if a solute concentration gradient has been established across a membrane, the permeable solute will diffuse across the membrane:

Answers

Answer 1

Permeable solute will diffuse across a membrane if a solute concentration gradient has been established: from the side with a higher concentration to the side with a lower concentration.

The bigger the concentration difference between two locations, the steeper the concentration gradient and the faster the rate of diffusion.

Temperature: As the temperature rises, so does the energy and hence the movement of the molecules, which increases the rate of diffusion.

The concentration gradient, membrane permeability, temperature, and pressure all influence the rate of diffusion.

The concentration gradient influences the movement of osmosis; the lower the concentration of a solute inside a solvent, the faster osmosis will occur in that solvent.

Answer:

Ingestion is when food comes into the body through the mouth and down the esophagus. Digestion begins with chemically with enzymes in saliva, and mechanically with the teeth, and continues when food (as a bolus) enters the stomach to be dissolved by acid and pepsin. Food (chyme) then goes into the small intestine where nutrients are absorbed through the villi. Waste is then eliminated through the large intestine, rectum, and anus.

Answers

The parts of the amniotic reptile egg include the amniotic fluid, the albumen, and the shell.

Parts of an amniotic reptile's egg

The various parts of amniotic reptile's eggs include:

The external shell which serves as a protective layerThe yolk which supplies energy to the embryoThe albumen supplies the embryo with water and proteinsThe extra-embryonic membranes - the chorion, the allantois, and the amnion.

The chorion serves as a channel for gaseous exchange between the embryo and the environment.

The allantois partially functions as waste manager and in respiration. It stores nitrogenous wastes and gets rid of them as well as participates in gaseous exchange along with the chorion.

The amnion protects the embryo against mechanical shocks. It also protects the developing embryo from being dehydrated.

In other words, the 3 extra-embryonic membranes protect, facilitate gaseous exchange, and ensure that wastes are properly disposed of.

What is Framing effect?

The framing effect is a cognitive bias in which the brain makes all the decisions about information depending upon how the information is presented to them. In this, people decide the options which were based on whether the options are presented with positive or negative connotations to them. For examples: the students doing examination.

People tend to avoid the risk when a positive frame is presented to them however they seek the risks when a negative frame is presented to them. Framing effect occurs when the decisions which people make are changed as a result of the way in which the outcomes are described to them.

Therefore, the correct option is C.

Economic profit equals zero when total revenue (TR) equals total cost (TC).

The statement is true. Economic profit equals zero when total revenue (TR) equals total cost (TC).

In Economics, total cost is defined as the sum of costs that is incurred by firm for the production of certain level of output.

Mathematically, it is calculated as:

TC (total cost) = TFC (total fixed cost) + TVC (total variable cost)

Fixed cost refers to a cost that does not change with an increase or decrease in the number of goods or services produced or sold.

Variable cost changes with an increase or decrease in the number of goods or services produced or sold.

Total revenue is also called gross revenue. It is the total amount of income your company brings in from selling your products/services.

2. Bone
A 68-year-old Asian female presents with mildly achy muscles and joints. The aches seem to “come and go” quite often lasting for several days at a time. Upon examination you take note of a hunch-backed appearance on the patient. An x-ray is performed and showed a significant decrease in bone tissue mass. After further diagnostic testing is performed the patient is diagnosed with Osteoporosis. TAKE NOTE: Osteoblast cells build bone matrix while osteocytes maintain the matrix. Osteoclast cells break down bone matrix and reabsorb the nutrients.
Using your knowledge of the human physiology, which of the following do you predict is a potential cause of the Osteoporosis?
A. Decreased osteoblast activity B. All choices are potential causes
C. Increased osteoclast activity D. Secondary to external factors like drugs/cancers

Answers

Osteoporosis causes bone density to decrease due to decreased osteoblast activity, increased osteoclast activity, and external factors like long-term medication. Option B. All choices are potential causes.

What are the factors that promote osteoporosis?

Let us first review what the bone cells are and their functions,

Osteoprogenitores → in charge of osteocytes production

Osteocytes → maintain the matrix

Osteoblasts → Synthesize and secrete osteoid matrix that will later calcify

Osteoclasts → Phagocytic cells in charge of osseous resorption and bone modulation.

Osteoporosis is a no-symptoms disease -silent- that causes a decrease in the bone mineral and mass density and might change the bone structure.

Osteoporosis weakens the bone until it breaks. So this affection becomes evident when a fracture occurs.

Several factors lead to osteoporosis development. Among them, we can mention,

genetic factors, habits factors (lifestyle),hormonal alterations,drugs/medication

The increased rate of bone resorption is the major mechanism by which osteoporosis occurs. It deteriorates bone structure and decreases bone density.

Bone resorption and deterioration might be caused by

a decrease in osteoblast activity, leading to the decrease in osteoid matrix formation and calcification,

an increase in osteoclast activity, enhancing the activity of these phagocytic cells.

Other external factors also increase the probability of developing osteoporosis. Some of them are,

long-term medications (for instance, those used in cancer treatment) excessive alcohol consumption and smokingsedentary lifestylepoor diet

According to this framework, the potential causes of the Osteoporosis are Decreased osteoblast activity, Increased osteoclast activity, Secondary to external factors like drugs/cancers.

Hence, option B is correct, All choices are potential causes.
