The way people use land can affect the levels of nutrients and pollution in soil. Any activity that exposes soil to wind and rain can lead to soil loss. Farming, construction and development, and mining are among the main activities that impact soil resources.Over time, many farming practices lead to the loss of soil.
And as for land ita the same we construct bulidings and dig mines it damages the land. And as land is imporatant for survival of all the of the biosphere we are definntelt responsible for it as well.
Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth. And again it it affects the biodiversity of water preety badly. The marine animals suffer because of our causes.
Biomagnification occurs when the concentration of a pollutant increases from one link in the food chain to another (i.e. polluted fish will contaminate the next consumer and continues up a tropic food web as each level consumes another) and will result in the top predator containing the highest concentration levels. It starts a chain reaction originating from our doings.
pollutants accumlate in bodies of fishes beacuse, they eat unhygienic and non fishFriendly stuffs,it passes on to onother fish.
Humans have come to rely on fossil fuels to power cars and planes, heat homes, and run factories. Doing these things pollutes the air with carbon dioxide. Other greenhouse gases emitted by natural and artificial sources also include methane, nitrous oxide, and fluorinated gases. It leads to destroying of ozone layer in antartica and durther affecting the biodiversity of animals as well as of ourselves.
Biodiversity is the amount of variety of life on Earth. Healthy ecosystems and rich biodiversity: ... Increase ecosystem productivity; each species in an ecosystem has a specific niche—a role to play. Support a larger number of plant species and, therefore, a greater variety of crops. Even if a single animal is cut from the biodiversity( ie. Extinct) the whole of the food chain will collapse
Threats to Biodiversity. The greatest threat leading to the loss of biodiversity is the human race. As our population grows together with our need for food, water, industry, transportation, and home comforts, it takes over natural ecosystems and replaces them with unnatural.
Identify locations of critical wildlife habitat for species at risk and the threats to these areas. Where possible, eliminate threats and maintain natural areas. Leave critical wildlife habitat undisturbed, especially nesting and denning sites. Promote wildlife use by setting up bird and bat houses. And reduce the no of cars and automobiles there are. Avoid usimg of plastic and toxic substances as it causes further harm to biodiversity.
In the its our fault thw animals are close to extinction or alredy extinct. The least we can so is help to conserve and preserve our beautiful and diverse biodiversity.

How are signals “transmitted” into the cell?
Answers
Answer:
Generally, it is the brain that sends signals to parts of the body. It'[s the main headquarters for transmissions and orders.

A model of a biological process is shown. What is the purpose of this process?
a) to assemble nucleotides in an mRNA chain along a DNA template
b) to replicate the DNA of an organism before cell division
c) to synthesize amino acids used to unzip strands of DNA and copy the genetic code
d) to translate the genetic code into a specific sequence of amino acids
Answers
Answer:
The correct answer is - option D. to translate the genetic code into a specific sequence of amino acids
Explanation:
The given model in the figure is the process of translation during protein synthesis. The translation is the process that translates or converts the code carried from the nucleus by the process of transcription which is creating a complementary sequence of mRNA from DNA.
Translation completes in three basic stages initiation, elongation and termination. It is completed with ribosomes; a machine that builds peptide chain by binding mRNA bind to it, tRNA brings the correct amino acids to the ribosome to make peptide chain according to the mRNA code.
The purpose of the biological process shown in this model is: D. to translate the genetic code into a specific sequence of amino acids.
Gene expression in living organism is mainly controlled on two (2) main levels and these are:
Transcription.Translation.Translation can be defined as a biological process through which a genetic code from a sequence of messenger RNA (mRNA) molecule is decoded (translated) to a specific sequence of amino acids during the synthesis of protein.
Form the model, we can deduce that genetic code from a sequence of messenger RNA (mRNA) molecule are being translated into a specific sequence of amino acids.

Make a list of ecological consequences that you can infer have occurred on Guam due to the introduction of the invasive (nonnative) brown tree snake
Answers
Answer:
There are many ecological consequences that could have, or already have, occurred.
Invasive species are notorious for the chaos and destruction they bring upon ecosystems. As an ecosystem is perfectly balanced, a new factor causes this to become askew. The brown tree snake may hunt prey that is the main diet of a different species there. This may cause both the prey and native species to begin to die off, and if the prey goes extinct because of this, the native species will as well, unless they somehow adapt. Not only this, the brown tree snake is known for causing frequent power outages by climbing on electrical wires. They are the cause of the loss of 9 out of 11 forest birds native to Coco's island. They are causing a serious decline in birds, rodents, lizards, and even bats in Guam.
How do you know that energy and matter are conserved during the process of cellular respiration?
Answers
Answer:
Energy and matter are conserved in cellular respiration because it has identifiable inputs and outputs. These can be modeled with chemical equations.
Food undergoes chemical reactions in organisms to generate new molecules for growth or energy. Therefore, energy and atoms are conserved during cellular respiration.
What is conservation of energy and matter in cellular respiration?The law of conservation of energy states that energy cannot be created or destroyed but can be changed from one form to another. The law of conservation of matter states that the total mass within a closed system that does not allow matter or energy to escape should remain constant. However, the law of conservation of energy states that energy can change from one form to another.
The process of cellular respiration is an example of a chemical reaction, which involves the transformation of one type of matter into another. A chemical equation describes this change in molecular structure. This is the cellular respiration chemical equation:
[tex]C_{6} H_{12} O_{6} + 6 O_{2} = > 6CO_{2} + 6H{2}0 + energy[/tex]
(Glucose + Oxygen yields Carbon Dioxide + Water + Energy)
Therefore, the amount of carbon dioxide atoms released by respiration is the same as the amount of atoms in the oxygen and carbon that were changed.
