The researcher could look for the presence of proteins, because viruses have a envelope (capsid) composed of proteins that involve their genetic material. The capsid may have a helical or icosahedral structure and is extremely regular. Viroids cannot synthesize any type of protein, so differentiation is possible.
Hello. The chart mentioned in the question above is attached just below.
Answer:
A) has increased with increasing human population
Explanation:
As you can see in the graph below, the line that indicates the number of endangered species increases as the line that represents the increase in the human population increases. This means that the number of extinct species has increased with the increase in the human population.
This is because with the increase in the human population, there is a growing need for natural resources, in addition to increasing the need for cities to expand. All of this results in greater deforestation and extraction of natural resources, which ends up causing an increase in the factors responsible for the extinction of animals.

Answer:</h2><h2>Human blood grouping is mainly based on the antigens present on their RBC (red blood cells) and in plasma into various groups but the main antigens are namely A/B and Rh antigens.</h2><h2 /><h2>Depending on A/B antigens humans are grouped (ABO Grouping) into</h2><h2 /><h2>A group: those having A named antigen on their RBC.</h2><h2 /><h2>B group: those having B Antigen on their RBC.</h2><h2 /><h2>AB group : Those having both A B antigens on their RBC.</h2><h2 /><h2>O group: those having no antigens on their RBC.</h2><h2 /><h2>Depending on the presence of Rh antigens they are grouped into Rh positive or negative group.</h2><h2 /><h2>So if the person has both A and Rh antigens then he will be A positive blood group. But having only A antigen but not Rh Antigen then he will be A negative group.</h2>
<h2>Extra Information:</h2><h2>In addiition to these there is also the HH group. The peculiarity is that they do not express the H antigen. As a result they cannot form A antigens or B antigens on their red blood cells. Thus they can donate blood to anybody with ABO grouping but can receive blood only from Bombay blood group people.</h2><h2 />
Answer:
A and B are the answers.
Explanation:
Believe me I took a test a while ago with this question
Duyen has Hepatitis B. Hepatitis B contaminates in excess of 300 million individuals worldwide and is a typical reason for a liver ailment and liver tumor. HBV, an individual from the Hepadnaviridae family, is a little DNA infection with uncommon highlights like retroviruses.
At the point when the viral DNA polymerase is utilized to interpret RNA to DNA, it is going about as a switch transcriptase like that found in retroviruses. Actually, Hepatitis B infection's DNA polymerase and retroviral turn around transcriptase are fundamentally the same as and may have developed from a typical progenitor.
