Answer:

This question appears incomplete but The correct option is the last option

Explanation:

Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.

____ [38]

Frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

<h3>Is frozen water more or less dense than liquid water?</h3>

Ice is less dense than liquid water because when the water becomes solid due to low temperature, the density of ice become decreases. Due to less density, the ice floats on the water surface.

Water is attracted due to its polar nature so adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces. These forces pull water and the dissolved minerals from the roots to the upper parts of the plant.

So we can conclude that frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

Which system runs perpendicular to the myofibril and functions with the triad as a microtransportation network to spread the act
Svetlanka [38]

Answer:

The preferable options will be -

T-tubule system

Explanation:

  • T-tubules or transverse tubules are a part of the skeletal and cardiac muscle membrane systems. They are the cell membrane extensions that can penetrate into the center of those muscles.
  • It contains a large amount of on channels, transporters, and pumps. It allows the transmission of the action potential, frequently. T-tubules also regulates the cellular calcium concentration.

Students construct a graphic organizer to illustrate the different levels of biological organization.
erastovalidia [21]

Answer:

B--Organism

Explanation:

Different levels of biological organization start from the least complex object and end at the most complex. Every object has objects preceding it that it is made up of.

In this question, the organ system is made up of several organs. A community is made up of several populations of different people. Think about this now: what makes up a population and is made up of organ systems? The most logical answer here according to the flow is B--an organism. An organism is made up of organ systems and makes up a population, which in turn allows several populations to make up a community.
