. Conduction of heat takes place only in .......
a Solids
b) Liquids
c) Gaseous
d) air

Answers

Answer 1

Answer:

Option A: Solids

Explanation:

Due to the fact that heat is transported from a hotter body to a cooler body when two objects are kept in thermal contact, conduction only occurs in solids and not in liquids or gases. Conduction is the term for this mechanism, which uses the same body temperature. When two bodies remain together during conduction to transfer heat In order to transmit heat energy quickly and more efficiently, the molecules of both entities vibrate and collide with one another. Since solids have compactly packed molecules, this allows the molecules to vibrate more and transfer heat more effectively than liquids and gases. When molecules in close proximity to one another clash, energy is transferred. Due to the molecules' near closeness and, in the case of crystals, their clearly defined structure, this occurs very readily in a solid. A few things alter when heat transport in liquids and gases is taken into account. The molecules are not as close together, and gravity has a particular, confusing influence. Heat is transferred through collisions of nearby particles in a process known as convection. The metal surface particles are transmitting heat to the liquid through conduction at the metal-water interface if convection is occurring between a solid that is hotter than the liquid adjacent to it, such as a pan on the stove. But when that occurs, the water's density begins to alter. The water molecules at the surface move faster, contain more energy, and occupy more space per mass (they are less dense). Because water molecules may pass one another and gravity makes this easier, the less dense water near the metal surface is replaced by the more dense water above it. Natural convection is the mechanism through which a liquid or gas moves in this manner as a result of variations in density. Conduction is no longer possible unless you can prevent the effect of fluid density on the flow of gases or liquids. Fundamentally, in both liquids and gases as well as solids, molecules continue to exchange energy through collisions. Conduction, however, performs this considerably more effectively in liquids at the metal-liquid contact and less so as you travel away from the interface and upward through the liquid. Convection is the movement of particles to transfer heat.

Bottom Line: Conduction may occur in gases and liquids, but you must be able to reduce the impact of gravity. These are known as "stagnant fluids." Convection is the term used to describe fluid movement caused by density variations when they are not prevented.

Answers

The most likely impact on ocean biodiversity is very little because the ocean is large and has high biodiversity.

What is an invasive species?

An invasive species is a species that colonized another environment generally due to human activities.

In this case, it is expected that ocean biodiversity doesn't not suffer changes due to the removal of the invasive species (it is not adapted).

In conclusion, the most likely impact on ocean biodiversity is very little because the ocean is large and has high biodiversity.

Answers

Peptic ulcer disease can be caused by the failure of tight junctions. Thus, the correct option is A.

What is Peptic ulcer disease?

Peptic ulcer disease may be defined as a circumstance in which bitter and painful sores or ulcers evolve in the lining of the stomach or the first part of the small intestine which is the duodenum.

A tight junction is responsible for lining the wall of the intestine or stomach. It helps in the prevention of the passage of digestive enzymes through the space between adjacent locations inside the stomach or small intestine.

If this junction breaches, it results in damage to the wall of the stomach by the acids that help digest food and causes the peptic ulcer disease which is infected by a bacterial organism known as Helicobacter pyroli.

Therefore, it is well described above.

Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!

A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.

This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.
