Answer and explanation:
No, because most people are infected with salmonella by eating foods that have been contaminated by the s-word. Since our society is much more industrialized, we are cleaner when it comes to making food. Salmonella is mostly found in dirtier countries such as third world countries. Obviously, other food-borne illnesses are out there, but salmonella is not as common anymore, since we are improving.
How did Franklin's X-ray photograph affect the work of watson

What happens when green plant leaves absorb energy from the Sun?
A. Plants get too warm.
B. Sugars are produced
C. More green color is produced.
D. Green leaves turn red.
Answer:B. Sugar are produced
Explanation: when green leaves absorb sunlight it is converted to Energy by photosynthesis.
Answer:
I'm pretty sure it's C.
Explanation:
Plants don't get to warm unless they don't have oxygen, sugars are produced, but only during all of photosynthesis, and green leaves don't turn red unless the season is changing. But sun light gives chlorophyll what it needs to produce that green color. Therefor, C is your answer.

What would happen if cytokinesis did not occur?
Answer:
Cytokinesis takes place in both meiosis and mitosis and performs the separation of he cell in half and form one nucleus into each daughter cell.
If cytokinesis did not happen, it will from multinucleated cells which means that their will be multiple nuclei in single cell and cell will not get separate in half, and no new daughter cells will form.

what occurs if a cell is damaged beyond repair?
Answer:
Apoptosis
Explanation:
Answer:
Apoptosis is programmed cell death, and it usually occurs when the DNA of the cell is damaged beyond repair. Photosynthesis and glycolysis are normal metabolic processes of the cell, and would not result from irreversible damage.

What is the structure that breaks the spindle fiber into 2?
Help !!
Answer:
The centromeres
Explanation:
The KINETOCHORE is the cellular structure that breaks the spindle fiber into TWO.
The kinetochore is a structure that associates the duplicated chromatids in eukaryotic cells to spindle microtubules during cell division (either mitosis or meiosis).
The kinetochore forms at the centromere of the chromosomes.
The kinetochore is a disk-shaped structure made up of more than 100 different proteins, especially constitutive centromere-associated network (CCAN) proteins.
In conclusion, the KINETOCHORE is the cellular structure that breaks the spindle fiber into TWO.

What process is the driving force behind evolution?
Answer:
Mutations and natural selection are the main ones
Explanation:
The process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.
What is the significance of natural selection over time?Natural selection is important for the survival of organisms as it is a process by which populations of organisms change over time in response to the outer environment. It is also an important evolutionary mechanism because natural selection always chooses the fittest and natural selection also drives the development of new species and helps ensure the survival of existing species.
Hence, the process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.

Q: Which image shows the most likely path of a barrel floating down a meandering river?
Answer:
C
Explanation:
A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.'
Image C is the most likely path of a barrel floating down a meandering river.
What is the meandering of a river?A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.' The outer edge of the water moves faster than the inner as it flows around these curves.Meanders form as a result of both deposition and erosion, and they gradually migrate downstream. Because of the decreased friction, the force of the water erodes and undercuts the river bank on the outside of the bend, where the water flow has the most energy.To learn more about : Meanders

Answer: What are the options?
Explanation:
Why do traits that give an organism a disadvantage exist during meiosis? Please be as descriptive as possible and write it in your own words
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.

Answer:
Net force is 100 N
Explanation:
You will use the formula to find the net force/force.
mass = 0.05 kg
acceleration = 2000 m/s^2
F = m × a
F = 0.05 kg × 2000 m/s^2
F = 100 N (Newtons)

I’m working on a cell project that is focusing on the nucleus and I have to find a theme song for it. Any suggestions about songs that might relate to the function of a nucleus?
Answer:
https://youtu.be/tRo73dzVfuo
A good song that could serve as a theme song for your cell project is;
The Nucleus Song, sung by Megan and SarahThe song above can serve as a good background for your cell project. It can be gotten from the mainstream video blog under the name Craigdet.
This song is a good choice because its lyrics mention the various parts of the cell, like the ribosomes, endoplasmic reticulum, cytoplasm, etc., and their functions.
It also mentions and displays the nucleus and its role in the cell. The song is educative and entertaining. It will be a good fit for your project.

What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period of years as a result?
Answer:
Eventually, the environment will be unable to support the production of wildebeests, this will cause there to be a loss of vegitation that then causes a food shortage, and then the wildebeests will starve.
Explanation:
It's a very unhappy process, but those herds who don't migrate to another pasture will starve and die. The death will depopulate the savanna and give the fields some time for regrowth and the cycle will begin again.
