Answer:

Interstitial fluid

Explanation:

Otitis media is an acute infection of the middle ear. It is caused mainly by bacteria and is associated with nose and throat infections. The causative bacteria pass into the auditory tube from the nasopharynx and cause infection in the middle ear. There is a build-up of a large amount of fluid interstitial fluid in the tympanic cavity resulting in reddening and bulging of the eardrum.  

Children have almost horizontal auditory tubes that decrease drainage and therefore, are most likely to become affected. To treat the condition, a small tube is inserted into the eardrum to provide a pathway for the drainage of the fluid.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is
Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

    P   P

p   Pp Pp

p   Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp

Which of the following terms is used to describe the steady breeze of particles flowing out from the sun?
STALIN [3.7K]
<h2>Answer:</h2>

The term is <u>solar wind</u>.

<h2>Explanation:</h2>

The breezy particle which is produced from the corona region of the sun is called as Solar wind.  It is made up of electrons, protons and alpha particles with kinetic energy. Implanted inside the sunlight based breeze plasma is the interplanetary attractive field.  

The sun oriented breeze shifts in thickness, temperature and speed after some time as the sunlight changes. Its particles can get away from the Sun's gravity on account of their high vitality coming about because of the high temperature of the crown, which is caused due to source of origin called corona.

What is the probability that a seed from a parent plant of genotype Rr will carry the r gene
daser333 [38]
The answer is 50 percent.

Parent plant of genotype Rr will in meiosis produce haploid gametes which will carry either R allele or r allele. Since there are only two possibilities R or r, the probability that seed will get r gene is 1 of 2. This can be presented as 1/2, which is 50%.
