Explanation:
B. contains enzymes that begin the breakdown of proteins
C. moistens food and aids in compacting of the bolus
D. dissolves food chemicals so they can be tasted
Answers
Saliva is watery substance secreted by salivatory glands. It cleanses the mouth and maintenance oral hygiene. It moistens the food, so the created food bolus could easier pass into the esophagus. It also carries food chemicals to taste receptors so they can be tested. It contains enzymes involved in the food digestions. Some of them are amylase, which begins the breakdown of the starch, and lipase, which begins the breakdown of triglycerides. There are no enzymes in the saliva that break down proteins.
Final answer:
Saliva cleanses the mouth, moistens and compacts food, and dissolves food chemicals for taste.
Explanation:
Saliva is a clear liquid that is produced by the salivary glands in the mouth. It serves several important functions in the digestive process. It keeps the mouth clean by cleansing it and helps to remove food particles. Saliva moistens food and aids in the compacting of the food into a bolus, which can be easily swallowed. Additionally, saliva contains enzymes such as amylase that begin the breakdown of carbohydrates, not proteins. Lastly, saliva dissolves food chemicals so they can be tasted.

B. RNA polymerase will now bind to the coding region of the gene and carry out transcription.
C. RNA polymerase may not be able to bind to the DNA, so transcription will not occur
Answers
A scientist modified the structure of a promoter region of a gene. its effect on transcription and translation is that the RNA polymerase cannot bind on the promoter region, therefore no transcription will take place. As a result there will be no protein translation.
Answer: C) RNA polymerase may not be able to bind to the DNA, so transcription will not occur.
I hope it helps, Regards.

Both bacteria (which belong to the group of Prokaryotes) and Archaea have no nuclei but have cell walls. Those are groups of unicellular organisms. But, they differ in the makeup of their cell walls. Archaea have cell walls made of uncommon lipids while bacteria have cell walls made of peptidoglycan.
Bacteria and archaea differ in their cell walls makeup.
Further Explanation:
Archaea is considered to arise many years ago and is also considered to be the most primitive form of life. Earlier they were classified as bacteria but as they possessed certain difference features when compared with bacteria, it was now termed as archaea. Some of the characteristics of archaea resembles eukaryotes while other resembles with prokaryotes.
Archaea are single celled organism and they can thrive in harsh conditions like marshy area and hot springs. Some of the example of archaea are, Thermococcus litoralis, Methanopyrus kandleri, Cenarchaeum symbiosum etc.
The features of archaea which are similar to bacteria are:
1. Lack of nuclear envelop.
2. Lack of membrane bound envelop.
3. Presence of circular chromosomes.
The features of archaea which are similar to eukaryotes are:
1. Methionine is the initiator amino acid for protein synthesis.
2. Lack of peptidoglycan in their cell wall.
3. Association of histones with DNA.

Answer:
1. C
2. D
Explanation:
In an experiment, which aims at solving a particular problem or answering a scientific question about nature, the scientific method is employed. The scientific method contains the following steps:
- Making an observation.
- Asking a question.
- Formulating a hypothesis
- Testing the hypothesis via experimentation
- Analyzing the results
- Conclusion
According to question 1, the PURPOSE of an experiment portrays what is about to be done in a question format. For example, a purpose can go this: What will be the effect of pesticides on the growth of cowpea?. Furthermore, the PURPOSE helps make a research and state a hypothesis in the next step.
- In the analysis of result, the qualitative or quantitative approach is used. The QUANTITATIVE method involves the use of numbers or numerical data to express the outcome or result of the experiment. By counting or measuring, a numerical data is collected and given a unit depending on what is being measured
