Answer:

Option C, single-blind study

Explanation:

In a single blind study, the researcher is aware of the experimental group in which the subject is placed. However, the subject is unaware of its placement. Such kinds of experiments are conducted to reduce the risk of errors or variation in participant’s response, if they come to know the group type in which they are placed.  

In a double blind study both the researcher and the subject of the experiment are unaware of the groups in which the subject is placed while conducting the experiment

Hence, option C is correct

Appears to contain a multilobed nucleus. what is the most likely identity of the observed leukocyte?
Brrunno [24]

Neutrophil is the most likely identity of the observed leukocyte

<h3>What is Neutrophil ?</h3>

The most common type of granulocyte in humans are neutrophils, also known as neutrocytes or heterophils, which make up between 40% and 70% of all white blood cells. They are an essential part of the innate immune system, and they have different functions depending on the species.

The bone marrow-produced stem cells are differentiated into the neutrophil-killer and neutrophil-cager subpopulations. Due to their potential ability to access tissues that other cells or substances cannot, they have a limited lifespan and are very migratory. There are two different types of neutrophils: banded and segmented neutrophils (or bands). They belong to the same family of cells as basophils and eosinophils, which is known as PMNs.

Conventionally pasteurized milk is sterile.<br> a. True<br> b. False
spin [16.1K]

Answer: False

Explanation:

Conventionally pasteurized milk is not sterile it gets sterile after it is homogenized. The process of pasteurization involves sudden heating and sudden cowling of milk which does not kills all the microorganism but is intended to kill some of the bacteria and inactivates some enzyme.

Homogenization is a completely separate process  which involve mechanical breakdown of fat molecules in the milk which increases the shelf life of milk by preventing the cream from rising at the top.

Hence, the given statement is False.
