Answer:
Microorganisms that are not visible are so called because their measurements are in micrometers and even nanometers.
We usually talk about viruses, bacteria, fungi and even parasites.
Explanation:
Microorganisms are mostly pathogens for humans, but others make up the commensal biota of the same living being.
Not all microorganisms need the same means to live and develop as large organisms such as those that are simple to the human eye.
Some microorganisms are seen by optical microooscopy and others smaller by electronically.

Humans process some foods by adding chemicals to reduce bacterial growth, contain the production of toxins, and improve taste. This allows foods to be edible for longer periods of time. Which best describes the advantages of food processing? Control of density-independent limiting factors control of density-dependent limiting factors decrease in food nutrient levels adverse health affects
Answer:
The correct answer is - control density-dependent limiting factor.
Explanation:
Density-dependent factors are the factors that show various effects on the population size and growth based on the density of the population and effects vary with different density of population.
These factors are generally biotic such as competition for food and space and many other factors. Food processing involves the processes that help food to be edible for a longer period.
Availability of food depends on the density of the population which makes it is a density-dependent factor, processing is advantageous as if it maintains the food for a longer time or gives control over the density-dependent factor.

What would the Earth be like if it had no atmosphere?
Answer:
It would be silent. Sound requires a medium to transmit waves. You could feel vibrations from the ground, but you wouldn't hear anything.
Birds and planes would fall from the sky.
The sky would turn black. It's blue because of the atmosphere.
It would be a vacuum so All plant and animal life on the Earth's surface would die.
Even if survive you'd get a massive sunburn on exposed skin because the Earth's atmosphere is what filters solar radiation.
The rivers, lakes, and oceans would boil. Boiling occurs whenever vapor pressure of a liquid exceeds external pressure, in vacuum there is no pressure. Even if water still be there it would freeze.
Answer:
It would be like Mars. There wouldn't be any oxygen for living things

3.
release of chemicals which cause helpful mutations
4.
loss of genetic material available for research
Answer:
Explanation:
4.
When rainforests are cut down, there is a significant loss of genetic material available for research purposes. The correct option is 4.
What is a rainforest?
Rainforests are dense and diverse ecosystems characterized by high levels of rainfall and rich biodiversity. They are found in tropical regions near the equator, where temperatures and humidity are consistently high throughout the year.
Rainforests host a wide variety of plant and animal species, many of which have unique genetic characteristics and adaptations. These genetic resources hold immense value for scientific research, including the development of new medicines, agricultural improvements, and understanding of evolutionary processes.Destroying rainforests cause loss of access to potential sources of new drugs, the genetic diversity that could enhance crop breeding programs, and opportunities to study and understand the intricate interconnections and adaptations of species.Therefore, the correct option is 4.

Answer:
For a cookie to be converted into a source of energy it is necessary for the chewing system, the endocrine system and the digestive system to function.
Explanation:
The masticatory system would begin with the formation of the bolus, together with the enzymatic action of alpha amylase, in addition to simplifying the macromolecules into micromolecules for better digestion and absorption.
The digestive system would take care of the destruction of polysaccharides into monosaccharides for assimilation and incorporation thanks to a necessary enzymatic combo and a ph set.
On the other hand, the endocrine system is the star system for the assimilation of glucose, which is the monosaccharide product of the digestion of the cookie, insulin is the hormone that is responsible for providing the entry of glucose to the cellular LIC, that is, inside the cell for it to unfold and form the energy currency known as ATP.
How would you fix the following run-on sentence:
Going to school was a nice escape I felt like I was always arguing with my brother at home.
Going to school was a nice escape. I felt like I was always arguing with my brother, at home.
Answer:
Going to school was a nice escape, I felt like I was always arguing with my brother at home.
Explanation:
A comma (or a period) would fix the run-on sentence because "going to school was a nice escape" is a independent clause, as "i felt like I was always arguing with my brother at home" is as well. But being that they are connected a comma would be best

