Organisms compete for the resources they need to survive- air, water, food, and space. In areas where these are sufficient, organisms live in comfortable co-existence, and in areas where resources are abundant, the ecosystem boasts high species richness (diversity).

Answer:</h2>
I believe the correct answer is FALSE.
<h2>
Explanation:</h2>
Innate immunity is a fast acting response to confront a pathogen but does not keep memory. It is initiated and carried out by cell and can be refered to as cellular immunity lasting for a short term.
<h2>Further Explanation:</h2><h3>Innate Immunity:</h3>
This is the first line of defence and involves only cells. It lasts for a short period usually around 12 hours. It includes physical barries. The cells involved are: epithelial cells, dendritic cells, plasma proteins and natural killer cells. All the cells involved are macrocytes. It functions to recognize and attack the pathogen before the second type of immunity called adaptive immunity sets in. It usually is also non specific and responds generally to any pathogen.
<h3>Adaptive Immunity:</h3>
It is a much more longer lasting type of immunities and has memory. It has a combination of cells and humoral components. It involves Naive B cells which are triggered to release antibodies known as Immunoglobulins depending on the cause of the trigger. Immunoglobulins include IgG, IgM, IgA, IgG and IgD and are usually Y-shaped. Additionally, it involves Naive T cells that are activated into Effector T-cells to assist in fighting the pathogen. This type of immunity is more focused and specific antibodies are released for specific infections/pathogens. It lasts up to 5 days or longer depending on the pathogen. It also takes time to mount up and produce a response.

Answer:
0.033
Explanation:
Tay–Sachs disease is an autosomal recessive disorder. The possible genotypes and phenotypes are:
- TT = normal
- Tt = carrier
- tt = Tay-Sachs disease
I will use <em>p </em>to call the frequency of the dominant <em>T</em> allele, and <em>q</em> the frequency of the recessive <em>t</em> allele.
If the population is in equilibrium, the frequency of the tt genotype is q².
The frequency of the Tt genotype is 2pq.
The Tay–Sachs carrier frequency will be 0.033
Answer;
-All of the above,
Genetic research and testing includes; the Human Genome Project, gene therapy
, and genetically engineering drugs.
Explanation;
-Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder.
- Genetic research is the study of human DNA to find out what genes and environmental factors contribute to diseases. It is concerned with the study of the role of genes in traits such as the development of disease. It has a key role in identifying potential targets for therapeutic intervention and also in understanding genetically based variations in response to therapeutic interventions.
