Which of the following statements about human society and limiting factors is true?
a. Modifications made to the environment to reduce the impact of limiting factors can cause
disruption to the natural balance of an ecosystem.
b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.

How does energy and matter move through the environment under aerobic and anaerobic conditions?
What happens to energy that is released from food, but not captured and store into
ATP?
Answer:
In conditions of low or no oxygen the process of anaerobic respiration occurs. The 'an' in 'anaerobic' means without. During anaerobic respiration, the oxidation of glucose is incomplete - not all of the energy can be released from the glucose molecule as it is only partially broken down.

In this project, you will use reference materials and Internet sites to do research on a specific type of
genetic modification: genetically modified foods. Suggested references are listed at the end of this
document to help you with this project.
Using your research, you should be able to answer these questions:
1. What are genetically modified foods?
2. What crops are typically genetically modified?
3. Why are crops genetically modified?
4. How are crops genetically modified?
5. How do genetically modified foods affect society and the environment?
You will then share what you have learned by preparing a multimedia presentation. Your multimedia
presentation should include a title slide, a number of content slides that include specific information about
genetically modified foods, and a slide that lists the sources you used in your research.
Answer:
Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.
For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells
GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

The diagram below illustrates a natural Earth process through which the atmosphere
traps heat. Many scientists hypothesize that human activities are accelerating this
process, resulting in a global warming trend. What human activity is believed to have an
adverse effect on the natural process pictured here?
Answer: c. burning of fossil fuels.
Explanation:
Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.
One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

Luís is a rock collector. He thinks that the material from his favorite sedimentary rock in his collection might have been part of an igneous rock formation under Earth’s outer layer millions of years ago. Could Luís be correct?
a.
Yes, energy from Earth’s interior can cause igneous rock to break into small rock pieces that form sedimentary rock.
b.Yes, if igneous rock is moved to Earth’s surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock.
c.No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock.
d.No, sedimentary rock forms at Earth’s surface because energy from the sun causes rock to weather, but igneous rock under Earth’s outer layer is not exposed to energy from the sun.

P2: How do genes determine an individual's traits? (click here to learn how to correctly check the box) Correctly choose one: Genes directly lead to traits. I Genes are random and don't lead to traits. Genes give organisms the ability to change their traits Genes are instructions for making protein molecules and protein molecules determine traits.
Answer:
genes are the basic sequence of DNA that controls the traits of an organisms.
Explanation:
genes have nucleotide sequences. these sequences are involved in transmission of characters from one generation to other. if their is an error occur in this sequence the new offspring will b dissimilar from parent in this secific character which chnaged.
central dogma is the basic process through which genes are controlling the traits. first step is transcriotion through which DNA or gene is transcribed into mRNA sequence. then the second step is translation in which mRNA is translated into protein. in this way by making proteins genes control the traits or functiong of a body.

What else do you think plants may need to grow and go through their normal processes?
Plants need water, oxygen, soil, and solar energy.
Those are the only things that I believe plants need. They need water for food and Solar Energy (basically Vitamin D which you get from the sun) and soil to grow. Obviously they need oxygen to be able to survive.

Two species of fish are introduced to the same lake. Over time, only one species survives. According to Darwin's theory of evolution, what should characterize the surviving species
Answer: Both species must have competed for the same niche. The surviving species is better adapted or adapted better and outcompeted the other.
Explanation:
According to Darwin's theory of evolution (survival of the fittest), the surviving species would be fitter than the extinct fish.
What is the theory of survival of the fittest?Charles Darwin proposed the idea of the "survival of the fittest," which states that organisms that are most adapted to their environment have a higher chance of surviving and reproducing. Charles Darwin proposed natural selection as a crucial aspect of evolution.
Natural selection refers to the process by which an organism becomes more likely to thrive and produce more offspring the better it is able to get food and avoid becoming prey. The process of evolution is driven by this "survival of the fittest," which results in species surviving as a whole.
Thus, according to Darwin's theory of evolution, the surviving species would be fitter than the extinct fish.

What is the significance of a balanced diet for maintaining a healthy level of biomolecules in our cells and body to function disease-free?
Answer:
A balanced diet makes our body work in the best possible way. Both the lack of food and the excess of them is detrimental to health, therefore the appropriate amounts must be consumed for each individual. It meets our basic physiological needs and reduces the risk of disease.
Explanation:
Food is the set of processes that allows organisms to use and transform nutrients to stay alive. A balanced diet will largely depend on the human being leading a healthy life. The foods that are consumed each day must have adequate amounts of both the macronutrients (carbohydrates, proteins, lipids), as well as the micronutrients (minerals and vitamins) and water, which are bioavailable that the consumed diet must contain, in order to satisfy the requirements physiological of each individual. In addition to covering individual variability, for some nutrients an additional amount is added to establish a margin of safety. Complying with the appropriate amounts avoids and prevents overweight, obesity, as well as chronic degenerative diseases such as diabetes mellitus, dyslipidemias, cardiovascular diseases, cerebrovascular disease, etc. and in turn helps the person to look and feel better, increasing physical and mental performance. Poor nutrition means neglecting some nutrients or overdoing others. This is the main factor that promotes progressive weight gain and obesity according to experts.

hich statement is a correct description of the processes of respiration and transpiration in a plant?
Question 6 options:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Transpiration is when the plant pulls water into its roots. Respiration is when the plant breathes.
Transpiration is when the plant grows over time. Respiration is when the plant breaks down the sugar in its roots.
Transpiration is when the plant produces buds. Respiration is when the plant dies.
Answer:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Explanation:
Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.
Contrarily, RESPIRATION is a cellular process in which the cells of a plant breakdown sugar molecules (glucose) in order to release energy (ATP) in the process. Respiration equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Explanation:
Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.
