Answer:

He is Wrong

Explanation:

When it comes to evolution and adaptation, geographically speaking speciation can occur all around the same habitat. when you consider gene pools, selective pressure, and genetic drifting. a species can become completely different even while living in the same place. Galapagos finches are a prime example of this. so are monkeys living in the amazon and sharks they live in the same place but are a geberally different species with different abilities.

The diagram below shows four different living organisms.
Gwar [14]

'All living organisms are composed of cells.' This is the part of the cell theory which is supported by the given pictures.

Explanation:

The cell theory were proposed by three scientists; T. Schwann, M.J. Scheleiden  and Rudolf Virchow.

The cell theory states :

  • Cells are basic structural and functional unit of life.
  • New cells arise from pre-existing cells.
  • All living organisms are made up of cells.

The given pictures are of different unicellular and multi-cellular organisms.

First picture shows a unicellular prokaryote and all the others  show a section of tissue which is made up of number of cells.

On observing the pictures we can get the idea that all living organisms are composed of one or more cell.

So we can conclude, the picture supports the fact that' All living organisms are made up of cells.'

Homework. Unanswered
Dennis_Churaev [7]

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:
  1. Actinomycetes are Gram-positive bacteria
  2. The genus <em>Arthrobacter </em>includes Gram-positive bacteria
  3. <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
  4. <em>Staphylococcus spp.</em> are Gram-positive bacteria
  5. <em>Bacillus spp</em> are Gram-positive bacteria
  6. <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.

In what stage does the skin blister allowing bacteria to enter the site of the pressure ulcer
dimaraw [331]
I think it is stage 2
At stage two, the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful. The sore expands into deeper layers of the skin. It may appear as a scrape, blister, or a shallow crater in the skin. At times this stage looks like a blister filled with clear liquid. Also at this stage some skin may be damaged beyond repair or may die.
