How would you identify a floodplain that has not been immersed for a long time?

Answers

Answer:

Floodplains are identified as zones on FEMA Flood Insurance Rate Maps (FIRMs). Flood zones are defined by type, depth, and frequency of flooding. But the shape and nature of a floodplain may also change over time as the main channel of a river naturally migrates through erosion and accretion, impacting how and where excess water may first over top the banks of the river during a flood event. Geologically ancient floodplains are often represented in the landscape by fluvial terraces. These are old floodplains that remain relatively high above the present floodplain and indicate former courses of a stream. I HOPE THIS HELPS YOU :)

Explanation:

The geology of a floodplain the natural development of floodplains is primarily influenced by two processes: aggradation and erosion which help to identify that it has not been immersed for a long time.

What do we should know about floodplain ?

The flood fringe extends beyond the floodway. From the floodway's outer banks to a river valley's bluff lines, the flood fringe extends. The point at which the valley floor begins to rise into bluffs is marked by bluff lines, which are also known as valley walls.A generally flat area of land adjacent to a river or stream is known as a floodplain. It extends from the riverbanks to the valley's outermost edges. There are two components to a floodplain. The floodway, which is the river's primary channel, is the first. The channel may be dry for a portion of the year in floodways, which can sometimes be seasonal.The process by which earth is worn away by the movement of a floodway is referred to as the erosion of a floodplain. The term "aggradation" of a floodplain refers to the process by which earthen material expands as sediment is deposited by the floodway. A floodplain is eroded by a river as it meanders or curves.Floodplains are frequently made up of features like oxbow lakes and seasonal wetlands. These features are the result of erosion and deposition.A floodplain's erosion and aggradation, or accumulation of land elevation, may be exacerbated by a meandering stream. A river that is wide, shallow, and braided is a typical aggradation environment. River deltas, where the main floodway is divided into discrete channels and tiny islands, are frequently found in braided rivers.

The four major classes of biomolecules are carbohydrates, lipids, proteins and nucleic acids. These biomolecules are fundamental for the functioning of all biological systems.

Molecule: carbohydratesDescription: complex carbohydrates are polymers composed of many subunits called monosaccharides (i.e., simple carbohydrates) linked by glycosidic bonds.How Used by Living Things: structural and energy roles. Complex carbohydrates provide a more lasting energy source in the body than simple carbohydrates.

Molecule: lipidsDescription: lipids are a broad category of biomolecules that may be composed of one or more fatty acid chains and a glycerol backbone. How Used by Living Things: lipids provide a source of long-term energy for cells, heat insulation, structural roles in the cell membrane (phospholipids and cholesterol, etc).

Molecule: proteinsDescription: proteins are polymers composed of a linear chain of amino acids linked by peptide bonds.How Used by Living Things: proteins have structural (e.g.,  actin filaments) and enzymatic (e.g., catalase) functions.

Molecule: nucleic acidsDescription: nucleic acids (DNA and RNA) are polymers consisting of long chains of nucleotides.How Used by Living Things: DNA contains the hereditary information which is required to synthesize any protein. RNA serves as a transition molecule that helps to regulate the type and amount of proteins in cells.

1. Which of the following scenarios would not prompt the cell to start dividing? A. a bone elongating during puberty B. tissue healing after an injury C. stretching of a cell to allow for more fat storage

Answers

Answer:

I think the answer is C

Explanation:

The scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

What do you mean by Cell division?

Cell division may be defined as the process by which a parent cell divides into two or more daughter cells.

The stretching of a cell to allow for more fat storage is usually done by the process of cell growth, but not by the process of cell division.

Therefore, the scenario that would not prompt the cell to start dividing is the stretching of a cell to allow for more fat storage.

What term is used to describe the state at which a solute moves down its concentration gradient
through the plasma membrane and becomes evenly distributed in the cytosol?

Answers

4.solvent I’m pretty sure

Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.

What is Diffusion?

Diffusion is the type of net movement of particles from an area of ​​higher concentration to an area of ​​lower concentration. It is driven by the gradient in Gibbs free energy or chemical potential.

This occurs through the semi-permeable membrane like the plasma membrane. Diffusion of small molecules and macromolecules such as proteins in aqueous solutions plays an important role in microorganisms, plants and animals.

Few examples of Diffusion are:

Perfume is sprayed in one part of the room so that it can spread easily so that we can feel its smell everywhere. A drop of food coloring spread throughout the water in a glass, the whole glass will be colored.

Thus, Diffusion is used to describe the condition at which a solute moves down its concentration gradient through the plasma membrane and becomes uniformly distributed in the cytosol.

why organisms need specialised cells and tissues in order to survive

Answers

why organisms need specialized cells and tissues in order to survive;

the cells get oxygen and nutrients from this extracellular fluid and release waste products into it. Humans and other complex organisms have specialized systems that maintain the internal environment, keeping it steady and able to provide for the needs of the cells.

systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules.

Multicellular organisms require cells to perform various functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures become specialized for specific functions.

What is cell specialization?

Cell specialization, also recognized as cell differentiation, is the methodology by which formulaic cells transform into specific cells that perform specific functions within the body.

Cell specialization is especially important during embryonic development.

Cell specialization allows multicellular organisms to express fewer genes in individual cells, protecting genes from mutagen damage.

Cell specialization occurs primarily during embryonic development as a result of cell signaling of cytoplasmic determinants.

Adult stem cells become specialized to various types of stem cells primarily due to gene expression regulation.

Cells in multicellular organisms must perform a variety of functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures evolve to perform specific functions.

Thus, the organisms need specialized cells and tissues in order to survive.

A student observes a cell under a microscope. She sees a cell wall and a nucleus. What type of cell is she observing?
O eukaryotic animal cell
O eukaryotic plant cell
O prokaryotic cell
O bacterial cell

Answers

Answer:

eukaryotic plant cell

hope this helps

Only eukaryotic plant cells have a cell wall and a nucleus. Option 2 is correct.

Eukaryotic cells are cells that have a nucleus and other membrane-bound organelles. Prokaryotic cells do not have a nucleus or other membrane-bound organelles.

Plant cells are eukaryotic cells that have a cell wall. The cell wall is a rigid structure that surrounds the cell membrane. It provides support and protection for the cell. Animal cells do not have a cell wall.

The nucleus is the control center of the cell. It contains the DNA, which is the genetic material of the cell. The nucleus also contains proteins that control the activities of the cell.

So, if a student observes a cell under a microscope and sees a cell wall and a nucleus, she is observing a eukaryotic plant cell.
