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.

Enter the sequence of the DNA coding strand with a 5-3 polarity. DO NOT WRITE 5 OR 3 OR 5' OR 3' IN THE BOX!
Complete question:
Use the sequence below to answer the following questions
3’-ACGGATCCTCCCTAGTGCGTAATACG-5’
5’-TGCCTAGGAGGGATCACGCATTATGC-3’
1. Enter the sequence of the coding strand with a 5’-3’ polarity
Answer:
coding strand → 5´- GCATAATGCGTGATCCCTAGGCA -3´
Explanation:
When referring to the coding strand, we are talking about the sequence that turns to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.
The coding strand receives that name because it is the sequence that codes for each amino acid composing the proteins.
When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.
The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.
Whenever we have a DNI molecule and we need to determine which strand is the coding one, we just need to look for the presence/absence of start or stop codons.
So, in the exposed example we have two strands, but we do not know yet which one is the coding one.
Conventionally, the first strand is always the coding one. However, let us analyze it by using the presence/absence of codons.
First-strand:
3’-ACGGATCCTCCCTAGTGCGTAATACG-5’
let us write it is 5´to 3´direction
5´- GCATAATGCGTGATCCCTAGGCA -3´
now let us identify the start and stop codons in 5´⇒3´direction.
Start codon ⇒ ATGStop codon ⇒ TAA, TAG, TGA5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 1 start codon at the beginning
5´- GCATAATGCGTGATCCCTAGGCA -3´ ⇒ 3 Stop codons
Second strand: We will do exactly the same procedure
5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 start codon near the end
5’-TGCCTAGGAGGGATCACGCATTATGC-3’⇒ 1 stop codon at the beginning
What we did here was to identify in both provided strands, where the start and stop codons are placed. We can see that in the first strand we have the start codon near the beginning, while in the second strand we have it near the end of the sequence. From this information, we can assume that the first strand is the coding one. However, you need to know that some coding sequences do not have start and stop sequences, because they might correspond to a sequence in the middle of a gene.
So, the sequence of the DNA coding strand with a 5-3 polarity is
5´- GCATAATGCGTGATCCCTAGGCA -3´
The extinction vortex represents the idea that even if an organism is extant, it may have a gene pool that will not support its long-term survival.A. TrueB. False
Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.

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

Should we clone animals that are going or have gone extinct (in other words bring them back
either from the brink of extinction or from extinction)? Explain your answer.
Answer:
I think we should but people are preventing this though
Explanation:
I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

Explanation:
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

Answer:
The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.
Explanation:
Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.

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.
----------------------------------------------------------------------------------------------------------
The proximity of the pond to agriculture might be considered as an independent variable.
The researcher chooses ponds according to their distance from the crops. In the exposed example, the researcher chose a pond is surrounded by high-density livestock areas and another one at least ten miles away.
The magnitude of run-off might depend on how far the pond is from the crops.
