"Geckos use a force and not suction to adhere to surfaces. Describe how this force works"

Biology
1 answer:
Finger [1]3 years ago
7 0

Answer:

Geckos use a force not suction to adhere to the surface. This force is van der wall force. The toepad of geckos has many thousand setae that are keratinized and each setae have fine hairs called spatulae.

The van der walls force between the spatulae and the surface helps in the adhesion geckos to the surface. Van der waals is the sum of repulsion and attraction formed during electrostatic interaction.  In this force two atoms come to that much close that they create a subtle nuclear attraction.

Apart from Vanderwall force, capillary force also helps in adhesion. Vander wall force play a primary role in adherence on hydrophobic surface.

Hiiii mind helping me?
Elza [17]

Answer:

Please see the explanation.

Explanation:

Req. a)

Greater susceptibility to infections.

In Leukopenia, the amount of white blood cells becomes lower in the bloodstream. A normal white blood cell usually has 3.5k to 11k white blood cells per micro-liter.

But a leukopenia patient might have a lower number of white blood cells than 3.5k to 11k. White blood cells are which fight against unwanted viruses, bacteria, etc. which enters into the human body. Actually, it works as a guard for humans from being affected by various diseases.S So, it's crucial for the human immune system.

When the amount of white blood cells becomes lower, the body will become less prepared to battle against viruses and infections. So if a person becomes affected by leukopenia, he/she will be more susceptible to the disease.

Req. b)

Transport fluid.

The lymphatic system is an arrangement of different tissues and organs. The lymphatic system helps the body to get rid of poisons, garbage, and as well as from other unwanted elements. Inside the body, lymph is carried out by the lymphatic system. Lymph is a liquid that contains infection-fighting white blood cells.  The lymphatic system helps to pass this fluid (lymph) throughout the body so that this lymph can help all cells to get rid of unwanted materials.
