Describe how natural selection is related to evolution
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.

food
oxygen
wastes
water
Answer: water, and oxygen
Explanation: Homeostasis depends on maintaining correct fluid levels within the cell and on exchanging useable materials, such as oxygen, for waste products, such as carbon dioxide. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.

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.

Discuss how algae help support other life on earth?
Answer:
In the distant past, algae helped turn the earth's then inhospitable atmosphere into one that could support modern life through photosynthesis, which plants use to turn carbon dioxide and sunlight into sugars and oxygen. Some of the algae sank to sea or lake beds and slowly became oil.
what effects pollution has on people 's life?
Explanation:
Short-term exposure to air pollution can irritate the eyes, nose, and throat and cause upper respiratory infections, headaches, nausea, and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease.
if the skeletal muscle cells in your leg are performing lactic acid fermentation to produce the necessary ATP for their proper functioning, decribe what is happening to the O2 gas you are breathing
Answer:
The O2 gas in uses in Aerobic Respiration and That O2 is performing that process to make ATP for your body and making glucose to function your body
Explanation:
Lactic Acid Fermentation is Anaerobic Respiration which doesn't Involve Oxygen
Sorry if I'm wrong
Hope this helps!
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.

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.

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.
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.

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.

2) why might nucleotides be know as the building blocks of DNA ?
3) what elements can be found in the structure of DNA if DNA is composed of nucleotides?
Answer:
it becomes clear that the bulk of DNA can be isolated from the nuclear fraction, The Three Roles of DNA are G, C, and T. Figure 2-1 shows the structures of the four nucleotides in DNA. There are two with pyrim-idine bases) that are the fundamental building blocks of DNA.

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.
