Regular physical exercise is a great way to improve your overall well being. Exercise controls weight, improves mood, boosts your energy and metabolism, improves sex life and promotes good sleep. The physical activity is usually accompanied by increase in body temperature and sweating. What is the reason for the increase in the body temperature? Explain the relationship between sweating and body temperature and the significance of this feedback. What type of feedback system? identify all components of the feedback system.
Answer:
Explanation:
"A part of your brain called the hypothalamus controls your body temperature. In response to an infection, illness, or some other cause, the hypothalamus may reset the body to a higher temperature. So when a fever comes on, it's a sign that something is going on in your body."
Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialized ribonucleases that degrade mRNA soon after its synthesis. C) are sequence-specific DNA endonucleases. D) are very specific proteases that cleave peptides at only certain sequences. E) catalyze the addition of a certain amino acid to a specific tRNA. c The biological role of restriction enzymes is to: A) aid recombinant DNA research. B) degrade foreign DNA that enters a bacterium. C) make bacteria resistant to antibiotics. D) restrict the damage to DNA by ultraviolet light. E) restrict the size of DNA in certain bacteria.
Answer:
C) are sequence-specific DNA endonucleases
Explanation:
Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are EcoRI, BamHI and HindIII, isolated from Escherichia coli, Bacillus amyloliquefaciens and Haemophilus influenza, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.

II. Write a position statement on whether you think athletes like Santhi should be allowed to compete. Use evidence based reasoning in your position.
Answer:
The correct answer is stated in the Explanation section.
Explanation:
Santhi Soundarajan is an Indian track and field athlete that have won multiple international medals. Santhi was the center of a controversy when she was striped her silver medal after failing a sex verification test at the 2006 Asian Games. Santhi has a condition known as androgen insensitivity syndrome, she carries a Y chromosome althoug she has female genitalia. I think is not fair to disqualify an athlete like Santhi unless it is determined that she committed fraud and that she has an evident advantage. If Santhi knew her condition and it is established that she has an advantage after multiple tests, then her medal could be removed.

CELLS: Choose three membrane-bound organelles. Describe them below.
Include their shape, location, and a detailed description of their function.
Answer:Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Explanation:
Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. Eukaryotes also have a golgi apparatus that packages and distributes proteins. Mitochondria are the power house of the cell and provide the cell with energy.

CELLS: Describe the structure of a eukaryotic plant cell. Indicate the ways in
which a non-photosynthetic prokaryotic cell would differ in structure from this
generalized eukaryotic plant cell.
Answer:
A cell that is nonphotosynthetic, such as a prokaryotic bacterium, would not require chloroplasts to function.Explanation:
A broad sweeping eukaryotic plant cell accomplishes the basic functions required for plant care. It's a jumble of organelles held together structurally by the cell membrane, which is located outside of the cell wall.
What is eukaryotic cell?Plant and animal cells are eukaryotic, which means they contain nuclei. Plants, animals, fungi, and protists all have eukaryotic cells.
They typically have a nucleus organelle surrounded by a membrane called the nuclear envelope, which stores DNA.
Prokaryotes are typically simpler, requiring only a few organelles to survive. This is frequently because, as previously stated, it requires less energy.
It has DNA to contain genetic material, ribosomes to make proteins, a cell membrane, and a cell wall to protect the cell from its surroundings. While other components are produced by prokaryotes, the ones listed above are those that may be found in plant cells.
Aside from that, the non-photosynthetic prokaryotic cell requires much less energy, resulting in a cell that is much smaller and less complex than the generalized eukaryotic cell.
Thus, this way, a non-photosynthetic prokaryotic cell would differ in structure from this generalized eukaryotic plant cell.

4. What material passes through a hole of a strainer when sieving
is used to separate mixtures?
Answer:
Explanation:
A strainer is a device that is used to remove foreign/specific "dirt" from a liquid (usually when flowing). Strainers usually have holes just like a sieve except that this time, it separates dirt (tiny solids) from the liquid unlike a sieve that separates solid particles of different sizes.
It should however be noted that sometimes the strainer is designed to remove a valuable "dirt" from the flowing liquid.
Very small particles such as fine flour particles can pass through the hole of the strainer.
Those particles which are smaller in size of the hole of the strainer can pass through it while on the other hand, large particles can pass through it. Sieving allows the fine flour particles to pass through the holes of the sieve but prevent or stops the bigger particles from entering the sieve so we can conclude that very small particles can pass through the hole of the strainer but the large particles can't.

