As energy moves through an ecosystem,

9.40_Q1) Which particle moves through a metal wire as electricity?

bija089 [108]

Answer No 1:

The correct option is Electrons.

Electrons are the negatively charged particles of an atom. They revolve around the nucleus of an atom. In circuits, electricity is carried by the electrons which move through a wire. Hence, option C is the correct option.

Other options like option A are not correct because protons are the positively charged particles of an atom. They are present in the nucleus of an atom and hence, do not generate an electric current.

Answer No 2:

Electrons move through the circuit from the negative power terminal to the positive power terminal.

Electrons make up the negative charged particles of an atom. They are involved in the conduction of electricity in circuits. In a circuit, the current flows from a negatively powered terminal to a positively charged terminal. This is known as the electron flow. Hence, option A is correct.

Answer No 3:

The correct option is B) Current

The movement or flow of electrons or electric charge is termed as electric current. Whenever a circuit is completed, current is generated.

Other options like option C, resistance are not correct because resistance is the force which opposes current flow.

Answer No 4:

The correct option is A) Voltage

Voltage can be described as the force which causes electricity to flow in a circuit. Hence, option A is correct.

Other options like option C are jot correct because resistance is the force which opposes the flow of current.

Answer No 5:

The correct option is C) resistance

Resistance can be described as the force which opposes the flow of current. Resistance can be measured in ohms. It can be described as the difficulty which electrons have in moving through a circuit.

Other option like option A is not correct because voltage is the force through which current is generated.

Answer No 6:

The correct option is C amps

The S.I unit through which current is measured is called amperes. The symbol for amperes is A. Hence, option C is the correct option.

Other options like ohms are not correct because ohms is the S.i unit for resistance.

Answer No 7:

The correct option is A) volts

The S.I unit for voltage is volts. Voltage can be described as the potential difference which is present in a circuit. Hence, option A is correct.

Other options are not correct because amp is the unit of electric current and ohms is the unit for resistance.

Answer no 8:

The correct option is C) ohms

In physics, resistance can be described as the force which opposes the motion of electrons or electrical current. The S.I unit for resistance is ohms. Hence, option C is correct.

Other options like option A is not correct because volts is the S.I unit of velocity. Option B is not correct because amps is the unit for electric current.

Answer No 9:

The correct option is C) The voltage is decreased because of the electrical resistance.

According to ohm's law electric current is directly proportional to electric current and inversely proportional to electric resistance.

So, when the resistance increases, the voltage decreases.

I have mutant cells that make no pfk2enzyme. i measure rates of oxygen consumption in these mutant cells and compare them to wil

Kazeer [188]

The correct answer is that mutant cells will exhibit diminished oxygen consumption; decreased glycolysis results in decreased Kreb's cycle and electron transport chain.

The PFK2 enzyme catalyzes the generation of F26BP, this binds with the allosteric site of PFK-1 and increases the affinity of PFK-1 with F6P and also decreases the affinity of allosteric inhibitors citrate and ATP to PFK-1. Thus, PFK-1 will combine with F6P at a greater rate.

This ultimately results in more glycolysis, thus, more ETC and more consumption of O2. If there is no PFK2, then there will be a reduction in glycolysis, TCA, ETC, and consumption of oxygen.

The PFK2 is an enzyme accountable for monitoring the rates of gluconeogenesis and glycolysis in the human body. In the absence of glycolysis, there will be a reduction in TCA, ETC, and consumption of O2.

How do mutation drive evolution ?

Korvikt [17]

Answer:

Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele.

evablogger [386]

Answer:

1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.

2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged. Electrostatic interaction also depends upon the nature and mass of body.

b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.
