Explanation:
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.

What type of energy change cause the leaf to grow?
A. Electromagnetic energy is transferred into chemical energy
B. Thermal energy is transformed into potential energy
C. Electromagnetic energy is transferred to the leaf
D. Thermal energy is transferred to the leaf
Answer:Electromagnetic energy is transferred into chemical energy
Explanation:photosynthesis
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose.

Examples of ovoviviparous animal
Answer:
sharks, rays, snakes, fishes, and insects
Explanation:
These ovoviviparous animals produce eggs, but instead of laying eggs, eggs develop inside the mother's body. The eggs are laid in the mother. After rocking, they stay in the mother for a while and feed there. Then the young are born live.
Ovoviparity is, therefore, a mixture of oviparous (animals that lay eggs) and viviparous (animals that develop in the mother’s body).
The genus Cnemidophorus is a large group of whiptail lizards that are found in both North and South America. These lizards undergo a process in which their unfertilized eggs can develop into new individuals. This process is called
Answer: The question is not complete, options are not given but here are the options from another websites.
a. sexual reproduction.
b. binary fission.
c. parthenogenesis.
d. budding.
The correct option is C.
Parthenogenesis.
Explanation:
lizards undergo a process in which their unfertilized eggs can develop into new individuals and the process is called parthenogenesis because parthenogenesis is a reproductive strategy that involves the reproduction of new organisms without undergoing fertilization or the production of new organisms from unfertilized eggs and these can be as a result of the lizard not able to undergo sexual reproduction which can be as a result of environmental factors. This process does not involve sexual reproduction.

Which of the following best explains why aerobic respiration is more energy efficient than anaerobic respiration?
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.

which set of characteristics below describes a carbohydrate?
Answer:
supplies energy and fiber
Explanation:
Carbohydrates are what provides the body with fast, immediate energy, vs fats which are long term energy.
Carbohydrates are the source of energy thus the molecules that are used here are the energy molecules in the process of food metabolism as well.
What is the best source of carbohydrayte ?It is the whole grains, fruits and vegetables.
Along with the proteins and fats there are carbohydrates that are one of these three main nutrients that are in the foods and drinks. Our body is breaking down into the carbohydrates into the glucose. Glucose or blood sugar is main source of the energy for our body's cells, tissues and organs.
The primary role of the carbohydrates is to supply out the energy to the all of the cells in body. Many cells are preferred as the glucose that are a source of the energy where the other compounds as the fatty acids. Certain cells such as red blood cells are only there to produce out cellular energy out from glucose.

what is the function of the Diaphragm
Answer: It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.

What is an allele?An allele is a given gene form, diploid organisms inherit two alleles for gene locus, one from each parent.
A diploid individual can be for a given gene locus:
Homo-zygousHeterozygousAn individual is homo-zygous when it inherits the same allele or gene variant for a particular gene locus.
Conversely, an individual is heterozygous when it inherits different alleles for a given gene locus.

carbohydrate synthesis
active transport
dehydration
diffusion
Answer:
I think it’s active transport
The laboratory setup would most likely be used to demonstrate the process of diffusion.
What do you mean by Laboratory?A Laboratory may be defined as a place where a variety of experiments may be performed depending on the work or projects it handles.
In this experiment, an artificial cell containing glucose and starch solution is dipped into the water containing a starch indicator.
The concentration of glucose or starch is found to be high in the artificial cell, hence, it removes the water or particles from the inside to the outside of the cell.
Diffusion may be defined as the movement of particles or matter from a region of high concentration to a region of low concentration.
Therefore, the laboratory setup would most likely be used to demonstrate the process of diffusion.
