Answer:
He proved that an organism inherits alleles ("factors") that control which traits are expressed and that these alleles could be dominant or recessive.
the sense of equilibrium maintains the stability of the head and body when they are motionless. the sense of equilibrium balances the head and the body when they are suddenly moved or rotated.
The sense of static equilibrium maintains the stability of the head and body when they are motionless. The sense of dynamic equilibrium balances the head and the body when they are suddenly moved or rotated.
Static equilibrium occurs when a body is at rest. There are two forces acting upon the body during static equilibrium, but they occur in opposite direction, and as a result the body remains static. For example, when an organism stands still in its position, it is acted upon by the force of gravity downwards and normal force upwards and thus remains in static equilibrium.
Dynamic equilibrium occurs when a process is going on. It detects the angular acceleration of the movement of head. In humans, the semicircular canals help in maintaining the dynamic equilibrium.

Define osmosis and explain why it biologically important.
Explanation:
osmosis
refers to the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules through a cells partially permeable membrane
Importance
- it stabilizes the internal environment of the organism by balancing the level of water and intracellular fluids
General category: Biology.
Sub-category: Cellular membranes
Topic: Diffusion
Introduction:
Diffusion is the random movement of molecules in a given medium toward a state of equilibrium. Then, diffusion is the net movement from regions of greater concentration to regions of lesser concentration.
Explanation:First of all, remember that if a cell membrane divides a solution into separate compartments, the movement of the different solutes can be affected by the properties of the membrane. The passage of substances depends on whether the membrane is permeable or semi-permeable to different solutes.
Now, the concept of osmosis is based on the idea of diffusion. Osmosis is the diffusion of water across membranes. This means that water will diffuse from a region of its higher concentration (lower concentration of solutes) to a region of its lower concentration (higher concentration of solutes).
Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function. Remember that osmotic equilibrium is the ratio of intracellular fluid to the extracellular fluid. For example, osmotic balance is of vital importance in the functioning of the nephron.
We can conclude that the correct answer is:
Answer:Osmosis:
Osmosis is the diffusion of water across membranes where the water will diffuse from a region of its higher concentration to a region of its lower concentration.
Biological importance of osmosis:
Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function.

2. During an activity, a teacher labeled the following scenario as hypertonic. Is she correct? Why or why no
%H₂0
15%
solute
80% H₂O
% solute
Correct. The solution in the beaker is hypertonic to the cell interior because its solute concentration is about 20%, which is greater than 15%. Water tends to leave the cell.
What are hypotonic and hypertonic solutions?When placing two solutions together separated by a membrane, we can classify them according to their solute concentration,
A hypertonic solution is the one with the higher solute concentration. It is the most concentrated solution.
A hypotonic solution has lower solute concentrations. It is the most diluted solution.
Isotonic solutions have the same solute concentrations.
In this example, we will assume the circle is a cell,
Cell interior ⇒ 85% water + 15% soluteBeacker solution ⇒ 80% water + 20% soluteThe solution in the beaker is hypertonic to the cell interior because its solute concentration is about 20%, which is greater than 15%.
The interior of the cell is hypotonic to the solution in the beaker, because it is more diluted. It has 85% water, which is higher than 80% water. Water tends to leave the cell moving forward to the beaker solution.

Which body fluid compartment contains high levels of k , large anions, and proteins?
Intracellular fluid contains high levels of k , large anions, and proteins.
What is Intracellular fluid?Fluids are bathed inside and outside of human cells. In actuality, the water that is present inside each cell accounts for 42% of the body's weight. Intracellular fluid is the term for the fluid found inside cells (ICF). Extracellular fluid (ECF), which refers to all fluid present outside of the cell, is distinguished from intracellular fluid by the semipermeable membrane that encloses it. This membrane permits fluid to pass through and leave while blocking the entry of undesirable chemicals or components. Water, proteins, and dissolved solutes are all present in intracellular fluid. The solutes are electrolytes, which support the healthy operation of our body.

Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose molecules in cellulose. how then do cows get enough nutrients from eating grass?
Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.
Cellulose- The stable formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharide) made up of cellulose chains make up the plant cell wall.
Glucose- The primary form of sugar in the blood, glucose serves as the body's cells' principal source of energy. Glucose may be produced by the body from other chemicals or it can be obtained from the meals we eat. The circulation carries glucose to the cells.

Explanation:
Each species of the eukaryotic category of organisms, which also covers the more well-known mushrooms and microbes like yeast and mold, is referred to as fungi. Apart from the different other eukaryotic kingdoms, which according to one classification contain Plantae, Animalia, Protozoa, as well as Chromista, these species are categorized as a kingdom.
Chitin in their cell walls distinguishes fungi mostly from plants, bacteria, as well as certain protists, putting them in a unique kingdom. Like mammals, fungi consume dissolved substances by absorbing them; normally, they do this by releasing digestive enzymes towards their surroundings. The majority of fungi are not toxic, however some of them can be. There are two types of fungal infections: primary and parasitic.

Describe the process of how heat transfers from within the Sun starting in the core and moving outward.
Answer:
Hope it helps
Explanation:
The energy produced through fusion in the core moves outward, first in the form of electromagnetic radiation called photons in the so-called radiative zone. Next, energy moves upward in photon heated solar gas. This type of energy transport is convection. In other words, energy is radiated out from the core first, then carried to the outer layers by convection. Energy is carried out from the core by convection first, then radiated to the outer layers.

Peptide bonds are the type of bonds that maintain the primary structure of a protein.
Which bonds maintain the primary structure of a protein?
Peptide bonds are specific type of bonds which connect two or more amino acids together in order to maintain the primary structure of a protein. A peptide bond is also called eupeptide bond. This is a chemical bond that is formed by combining the carboxyl group of one amino acid to the carboxyl group of another amino group. We know that protein is made up of amino acids which are the building blocks of protein. Without this bond, protein molecule can not formed because amino acids are unable to combine together.
