Which of the following statements about archaea are true cowan?A) They are prokaryotes.B) They lack peptidoglycan in their cell
Veseljchak [2.6K]

Answer:

All the options are true except option D.

Explanation:

Archaea are a group of prokaryotic organisms i.e. they lack a membrane bound nucleus. They are one of the the three domains of life (the other two being bacteria and eukarya). Archeans possess a cell wall like bacteria but it is not composed of peptidoglycan, like bacteria cell wall.

Archeans are generally known to be found in very severe environmental conditions, hence, they are referred to as extremophiles e.g Some are thermoacidophiles i.e. thrive in very hot and acidic environment while others are extreme halophiles i.e. thrive in salty regions. Archeans known as methanogens produce methane gas as a product of metabolism from carbon dioxide and hydrogen.

However, the domain archeae was only found to be in existence recently after the domain bacteria, hence, they are not considered to evolve before the domain bacteria.

a researcher wishes to know whether there is a significant difference in the number of knee injuries reported among four sports.
boyakko [2]

Answer:

Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.

Explanation:

The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.

<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>

To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.

JulsSmile [24]

Answer:

The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype
