Carbon dioxide is a colorless and non-flammable gas at normal temperature and pressure. Although much less abundant than nitrogen and oxygen in Earth's atmosphere, carbon dioxide is an important constituent of our planet's air. A molecule of carbon dioxide (CO2) is made up of one carbon atom and two oxygen atoms. Carbon dioxide is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas.
Answer:
They contain different genetic material.
Explanation:
DNA viruses contain DNA for genetic material while RNA viruses contain RNA. When RNA viruses enter a host cell, they must convert their RNA into DNA. DNA viruses change the biochemical functions in the nucleus for DNA replication and creates RNA that controls the proteins needed by the DNA virus (capsid).

Answer:
This question is incomplete, it is asking to fill in the missing gaps as follows:
The principle of dominance is a ______ inheritance pattern.
It’s states traits that are ______ mask the traits that are______
The answers to the missing gaps are: MENDELIAN, DOMINANT, RECESSIVE
Explanation:
Gregor Mendel proposed the principles that govern inheritance. These principles are called MENDELIAN inheritance pattern because they align with or follow the principles of Mendel. One of these principles by Mendel is the LAW OF DOMINANCE.
Mendel has previously stated that there are two alleles for each gene. Each contrasting allele encodes a different phenotype. However, the law of dominance states that one of these two alleles called DOMINANT allele has the ability to mask the phenotypic expression of the other allele called RECESSIVE allele. In other words, a dominant trait will mask the recessive trait.
For example, in a gene Tt, allele 'T' for tallness is dominant and hence, will mask the phenotypic expression of allele 't' for shortness. This means that the tall trait (dominant) will mask the short trait (recessive) as explained by Mendel's law of dominance.
Answer:
lymphocytes
Explanation:
In immune system, there are three main group of cells that is the response of our defenses.
Neutrophils are one group responsible to be the first response, they travel all around our body trough the stream blood and can detect the first signals of infection.
Monocytes and macrophages, are another group of cells that can "eat" the bacteria or viruses and destroy them when they are inside our body.
The third group, the lymphocytes, are conformed by three group of cells, T - cells (that help to destroy infected or cancerous cells), B- cells (responsible to produce antibodies, so they are the ones that conformed our second barrier of defense) and the NK cells ( natural killers, the ones to control several types of cancer and microbial infections).
Hope this info is useful.
