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 <em>Arthrobacter </em>includes Gram-positive bacteria
- <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
- <em>Staphylococcus spp.</em> are Gram-positive bacteria
- <em>Bacillus spp</em> are Gram-positive bacteria
- <em>Mycobacterium spp.</em> 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.

Hi , the answer is Africa , hominids have been found in South Africa.
Answer:
b. the number of motor units recruited
Explanation:
Recruitment of motor units is defined as the activation of several additional motor units which results into high contractile force in a muscle. A motor unit consists of the stimulating muscle fibres and one motor neuron.
Activation of motor neuron, stimulates and contracts all the muscle fibres inherited by the motor neuron. When only one motor neuron is activated, it results into a weak but distributed contraction of the muscle. Activating more motor neurons will result in activation of more muscle fibres, and thus a stronger muscle contraction.
Hence, the correct option is b.
Answer:
Yes
Explanation:
If both of the parents have a recessive trait that decides fur color, then there is a 25% chance that the offspring will receive the recessive traits from each parent and will not receive either of the dominant traits.
I would say C.
Dams don't use any chemical means to get their energy output, so B and D are out. A converts to potential energy which can't produce electricity without being set in motion, so it doesn't work. That leaves B, which makes sense. Potential energy to mechanical energy to electrical energy.
