Answer:
Option A, The lymphocytes express antigens specific for the antibodies in the assay
Explanation:
The options for the question are
a) The lymphocytes express antigens specific for the antibodies in the assay
b) The lymphocytes do not have antigens specific for the antibodies in the assay
c) This is not a valid method for identifying HLA agents.
Solution -
The aim of conducting this assay is to use the ability of the microlymphocytotoxicity assay (CdL) to detect the antibodies specific to the antigens based on the complement dependent assay.
The B and T lymphocytes are tested at both warm and cold temperatures and then the result obtained is compared with other non –complement based test results. HLA-ABC alloantibodies are weak in reactivity and specific to B cell hence they can be identified only through the CdL assay.
Hence, option A is correct
The answer is B; global warming is an increase of the earth’s temperature due to the greenhouse emissions released that keeps the weather staying warm due to staying within the atmosphere
Bacteria recycle matter in an ecosystem through breaking down of the organic debris.
<h3>What is decomposition?</h3>
Decomposition is defined as the break down of dead organic matter in nature by microorganisms such as bacterias thereby releasing elements such as nitrogen that can be reused again.
Bacterias, protozoa and some fungi are known as decomposers in the food chain of an ecosystem which recycles elements found in dead organic matter by breaking them down.

Answer:
Volume of lead is 13.3cm3
Explanation:
Density is mass of a substance divided by volume.
The density of lead = mass÷ volume.
Mass is 150 grams.
Density is 11.3g/cm
11.3=150/volume.
Volume=150/11.3
Volume=13.3cm3.
