Which labeled viral structure in the diagram above stores viral DNA similarly to the way the nucleus
stores cellular DNA?
F. 3
G. 1
H. 4
J. 2
Answer:
4?
Explanation:
The labeled viral structure in the diagram above stores viral DNA in the head (number 4) similarly to the way the nucleus stores cellular DNA.
A virus is a term to refer to a microscopic particle characterized by infectious genetic information (DNA) that reproduces once it infects the host's cells.
The image shows the structure of a complex virus, it has the following parts:
Head (number 4)Collar (number 3)Tail (number 2)Long-Tail fiber (number 1)In the head, it stores the genetic information that is later transmitted to the cells of the host it infects. Likewise, it uses its cells to multiply. So the correct answer is 4.

e. coli are grown on a medium containing lactose. once glucose is added to the medium, the bacteria stop fermenting lactose
The lac operon is an operon required for the transport and metabolism of lactose in E.coli. When lactose is introduced to the increased medium, the lac genes are expressed due to the fact allolactose binds to the Lac repressor protein and maintains it from binding to the lac operator. Allolactose is an isomer of lactose. Small quantities of allolactose are shaped when lactose enters into E. coli. allolactose binds to the repressor protein and reasons the conformational change. As a result of this, the repressor can no longer bind to the operator area and falls off. RNA polymerase can then bind to the promoter and transcribe the lac genes. After some time, when the level of lactose decreases as it is metabolized using enzymes, it causes the synthesis of the repressor from the regulator gene. This repressor binds to the operator gene and prevents RNA polymerase from transcribing the operon and the transcription is stopped. This type of law is acknowledged as negative regulation.
Allolactose is a disaccharide comparable to lactose. It consists of the monosaccharides D-galactose and D-glucose linked thru a β1-6 glycosidic linkage alternatively of the β1-4 linkage of lactose. It may additionally occur from the occasional transglycosylation of lactose through β-galactosidase.

How is glucose transported to different cells? And how do you know?
Answer:
Whether a cell uses facilitated diffusion or active transport depends on the specific needs of the cell. For example, the sugar glucose is transported by active transport from the gut into intestinal epithelial cells, but by facilitated diffusion across the membrane of red blood cells.

Actinobacteria sp. are fermenting organisms, which do not require oxygen to survive. These organisms break down organic material and convert it to inorganic material. Which part of the carbon cycle does this describe?
photosynthesis
respiration
decomposition
assimilation
Answer:
decomposition
Explanation:
This describes the decomposition part of the carbon cycle. Therefore, the correct option is C.
What is Carbon cycle?The movement of carbon between the atmosphere, land, oceans and living things is known as the carbon cycle. Many processes exchange carbon, including photosynthesis, respiration, combustion, breakdown, and sedimentation. These activities help maintain the carbon balance that is essential for life on Earth in both the biosphere and the planet's atmosphere.
Another important greenhouse gas is carbon, and the carbon cycle is important in controlling Earth's climate. The natural carbon cycle has been disrupted by human activities, including fossil fuel burning, deforestation, and land-use change, which have also increased atmospheric carbon dioxide concentrations and contributed to climate change.
Therefore, the correct option is C.

a) microbial biofilm plays a major role in the initiation and progression of both dental caries and periodontal infections. b) periodontal diseases and dental caries are nontransmissible diseases.
Microbial biofilm are where the microbe cells stick closely to each other as well as to the surface. They are used in various purposes like: plant protection, bioremediation, wastewater treatment, corrosion inhibition, etc. The biofilm also acts as a hub for the micro-organisms to grow and therefore cause diseases.
Periodontal diseases are the inflammation of the gums. The symptoms on the onset of the disease involve red, swollen and bleeding gums.

When studying cells structure using a microscope the smallest unit of measurement
commonly used to describe findings is the nanometre. Explain why.
Since a nano-metre is the most accurate unit for working with the extremely small cell structure (the majority of cell organelles are between 1 and 1000 nano meters)
Why is it important to measure cell size?The fundamental functions of a cell's physiology, such as flux across membranes, depend on the size of the cell as a whole, which is one reason why cell size matters. Changes in the volume or surface area of a cell will therefore have a significant impact on the metabolic flux, biosynthetic capacity, and nutrient exchange.
Which tool is used to see the smallest units in cells?Under a light microscope, smaller cells are clearly visible. Even internal cell structures like the nucleus, mitochondria, and chloroplasts can be seen. An image is magnified by a system of lenses in light microscopes. Micrometers are used to measure the cell's size. Human red blood cells have a diameter of 7.0 micrometers, while the smallest cell known as Mycoplasma is 0.3 micrometers. Animal and plant cells typically range in size from 10 to 30 microns.

What is turgor pressure and its usefulness to plants in a hypotonic environment?
Answer: Plants thrive in hypotonic environments. Their cells have rigid cell walls that prevents bursting, or lysis. The pressure of the cytoplasm against the cell wall keeps the plant from wilting and losing its shape. This pressure is called turgor pressure or osmotic pressure.
Explanation: On the other hand, cells without cell walls will swell and, if the environment is sufficiently hypotonic, burst (lyse) and die (referred to as cytolysis).
Some protists (such as Paramecium) counteract this with the use of contractile vacuoles that pump water rapidly out of the cell. Other organisms actually eject solutes from the cell in order to lower the concentration gradient of the solute in the cell and hopefully create an isotonic environment. Protists are a very small organism that only live in hypotonic environments.
