphere is abundant in oxygen because of photosynthesis.

Thus, Although green is the visible spectrum color that most plants reflect the most light from, only a small portion of green light.

Explanation:

Answer and Explanation:

1. Each of the elements shown are transmitted to the fetus during pregnancy through the mother's bloodstream and through the umbilical cord, where the fetus receives all the support for its body, such as oxygen, nutrients, hormones, treatments, tests, among others. others. Some of them are possible through the visualization of the fetus and the manipulation of the products written by him.

2. Syphilis is a sexually transmitted infection caused by the bacteria Treponema pallidum. This infection has three phases (primary, secondary and tertiary) that are interspersed with asymptomatic periods, which aggravates the severity of the disease, since it presents itself as a silent evil. The primary phase occurs between 3-4 days after infection and its main symptom is the presence of wounds throughout the body, especially in the genitals. If not treated properly, 8 weeks later the secondary phase appears, where the infected person has red spots on the body, itching, fever, muscle pain and swollen and painful lymph nodes in the neck and armpit. When left untreated, the disease progresses to the tertiary stage where it presents severe symptoms that are difficult to diagnose. The disease affects the brain, eyes, heart, joints and the nervous system, causing severe headaches and even epilepsy.

3. It is necessary for both partners to be treated in case of any sexually transmitted infections. This must be done, primarily because the transmission occurred between these partners, which indicates that both have the disease and can reinfect themselves, or infect other people.

4. People aged 15 to 24 are at the greatest risk of being infected with a sexually transmitted infection. This is because people at this age are more likely to not get a steady partner and to adopt behaviors that facilitate infection such as having sexual contact without adequate protection.

5. What causes cervical cancer is the untreated infection of a virus called HPV. This type of cancer is usually asymptomatic, but in the early stages it may show bleeding from the genitals after sexual intercourse.

i think protein is the answer of this question.

The type of molecule which can be found in living things that lacks carbon atoms are water molecules. Thus, the correct option is D.

Water has the simple molecule which has mainly composed of two small, positively charged hydrogen atoms and one large negatively charged oxygen atom. When the hydrogen atoms bind to the oxygen atom, it creates an asymmetrical molecule with a positive charge on one side and a negative charge on the other side of the compound.

The biomolecules are the substances which are found inside the body of a living organism. Water molecules are the type of molecules which can be found in the living things which lacks carbon atoms.  

Therefore, The type of molecule which can be found in living things that lacks carbon atoms are water molecules. Thus, the correct option is D.

Answer:

12.5m/s^2

Explanation:

Acceleration of an object can be calculated by using the formula;

a = v-u/t

Where; a= acceleration

v= final speed

u= initial speed

t= time

According to this question, the flying object is moving at 150m/s, meaning that ∆V = (v-u) is 150m/s, where initial speed is 0m/s.

Since time is 12s, the acceleration is thus:

a = 150-0/12

a= 150/12

a= 12.5

Hence, the acceleration of the flying object is 12.5m/s^2
