how is the oxygen cycle disturbed by deforestation
Answer:
If deforestation is disturbed then the photosynthesis cycle is disturbed, which results in the oxygen cycle being affected. With a decrease in trees, a decrease in photosynthesis occurs, which cause a decline in the oxygen cycle. A decline in the oxygen cycle results in more polluted air.
Explanation:
Without trees, humans would not be able survive because the air would be unsuitable for breathing. Due to deforestation, there would be fewer trees to "clean" the air. Deforestation is the action or process of clearing of forests, or the state of having been cleared of forests.
Trees and plants, in general, produce energy for growth using a process known as photosynthesis. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air.
Deforestation, as well as a rise in the emissions and our global temperature, affects the air that we breathe. This is because all trees take in carbon dioxide and other pollutants which are known to cause a lot of problems in the atmosphere and to humans. This inevitably results in people breathing dirtier and more polluted air that normally wouldn't happen.
Long-term exposure to polluted air can have permanent health effects such as: Accelerated aging of the lungs. Loss of lung capacity and decreased lung function. Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.
Trees are responsible for taking the carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly higher amounts of carbon dioxide in the air and lower amounts of oxygen. This bad quality air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide.
In addition to the decrease of oxygen in the atmosphere, it would allow excessive amounts of carbon dioxide to remain. In the short term, since CO2 is one of the major greenhouse gases, it will undoubtedly lead to higher global temperatures which, in turn, would quicken the melting of the polar ice caps.

prevention of the spread of bovine tuberculosis (
Answer:
no. badger vaccination is better
Explanation:
spreading mostly happens cattle to cattle
"killing badgers will not solve the problem. Badgers are not the primary cause of the spread of bTB in cattle: the primary route of infection is cattle-to-cattle contact[2]. The Government's badger cull is flying in the face of science. It should be putting more resources into speeding up the development of an effective cattle vaccine, amongst other measures"

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, will an action potential be produced?
Answer:
Yes
Explanation:
If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, the action potential will be produced. In a chemical synapse, an action potential in the presynaptic neuron is responsible for the release of a chemical messenger known as neurotransmitter. After this, the neurotransmitter diffuses across the synapse and binds to the postsynaptic cell so we can say that potential can be produced.
The importance of water properties on plants and animals
The importance of water properties on plants and animals.
Answer:The importance of water in plants is that it helps plants to make their own food, because water plays a very important role in Photosynthesis, and as well it helps them to grow.
The important of water in animals is that it is main need for animals to survive as well as humans. Without water even a single organism won't exist in this Earth.
Hope it helps you :)The human body is made up of more than three-fourths of water, and all animals and plants require water to thrive.
Why water is essential for plants and animals?Water is used by all living things to transport nutrients throughout the body and remove waste. Among its many crucial functions, water aids in the digestion of food and the preservation of organisms' heat.
The term "universal solvent" refers to water's enormous capacity to dissolve a wide range of molecules, and it is this capacity that makes water such a priceless life-sustaining agent.
Water's function as a solvent aids cells in the transfer and utilization of molecules like oxygen or nutrients on a biological level.
Therefore, to do all the cellular processes by plants and animals there is need of water.

7. Shawn plotted the data in a bar graph with two bars: one representing the number of bees per colony in the control cages and the other representing the number of bees per colony in the cages exposed to the fungicide. If the results support the hypothesis that fungicides harm bee development, what would you expect this bar graph to show? Describe the expected pattern in a few sentences.
Answer:
The first bar increases in length as compared to the second bar.
Explanation:
The length of the bar of control cages in graph increases because the number of bees per colony increases while on the other hand, the length of the bar of the cage that is exposed to fungicides decreases because the bees are negatively affected from the application of fungicides. They act abnormal in behaviour and adversely affected the reproduction of bees that greatly affected its population.

The predominant forms of actin inside a cell are ATP-G-actin and ADP-F actin. What would be the consequence for actin filament assembly/disassembly if a mutation prevented actin's ability to bind ATP
Answer:
If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.
Explanation:
As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.
What is the phase that not all cells enter, but it is a phase where cells are not actively dividing
Answer:
The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.
Answer:
G₀ phase
Explanation:
Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.
Elephants are considered K-strategists because they give birth to only one calf at a time and most have five years in between having another calf. Calves stay under the protection of the mother and her herd until maturity at 10-15 years of age. What type of survivorship curve do elephants tend to follow
Answer:
Type I curve
Explanation:
The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).

Size exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel.
What is size exclusion chromatography?
Size exclusion chromatography (SEC) splits molecules based on their size by filtration via a gel. The gel consists of spherical beads including pores of specific size distribution. Separation happens when molecules of various sizes exist included or excluded from the pores within the matrix.
Size exclusion chromatography exists named gel filtration chromatography because the gel effectively allows for the filtering of molecules from a sample based on molecular size. However, unlike other methods, the larger molecules elute first.
Size-exclusion chromatography (SEC), also understood as molecular sieve chromatography, exists a chromatographic procedure in which molecules in solution exist separated by their size, and in some cases molecular weight. It exists usually applied to large molecules or macro molecular complexes such as proteins and industrial polymers.
