Answer:
D. Bar graph
Explanation:
A bar graph is one of the types of graph or charts used to display statistical data. They are used to compare data between different groups. A bar graph makes use of either vertical or horizontal bars, which displays the actual data being compared.
Like other graphs, a bar graph contains a X-axis (horizontal), which contains the pizza toppings being compared and a Y-axis (vertical), which contains the number of people who chose each pizza. At the end, it will be easy to determine which pizza toppings is most popular from the bar graph because the pizza with the longest bar suggests the most popular.

Answer:
It’s D it can prevent food borne diseases
Explanation:
right on EDGE 2021
Food Irradiation solves a societal problem by preventing food-borne diseases. Thus, the correct option for this question is D.
What is Food Irradiation?Food Irradiation may be defined as a type of technology that significantly enhances the safety and security that enlarge the shelf life of foods by minimizing or eliminating microorganisms and insects from food products.
The process of food irradiation remarkably makes food and its derivative products safer and healthier for consumers. It also delays the ripening of fruits, enhance rehydration, inhibits sprouting, enhances liquid or juice yields, etc.
It utilizes the technology of ionizing radiation electricity that emits X-rays and gamma rays for the destruction of microorganisms such as viruses, bacteria, or any other types of insects in the food as well.
Therefore, food irradiation can solve a societal problem by preventing the cause of food-borne diseases. Thus, the correct option for this question is D.

2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
Atom is a basic unit of matter have proton and neutron containing nucleus at the center and surrounding electrons.
What do you mean by atom ?
Atoms are the smallest and basic units of matter.
A negatively charged electron which surround the nucleus of the atom moving around the orbitals or energy levels.
The nucleus does not change during chemical reactions, only in nuclear reactions it will change.
In nucleus equal number of protons and neutrons, atomic number is the number of protons and atomic mass is made of the sum of protons and neutrons.
Relative mass of a matter is the mass of a proton while Relative charge of a matter is the charge on a proton.

O A. The origin of eukaryotes
O B. How species develop
O C. How bacteria live
O D. Why cells rely on one another
Answer:
A) the origin of eukaryotes
Explanation:
The Endosymbiotic theory talks about how the ancestors of modern eukaryotic cells were once 2+ prokaryotic cells. This theory says that one prokaryotic cell basically lived inside another prokaryotic cell and these cells formed a long term relationship. The prokaryotic cell eventually became a permanent part of the host and eventually evolved into modern day eukaryotic cells.
The Endosymbiotic Theory explains the origin of eukaryotes.
What is endosymbiotic theory?The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes.
The most significant examples of endosymbiosis are represented by the endosymbiotic acquisition of plastids and mitochondria, introducing photosynthesis and respiration to eukaryotes.
Eukaryotic cells may have evolved when multiple cells joined together into one. They began to live in what we call symbiotic relationships. The theory that explains how this could have happened is called endosymbiotic theory.

SCIENCEEEEEEEEE Frieda makes a pyramid of oranges for a display at the grocery store. A few minutes later, Corwin bumps into the display and the oranges spill down. Which change of state does the motion of the oranges most closely model?
The correct answer is A. Melting
Explanation:
Melting occurs in solids as these change their state to liquid state, usually due to high temperatures. For example, if one cube of ice is exposed to heat it melts. This physical change implies the solid loss its defined shape and particles in it are not as organized as before.
This process is exemplified by the situation of the oranges because the pyramid of oranges had a defined shape and the oranges were arranged in a defined pattern; however, in the end, this shape changes, and the particles (oranges) are no longer organized in a strict pattern. Also, the distance between particles increases, which also happens when solids become liquids.

Scientific Process , Describe its importance
Answer:
The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can't escape bias. It results from personal beliefs, as well as cultural beliefs, which means any human filters information based on his or her own experience. Unfortunately, this filtering process can cause a scientist to prefer one outcome over another. For someone trying to solve a problem around the house, succumbing to these kinds of biases is not such a big deal. But in the scientific community, where results have to be reviewed and duplicated, bias must be avoided at all costs.
That's the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions. Even with such a rigorous methodology in place, some scientists still make mistakes. For example, they can mistake a hypothesis for an explanation of a phenomenon without performing experiments. Or they can fail to accurately account for errors, such as measurement errors. Or they can ignore data that does not support the hypothesis.

Flatworms
James H. Thorp, D. Christopher Rogers, in Field Guide to Freshwater Invertebrates of North America, 2011
B Reproduction and Life History
Some flatworms, especially those living in temporary aquatic habitats, reproduce only once per year (univoltine), while other species are multivoltine, with the number of generations depending on environmental favorability. Most flatworms reproduce sexually, and almost all species are hermaphroditic. Although gamete exchange is most common, self-fertilization is possible in some species. Eggs are laid singly on a hard substrate, are grouped into clusters (sometimes stalked), or are placed in cocoons. Miniature flatworms emerge from eggs which have been attached to the substrate. These usually develop directly (without intermediate larval stages) into adults and differ only in size and presence of reproductive organs. A few species are ovoviviparous (young brooded inside parent) or have a distinct larval stage. Asexual reproduction occurs seasonally in many taxa and is the only form of reproduction in a few species. This form of reproduction involves differentiation of the adult body into distinct units (zooids) followed by separation into small flatworms via transverse division of the adult body. This process is aided by the remarkable regenerative abilities of flatworms.
Under demanding environmental conditions, flatworms produce resistant eggs able to survive desiccation of the surrounding environment or the animal may enter diapause (a very low metabolic state) and encyst as a whole animal or fragment of the adult.
Sexually reproducing flatworms can live from a few weeks to a few months (not counting periods of encystment), while the life span of asexual species is theoretically indefinite.
