Unanswered Questions. HS-LS Use a model based on evidence to illustrate the relationships between systems or between components of a system. Plan and conduct an investigation individually and collaboratively to produce data to serve as the basis for evidence, and in the design: decide on types, how much, and accuracy of data needed to produce reliable measurements and consider limitations on the precision of the data e.

HS-LS Constructing Explanations and Designing Solutions Constructing explanations and designing solutions in 9—12 builds on K—8 experiences and progresses to explanations and designs that are supported by multiple and independent student-generated sources of evidence consistent with scientific ideas, principles, and theories.

A: Structure and Function Systems of specialized cells within organisms help them perform the essential functions of life. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.

Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level.

Feedback mechanisms can encourage through positive feedback or discourage negative feedback what is going on inside the living system.

B: Growth and Development of Organisms In multicellular organisms individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow. The organism begins as a single cell fertilized egg that divides successively to produce many cells, with each parent cell passing identical genetic material two variants of each chromosome pair to both daughter cells.

These proteins eventually make their way through the ER to be captured within budding transport vesicles.

The transport vesicles travel to the Golgi apparatus, fuse with it, and release their proteins within this organelle. The mitochondrion is an organelle found in all eukaryotic cells. This organelle transforms the energy from food molecules, such as glucose, into a form of energy the cell can use for work: ATP, or adenosine triphosphate. The production of ATP using fuel molecules and O 2 is called cellular respiration.

Cristae Cristae singular crista are the numerous infoldings of the inner membrane of the mitochondrion. These folds tend to be quite regular and shelflike. They greatly increase the inner membrane's surface area. Inner and outer membranes Mitochondria have two membranes—inner and outer membranes. The outer membrane is smooth and protective and offers little resistance to the movement of substances into and out of the organelle. The inner membrane contains many large protein molecules that participate in cellular respiration and the production of ATP.

Matrix The matrix is the region of the mitochondrion that is enclosed by the inner membrane. In addition to many proteins, the matrix contains some ribosomes and DNA that are used to make some of the proteins needed for cellular respiration. The nucleus is usually the largest organelle in a cell. Chromatin Chromatin is a complex of DNA and proteins.

Chromatin strands are exceedingly long, thin, and entangled during most of the life of a cell. However, just before cell division, the chromatin condenses into thick bodies, called chromosomes, that are readily visible under a light microscope. Nuclear envelope The nuclear envelope consists of two membranes that encircle the nucleus. Each membrane consists of a lipid bilayer. Nuclear pores perforate the envelope and connect the interior of the nucleus with the cytoplasm.

At these pores, the outer membrane of the envelope is continuous with the inner membrane. Nuclear lamina The nuclear lamina is a network of filaments just inside the nuclear envelope. The nuclear lamina interacts with chromatin and helps support the envelope to which it is attached.

Nuclear pores The nuclear pores perforate the nuclear envelope and allow certain molecules to pass between the nucleus and cytoplasm. The pores are 9 nm in diameter and each is surrounded by a pore complex that consists of eight large protein granules arranged in an octagon.

Nucleolus The nucleolus is a region within the nucleus that begins the assembly of ribosomes—tiny organelles that serve as the sites of protein synthesis. Toxic products such as hydrogen peroxide H 2 O 2 are formed as a result of cellular reactions within the cell. The peroxisome isolates these peroxides from the rest of the cell and safely breaks them down.

In addition to other functions, the plasma membrane regulates the ions and molecules that enter and leave a cell. It consists of a phospholipid bilayer embedded with proteins and other molecules.
