How does the burning of fossil fuels contribute to climate change?
When fossil fuels exist burned, they release large quantities of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, pushing global warming.
What is fossil fuels?Fossil fuels exist created from decomposing plants and animals. These fuels exist found in the Earth's crust and include carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas exist examples of fossil fuels.
A fossil fuel exists as a hydrocarbon-containing material constructed naturally in the earth's crust from the remains of dead plants and animals that exist extracted and burned as a fuel. The primary fossil fuels exist as coal, crude oil, and natural gas.
When fossil fuels exist burned, they release large quantities of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, pushing global warming.
Global warming exists usually directed to human-induced warming of the Earth system, whereas climate change can be direct to natural or anthropogenic change. The two phrases are often used interchangeably.

release water vapor
absorb water and nutrients
store water and glucose
perform photosynthesis
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Conifer Leaf.
Microphyll Leaf.
Megaphyll Leaf.
A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.
The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

Explanation:
During the process of DNA replication, the whole molecule gets copied in the synthesis or S phase of the cell cycle. The DNA strands are separated by the enzyme helicase while topoisomerase keeps it from overwinding. The 2 strands are copied differently. The leading strand is made continuously, while the lagging strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is DNA polymerase. This enzyme can only add nucleotides to an existing strand, so short sequences of nucleotides (primer) made by the enzyme primase are needed for the process of elongation. In the lagging strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while DNA ligase joins the fragments.

Antennae development in ants is thought to be a trait controlled by maternal effect. In ants, zig-zag coils are dominant to curly coils. Assume that a female develops zig-zag coils. What can be determined about inheritance of this trait in her family?
a. Her mother has zig-zag antennae.
b. Her brother has zig-zag antennae.
c. This female carries the zig-zag allele
d. This female's offspring will have zig-zag antennae.
Answer:
a. Her mother has zig-zag antennae.
b. Her brother has zig-zag antennae.
Explanation:
Available data:
Antennae development ⇒ controlled by maternal effectZig-zag coils are dominantCurly coils are recessiveA female develops zig-zag coilsMaternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. Even though the progeny has a different genotype, it is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. The maternal effect is commonly seen in insects and might be seen in some mammals and plants.
So, if a female has zig-zag coils, this means that the mother also has zig-zag antennae and that all the brothers and sisters of this female ant have zig-zag antennae, independently of their genotype.
a. Her mother has zig-zag antennae ⇒ True. The trait is inherited from the mother.
b. Her brother has zig-zag antennae ⇒ True. The whole progeny will express sig-zag antennae.
c. This female carries the zig-zag allele ⇒ Not necessarily.
d. This female's offspring will have zig-zag antennae ⇒ Depends on it´s genotype
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.

Answer:
you can see below
Explanation:
Basic Definitions:
Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.
Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.
Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.
Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Why do all proteins given a negative charge prior to electrophoresis?
Answer:
The principle for native gels when Coomassie is not added to the sample is that proteins are separated by a combination of size and charge. The charge in general depends on the number of amino acid residues that bear a positive or negative charge at the pH of the gel. So if running the gel at pH from 8.3 / 8.9, Asp and Glu will be negatively charged, Lys and Arg and His will be protonated and have a positive charge. The N- terminus would have a positive charge while the C terminus would have a negative charge. There might be exceptions depending upon the micro environment of each residue. Native gels can be run at acidic pH as well, to give another way of resolving proteins. Smaller proteins migrate faster than larger proteins. Also, quaternary structure is preserved, so a dimer will run as a dimer so the percentage of total acrylamide monomer used is usually lower than what is used for SDS-PAGE, e.g. 7.5% acrylamide

the control group the independent variable the dependent variable the hypothesisAnswer:
2. the independent variable
Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The election of a control group is essential in an experiment. Its principal purpose is to allow the discrimination of the results obtained by the treatment in the study, from the results that might be a consequence of other factors. The control group does not receive any treatments. It is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one that receives the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.
Dependent variable: Refers to the variable that depends and reacts to any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. This change might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y.
The hypothesis is a conjecture. The researcher hypothesizes in order to predict what is going on or what is expected to occur. A hypothesis is a claim of how it works a relation between two or more variables. Usually, it is written in the present time.

imagine that you are conducting tests shortly after a nuclear accident.Using potted moss plants as you experimental organisms,design a experiment to test the hypothesis that the frequency of mutations decreases with the organisms distance from the source of radiation
Answer:
Take two potted plants and provide equal conditions to both.
Explanation:
Two potted plants i.e. one is placed near the nuclear accident site while on the other hand, the other is placed far away from the nuclear accident. Provide equal conditions to both plants so that we can find out the hypothesis that the frequency of mutations decreases with the organisms distance from the source of radiation. The result shows that the potted plant that is located near to the nuclear accident site having high frequency of mutation as compared to other plant due to the radiation present at that location.
