Answer: The correct answer is D) A cell is the basic unit of structure and function of all organisms.

Cell theory was given by Schleiden and Schwann in 1839. According to this theory-

1) All life forms are comprised of one or more cells.

2) The cell is considered as a fundamental unit of structure and organization in all life forms.

3) Cells are formed from those cells that already existed before.

What property of membranes allows interactions to take place within the membrane, including the assembly of membrane protein clu
Greeley [361]

Answer:

Phospholipid bilayer.

Explanation:

The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is defined as a biological membrane that separates the interiors of a cell from its external environment.

The plasma membrane has a function that protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.

It is composed of a lipids bilayer (phospholipids and cholesterol), (phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group) with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules which hence, regulates the movement of substances in and out of cells. Plasma membranes is very flexible in order to allow cells change form example, red blood cells change shape as they pass through narrow capillaries.

The graph below represents the solar intensity measured over one day in northern Canada. What is the most likely date?
Dmitry [639]
It is important to note that the graph has 0 solar intensity for a long part of the day; around 16 hours. Only from 8 to 16 hours do we have significant sunlight.
This means that the length of day is very short during this time of the year;

The length of the day changes throughout they year; day is equal to night (12 hours each) during the solstices on March 21 and September 23 but during summer day is longer than night in the northern hemisphere; during winter it is smaller. THe smallest daylength is at December 21st (in the northern Hemisphere). This phenomenon is due to the tilt of the axis of the earth.

The correct answer is December 21; (if we talked about a place in the southern hemisphere, the answer would be March 21).

The inheritance of gene expression patterns, in the absence of the initiating signal, is called what
Veronika [31]

The inheritance of gene expression patterns, in the absence of the initiating signal, is called Epigenetic regulation.

Epigenetic changes can be defined as inherited variations which are not present in the DNA sequence. Gene expression is regulated at different levels and not merely in response to DNA modifications. Examples of epigenetic control include DNA methylation, histone deacetylation and mi-RNA expression.

Epigenetic mechanisms add an adaptive layer of control in the regulation of gene expression that allows an organism to adapt to a dynamic environment.

Epigenetic regulation increases the functional intricacy of deoxyribonucleic acid (DNA) by changing chromatin structure, nuclear organization as well as transcript stability.
