A spring-fed stream forms a pond that contains watercress plants, minnows, and crayfish. The pond receives 5 hours of direct sunlight every day. Which of the following is an abiotic factor in this ecosystem?
the pond water

the watercress plants

the minnows

the crayfish

Answers

Answer 1

Answer:

the minnows

Explanation:

Answer 2

The minnows is an abiotic factor in the ecosystem Hence option 3 is correct.

What is ecosystem?

Ecosystem is defined as a structural and functional area of ecology where living things engage in interactions with one another and their surroundings. Ecosystem function refers to a system's capacity to directly or indirectly satisfy human wants for goods and services. Ecosystem functions are thought of as a subset of ecological processes and ecosystem structures.

The non-living elements of an ecosystem known as abiotic variables have an impact on their surroundings. Examples include temperature, light, and water in a terrestrial setting. Ocean currents and salinity are examples of abiotic components in a marine ecosystem.

Thus, the minnows is an abiotic factor in the ecosystem Hence option 3 is correct.

C. The rate of the reaction begins to decrease as reactants are used

O

D. The rate of the reaction stays constant until the reactants are

gone.

Answers

The rate of the reaction depicts the speed at which the reaction occurs to produce the products. As the reactants get used up the reaction rate starts decreasing. Thus, option C is correct.

What are the factors affecting reaction rate?

The reaction rate of the chemical reaction gets affected by numerous factors that include temperature, the concentration of the reactants, catalyst, surface area, and physical state of the reactant.

The concentration of the reactant has a direct effect on the reaction rate as they are the deciding factor of the product formation. At the beginning of the reaction, the speed is fast compared to the end.

As the reactants start getting used up the reaction rate slows down as the molecules are not able to collide faster with other molecules to form the product.

Therefore, in option C. the reaction rate decreases with a decrease in concentration.

What role does the Sun play in the interaction of energy during photosynthesis? What forms of energy conversion occur? What form does the chemical energy take? What gas do plants release as a result?): so i have no clue how to write it .?.?.?.?.?.?
.

Answers

Answer:

1 . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.

2. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.

3.Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.

4 . Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.

THE answer IS B)cu(s)

Explanation:

HOPE ITS HELP

The metal reacts spontaneously with aqueous solution of NiCl₂ is Zinc as it is more reactive.

What is reactivity series?

Electro chemical series is a reactivity series which tells about the reactivity of the metals present in any solution in the increasing order.

According to the reactivity series, Zinc is present at the upper position as compares to other three given metals and their reactivity will be represented as:
Zn > Ni > Sn > Cu > Au

So, zinc will replace the nickel atom from NiCl₂ solution.

Answer:

Aerobic respiration is metabolic process in which food ( glucose) is metabolized ( in presence of oxygen) to derive large amount of energy ( in the form of ATP) through a series of three stages that is glycolysis, kreb cycle, and electron transport chain.

Anaerobic respiration another from of cellular respiration where food is broken down to derive energy in the absence of oxygen.

Lactic acid fermentation is a metabolic process by which glucose is converted into cellular energy and lactic acid.

Thus, the correct match is-

Aerobic respiration- A) The breakdown of food to create energy in the presence of oxygen.

Alcoholic fermentation- C) A process that converts sugars into cellular energy, ethanol, and carbon dioxide.

Anaerobic respiration- B) The production of energy without the presence of oxygen.

Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.

In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.

The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.

Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

Answers

Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.

Explanation:

Option A is correct. The statement that best describes the motion of  the dye molecules in the water is "the dye molecules move in a directed way from high to low".

The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".

The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).

In conclusion, the statement best describes the motion of  the dye molecules in the water is "the dye molecules move in a directed way from high to low".
