<u>Answer</u>: A) They have been geographically isolated from each other for a longer time.
<u>Explanation</u>: An isthmus is defined as a narrow strip of land that separates two bodies of water as well as connecting two larger landmasses at the same time. Thus, an isthmus if an efficient physical barrier that has separated an original shrimp species. This has resulted in the extant deep-water shrimp species through the evolutionary process known as allopatric speciation.
The age of an isthmus is in the range of at least two million years. Thus, the two deep-water shrimp species have been separated from each other for a very long time.
Answer:
Explanation:
The amount of biomass that is produced in an area during a given time is referred to as primary production/productivity.
<h3>What is biomass?</h3>
- Renewable organic material obtained from plant and animal sources if referred to as biomass.
- Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
- Primary productivity is measured as biomass produced per unit area over a give time period
- It is usually expressed either in weight or energy.
- There are two ways to express primary productivity:
a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.
b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.

Naphthol AS-D chloroacetate esterase (specific) is usually positive in <u>Granulocytic</u> cells, and alpha naphthyl acetate esterase (nonspecific)is useful for identifying blast cells of <u>monocytic</u> lineage.
- White blood cells known as granulocytes have tiny granules. Proteins are present in these granules.
- Granulocytes can be classified as neutrophils, eosinophils, or basophils. The body uses granulocytes, particularly neutrophils, to fight bacterial infections.
- A monocyte is a subtype of phagocyte and a type of white blood cell.
- The role of the monocyte-macrophage cell lineage in acute and chronic allograft immunopathology is becoming more widely acknowledged.
- It is linked to lower graft performance and survival when this lineage of cells predominates in tissue that is rejecting an allograft.
