Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this? A.The oils in the lotion enter the skin cells by means of phagocytosis.
B.The oils in the lotion enter the skin cells with the help of carrier proteins.
C.The oils in the lotion enter the skin cells by means of facilitated diffusion.
D.The oils in the lotion enter the skin cells by means of simple diffusion.

Answers

Answer 1

Answer:

The right answer is D.

The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.

This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.

External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.

William is interested in exercising more, but does not feel he has the time. Write a short response explaining how he can find the time to exercise

Answers

Exercising doesn't mean you have to spend hours in the gym. Exercises can be done at the comforts of your home too, and there's plenty of exercise available, especially for those who have less time to do so. Just like for example, waiting time. While you are waiting for your clothes in the washing machine to finish, you may use this time to do some basic exercises such as running in place, jumping jacks or carrying weights. It may only take a few minutes, but performing these exercises in less time is better than not doing it at all.

Answer:

Finding time to exercise can be difficult, but it is important to consider time spent exercising as important time, as important as social commitments, work, and school. Therefore, effective strategies to increase time for exercise include scheduling blocks of exercise time, making people more aware of your exercise time, analyzing your schedule for the best time to exercise, pursuing activities that can be done from home, finding places to exercise that are close to home, work, or school, and finding a person with whom you can exercise.

Explanation:

If secretory proteins are isolated from secretory vesicles and injected into the cytosol, they will A. remain in the cytosol until they are degraded. B. be secreted through channels in the plasma membrane. C. be taken up into the rough ER and follow the secretory pathway. D. be taken up into secretory vesicles and secreted.

Answers

Answer: Option C

Explanation:

The secretory proteins are found inside the cell which is secreted by the Endoplasmic reticulum and moves from the same route towards the Golgi apparatus.

Although it is secreted from the endoplasmic reticulum of the cell, but if it is injected from the outside to the inside of the cell then it moves to the rough endoplasmic reticulum and follows the secretory pathway of the cell.

Hence, the correct answer is option C

Which graphic organizer would help you visualize the similarities and differences between whales and dolphins? herringbone organizer Venn diagram context chart

Answers

Answer:

Option C, Venn Diagram

Explanation:

Venn diagram is a mathematical logical relationship that represents the relationship ship between two or more set of data through intersecting circles. The intersection area between the circles represent the similarities between the different set of data while the non-intersecting area of the circle represent the individualistic characteristics of each data set.

Hence, the characteristics of whale and dolphin can be represented by two circles in which the intersecting area of the circle will contain the similarities between the whale and dolphins and the non-intersecting areas will contain their individual unique characteristics.

Venn diagram. Hope this helps!
