New Zealand has a population of 4,326,380 and has an area of 103,736 miles squared while Australia has an area of 2,967,909 miles squared and a population of 21,905,140. Explain how New Zealand can have a larger population density than Australia even though it has a smaller total population.
The reason they have a higher population density is because they have more people on average in a certain area, because New Zealand is smaller they are given less space to live, this means that more people are crammed together, making the density of people within a square mile higher. When you give less square miles, you reduce the amount you have to divide the population by, which makes the density go up.
( In case you wanted the calculations for the density on New Zealand and Australia, it is about 41 to 42 people a square mile in Zealand, and maybe 7 or 8 per square mile in Australia.)

The time it takes for an animal to metabolize a drug to a non-detectable levels could be ____ than that of the withdrawal period 
A:Longer
B:Shorter
C:Same time
The time it takes for an animal to metabolize a drug to a non-detectable levels could belongerthan that of the withdrawal period. Hence the correct option is A.
The metabolism of a drug refers to the process by which the body breaks down and eliminates the drug from the system. The withdrawal period is the time required after administering a drug during which the animal must not be slaughtered for human consumption to ensure that no residues of the drug are present in the edible tissues.
There are several factors that can influence the metabolism of a drug in animals, such as the drug's chemical properties, the animal's species, age, health status, and metabolic rate. Some drugs may be metabolized relatively quickly, while others may take longer to be completely eliminated from the system.
Hence the correct option is A.

Answer:
1. In the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
a. The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
b. In the Calvin cycle (light independent reactions), carbon atoms from CO2 are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).
2. When transitioning to respiration, photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
3. Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
a. Fermentation refers to the metabolic process by which organic molecules (normally glucose) are converted into acids, gases, or alcohol in the absence of oxygen or any electron transport chain.
4. They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
Explanation:
1. A process in which the plants prepares their food from inorganic compounds and light energy is called photosynthesis.
The energy stored in the carbohydrates is used in the preparation of chemical energy.
a. In reactions that use light for the process is called light-dependent reactions. It transpires in the thylakoid organelle of the chloroplast. The light is needed for the synthesis of ATP and NADPH which is a reduced electron carrier.
b. The reactions in which the carbon dioxide is fixed from the carbon source to produce three-carbon sugars is called light-independent reactions. The process of the Calvin cycle transpires in the stroma of the chloroplast.
2. When transpiration changes to the respiratory pathway then glucose is produced during photosynthesis and is used in the process of cellular respiration to produce ATP.
The produced glucose gets converted back into carbon dioxide through the process of expiration.
The water molecules get broken into oxygen during photosynthesis and in another process of cellular respiration, the oxygen combines with hydrogen to yield water.
3. The aerobic process that requires oxygen molecules to break glucose molecules in living organisms to produce ATP and releases energy is called cellular respiration.
The process comprises a reaction between glucose and oxygen to produce carbon dioxide and water.
a. The metabolic process in which the organic molecules are converted to gases, alcohol and acids in the absence of ETC or oxygen is called fermentation.
4. The process of photosynthesis and cellular respiration have similar molecules as:
In the photosynthesis process molecules produced are oxygen, carbohydrates that are high in energy and get converted to glucose or other sugar molecules. In cellular respiration, glucose gets broken into water and carbon dioxide.

(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.
Answer:
The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.
Explanation:
Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.
The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:
Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.
The other options are not correct because:
a. Breaking down damaging toxins created by bacteria is an anti-toxin function.
b. Antibiotics do not increase the number of white blood cells in the blood.
d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.

What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?
O The water would move out of the cell and the cell would decrease in size.
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?
2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.
Answer:
No.
Explanation:
No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.
Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

- Cancer cells invade healthy tissue.
- Cancer cells display contact inhibition.
- Cancer comes in many forms.
- Cancer cells divide uncontrollably.
and I think "Cancer does not obey contact inhibition." is one too... I hope this helps! :D
Explanation:
Cancer cells:
• Divide uncontrollably
• Comes in many forms
• Invade healthy tissues
• Does not obey contact inhibition
What is cancer?Cancer is a diseased condition in which uncontrolled cell division takes place.
Cancer are of two main types: benign and malignant.
Benign tumours are localized to a particular organ and thus can be removed through chemotherapy or surgery.
Malignant tumours spread to body parts through blood stream and attack the healthy cells. This property of metastasis is unique to cancer cells.
Normal cells show their contact with the adjacent cells. In cancer, contact inhibition is lost and so they divide in an uncontrolled manner.
Breast cancer, leukaemia, lung cancer etc are some of the examples of cancer.
Cancer is detected through tissue biopsy. X-Rays, CT-Scan, MRI are some other techniques that detect cancer in the body.
Cancer can be treated if diagnosed early. Radiotherapy, chemotherapy and surgical intervention are the part of cancer treatment.
Therefore, cancer is considered a serious medical complication.
