The physical characteristics of an organism are its
Answer:
appearance, development, and behavior
Explanation:
The phenotype, similar to the genotype, can be observed in two senses: wider and narrower. In a broader sense, a phenotype is a set of all morphological and physiological properties by which an organism is recognized and by which it differs from other organisms.
When we look at only one trait, then it is the narrower meaning of the phenotype. What will be the influence of genotype on phenotype depends not only on the genetic basis but also on the action of environmental factors in which the organism develops.

Fungi, Animalia, Plantae, and Protista
Explanation:
Fungi: A cluster of organisms that produce spores and feed on organic matter, examples are Mushrooms, mold and yeast.

Plants: organisms such as grass, trees, moss, flowers, and grow in the same spot. They absorb water, and inorganic matter through their roots, and usually have green coloring to do photosynthesis.
Protists: These organisms are usually microscopic and unicellular. They contain a nucleus and other specialized organelles, and some can move around. They vary widely of what they do, with some like Amoebas moving and eating other cells, while algae stay put and perform photosynthesis.

explain how the microscopic fixation of nitrogen can have such a large impact on life?
The N2 must be changed through a procedure known as nitrogen fixation. Fixation transforms atmospheric nitrogen into forms that plants' root systems can absorb.
What is nitrogen fixation?Nitrogen fixation is defined as a chemical process that turns airborne molecular nitrogen, which has a powerful triple covalent bond, into ammonia or other related nitrogenous chemicals, usually in aquatic or soil systems but also in industry. In order to give plants access to a vital nutrient that they are unable to naturally obtain from the air, nitrogen-fixing bacteria are used.
Since plants and animals cannot directly utilize atmospheric nitrogen, this mechanism is crucial. Although N2 gas makes up 78% of the atmosphere, most organisms cannot utilize it directly since it must first be transformed into another form. It is transformed into ammonium (NH4+) by bacteria, which plants can subsequently absorb.
Thus, the N2 must be changed through a procedure known as nitrogen fixation. Fixation transforms atmospheric nitrogen into forms that plants' root systems can absorb.

This is a negative charge. On the left draw the type of charge that would move away from it. On the right, draw the
type of charge that would move towards it.
(This is science)
Answer:
On the left is negative charge while on the right is positive charge.
Explanation:
On the left, there should be negative charge that will move away due to repulsion force because both charges are same so they move away from one another while on the other hand, on the right side there should be positive charge which will move towards it because both charges are opposite to each other so they attract each other.

sword making is
tensile strength

strength
conductivity
NEXT QUESTION

ASK FOR HELP
TURN IT IN
Answer:
The property that makes steel a good choice for sword-making is strength
Explanation:
The strength of a material is its ability to withstand an applied load or force without failure or plastic deformation. Types of strength of materials include; tensile strength, yield strength, torsional strength, compressional strength, shear strength.
Tensile strength of material is the ability of that material to withstand any force that tends to break or tear it apart. It is calculated by dividing the maximum amount of load or force the material can carry or withstand without breaking by the surface area of the material.
Mathematically, Tensile strength = Force/area
Its unit is Newton per meter squared, N/m².
Yield Strength In Steel
Yield strength is the maximum stress that can be applied before it begins to change shape permanently. Yield strength represents the upper limit of the load that can be safely applied to the meta beyond which it shape deforms.
Steel is an alloy of iron and carbon. It has many important and desirable properties such as durability, hardness and conductivity, and high tensile strength. However, the high strength of steel made a good choice for sword-making in the ancient past and even in the present.

What characteristic of water causes water to stick to the side of a test tube?
I need a claim, evidence, and reasoning !
Answer:
The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).
Explanation:
Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.
- Claim: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.
- Evidence: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.
- Reasoning: cohesion in water depends on the force of attraction between H₂O molecules, adhesion is the capacity of H₂O molecules to join other different molecules and —together with surface tension— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.
The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

Answer: A current, in a river or stream, is the flow of water influenced by gravity as the water moves downhill to reduce its potential energy. The current varies spatially as well as temporally within the stream, dependent upon the flow volume of water, stream gradient, and channel geometry.
Explanation:
Answer:
Currents help the water in rivers and streams flow downhill, with the ultimate goal of flowing into the oceans, which are at sea level.

Compare the functions of the circulatory, respiratory, and nervous system in gas exchange
Answer:
Functions of the circulatory, respiratory, and nervous system in gas exchange are interconnected with each other in the following manner:
The circulatory system is responsible to pumps blood around the body. The circulation system allows the absorption of oxygen and releases carbon dioxide in the lungs and the Respiratory system also take oxygen in and releases carbon dioxide. The circulatory system and respiratory system work hand in hand. The brain or nervous system monitors gas or oxygen level in blood and regulates respiratory rate.
