Answer:
B. Voltage is when current flows from higher to lower potential energy.
Explanation:
Voltage refers to the difference in electric potential between two points. Current in the wire always flow from higher potential to lower potential due to voltage. At the electric source, voltage of current is high but when it moves through wire, the amount of current decreases when it reaches to the other end of the circuit. This is because of the resistance present inside the wire which causes heat energy and some of the current is lost.
The correct answer is option B. Voltage is when current flows from higher to lower potential energy.
What is voltage?
Voltage is the difference in charge, in this case, made by the electrons, that results in electrons flowing from a place of high concentration to one of low concentration. We call the flow of electrons current, and we measure voltage in Volts (V).
What is Amperes?It is a unit that we use to measure the intensity of the current.

How does crossing over create new gene combinations on each chromosome
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
Answer:
Crossing-over

The movement of water from an area of high water concentration to an area of low water concentration is . osmosis,diffusion,active transport or stable transport
Answer:
Explanation:

how has paraquat stopped the algae from making atp nadph and sugars
Answer:
This is by disrupting the mechanisms of photosynthesis.Paraquat is an herbicide. A photosynthesis inhibiting herbicides. In the light dependent reaction, It acts as oxidizing agent by accepting electrons from Photo system I. and lose these electrons to oxygen molecules which becomes oxidized.
Therefore, disrupting the electron transport chain.With the electron transport chain disrupted, PMF is inhibited, electrochemical gradients for generating energy for ATPs synthesis, by ATPase synthase enzyme is blocked.
Therefore, ATPs synthesis is prevented. With this, Calvin Cycle is blocked, so no CHO id formed. With lack of electron transport chain, NADPH will not be formed. .

Answer:
A.
Explanation:

What do you mean by gene expression?Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect.
Gene expression is the process by which the information encoded in a gene is turned into a function. This mostly occurs via the transcription of RNA molecules that code for proteins or non-coding RNA molecules that serve other functions.
Gene expression is a tightly regulated process that allows a cell to respond to its changing environment. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.

Which part of the neuron below is indicated by the arrow, and what is its function? The long section of a neuron that includes structures that wrap around the neuron are indicated by the arrow. The axon carries information through electrical impulses away from the cell body to the axon terminals. The axon contains the nucleus that controls all the activities of the cell. The dendrites regulate the substances that go in and out of the cell. The dendrites carry the electrical impulses from the signal receivers to the cell body.

Which component of a DNA synthesis reaction determines the exact nucleotide sequence of the product?
Answer:
The complementary base pairing between incoming nucleotides and the DNA template
Explanation:
In a DNA synthesis reaction, the exact nucleotide sequence of the product is basically determined by both the DNA template from which a new strand is made and the incoming new nucleotides that makes up the new DNA strands. A complementary base Paris between these two gives the nucleotide sequence of the product.

Experiment: Water Properties: Why were the results with just water so much different than the trials with the detergent?
Answer:
Explanation:
Water is a universal solvent whose molecule are joined together with a force of attraction. Its surface tension is hidden between bonds. When washing, soap is added for easy penetration of water molecule and to decrease the surface tension. This then allow the water to move freely round the object been washed.
Detergent aid the distribution of water, of water is used alone without the detergent then the surface area of water will not be reduced to all even spread. But, if detergent is added the tension is reduced and a better result is obtained.

Fish that live in murky water most likely have larger, more developed ___. dorsal fins. olfactory lobes. rosettes. pharyngeal teeth.
Answer:
olfactory lobes
Explanation:
The correct answer would be olfactory lobes.
Murky waters are generally dark, and contains very little (low) light. Fishes that live in murky water need to be specially adapted in order to be able to live in such environment. These adaptations could be in terms of:
A well developed lucidum tapetum, a layer of protein crystals known as guanine which enables them to see through low light and act as a kind of 'night vision'.A well developed olfactory lobe which receives and process information from the olfactory nerve with high efficiency and generally serves to improve the sense of smell.which of the choices below is NOT a way in which carbon dioxide is transported in the blood

Which statement is true of DNA polymerase?
Answer:
b) DNA polymerase can synthesize DNA in the 5' to 3' direction
DNA polymerase is only able to synthesize a new strand of DNA and not mRNA. It is only able to do this in the 5' to 3' direction. The leading template strand runs in the 3' to 5' direction and so the new complementary strand is synthesized in a 5' to 3' direction in one continuous run, following the replication fork as it 'unzips' the DNA.