1. A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were
added before each test flight. As each paper clip was added, the plane was tested to determine how far it would
fly.
Independent variable ___________________________
Dependent variable ____________________________
Control _____________________________
Constant ____________________________
2. Two groups of students were tested to compare their speed working math problems. Each group was given
the same problems. One group used calculators and the other group computed without calculators.
Independent variable ___________________________
Dependent variable ____________________________
Control _____________________________
Constant ______________________________
3. Students of different ages were given the same puzzle to assemble. The puzzle assembly time was measured.
Independent variable ___________________________
Dependent variable ____________________________
Constant ______________________________
There can be several controlled variables. If an experiment is to be useful, only one variable at a time can
be manipulated intentionally. All other variables must be controlled throughout all parts of the
experiment. If more than one variable is altered (changed), the results of an experiment cannot be
interpreted with any validity.
4. An experiment was performed to determine how the amount of coffee grounds could affect the taste of
coffee. The same kind of coffee, the same percolator, the same amount and type of water, the same perking
time, and the same electrical sources were used.
Independent variable ___________________________
Dependent variable ____________________________
Constants (3) ____________________________________________________________
Answer:
1. Independent variable- paper clips
Dependent variable- how far it will fly.
Control- mass of plane
Constant- type of plane
2. independent variable- using calculators
dependent variable- who will answer the questions faster
Control- the time the groups get done with the math problems
Constant- the math problems
3. Independent variable- Age of children
Dependent variable- the time it takes to complete the puzzle.
Constant- The type of puzzle
4. Independent variable- Amount of coffee grounds
Dependent variable- The taste of the coffee
Constants(3)- The same kind of coffee, same type of water, and the same perking time.
Explanation: The dependent variable depends on the independent variables change. For example: The amount of coffee grounds determine the taste of the coffee. The coffee grounds would be the independent variable because the dependent variable is the taste of the coffee, and the taste of the coffee determines on how much coffee grounds we use. Constants are the things that stay the same during the experiment. For example: We use the same brand of coffee throughout the experiment, so the brand of coffee is our constant. The controls are the things that do change. For example: The paper clips on the plane weighed the plane down more and more each experiment. So, the control would be the amount of paper clips used each test. The mass could also be a control in this experiment because the change in the paper clips changes the mass of the plane. I did this in 7th grade, and i am in 11th, so I know this is correct. I hope this helps you:)

Answer:
At the very end of the air passages, are clusters of tiny air filled sacs called alveoli . These air sacs are surrounded by small blood vessels called capillaries
Explanation:
The name of the tiny blood vessels that surround the alveoli is Capillaries.
What are capillaries?Capillaries are the places where the exchange of substances between the blood and adjacent tissues takes place. Substance exchange can occur both between the cells that form the vessel wall and across it. Pores present in some types of blood capillaries also act as transfer sites.
Blood capillaries or capillaries as the lining of these little balls are called, are blood vessels of the circulatory system in the form of small tubes. In them, there is a large amount of carbon dioxide that diffuses into the alveolar air.

Because plants can't search out sources of water, Madison wonders what special adaptations they must have for storing water. In plants, this is reflected in the larger size of what organelle?
Answer:
It is reflected in the larger size of VACUOLE
Explanation:
Plants have larger VACUOLE compare to animals because VACUOLE is an organelle present in plants that help plants store water and other materials.
Even plants stop growing, the VACUOLE serve as storage units that stores large volume of water and food. These special adaptations in plants enable them store water in VACUOLE organelle which is use for metabolic processes in the plant cells.
Discuss alcoholic fermentation including the function of the production of ethanol, as well as an example of an organism that carries out this process.
Answer:
Yeasts by fermenting carbohydrates as a product obtain alcohols, of which they are ethanol.
Some yeasts are edible and are used in the dough to lift them, others are not considered edible.
On the other hand, there are two types of fermentations, acidic and alcoholic, yeasts that are fungi ferment carbohydrates to give ethanol as a product.
Explanation:
Alcoholic fermentation occurs because the molecular structure of the carbohydrate adds an alcohol group, and this is what characterizes the alcohol within this group. Ethanol is an alcohol that has two carbons and an alcohol group accompanied by hydrogens that complement the four bonds of each carbon.
The term et of ethanol refers to the presence of two carbons in organic chemistry.