I need a short personal paragraph on clean neighborhood for work.
All of us live in a neighbourhood or surrounding. We must keep our surroundings neat and clean. This will help us to live a healthy life. Keeping our surroundings clean will only help in the betterment of society. Waste or garbage should not be thrown anywhere, but only in trash bins. Throwing garbage all over the place will dirty our surroundings, pollute the environment. Controlling the use of plastic bags will help to keep our surroundings clean. One should use recycled and eco-friendly products like paper or jute bags instead of others. Littering causes land, air and water pollution. Greener surroundings look beautiful and reduce pollution. Dirtying our surroundings will cause harm to us. So, keep the surroundings clean, live happy and healthy lives.
HOPE IT HELPS YOU .Fish are sensitive to many environmental variables: dissolved oxygen, light, temperature, pH, clarity of water, food supply, presence of predators, etc. Fish will be attracted to different locations in a lake, based on its mix of variables.
Imagine you want to conduct an experiment to understand how just one of these variables differs in a local lake, depending on its depth. This lake reaches a depth of 17 meters. For this activity:
Pick a variable that might change as you go deeper in the lake on a given day.
Do a little research on that variable to determine how you might measure it in a lake.
Use the template below to outline an experiment to investigate this variable in the lake by depth. For each part, simply answer the question in parentheses to create your outline.
Type your response to each field in the space below that field:
Title: (Enter a brief, descriptive title. Hint: Sometimes it’s best to do this last.)
Purpose: (Why are you doing this experiment?)
Hypothesis: (What do you predict from this experiment and why?)
Procedure/Method: (How will you specifically carry out your experiment to test your prediction?)
Observations: (What specifically would you look for and record?)
Data analysis: (With this kind of data, what would be the best way to present it?)
Conclusion: [No need to enter anything here for now.]
References: (List any references you used to design the experiment. Note that for a full experiment write-up you’d also list any references you used while carrying out the experiment or in analyzing your results.)
Answer and Explanation:
Variable: dissolved oxygen
Title: Oxygen variation as a water quality indicator.
Purpose: To study how dissolved oxygen varies with depth
Hypothesis: The percentage of dissolved oxygen will decrease as depth increases.
Procedure/Method:
Selection of sampling spots, according to the morphometry of the lake, different depth, water currents inputs and outputs, aquatic vegetation, and lake type of use. In each spot water samples will be taken using a Niskin bottle. The sample will be taken from different depth: 5 meters deep, 10 meters deep, and 15 meters deep (photic zone).Dissolved oxygen (DO) will be measured in each sample, by using a multiparameter sensor. In a field sheet to evaluate the parameter, the %DO by site and depth will be recorded.Observations:
%DO in each site and depth will be recorded in order to analyze how it varies with depth.
Data analysis:
According to different indicators of water quality in a lake, the observed %DO will be compared and analyzed to evaluate the sanity state of the lake water. Example of valuation scale,
NORMAL index: Oxygen concentration in the water column is found to be sufficient for the fish survivalREGULAR: Decrease in oxygen concentration at greater depth, values below saturation in the backgroundCRITICAL: Null oxygen concentration in all or part of the column profile of water. Probable fish mortality events.According to the taken data, observations on the study site will be taken, such as the variation in oxygen concentration as it gets deeper, until reaching hypoxia level, where fishes can not survive. Data can be presented in tables and in graphs, in both cases comparing sampling sites and depth, making a focus on the valuation scale.
Conclusion:
Association of the oxygen variation with the sanity state of the lake, microbiology decomposition processes at different depths, eutrophication state, among others.

This monarch butterfly has orange wings. Is orange
the genotype or the phenotype? Explain
Answer:
Phenotype
Explanation:
It's phenotype because a genotype is not a physical trait; a genotype means genes. It's phenotype because it a physical trait you can see. Lets say twins look the same on the outside but on the inside they have completely DNA. This is like how some butterflies look the same with orange wings but one might have a mutation in its genes.
