Answer:

Genetic engineering: uses technology to alter or change an organism's genes

Cloning: Cloning is the process of using egg cells from an individual to produce a new organism.

Artificial selection: also called selective breeding, selects organisms with desired traits to breed, producing offspring with the desired characteristics.

Artificial selection: I is the process of breeding of plants and animals to obtain a needed characteristics in the offspring developed. The offspring developed have better immunity and faster growth. Genetic engineering: It is the process of transferring the characteristics that is DNA from one breed to another which are already present in the species and it is the fastest way of doing it. The offspring are less genetic defects as they can be bred from a healthy species. Cloning: This is the process of making the offspring an exact copy of species it is developed from. The parent and the offspring have the same DNA.

Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.

All bacteria indicated in the question can be classified by the Gram staining test:

Actinomycetes are Gram-positive bacteria
The genus Arthrobacter includes Gram-positive bacteria
Escherichia coli (E. coli) is a Gram-negative bacterium
Staphylococcus spp. are Gram-positive bacteria
Bacillus spp are Gram-positive bacteria
Mycobacterium spp. are Gram-positive bacteria

Prokaryotes can be divided into two domains: Bacteria and Archaea.

Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.

In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).

Archaebacteria belong to the Archaea domain.

Answer:

Fever c) is regulated by chemicals that reset the body's thermostat to a higher setting

Explanation:

Fever is a high body temperature and is one of the ways our immune system attempts to combat an infection. It is also referred to as pyrexia and it could be more than between 37.2 and 38.3 °C (99.0 and 100.9 °F) in humans, there is not a single agreed-upon upper limit. Temperature is regulated in the hypothalamus. Fever helps your immune system fight infections by speeding up the functioning of cells and it makes it harder for bacteria and viruses to thrive in the body.
