7 0

Answer:

immediate hypersensitivity is a correct answer.

Explanation:

Allergy to pollen is classified as immediate hypersensitivity.

Immediate hypersensitivity is a type I hypersensitivity induced by an antigen called allergens like dust, pollen grains, etc.

Immediate hypersensitivity is a type of allergic reaction.

It occurs through the exposure to allergen by inhalation, through direct contact or by ingestion.

Thus Allergy to pollen is classified as immediate hypersensitivity and it  is IgE mediated allergic reaction.

Hershey and Chase used radioactive isotopes to label different parts of the phage. They grew one batch of phage in the presence
AlekseyPX

The sulphur would lable the capsule and the phosphorous the nucleic acid.

<h3><u>Explanation</u>:</h3>

Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.

This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.

(a) (1 pt) Assume diastolic blood pressure is normally distributed in a certain population, with a mean of 82 mmHg and a standar
Natali [406]

Answer:

2.275% of this population has a diastolic blood pressure less than 60 mmHg

Explanation:

Hello!

Yo have the distribution of the diastolic blood pressure in a certain population. Be X: diastolic blood pressure of an individual, X~N(μ;δ²)

Where

μ= 82mmHg

δ=11 mmHg

You need to calculate the probability of an individual of this population having less than 60mmHg diastolic blood pressure.

Symbolically:

P(X<60)

To obtain the value of probability you need to standardize the value of diastolic pressure so that you can obtain it from the standard normal distribution. The way to standardize the value is to subtract the mean and divide by the standard deviation

Z= (X-μ)/δ~N(0;1)

P(Z<(60-82)/11)

P(Z<-2)= 0.02275

I hope it helps!

kow [346]
Obligate symbiotic fungi that form associations with plants by entering their cortical cells without invading the plant cells membrane are called endomycorrhizae and include the genus Glomus. Many plants form associations called mycorrhizae with fungi that give them access to nutrients in the soil, protecting against disease and toxicities.  In these associations the fungi are integrated into the physical structure of the root, where the fungi colonize the living root tissue during active plant growth.
