Optimism bias is the perception towards risk that Mary has.
The optimistic bias is a term to refer to the human tendency to see the future positively and better compared to the past and the present. The optimistic bias includes the tendency to underestimate the possibility of negative things happening, such as illness, car accidents, and unemployment.
According to the above, Maria has a perception of optimistic bias because she is underestimating the possibility of getting sick even though all of her friends have gotten sick. This may be reinforced by the fact that she is in good health and that is why she does not think it is necessary to get vaccinated.
Additionally, the degree of control, instant gratification, and catastrophe options are not correct options because they are types of perception different from optimistic bias.

, where should the capillaries and lymphatic vessels be placed tomaximize the absorption of nutrients from food
Answer:
They should be placed in the small and large intestine.
Explanation:
The small and large intestine is the part of our digestive system that absorbs the nutrients from food. Previous to this step, the food went through the mouth, the esophagus, and the stomach. In those places, it was processed so that the intestines could absorb the nutrients from the food easily/
For nutrients to be absorbed, they should be in stretch contact with the intestines' walls where the smallest arteries, which are called capillaries, are present and will take the nutrients into its interior where the blood is. Also, the intestines have lymphatic vessels. These ones will protect our body from any antigen since they are part of our immune system.
In chemical reactions atoms are
Neutralized
Destroyed
Created
Rearranged
Answer: Rearranged
Explanation:
In chemical reactions, atoms cannot be destroyed, created, or neutralized, and that is why the only correct answer, in this case, is that atoms in chemical reactions can be rearranged.
They aren't destroyed and they can never be destroyed and also they cannot be created because of the law of conservation of energy in chemical reactions.
This law is considering that ''A matter cannot be created nor destroyed, it can only be formed in one way or the other.''
Which statement below best describes the function of the nucleus?
Answers:
a) Stores cells wastes and destructive enzymes
b) contains hereditary information and controls most of heredity and cell processes
c) directs cell division in animal cells
d) controls water pressure and stores wastes
Answer:
b) contains hereditary information and controls most of heredity and cell processes
it contains and protects DNA
Explanation:
The statement that best describes the function of the nucleus is that it contains hereditary information and controls most of the heredity and cell processes.
Cells are recognized as the building blocks that make up organisms. These cells are further made up of several structures that are well defined. Those well-defined forms of structures are referred to as organelles. The Endoplasmic reticulum, Mitochondria, and Nucleus are some of the examples of cells’ organelles.
The function and features of the nucleus are listed as follows:
The nucleus is described as the structure that is bounded by the membrane It is also considered the most noticeable organelle based on its function and size This organelle consists of the hereditary information of the particular cell and further helps in controlling the reproduction and growth of the cell.Thus, we can conclude that the statement “contains hereditary information and controls most of the heredity and cell processes” best explains the function of the nucleus.

Eurasian Plate
Answer:
The answer is A - Convergent boundary resulting in earthquakes and volcanic activity
Explanation:
In map, Convergent boundary resulting in earthquakes and volcanic activity.
What do you mean by convergent boundary?A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. A convergent boundary is an area on Earth where two or more lithospheric plates collide.
Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up.

Explanation:
Why I know this because I just took the test
Based on the information in the graph Australia's population is currently growing the least.
How much has Australia's population grown in the last 50 years?Australia's population almost doubled in the past 50 years, from 13.1 million in 1971 to 25.7 million in 2021. But more remarkable is that this record population growth has exceeded all forecasts.
Why Australia is underpopulated?Australia has an average population density of 3.4 persons per square kilometre of total land area, which makes it one of the most sparsely populated countries in the world. This is generally attributed to the semi-arid and desert geography of much of the interior of the country.

Explain the differences between DNA and RNA.
Answer:
Explanation:
The difference between DNA and RNA is.....
DNA = Double-stranded
RNA = Singer-stranded
DNA = The sugar moiety is deoxy ribose
RNA = Ribose is the main sugar
DNA = Thymine is always there, but uracil is never found
RNA = Pyrimidine components differ. Thymine is never found
DNA = It follows Chargaffs rule (since it's double stranded)
RNA = Doesn't follow Chargaffs rule (since it's single stranded)

Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel.
Coal:
Petroleum:
Natural gas:
In each case, what is the end product of burning the fossil fuel, and where does it go?
Answer:
Coal:
Coal is primarily used as fuel to generate electric power
Petroleum:
heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials
Natural gas:
heating, cooking, and electricity generation.
it all end up in the atmosphere
Explanation:
The coal is burned and the heat given off is used to convert water into steam, which drives a turbine.
petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria.
Like oil, natural gas is a product of decomposed organic matter, typically from ancient marine microorganisms, deposited over the past 550 million years. This organic material mixed with mud, silt, and sand on the sea floor, gradually becoming buried over time.
Coal and natural gas are burned in power plants to boil water. Steam from boiling water converts turbines into electricity. Carbon dioxide from burning fuel is released into the atmosphere.
This is about description of fossil fuels which are simply fuels that are formed from natural processes.
The uses and end products of fossil fuels are talked about in the explanations below;
1) (I) The primary use of the fossil fuel named coal is to generate electricity.ii) When coal is burnt, it produces a very high heat. This heat is so high that it converts water into high-pressure steam. What drives a turbine is a high pressure steam and this drive makes the turbine to produce electricity.
2) I) Petroleum products are used to set vehicles in motion, for asphalt on roads, production of electricity and heating of buildings.II) when petroleum is burnt to create energy, it produces high amount of carbon dioxide and other toxic gases into the atmosphere that can cause greenhouse effect.
3) I) Natural gas is used primarily as a source of energy for cooking, generating heat and for providing electricity.II) When it undergoes combustion is produces large amount of carbon dioxide and nitrogen oxides into the atmosphere.
