Answer:
Option 3 and 4 are most likely correct
Explanation:
<em>Option 3</em>: We know that area 1 would contain heavy streaking and not single colonies. Therefore, if the loop crosses area 3 and enters area 1, it will definitely result in heavy streaking again.
<em>Option 4</em>: We always need to sterilize properly the loop when streaking in different areas. If we don't do it, it is possible that the loop contains a lot of bacteria that would be streaked again.
Options 1 and 2 are incorrect because, according to question, there is a uniform growth but no isolated colonies. So, contamination or mixed culture would not produce uniform growth streaking rather mixed with other bacterial types.
The correct term to fill in the blank would be peripheral. The two major divisions of the nervous system are the central and the peripheral nervous systems. The central nervous system consists of the spinal cord and the brain. The peripheral nervous system is made up of nerves and small amount of gray matter known as the ganglia. The nervous system is a very important part of the body as it is responsible of connecting all of the organs and the parts to the brain. It is responsible for carrying messages to the brain and out from the brain to the other parts of the body.
False, when more cells are made it is reproducing.
The question is incomplete and the complete question is
Which is false about the Tilia stem?
Answer:
C) The xylem is located outside the phloem
Explanation:
<em>Tilia americana</em> is a tree which grows in the climate of Eastern America. The tree is dicotyledonous and therefore posses secondary growth.
The anatomy of the stem of the Tilia plant shows that the:
1. Pith- the pith is the central portion of the stem which is composed of the parenchymatous cells. The pith also contains the mucilage ducts.
2. Cortex- the cortex is the portion present inside the epidermal layer which is made of both the chloroplast containing cells called collenchyma cells and the parenchyma.
3. Epidermis- The outermost layer which is composed of the single layer of cells.
4. Vascular bundle- Since the phloem is located inside the xylem and not xylem is inside the phloem therefore in the given is the false statement.
Thus, Option-C is correct.
British naturalist Charles Darwin is credited for the theory of natural selection. While he is indeed most famous, Alfred Wallace, simultaneously came to a similar conclusion and the two corresponded on the topic. change in heritable traits of a population over time.
Hope this helps!
