Answer:
d
Explanation:
organisms are made up of cells
Answer:
The following are the two functions of citric acid in the feta cheese:
1. Coagulation, that is, the chemical reaction of citric acid with proteins in milk leads to separation of curd and whey.
2. The citric acid functions as a chelating agent, which is required for syneresis, that is, for controlling the moisture content.
The following are the two functions of agar in the feta cheese:
1. Feta means to slice, and agar offers sliceable texture to the feta cheese as it produces a solid gel-like composition.
2. It is a vegetarian alternative for gelatin and exhibits higher gelling properties.
Answer:
DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.
Explanation:
DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.
It would be B. the mixture became warm, as a change in temperature is certain evidence that a chemical reaction has taken place.
