Cell membranes allow some molecules to move freely across the membrane, while
other molecules are restricted. which term best describes this capability of a cell
membrane?
a. semipermeable
b.
impervious
c.
resilient
d. unyielding

A. semipermeable

Explanation:

The plasma membrane is semipermeable because it has the property of selective permeability, which controls the entry and exit of substances in the cell.

In other words, it is as if the plasma membrane acts as a filter, allowing smaller substances to enter, as well as making it difficult for larger substances to pass through.

Substances such as excretion and carbon dioxide come out as water, oxygen and food enter. The selective permeability process is essential for maintaining metabolic processes in cells.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
