Answer:

Diffusing molecules move <u>down the concentration gradient</u> until they are <u>evenly distributed.</u>

Explanation:

Diffusion is the process of transport of substances down the concentration gradient in a passive way. During the process, the substances move from the region of higher concentration to the region of lower concentration. The process continues until the substances are equally distributed throughout the given system. The process does not need energy input as the concentration gradient drives it.

Answer;

-Down the concentration gradients; evenly distributed

Diffusing molecules move down the concentration gradients until they are evenly distributed.

Explanation;

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.

-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.

-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.

10. The authors of the textbook present the 9 fielders of a baseball team as a model of cells in
Dvinal [7]

Explanation:

The cells of multicellular organisms are interdependent, and like the members of a successful baseball team, they work together.In baseball, players take on a particular role, such as pitcher, catcher, infielder, or outfielder. Messages and signals are sent and understood by teammates and coaches to play the game effectively.

Cells in a multicellular organism work the same way. The cells of multicellular organisms become specialized for particular tasks and communicate with one another in order to maintain homeostasis.

<em>Further Explanation:</em>

<em />

<em><u>1. The model outlines each cell’s specific role, related to their function such as a pitcher, catcher, infielder, or outfielder etc.</u></em>

The structures of cellular organelles are related to their functions: The structures of cellular organelles are related to their functions. Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle.

In all eukaryotic cells mitochondria are small cellular organelles bound by double membranes make most of the chemical energy required for powering the biochemical reactions within the cell. this chemical energy is stored within the molecule ATP which is produced

Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they

  • may increase metabolic reaction efficiency;
  • they allow cells to concentrate smaller fractions of enzymes and solutes separate proteins and molecules that may harm the cells by parceling them into membrane-bound organelles
  • <u>for example, hydrolytic enzymes within vacuoles may degrade macromolecules like DNA and RNA within the cytoplasm.</u>

<em><u></u></em>

<em><u>2. The model shows that cells are interdependent, they must communicate, or work together to fulfill a goal...</u></em>

Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. They are interdependent, and work together like a team as tissue, within the human body these can generally be placed into four groups:

  • epithelial which refers to sheets of cells covering exterior surfaces and internal organs;
  • connective tissue which functions to bind cells and organs together while protecting, supporting and integrating different regions.
  • muscle tissue which responds to simulation, allowing for movement and locomotion;
  • nervous tissue which responds to electrical impulses, allowing for communication between different regions of the body

<em><u>3. The model places the coach as the brain or control center, where it regulates all activities related to homeostasis, just like a baseball game…</u></em>

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system (ANS) which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

Approximately 40% of the energy stored in sugar molecules is converted into energy. What happens to the remaining 60%?
Vaselesa [24]
<h3>Answer</h3>

Approximately 40% of the energy stored in sugar molecules is converted into energy and the remaining 60% is wasted as heat energy.

<h3>Explanation</h3>

Cellular respiration is the process which take place inside a living organism by which organic compounds, usually carbohydrates, are broken down releasing energy that is used to produce ATP molecules that supplies energy/power to cells.

<h3>Example of respiration</h3>

C6H12O6 + 6O2 —– enzymes & coenzymes ——> 6CO2 + 6H2O + Release of Energy (≤38 ATP) + Heat

So, 40% of the available energy of glucose is release as ATP and the remaining 60% is lost as heat and helps to generate your relatively high body temperature.
