The role of the cell membrane is most like the job of which person?
Answer:
The officer that allows people in and out of the crime scene.
Explanation:
The cell membrane chooses what comes in and out of the cell, therefore the officer would be most similar to the job of the cell membrane.
Answer:
It has a job similar to a police officer who allows select people to enter and leave a crime scene.
Explanation:
The primary purpose of the cell membrane is to preserve the cell from its surroundings. The cell membrane manages the movement of materials in and out of cells and organelles. In this form, it is selectively perforable to ions and organic molecules. It is the same as of police officer or security guard that check the people and allow only a few to enter a specific place.

A fruit fly is classified as a heterotroph, rather than as
an autotroph, because it is unable to
A) transport needed ntaterials through the body
B) release energy from organic molecules
C) manufacture its own food
D) divide its cells mitotically
Answer:
C
Explanation:
heterotrophic oragnisms gain energy from other oragnisms and need to break down complex organic molocules to release energy.
A fruit fly is classified as a heterotroph, rather than as an autotroph because it is unable to manufacture its own food.
What do you mean by Autotrophs?Autotrophs may be defined as those organisms which are capable of synthesizing their own food in the presence of sunlight.
Fruit fly takes energy from other organisms and are hence known as heterotrophs and release their energy by the breakdown of complex substance.
Therefore, a fruit fly is classified as a heterotroph, rather than as an autotroph because it is unable to manufacture its own food.

Answer:
D. it would produce smaller amounts of more concentrated urine
Explanation:
In salt water, the concentration of salt would be higher outside the cells than inside. Therefore, the concentration of water inside the cells is higher outside than in. Water leaves the skin and gills via osmosis, moving from a high concentration to a low concentration.
This means the urine is highly concentrated, and produced in small volumes (as most of the water has left via osmosis, not urination)

Describe how the skin cells, neurons, muscle cells, and blood cells you have observed relate to the functions of skin, nerve, muscle, and blood tissue.
Answer:
The form makes the function, this saying is named by many scientists, and they were the ones who made a relationship with the physiology of the organ or tissue and the shape of the cells that make it up.
Explanation:
In the case of neurons, they have extensions to spread and transmit signals, epithelial cells form many layers and have the ability to shed, that is why their main function is the body's innate protective barrier.
Red blood cells are double-headed and enucleated, to be made up of proteins that conform to oxygenation and thus diffuse oxygen well throughout the body.
And finally the muscle cells, which are tapered, with internal sarcomeros, similar to an elastic, to be able to carry out effective contractions starting from a certain length.
How does a cis double bond affect a fatty acid tail? How does this compare to a trans double bond?
What happens to the concentration of lactic acid as workout intensity increases? What happens to blood pH as the concentration of lactic acid increases?
As exercise intensity increases there comes a break point where blood lactate levels will start to rise (production starts to exceed clearance). This is often referred to as the lactate threshold i think (LT). If exercise intensity continues to increase a second and often more obvious that increase in lactate accumulation is seen.
If an increase in acid overwhelms the body's acid-base control systems, the blood will become acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing (respiratory compensation). hope this helped
How do high temperatures
affect enzyme activity?
Answer:
Increased temperatures can cause enzymes to work more quickly, if the temperature gets too high the enzyme stops working.
Explanation:
If the temperature around an enzyme gets too high, the enzyme loses its shape, which is known as denaturation, and ceases to work.

Answer:
Osmosis across the membrane
Explanation:
The diagram shows the movement of water molecules from outside the cell to the inside of the cell. The concentration of water molecules is higher outside of the cell than inside the cell, meaning the water molecules are moving from a high concentration to a low concentration across the semi-permeable membrane, a process called osmosis.
Exocytosis is the movement of molecules from the inside of the cell to the outside via a vesicle. The vesicle fuses with the plasma membrane and the contained substances are released outside the cell.
Active transport is the movement of molecules against their concentration gradient and requires energy.
Facilitated diffusion is used by molecules that cannot freely cross the plasma membrane (e.g. large polar molecules and ions)
Answer:
Osmosis across the membrane

Hope this helps. :)
Photosynthesis uses carbon dioxide and releases oxygen and cellular respiration uses oxygen and release carbon dioxide.
What is photosynthesis?Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.
The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.
The equation of photosynthesis is represented below:
[tex]6CO2+ 6H2O - C6H12O6 + 6O2[/tex]
The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.
In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.
Therefore, Photosynthesis uses carbon dioxide and releases oxygen and cellular respiration uses oxygen and release carbon dioxide.

Answer:
Plants perform both photosynthesis and cell respiration and cause a net decrease of carbon in the atmosphere.
Explanation:
Plants are living organisms capable of performing a process called photosynthesis, which they use to synthesize their food (sugar). They use carbon in form of carbon dioxide, which they absorb from the atmosphere via their stomata.
However, plants like every other living organism, also perform cellular respiration. Cellular respiration releases carbon in form of carbon dioxide into the atmosphere. Plants use more carbon dioxide than they release into the atmosphere, hence, they contribute to global carbon cycle perform both photosynthesis and cell respiration and cause a net decrease of carbon in the atmosphere.

Explanation:
Photosynthesis is a series of metabolic reactions by which plants and algae use sunlight, water (H2O), and carbon dioxide (CO2) to produce molecular oxygen (O2) and energy in the form of carbohydrates (glucose).
Photosynthesis has two types of reactions:
The light-dependent reactions. These reactions convert light energy into chemical energy (ATP and NADPH).The light-independent reactions (dark reactions or Calvin Cycle). These reactions fix carbon from CO2 into molecules which are then used to produce sugar (glucose).The reactants in the light-dependent reaction include light and water (H2O).The products of the light-dependent reactions are ATP, oxygen and NADPH.The reactants in the dark reactions are ATP, NADPH and carbon dioxide (CO2).The product of the dark reactions is sugar (carbohydrates).In conclusion, photosynthesis has two types of reactions: light-dependent reactions and light-independent (Calvin Cycle) reactions.
